1, lodging prevention
Pay attention to wheat lodging after heading. Once lodging occurs in wheat, it has a great influence on yield. There are many factors that can easily lead to lodging, such as continuous heavy rain and strong wind, which can easily lead to lodging of wheat. Other diseases will also increase the probability of lodging of wheat, such as root rot.
Step 2 spray foliar fertilizer
Spraying foliar fertilizer has many advantages. First, it can provide nutrients for wheat growth, especially some medium and trace elements, which is beneficial to the increase of grain weight. Second, it increases the function of blades and reduces the harm of dry and hot wind; Third, improve the field filling rate of wheat, effectively increase grain weight and promote high yield of wheat.
water
There are different views on watering. Some people think that watering during grouting is easy to cause lodging, and this situation will exist. However, for relatively dry plots, watering is needed to promote the normal growth of wheat. During the whole growth period of wheat, from filling to maturity, the demand for water is relatively large, accounting for about 20%-25% of the whole growth period. If the field is too dry after heading, it will not only affect.
Step 4 weed control
I believe many friends will have different views on weeding during wheat filling. At this time, if herbicides are applied again, the probability of phytotoxicity will be greatly increased. In addition, the growth of wheat is higher than that of many weeds, and it is not easy to spray on weeds. So the weeding mentioned here is carried out when there are too many weeds in the field. Some fields may not be weeded in the early stage, or the weeding effect is not good, but the weeds are too dense during filling, which affects the normal growth of wheat. It is not necessary to weed manually to ensure the normal growth of wheat and improve the final yield. It depends on the specific situation. After all, artificial weeding is not practical in the case of large-scale planting.
The above four points are the management measures that need to be taken in the process of wheat filling, which have a good effect on increasing the number of grains per spike and improving the grain weight. Of course, in the actual planting process, everyone should choose their own measures according to the specific situation, and it is not necessary to implement them all.
May is the key period for the formation of wheat yield, and the filling stage is the key period for determining the 1000-grain weight of wheat. The management of this period directly affects the yield of wheat, so it is necessary to strengthen the management of wheat filling period.
In order to ensure high and stable yield of wheat, combined with the characteristics of wheat growth and development and the current wheat situation, I put forward the following management suggestions, hoping to be useful to everyone.
1, supplement nitrogen fertilizer and pour slurry water.
At this time, wheat is in flowering stage. After 10- 15 days, about 5 kilograms of urea should be applied topdressing per mu, and the grouting time should be prolonged in combination with watering and washing. But if you know that the wind and rain are coming, you can't water it to prevent lodging, and you can't topdressing too much nitrogen fertilizer to prevent greed and late ripening.
If the base fertilizer is sufficient, topdressing nitrogen fertilizer in spring, at this time, spraying 200g of potassium dihydrogen phosphate and 500g of urea on the leaves, 30-40 kg, and spraying again after 7- 10.
2, pest control
With the increase of temperature and humidity, wheat powdery mildew, rust, aphids, red spiders, wheat sawflies and other diseases and insect pests will occur. At this time, we must do a good job of spraying three or four defenses to prevent diseases, pests, dry and hot winds and lodging.
Wheat powdery mildew will harm wheat leaves, lead to photosynthesis failure and reduce yield. The flag leaf and the inverted second leaf of wheat are seriously damaged, and the yield will be greatly reduced, and it is easy to lodging and increase the number of grains.
Wheat rust also harms leaves, stems and ears, which directly affects the yield.
Triadimefon, also known as triadimefon, can be used for diseases and has special effects on wheat powdery mildew and rust. There are carbendazim, tebuconazole, propiconazole and so on.
Aphids can suck away leaf juice and grain pulp, resulting in a 20-30% decline in yield, which can reach more than 50% in severe cases.
Available chemicals include imidacloprid, acetamiprid, abamectin, pyridaben, beta-cypermethrin, etc.
The above-mentioned chemicals for controlling wheat diseases and insect pests can be used alternately, and at the same time, adding brassinolide can improve the strength of wheat stalk, reduce the harm of dry-hot wind, and enhance the filling speed, which plays an important role in improving the 1000-grain weight and grain quality of wheat.
How to manage wheat during grain filling period to achieve high yield?
During wheat filling, two things should be done well, water management and disease prevention, in order to obtain high yield. Water management is particularly important in wheat filling period, rainy or spring drought. There are many spring rains, high temperature in late spring and early summer, and serious water accumulation in wheat fields, which is not conducive to wheat irrigation. It will induce premature senescence of wheat roots, affect grain filling, and also cause diseases such as wheat scab and stem rust. If there is a spring drought, it will affect the water demand for wheat filling, make the grain filling insufficient and have more grains, and affect the quality and yield of wheat.
The first is water management during wheat filling. During wheat filling period, we are not only afraid of rainy, waterlogging and diseases, but also afraid of the coming of spring drought, which will affect grain filling. During the wheat filling period, if there is too much spring rain, remember to manage the wheat field, ditch and clear the ditch, repair the drainage channel from the wheat field to the outside, dredge and remove impurities to prevent blockage; Repair every drainage ditch in the wheat field to improve the drainage effect and enhance the ability to filter water and stains. Do it rain, there is no water in the wheat field, reduce the soil water content in the wheat field, and avoid causing root rot of wheat and inducing scab and rust. If the spring drought comes, the soil water content in the wheat field will be reduced. In order to avoid affecting the wheat filling, irrigation should be done immediately, and quickly, instead of slowly flooding.
The second is the prevention and treatment of wheat diseases during grain filling. Wheat filling stage is a season of high temperature and high humidity, and it is a high incidence period of wheat scab and stem rust. The key period of chemical control of scab and stem rust is from flowering to filling stage of wheat. Wheat scab should be sprayed for the first time at the flowering stage of wheat, at the latest before flowering, and generally sprayed for the second time every 7 days. At present, there are 50% thiophanate-methyl WP 1000 1500 times solution, or 50% carbendazim 1000 1500 times solution, or 40% mirex gel suspension1000. The best chemical control period of stem rust is generally spraying at the flowering and filling stage of wheat. The effective agents for controlling wheat stripe rust are sodium antirust agent, rust powder and triadimefon.
In short, wheat must grasp two points during grouting, manage water well and prevent diseases. If these two points are done well, a bumper harvest and high yield are inevitable.
Today is May 3rd in the solar calendar, and the wheat is about to blossom! How can we make wheat stable and high yield in the coming wheat filling period?
In mid-May, wheat was sprayed with "one spray and three defenses". Because there have been several rains in eastern Henan during this time, the drought here has been greatly alleviated! For the current situation, I think our farmers here should spray "one spray and three defenses" pesticides in time!
Yesterday, my daughter-in-law just sprayed five acres of wheat in our house, high-fluorine cypermethrin+brassinolide+potassium dihydrogen phosphate+medium and trace element fertilizer+tebuconazole prochloraz! A * * * spent nearly 50 yuan money! Because I contracted land planting a few years ago, I am familiar with the owner of agricultural stores and the price is more favorable! 5 mu of land was sprayed with 6.5 barrels of water! The rest is sprayed into the garlic field! If conditions permit, you can also use polonium to apply urea to wheat, with an area of about 20-25 kg per mu! Wheat really needs fertilizer during grouting, and the soil moisture here is better this year.
You can also spray bactericide+potassium dihydrogen phosphate+urea every other week! At this time, foliar spraying fertilizer can also increase wheat yield!
Warm spring is coming and hot summer is coming. With the increase of temperature, wheat basically entered the filling stage. The management of wheat during grain filling period plays an important role in improving wheat quality and yield.
So how to manage the wheat filling period to achieve the goal of high yield?
When wheat enters the grain filling stage, the growth of wheat needs to absorb a lot of nutrients and water. Therefore, the management of water and fertilizer in this period is particularly important. If there is no nutrition and water in this period, it will seriously affect the yield of wheat.
The soil in the wheat field is too dry or the humidity in the field is too high, and even water accumulation is not conducive to the growth of wheat. A few days ago, the boy's hometown was raining and windy continuously, and there was even hail in some places. Such weather has a great influence on the growth of wheat. Continuous rainfall makes the soil moisture in the field too high, which is very unfavorable to the respiration of wheat roots. Coupled with the strong wind, several wheat trees in the village fell down. If there is water on site, drainage should be carried out in time.
During wheat filling, it is necessary to avoid fertilizer removal and premature aging of wheat. In this period, due to the need for a lot of nutrition, the absorption of roots can not fully meet the growth needs of wheat, coupled with excessive soil moisture or diseases and insect pests and other factors, it is easy to cause premature aging of wheat. Under the condition of ensuring soil fertility, it is necessary to spray potassium dihydrogen phosphate on wheat in time, and the premature aging of wheat can be well prevented by supplementing phosphorus and potassium elements on leaves.
Do a good job of "one spraying and three prevention" to ensure high yield of wheat. Spraying potassium dihydrogen phosphate and brassinolide at wheat filling stage can make the roots and stems of wheat more robust, prevent premature aging of wheat and increase the ability to resist dry and hot wind, which is very important for improving the quality and yield of wheat. Adding thiophanate-methyl wettable powder or carbendazim can control wheat scab and stem rust; Adding chlorpyrifos or imidacloprid can control aphids, red spiders and other pests.
To sum up, the management of wheat filling period has an important influence on the quality and yield of wheat. Only by doing every job well can we ensure the high quality and high yield of wheat.
Wheat filling stage is the last important growth link that affects the final yield of wheat, so it is very important to manage it reasonably and scientifically during wheat filling stage. Then Lao Zhang told his fellow villagers what to do during the wheat filling period in order to increase the yield of wheat.
First, rational fertilization.
At this time, it is necessary to apply foliar fertilizer (0.5% potassium dihydrogen phosphate+1% urea+brassinolide mixture) to wheat. Spraying foliar fertilizer in time at this time is beneficial to prolong the senescence of wheat leaves, maintain the vitality of plants and maintain a high disease resistance. More importantly, it can improve the plumpness and dry weight of wheat grains.
Second, take timely measures to prevent pests and diseases.
Third, rational irrigation.
Generally speaking, irrigation at wheat filling stage is beneficial to increase wheat yield, but in actual production, we should pay attention to whether the growth of wheat is too strong. If it is too strong, it will easily lead to wheat lodging and affect the yield. Therefore, it is necessary to judge whether to irrigate wheat according to soil moisture and wheat growth. If it is half-watered, dip it in the ground and don't soak it for a long time.
The above are the methods given by Lao Zhang on how to scientifically manage and improve the yield of wheat during the grain filling period. Forgetting can help everyone.
With the change of season, it has entered the poplar flowering period of wheat, which is followed by the critical period of wheat management, which affects wheat yield. Because of the changeable weather, especially rainy weather and some irresistible bad weather, wheat diseases and insect pests will occur and affect wheat yield, so the management of wheat in this period is particularly critical.
First of all, what diseases and insect pests occurred during grain filling, mainly wheat rust, powdery mildew, scab and sheath blight. Once these diseases occur, it will have a serious impact on wheat, especially after rainy weather, which is the period when a large number of these diseases occur. If not controlled, they will spread rapidly in a short time. Because we all know that there will be a lot of wheat rust when harvesting wheat every year, and the reasons are all these diseases.
The main pests are ear aphid, wheat midge and wheat red spider. Especially in continuous rainy weather, ear aphids will occur seriously. The most important thing is to prevent and control wheat midge in time, and suck the grain slurry during wheat filling, which leads to grain shrinkage, empty shell and yield reduction. When it happens, the whole field will lose food.
Based on the above analysis, the most important thing for wheat at present is one spray and three defenses. Now, spraying three defenses at once can not only prevent and control the occurrence of wheat diseases, but also resist lodging and cope with bad weather at any time. As for the drugs for spraying foliar fertilizer, there is no unified regulation at present, mainly fungicides and foliar fertilizers to increase lodging resistance and disease resistance of wheat, and triadimefon and diniconazole are mainly sprayed to prevent powdery mildew and rust. Triadimefon, thiram and chlorpheniramine can control wheat root rot. If there are pests, pirimicarb or 40% omethoate and cypermethrin can be used to control wheat midge. Foliage fertilizer with potassium dihydrogen phosphate, brassinolide and amino acid as the main components should be used every time to resist diseases and increase production.
At present, there are many wheat-specific one-spray three-proofing agents on the market, and they also have good effects. It is recommended to buy from a reputable agricultural store. When spraying, it is best to use sunny days before 10 morning and after 4 pm, and the effect is the best.
First of all, thank you very much for your invitation. The filling period of wheat is the key period of grain formation, which determines the 1000-grain weight of wheat. However, under the premise of a certain number of ears and grains per mu, the growth of wheat in the key period will determine the final yield. Therefore, the management of grouting period is particularly important.
Generally speaking, the following two points should be done well during grain filling to lay a solid foundation for high yield of wheat. First, do a good job in water and fertilizer regulation. The increase of 1000-grain weight of wheat is actually the transfer of photosynthetic products, so it is very important to find ways to prolong the photosynthetic performance of leaves. Generally speaking, the grouting water should be poured at one time according to the soil moisture during grouting, and the amount of water should not be too large, about 20 cubic meters, so as to provide suitable moisture for grain grouting. It is best to irrigate slurry water in the middle of grouting, and irrigation must be stopped 10 day before harvesting. If the leaves are aging, a small amount of foliar fertilizer such as potassium dihydrogen phosphate should be added at the same time to prolong the green keeping time of the leaves and protect the photosynthesis.
If it is aquaculture, it is necessary to do the final purification and rejuvenation before harvesting.
The above are only personal opinions, and you are welcome to make more valuable suggestions.
Wheat enters the filling stage, which is also the key stage of wheat grain formation. Just like human insemination and pregnancy, it is a time to take care of and take in a lot of nutrition. Therefore, good fertilizer and water management and pest control are the key to determine wheat yield.
Farmers' friends are looking forward to good weather, but in case the weather is dry during the wheat filling period, they should also be properly watered. While watering, we must master a principle, that is, replenish water, and remember to flood.
The reality is that watering wheat at this stage is really a test for fields that still rely on water pipes to spray.
Then it is to supplement fertility. Of course, supplementing nutrition to wheat mainly depends on foliar nutrition intake. During this period, some foliar fertilizers can be sprayed, such as potassium dihydrogen phosphate+brassinolide+medium and trace elements, which is very important for wheat grain fullness and increasing the number of grains per spike and 1000-grain weight. Some farmers still have the habit of adding urea, which doesn't mean that urea can't be added at this stage, but we must master the dosage, otherwise it will cause the phenomenon of late maturity of wheat.
What are you most afraid of during wheat filling? Of course, it is the pests and diseases that are prone to occur in this period, especially rust and powdery mildew, as well as the harm of wheat midges and aphids. If the prevention and control work is not in place, it may seriously affect wheat yield.
We can add fungicides and pesticides to wheat when supplementing nutrition, which is also a good way to save labor and time.
It is suggested to use epoxiconazole+azoxystrobin or tebuconazole oxime proxetil in pesticide application, which can not only prevent wheat rust, but also prevent wheat powdery mildew and promote wheat growth.
The product combination of bifenthrin and thiamethoxam can be used as insecticide to control the harm of wheat midge and aphid.
At this time, the plant height of wheat has reached a certain level, and some pests and diseases also occur in the middle and lower parts of wheat. Therefore, when applying pesticides, we must pay attention to uniform spraying. In addition to selecting some pesticide products with strong internal absorption, at least 30 kilograms of water should be sprayed per mu. Only in this way can we have a good control effect.
At present, the growth of wheat in Guanzhong area is in flowering period, and wheat is self-pregnant, so the field management of wheat during pregnancy is very important. After the completion of pregnancy, wheat enters the most critical filling stage. At this time, farmers' friends must pay attention to the management of the field. Ready, ready to harvest wheat; If we can't do it well, we will definitely reduce production. In fact, in the field management of wheat planting in past dynasties, we found that the soil moisture in the wheat filling period must be good, and the water and fertilizer in the filling period can make the wheat grains full, otherwise it is difficult to make the wheat grains round. In fact, the high yield of wheat at grain filling stage is the result of comprehensive factors, although field management has primary and secondary points. As the technical guidance of the three rural issues, rural Guanzhong believes that the following aspects should be done well:
First, the soil moisture in the field must be good during the wheat filling period.
There is a proverb among farmers in Guanzhong: if the water is poured skillfully, the harvest is not afraid of ghosts. In other words, watering the wheat according to the soil moisture in the wheat field will also protect the wheat harvest. As we all know, the first day of May is the wheat filling period, which is the key period for the full gestation of wheat seeds and plays an important role in the high yield of wheat. Because the weather and temperature are rising at this time, the transpiration in the field is enhanced, and the metabolism of wheat plants is vigorous. If you water it in time during drought, you can ensure that the wheat grains are full. However, we must pay attention to the weather changes. If the weather is changeable during this period, in order to avoid lodging of wheat, watering must be stopped on windy days; Or when the wheat is growing vigorously, it is not suitable for watering, mainly to prevent the wheat from lodging. If the wheat lodging during this period, the yield reduction is basically determined.
Second, wheat should be supplemented with foliar fertilizer in time.
During this period, in order to effectively avoid the premature aging and degradation of the functions of leaves and roots of wheat plants, in the early stage of wheat filling, farmers' friends should apply fertilizer outside the roots or spray foliar fertilizer to supplement nutrient supply for the later growth of wheat. Farmers in Guanzhong area generally apply potassium dihydrogen phosphate, urea, calcium superphosphate water, etc. for foliar spraying, which can effectively prevent premature senescence of wheat leaves and dry hot wind, thus effectively improving wheat grain weight and increasing yield per mu. Rural Guanzhong noticed that many agricultural technicians advised farmers to spray a mixture of 0.5% potassium dihydrogen phosphate+1% urea+brassinolide at one time when they went to the countryside to guide farmers in the wheat heading and filling stage. Using this comprehensive drug effect, the functional period of wheat leaves is effectively prolonged, and it also has the functions of preventing premature aging, disease resistance and lodging, and the effect is very obvious. Farmers might as well try.
Third, farmers' friends should prevent and control pests and diseases in time.
According to many years of wheat operation experience, wheat filling stage is a high incidence period of many diseases and insect pests, which is very harmful to wheat growth in the later stage. During this period, the main pests were underground pests, such as wheat aphid, wheat spider, powdery mildew, rust and leaf blight, which directly threatened the increase of wheat yield and was also the key period for the increase of 1000-grain weight of wheat. Therefore, farmers should do a good job in pest control and try to use epoxiconazole+azoxystrobin or tebuconazole oxime proxetil for comprehensive management. Pesticides can be sprayed with 10% imidacloprid+avermectin mixture, and the amount of spraying liquid is about 45 kg per mu, and the spraying should be uniform, especially for the middle and lower leaves of wheat. This insecticide has obvious effect on preventing and controlling the above diseases and insect pests of wheat and the harm of wheat midge and aphid. This point must not be ignored by farmers.
Fourth, it is also crucial to prevent wheat from lodging.
During this period, the wheat will be top-heavy after filling, and the leaves of the next round of wheat will basically wither and turn yellow, or semi-wither and turn yellow. In addition to the change of soil moisture in the field, there are also reasons for the lack of fertilizer and water. At this time, the lower end of the wheat plant can no longer support the actual volume of wheat. As long as there is a slight wind in the field, wheat will lodging. Therefore, in the plain area, tall poplars should be planted around the wheat fields as windbreaks, which is also a reason that cannot be ignored.
Fifth, scientific treatment must strengthen the research of modern wheat planting technology.
In order to obtain high yield of wheat, we should not only do a good job in field management during wheat filling period, but also improve the technical level of wheat planting, which requires improving the scientific and technological farming ability of farmers' friends. Organizations at all levels should strengthen the training of farmers in agricultural science and technology, strengthen the training of farmers' friends in scientific wheat planting management technology and popularize farmland planting technology, and improve the scientific management level of wheat growth at all stages, which is the key to ensure high yield of wheat. Therefore, while respecting the experience of generations, farmers' friends must strengthen their own learning and guide themselves to improve field management operations with agricultural scientific and technological knowledge. Farmers' friends should take the initiative to learn new technologies and knowledge of scientific management, use new agricultural materials scientifically and rationally, and apply new technologies and measures of wheat field management to production practice to promote stable and high yield of wheat. This is the longest road, and farmers' friends must study harder.
