A small amount of fruit was produced in the second year after planting, and the normal fruit setting rate in the third year was 65,438+0,000%. After 4-5 years, the fruit yield per plant can reach 30-40 kg, and the yield per mu can reach about 2000-2500 kg. After normal management, the fruiting period reaches 20 years. Key points of cultivation: 1. Di Wei belongs to cross pollination, and the self-pollination rate is low. Select land, soil, water, climate, varieties and pollinated varieties, and allocate density according to planting plots. The garden has a large row spacing of 3m and a small row spacing of 2m, and the plant spacing is1m.. About 270 plants were planted on 667 square meters of land.
The yield per mu of Guizhou dinosaur egg plum is highly recommended. Peach trees have completed a production process after fruit picking, which consumes a lot of nutrients. At this time, nitrogen and phosphate fertilizer should be the main fertilizer, and nitrogen 1.5 ~ 2 kg and phosphate fertilizer 1 ~ 1.5 kg should be applied to every 50 kg of fruit, so that the root system is developed, the tree body is nutritious, the branches and leaves are abundant, and the wintering ability is enhanced.
Problems and Countermeasures in Early-bearing Walnut Production In recent years, the walnut industry has developed rapidly and the planting area of Early-bearing Walnut has expanded rapidly, which has played an important role in adjusting industrial structure, developing rural economy and increasing farmers' income. However, there are also some problems in walnut production:
① Early-fruiting walnuts are more susceptible to diseases, especially anthracnose, than late-fruiting varieties. Most early-bearing walnuts lost more than 30% of their fruits, and some orchards lost more than 50%.
First, prepare the flowerpot. Since we plant apple trees at home, flowerpots are essential in cities. Unlike rural areas, where there is soil at home and cement in cities, it is simply unrealistic to plant apple trees outside. You need to buy two flowerpots, one is smaller, and the other must be bigger, because you need to transplant apple trees when planting. After 5~7 sunny days, the inner bag will be removed. In the morning 10~ 12, it is advisable to pick the west and south crown paper bags and the east and north crown paper bags at 2~4 pm, which can reduce the occurrence of sunburn.
Moreover, when cultivating Toona sinensis seedlings, once covered with plastic wrap, there will be a seedling stage for half a month, which can increase the indoor temperature. However, the daytime temperature should be controlled at about 30 degrees, and it takes more than 30 days of natural temperature irradiation to make its buds grow well. However, the temperature of Toona sinensis seedlings should be controlled at about 65438 07℃ at night, which can accelerate its germination time. When Toona sinensis seedlings germinate, their temperature must be controlled at about 25 degrees. At this time, according to the living conditions at that time, some heat preservation things can be added to the seedlings germinated in spring, which is beneficial to improve the germination rate of Toona sinensis seedlings. Check the fruit bag regularly, and take timely measures if the paper bag is damaged or the bag mouth is loose.
How to improve the survival rate of fruit tree planting is the key link to ensure the early high yield of fruit trees. Long-term production practice shows that mastering planting methods and strictly controlling planting pits, seedling raising, planting and post-planting management can significantly improve the survival rate. If the soil subsides naturally, such as planting in autumn in rainy season, the survival, growth and development of seedlings can be avoided from being affected by soil subsidence after planting. When releasing seedlings, pay attention to that the grafted part faces north (because the tree has phototropism, the distribution of the crown can be adjusted when the grafted part faces north, and the northwest wind blows more in the north, which can prevent the wind from folding), and straighten the body, then fill the soil, and fill it from all sides to the middle when filling the soil, and keep it uniform.
