So, what are the planting techniques of grapefruit? How to plant high yield?
1. What are the planting techniques of grapefruit?
1. Seed propagation and seedling raising
Collect ripe fruits, then peel off the skin to collect seeds and store them in a cool place.
When sowing, choose a place with water source and fertile and loose soil to build a nursery, dig deep and then apply base fertilizer.
Step 2: Stratification
Air stratification can be used. For layering method, 3-4-year-old upright branches in the middle and upper part of the crown of excellent mother trees should be selected, the cross-sectional trunk diameter should be more than 1/2, and then they should be split vertically upwards, the length of which is slightly shorter than layering (bamboo slips or plastic paint film), or peeled into rings, and then placed on a pressure basin filled with loose broken soil and kept moist.
The sowing date will vary according to different regions, such as Guangxi and Fujian. Due to the drought in autumn and winter and strong sunshine, it can be advanced appropriately.
Step 3: Planting
Grapefruit is planted in the open space in front of and behind the house. Choose shady slope or middle shady slope with deep soil for pumping. When cutting the heel in autumn, plant it after one year. Planting holes with a width of 1m and a depth of 1.5m were used, and each hole was filled with base fertilizer, 59 kg of organic fertilizer and 0.5 ~ 1 kg of calcium superphosphate.
The planting time is generally from February to March in spring or autumn. When planting, the root neck of the plant should be flush with the ground, and the root system should not directly contact with the thick base fertilizer. The planting row spacing is 7x5m or 6x5m, and about 22 plants are planted per mu19.
Second, how to grow grapefruit with high yield?
1. Planting and land selection
After understanding the planting technology of grapefruit, how to plant high yield? Then the preparation before planting is essential. Before planting, choose a place with fertile soil and sufficient water. If the land is not selected well, the yield of grapefruit will be greatly affected.
2. Planting spacing
Many growers often feel lucky when planting grapefruit saplings, because everyone thinks that planting more grapefruit on the same size land will yield more, but this is very wrong, because unreasonable planting spacing will affect the photosynthesis of grapefruit leaves, thus affecting the fruit quality and yield of grapefruit.
What are the planting techniques of grapefruit? How to plant high yield? Seeing this, I think everyone has a certain understanding.
Some problems that we may encounter in the process of grapefruit planting, such as small details in the process of planting and later cultivation management, can not be ignored. We should all take it seriously and understand the importance of being down-to-earth, so as to gain more.
