2, soil requirements, should choose to plant in deep soil layer, good irrigation and drainage conditions, loose and fertile soil. Before planting, it is necessary to dig a planting pond with a length and width of about 1m, then apply sufficient base fertilizer in the pond and cover it with a layer of fine soil.
3. Seed selection: select healthy seedlings without disease or damage for planting, then vertically put the seedlings into the planting pool, and soil and water them. Planting density must be reasonable. Generally, the plant spacing is 2m and the row spacing is 3m.
4. Reasonable water and fertilizer should be applied. Plantar fertilizer should be applied before planting, and appropriate topdressing should be applied later, especially nitrogen fertilizer can be applied in the early stage, which is conducive to promoting the growth rate of pear trees. After flowering and before flower bud differentiation, in order to supplement the nutrients needed for plant growth, compound fertilizer should be applied topdressing, while in the fruit expansion period, potash fertilizer and appropriate phosphate fertilizer can be applied topdressing, which is beneficial to promote the rapid expansion of fruit. Pear trees are drought-tolerant and can be watered once after each fertilization.
5, plastic pruning, appropriate plastic pruning, is conducive to plant growth, more flowering and fruiting, thereby increasing yield. When the seedlings grow to 70-80cm, they can be pruned and reshaped, and pruning buds is beneficial to promote branching, thus accelerating the formation of crown. When the tree is mature, it is necessary to cut off dense branches, long branches, pests and diseases, invalid branches and leave more auxiliary branches. Secondly, in order to ensure a certain fruit yield, it is necessary to increase fertilizer at flowering stage and carry out artificial pollination to ensure yield increase.
