How to plant pear trees to make pear trees grow evenly?

Like other trees, pear trees often bear more fruit in the first year and less in the next year. The reasons for this uneven annual yield are, first, improper regulation and control of fertilizer and water, resulting in imbalance of soil nutrient supply, or partial application of nitrogen fertilizer causing prosperity; second, too much fruit in the big year, weakening the formation of flower buds in the next year; third, blooming too luxuriantly in the new year, producing a large amount of gibberellin, which inhibited the differentiation of flower buds in the following year; fourth, freezing some flower buds to death; fifth, drought and waterlogging caused a large number of flower buds and young fruits to fall off.

In order to prevent the emergence of small years of pear trees and promote the balanced growth, high and stable yield of pear trees, we should pay attention to the following points in the preventive measures.

The root development of pear trees had two peaks, one from late May to the first and middle of June, and the second from September to November. In order to make the root system developed and strong, it must be combined with deep turning rhizosphere soil, sufficient organic fertilizer, combined with phosphorus and potassium fertilizer, and the depth of turning soil should reach 50 cm. Only when the soil is fat enough, can we cultivate and protect the roots.

After the new leaves were unfolded in spring, nitrogen fertilizer was mainly applied, multi-component compound fertilizer was applied in June, insect control and disease control was carried out from July to August, and urea and potassium dihydrogen phosphate were sprayed 4 times. In this way, it can not only ensure the balanced supply of nutrients, but also improve the level of flower bud differentiation.

As a result, the tree potential should remain strong, the whole branch group should be younger, the middle and branchlet groups account for 90%, the medium and short branches are strong, and the new shoots on the periphery of the crown are 30cm long and 40cm long. When you blossom and bear fruit, you should first remove the weak buds and flowers. After 30 days of falling flowers, the general fruit will no longer fall off, and at this time, diseases, insect pests, deformed fruits and stagnant fruits should be removed to maintain the average yield of pear trees all the year round.

During the growth period, it is necessary to keep sprout water, post-anthesis water, fruit-promoting water, autumn and winter water in the soil of the pear orchard, and the lack of water should resist drought by stages. At the same time, large drainage ditches should be dug around the pear orchard to prevent waterlogging. In the prevention and control of diseases and insect pests, mainly prevent pear rust, scab, red spider, pear wood lice, leaf moth, pear heart borer and so on.
