What problems should you pay attention to pear fruit

The fruit thinning of pears is one of the key agricultural operations in pear production. Through fruit thinning, the amount of fruit set can be controlled and the pear tree can be reasonably burdened. In the case of fruiting pears, the sooner the fruit shrubs are, the better it can reduce the consumption of stored nutrients.

When pear fruit thinning should pay attention to what problems?

When large and small fruits are clearly sorted, fruit thinning should begin. When fruit thinning should be based on species, tree vigor and flowering climate, high fruiting rate should be carried out within 10 to 15 days after flowering, and species with longer physiological fruiting period are falling. After 20 days, the fruit can be thinned, and it is better to spend too much time, higher fruiting rate, weaker tree vigor, and young trees and busy trees with less fruit.

Saplings In order to ensure good growth of the branches and to expand the canopy, it is imperative to remove the pear fruit that has grown on the branches. When fruit thinning is carried out, pests and fruits, traumatic fruit, malformed fruit, young fruit with dull skin color and dull skin should be removed, and young fruit with robust development should be kept. Inflorescences are numbered from top to bottom. It is best to keep the third or fourth fruit in the fruit position. In principle, leave 1 fruit per fruit, and each fruit should have 25 to 30 leaves.

At the same time, the thinning fruit should be chosen to retain the fruit position in favor of the bagging operation. After fruit thinning (30-45 days in Shenghua), smearing the plant growth regulator on the upper part of the stalk can increase the size of the pear fruit, increase the morning market, and increase the sweetness. For example, if the “pear and fruit” is applied, the temperature should be below 30°C. Apply 3800-4500 fruits per 50g, and apply 1/3 pear fruit to each tree. The whole tree has no effect.
