How to manage pear trees in winter? Detailed explanation of the latest technical key points

Winter management of pear trees is extremely important and is a key measure for achieving high returns; it is also extremely important for addressing the “alternate bearing” of pear trees and for improving yield and quality. So how should pear trees be managed in winter? Follow the editor and take a look.

1. Orchard cleanup

After the fruit is harvested, promptly clean up the remaining dead branches, fallen leaves, rotten fruit and weeds, and burn them in a centralized manner or bury them deeply. Never leave overwintering hiding places for pathogens and insect pests, so as to avoid an outbreak of diseases and pests the following year and reduce the base number of diseases and pests.

2. Plowing

In winter, there are relatively many insect pests in the orchard soil, such as the pear fruit borer, pear weevil, pear gall midge, etc. Therefore, after orchard cleanup, the soil within the tree plate should be turned over once, to a depth of 25-35 cm, and the whole orchard should be plowed, so that overwintering pests are turned out of the ground to freeze to death or be eaten by birds, or are turned deep underground to be suffocated. This can both improve soil structure and help eliminate overwintering pests, but care should be taken to damage the roots as little as possible. For orchard soil beyond 1×1 m outside the canopy, plow as deeply as possible to 35-50 cm. This freezes pests in the soil to death and also prevents soil compaction, while scattering lime to disinfect.

3. Training and pruning

After a year of growth, fruit trees very easily become structurally disordered. In order to form a good canopy structure and achieve high quality and stable yield, training and pruning can be carried out in winter from December to January. The main purpose is to make the branches in the canopy evenly distributed, with balanced growth, without shading or intertwining with each other, which helps form a tree structure with early fruiting and high and stable yield.

4. Fertilization

After a year of growth, flowering and fruiting, the tree's nutrients are heavily consumed, so nutrients need to be supplemented in time. Generally, irrigation and fertilization are carried out from mid-December to early January. For trees in full fruiting stage, apply an average of 25 kg of manure water, 5-7.5 kg of soybean cake and 2.5-5 kg of superphosphate per tree; for trees just beginning to bear fruit, calculate at two-thirds of this ratio. The application method is to open a ring-shaped ditch 35-50 cm deep under the canopy drip line, apply the fertilizer liquid into it, and then cover with soil.
