Four key points of Pear Orchard Management in Winter

Pears are the best-selling fruit in winter, and it is also the season for pear harvest after winter. Pear is also a perennial fruit tree, most of the nutrients in the pear tree will be separated from the fruit after harvest, resulting in a very weak state of the pear tree. Therefore, the management of pear orchard in winter is very important. So how to manage pear trees in winter? The following editor brings you the key points of the management of pear orchards in winter. Let's have a look!

1. Ploughing and weeding

Ploughing and weeding is very important for the growth of pear trees in winter. As I just said, pear trees have very little nutrition in winter. If there is no timely weeding, weeds will rob the pear tree of nutrition, resulting in the pear tree nutrition absorption is blocked, unable to restore growth, very easy to produce freezing injury. Therefore, we have to combine with fertilization in winter, remove the weeds and bury them in the soil as green manure. Then turn the soil deeply and pay attention to the position when ploughing to determine the depth of intertillage. For example, it should not be too deep under the canopy, and the depth between rows should be about 25 cm, destroying the overwintering place of germs and insect eggs.

2. Timely fertilization

Fertilization is an important measure to restore the growth of pear trees as soon as possible. pear trees lack nutrition, their growth becomes weaker, and the ability of cold resistance and disease resistance will be greatly reduced. Therefore, we should replenish the nutrition lost due to fruit picking in time. Turn deeply before the beginning of winter, dig a good fertilizer ditch, and then apply enough fertilizer to overwinter. Promote the nutrient absorption of pear trees and resume the rising trend, and the amount of fertilizer applied at this time accounts for about 30% of the total fertilizer in the whole year. Be sure to pay attention to the amount, not too much too little, too much is easy to cause fertilizer damage, too little nutrition leads to pear freeze damage, fertilizer to mature farm manure.

3. Pruning

The purpose of pruning and pruning is to avoid too many branches of pear trees, consume too much nutrition on the branches and affect the growth of the trunk. When pruning, we should pay attention to different pruning methods for fruit trees of different ages. For example, for pear trees growing within two years, the work of hanging branches and supporting branches should be carried out in about 3 new branches in summer. Ensure that the branches have an angle of about 65 cm to prevent overgrowth and promote the dwarfing of the crown. Then the methods of thinning and cutting were used for adult pear trees to improve the permeability of crown and enhance the fruiting ability of branches.

4. Pest control

The prevention and control of diseases and insect pests need to be paid attention to throughout the year. In winter, we should concentrate on removing fallen leaves and branches, falling flowers and fruits, and pruning weeds, take them out of the orchard for burning treatment, and then pay attention to scraping the warped bark of fruit trees to destroy the overwintering places of diseases and insect pests. And the straw can be placed around the pear tree to lure pests to the straw for the winter and then burn it in the spring of the following year. Then the trunk of the pear tree was whitened, and after the fallen leaves, the pear orchard was comprehensively and uniformly sprayed with Baumedu stone sulfur mixture and other chemicals, and the drug residue was used to whiten the trunk.

The above is a brief introduction of the main points of winter pear orchard management, the winter management of pear orchard is very important. If the management is improper, it will affect the flowering and fruiting of the following year, and the rate of flowering and fruiting of pear trees will be very low in the future, so we must pay more attention to it.
