1. Clear the garden

After the fruit is harvested, it is necessary to clean up the residual withered branches and leaves, rotten fruit, and weeds in time, burn them or bury them deeply, and avoid overwintering hideouts for germs and pests, so as to avoid the spread of diseases and insect pests in the coming year and reduce the base number of diseases and insect pests.

2. Turn over the ground

There are many pests in the orchard soil in winter, such as pear heart borer, pear weevil, pear gall midge, etc., so after clearing the garden, the soil in the tree plate should be turned over again, 25-35 cm deep, and the whole orchard should be ploughed, so that the overwintering pests can be frozen out of the ground or eaten by birds, or they can be turned into the depths of the ground to suffocate them. This can not only improve the shape of the soil, but also help to eliminate overwintering pests, but pay attention to less root damage. The garden soil 1 × 1 meter away from the canopy should be turned 35-50 cm as deep as possible. Freeze the pests in the soil to death, prevent the soil from hardening, and disinfect the soil with lime.

After a year of growth, fruit trees are easy to cause tree shape disorder. In order to form a good crown structure and achieve high quality and stable yield, shaping and pruning can be carried out from December to January in winter. The main purpose is to make the crown branches evenly distributed, grow evenly, do not cover each other, and help to form a tree structure of early knot, high yield and stable yield.

After a year of growth and flowering and fruiting, the nutrients of the fruit trees are consumed greatly, so it is necessary to replenish the nutrients in time. Generally, the orchards are irrigated from mid-December to early January. In the full fruit stage, each plant is applied an average of 25kg of fecal water, 5-7.5kg of bean cake and 2.5kg of calcium superphosphate, while the primary fruit trees are calculated according to this ratio of 2/3.
