The latest course of Apple Winter Management techniques

Now it is gradually entering winter, and apple is a fruit that many people like to eat very much in winter. But for many fruit growers, they do not like winter very much, because of the low temperature in winter, the management of apple trees will naturally be more difficult. And it will also occur due to poor management, resulting in frost injury of fruit trees and so on. So how to manage apple trees in winter? Today, the editor has brought the winter management technology of apple trees. Let's take a look at it.

1. Clean up the orchard

Apples are usually harvested in autumn, so do a good job of clearing the garden after harvest. The diseased branches and fruits on the fruit trees should be cut off in time, and the weeds, diseased branches and rotten fruits on the ground should also be cleaned up in time and taken out of the orchard for centralized treatment. Because many disease germs and a variety of eggs will lurk in these media to survive the winter and wake up infected fruit trees when the temperature rises in spring. However, the fallen leaves of fruit trees can be buried deep in the orchard soil according to specific conditions, increasing the organic fertilizer in the soil, but the depth should not be less than 60 cm.

2. Apply sufficient base fertilizer

Applying sufficient basal fertilizer is one of the basic measures to help apple trees survive the winter. applying sufficient basal fertilizer can not only help fruit trees survive the winter successfully, but also make the growth of spring shoots and buds more robust in the coming year. When applying base fertilizer, the amount should be controlled according to various factors such as tree potential, soil fertility and harvest. Carried out together with ploughing, it can not only ensure that the soil is fertilized evenly, but also improve soil permeability and root respiration and nutrient absorption. The base fertilizer should be fully mature farm manure, and the depth of the base fertilizer should not be less than 40 cm.

3. Watering overwintering water

Apple trees will enter the dormant period in winter, dormant fruit trees will not absorb nutrition and water, and the nutrients of fruit trees will gradually flow to the roots. Therefore, before the fruit trees enter the winter dormancy period, it is necessary to irrigate the overwintering water in time, which can not only ensure the water demand of fruit trees, but also promote the decomposition of base fertilizer. It is beneficial to the formation of new roots, improve the nutrient absorption of roots, and strengthen the assimilation of nutrients in fruit trees. And it can promote the flower bud differentiation of fruit trees in the following spring. Therefore, when overwintering, it is necessary to ensure that the soil has sufficient water content and improve the flowering and fruiting rate of the second year.

4. Pruning fruit trees

Before the beginning of winter, it is necessary to do a good job in pruning fruit trees, adjust the structure of apple trees, and cut off branches such as overgrowth, overdensity and overlap in time. Enhancing the permeability of the tree is beneficial to improve the nutrient accumulation of the tree and promote the flower bud differentiation of fruit trees. However, when pruning, the pruning method should also be changed according to the tree age. for example, young trees are not recommended to cut off the branches, and the tree potential can be regulated by cultivating the skeleton structure of the tree. The adult genus can properly truncate the branches and concentrate the nutrition. After cutting off the branches, it is necessary to protect the wound and prevent diseases and insect pests caused by infected bacteria.

The above is the editor's brief introduction to the winter management technology of Apple, which is very important. The quality of management directly determines the rate of blossom and fruit in the coming year, and there is no guarantee of output. Therefore, we must do a good job in the winter management of apples in order to ensure the efficient cultivation of apples. Otherwise, when it is serious, it will lead to frost injury of fruit trees, unable to grow and develop. That's all for today's introduction. This article is for reference only.
