Management techniques of Apple in Winter

Now it has gradually entered winter, and apples are also fruits that many people like to eat in winter. However, for many fruit growers, they do not like winter very much, because the winter temperature is low, and the management of apple trees will naturally be more difficult. And there will also be due to poor management, resulting in fruit trees appear freeze injury and so on. How to manage apple trees in winter? Today, Xiaobian brought the winter management technology of apple trees. Let's take a look at it together!

1. Clean up the orchard

Apples are usually harvested in autumn, so garden cleaning should be done after harvest. The diseased branches and fruits on the fruit trees should be cut off in time, and the weeds, sick 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 pathogens and various eggs will lurk in these media for winter, wait until the spring temperature rises to wake up infected fruit trees. However, the fallen leaves of fruit trees can be buried deep in the orchard soil according to specific conditions to increase the organic fertilizer in the soil, but the depth of deep burial cannot be less than 60 cm.

2. Apply enough basal fertilizer

Applying enough basal fertilizer is one of the basic measures to help apple trees overwinter. Applying enough basal fertilizer not only helps fruit trees overwinter successfully, but also makes spring shoots and buds grow stronger in the coming year. When applying base fertilizer, the amount should be controlled according to tree vigor, soil fertility and harvest amount. Together with tillage, it can ensure uniform fertilization of soil, improve soil permeability, and improve root respiration and nutrient absorption. Base fertilizer should use fully decomposed farm manure, and the base fertilizer should not be applied to a depth of less than 40 cm.

3. Overwinter watering

Apple trees enter dormancy in winter. Dormancy fruit trees do not absorb nutrients and water, and nutrients from fruit trees gradually flow to the roots. Therefore, before the fruit trees enter the winter dormancy period, it is necessary to irrigate the winter water in time, which can not only ensure the water demand of the fruit trees, but also promote the decomposition of the 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 can promote the next spring, fruit flower bud differentiation. Therefore, it is necessary to ensure that the soil has sufficient water content during winter and improve the flowering rate of the second year.

4. Fruit tree pruning

Before winter, we should do a good job of pruning fruit trees, adjust the structure of apple trees, and cut off excessive, dense, overlapping branches in time. Enhancing tree permeability is beneficial to improve tree nutrient accumulation and promote flower bud differentiation. However, when pruning, it is also necessary to change the pruning method according to the age of the tree. For example, it is not recommended to cut off the branches of young trees. The method of cultivating the skeleton structure of the tree can be used to regulate the tree vigor. Adult can be appropriate to cut off branches, so that nutrition concentration, cut off branches to protect the wound, prevent infection caused by diseases and insect pests.

The above is a brief introduction to Apple's winter management technology, Apple's winter management is very important. The quality of management directly determines the flowering rate of the coming year and cannot guarantee the yield. Therefore, we must do a good job in winter management of apples to ensure efficient planting of apples. Otherwise, it will cause fruit trees to freeze and fail to grow and develop when it is serious.
