How to do winter management of apple trees? Latest technical method tutorial
Now it has gradually entered winter, and apples are also a fruit that many people very much like to eat in winter. But for many fruit growers, winter is not very welcome, because when the temperature is low in winter, the management work of apple trees will naturally be more difficult. And there will also be situations such as frost damage to the fruit trees due to poor management. So how should apple trees be managed in winter? Today the editor brings the winter management techniques for apple trees. Let's take a look below!
1. Clean the orchard
Apples usually mature and are harvested in autumn, so after harvesting, the orchard cleaning work must be done well. Diseased branches and diseased fruits on the fruit trees should be pruned off in time, and weeds on the ground, diseased and residual branches and rotten fruits should also be cleaned up in time and taken out of the orchard for centralized treatment. This is because the pathogens of many diseases and various insect eggs lurk in these media to overwinter, and when the temperature rises in spring they wake up and infect the fruit trees. However, the fallen leaves of the fruit trees can, according to specific circumstances, be buried deep in the orchard soil to increase the organic fertilizer in the soil, but the depth of deep burial must not be less than 60 cm.
2. Apply sufficient base fertilizer
Applying sufficient base fertilizer is one of the basic measures to help apple trees overwinter. Applying sufficient base fertilizer is not only conducive to helping the fruit trees overwinter successfully, but can also make the spring shoots and flower buds of the next year grow more robustly. When applying base fertilizer, the amount should be controlled according to various factors such as tree vigor, soil fertility and harvest amount. Carrying it out together with plowing work can ensure that the soil receives fertilizer evenly, and can also improve soil permeability and enhance root respiration and nutrient absorption. The base fertilizer should use fully decomposed farmyard manure, and the depth of base fertilizer application must not be less than 40 cm.
3. Water with overwintering water
Apple trees enter dormancy in winter. Fruit trees in the dormant period do not absorb nutrients and water, and the nutrients of the fruit trees gradually flow to the roots. Therefore, before the fruit trees enter the winter dormant period, overwintering water should be watered in time, which can not only ensure the fruit trees' demand for water, but also promote the decomposition of base fertilizer. It is conducive to the formation of new roots at the root and improves the nutrient absorption of the root system, strengthening the assimilation of nutrients in the fruit trees. And it can promote the flower bud differentiation of the fruit trees in the spring of the second year. Therefore, during overwintering, the soil must be ensured to have sufficient water content to improve the flowering and fruiting rate of the second year.
4. Fruit tree pruning
Before the beginning of winter, the pruning work of the fruit trees must be done well, adjusting the structure of the apple trees, and pruning off excessive vegetative branches, overly dense branches and overlapping branches in time. This enhances the permeability of the tree body, which is conducive to improving the nutrient accumulation of the tree body and promoting flower bud differentiation of the fruit trees. However, when pruning, the pruning method should also be changed according to tree age. For example, for young trees it is not recommended to prune off branches; the method of cultivating the tree skeleton structure can be used to regulate tree vigor. Adult trees can appropriately cut back branches to concentrate nutrients. After pruning branches, the wounds must be protected to prevent infection by pathogens and the occurrence of pests and diseases.
The above is the editor's brief introduction to the winter management techniques for apples. The winter management of apples is very important. The quality of management directly determines the flowering and fruiting rate of the next year, and the yield cannot be guaranteed. Therefore, the winter management of apples must be done well to ensure efficient apple cultivation. Otherwise, in severe cases, it will cause frost damage to the fruit trees, and they will be unable to grow and develop. That is all for today's introduction. This article is for reference only.
