Apple orchard winter management details

Do not rush to paint the trunk white after careful inspection of fallen leaves after leafing. Firstly, conduct thorough and detailed inspections on the fruit trees. The fruit trees must be checked for nicks, scars, and large branches. Carefully and thoroughly remove the lesions and dead skin on the trees. After the application of the drug, the entire tree is sprayed with an anti-scavenging agent such as lime sulfur to protect the tree. This is the key to prevention and control of rot disease in the coming year.

The pruning tool should pay attention to disinfecting the winter pruning. First cut the healthy tree, then cut the tree with serious rot and viruses, and pay attention to the disinfection of the pruning tools. Many kinds of diseases can be spread through pruning tools, and they must be noticed.

Clear gardens should be thoroughly cleaned after the end of winter pruning. The remaining leaves on the trees, the debris on the ground, debris, fallen leaves, and broken branches should be cleared out of the orchard and incinerated. After the garden is cleared, the whole tree is sprayed with limestone. The mixture is completely tree-sealed.

It is important that the fruit trees be painted white and frost-proof winter fruit trees be whitened. Many farmers think that whitening has a pest-proof effect. In fact, the purpose of whitening is to prevent freezing. In the early spring from the end of the natural dormancy period of fruit trees, the trunk and large branches are exposed to direct sunlight, and the temperature rises, so that the tree's sunny side cells are active. When the temperature drops rapidly, the fruit trees are vulnerable to freezing injury, especially young. Trees, weak trees, and leggy trees. The whitening of the fruit trees can make the trunk reflect the sunlight, reduce the temperature difference between day and night of the trunk, prevent the occurrence of frost damage, and reduce the occurrence of fruit rot in the spring. The correct method of whitening is to carefully scrape off the lesions, dead skin, and disinfect the fruit trees before applying white. All the stems and the sunny side of the main branch should be painted.
