First, timely supplementation of fertilizer water
Fruit tree flowering results in the consumption of a large amount of nutrients, which will make the tree extremely weak. After harvesting the fruit, it should promptly supplement the nitrogen, phosphorus and potassium quick-acting fertilizers, increase the use of bacterial fertilizer and organic fertilizer, and also properly hydrate the water.
At this time, the soil temperature is high. It is recommended to apply sufficient microbial fertilizer. The soil beneficial microorganisms can rapidly multiply in the soil, accelerate the decomposition and transformation rate of nutrients, promote root absorption, and quickly replenish the nutrients of the tree for the coming year. The high yields accumulate sufficient nutrients. (Note: The amount of fertilizer applied to fruit trees should be based on tree age, tree potential, and yield.)
In addition, it is recommended that after harvesting the apples, before spraying the leaves, spray 800-1200 times of liquid in every 10 days or so, and add the baby to the tree, supplement the tree nutrition, improve the leaf photosynthesis, and enhance the tree resistance. Sick ability.
Second, pest control
The tree is kept by leaves, the leaves are long, and the leaves are the processing plants for fruit trees, so it is very important to protect the leaves. After entering the rainy season, the leaf pests and diseases are high. Therefore, after the fruit picking, the leaf pests and diseases should be controlled in time, and the disease should be timely and timely according to the occurrence of diseases and insect pests to prevent the occurrence of early leaves.
At this time, the main pests and diseases are powdery mildew, rust, brown spot, anthracnose, ring disease, rot disease, heartworm, red spider and so on.
Third, timely trimming after harvest
After harvesting, it should be trimmed in time to control the growth of shoots. The pruning is mainly based on combing, retracting, topping, and strong pulling. The erect and long-lasting prosperous branches, long-term competing branches and pests are cut off, and the weak branches are properly retracted. The prosperous branches of the growing space adopt topping and twisting branches, and pull the branches at an inappropriate angle to make the orchard ventilate and light, save nutrition, reduce consumption, and promote flower bud differentiation.
