Are you okay after picking an apple? The next management is more important!
"Feed" in time after harvesting
Be sure to "feed" as soon as possible after picking the fruit. The earlier the effect, the better. It will end at the latest in early November. Not only should the time be early, but also the amount should be sufficient. According to the reasonable situation of the tree situation, pay attention to the principles of "early, full, full, deep, uniform, cooked, clever, and thorough" when "feeding". The depth of the fertilization pit is 35 ~ 40 cm (concentrated distribution layer of the root system). Although this depth will damage some roots, some of the damaged roots in this period are conducive to the regeneration of the later root system and generate new roots. When fertilizing, we must pay attention to applying fertilizer Stir well with the soil to avoid root burning.
Note: If homemade fertilizer is used for fertilization, it must be fully decomposed. Whether it is pig dung, cow dung, sheep dung, chicken dung, etc., it has high salt content, heavy metal content, harmful substances and worm eggs. Insufficient, not only will cause great damage to the tree, the fruit will not reach the standard of organic fruit.
This is to increase the accumulation of photosynthetic products, reduce inefficient consumption, and increase effective nutrition storage. At the same time, it is beneficial to directly visualize the dense and dense distribution of branches and reduce the pressure of winter shear in the late stage. For sawing mouth, apply healing agent in time to prevent frost and anti-corrosion to promote healing; for dense and disturbing tree-shaped long branches and thick branches, cut and enhance Ventilation and light transmission, create good conditions for the accumulation of photosynthetic products.
After harvesting the fruit, the garden should be dug in time and fertilized in the fall to bury the diseased fruit, diseased skin, diseased branches, weeds, fallen leaves, etc. in the fertilizer pit, turn it into a treasure, or take it out of the garden and burn it.
After clearing the garden, spray the medicine in time to pick the fruit. After clearing the garden, spray the whole garden with sterilization, pesticides and nutrient solution in a timely manner to extend the leaf function and increase the accumulation of photosynthetic products, which can effectively reduce the wintering base of pests and diseases in the orchard, and kill the Extinction effect.
Fungicide: Tridemorpholine or triazole 2000 times (Omesec or Tebuconazole).
Insecticides: 800 times permethrin or peach spirit (Kung Fu or Cho Chun).
Nutrient solution: 1: 100 times urea or 1: 400 times Ouda nail fluid.
Not only "to eat" but "to dress well"
In winter, we should pay attention to wearing "warm clothes" while "satisfying" the fruit tree. ①Buried mounds at the trunk of the tree. ② The trunk is painted white, which not only keeps you warm but also prevents diseases. ③ Pour in frozen water after winter. ④ The whole tree is sprayed with 200 times of new high-fat film or 200 times of Lizhanjing, which has good antifreeze effect. Before the advent of severe cold, spray antifreeze 1000 times in time, which has a good cold protection effect. ⑤ Cover the grass with a thickness of 15-20cm (straw, peanut shell, etc.) under the canopy, keep warm and moisturize.
