Topdressing timely after fruit picking
In order to make the apple trees survive the winter safely, maintain a good tree vigor. Therefore, if the base fertilizer is not applied in autumn or the amount of base fertilizer is insufficient in September, it will seriously affect the tree body and nutrient storage. Although it is a bit late, it is stronger than applying it after the beginning of spring. In this supplementary fertilization, the depth of 20 cm must be changed to 30 cm, and the effect will be better. Only in this way can the fruit trees be more frost-resistant and cold-resistant.
Clear the garden in time after fruit picking
Dispose of the waste in the orchard in time, such as diseased fruits, skins, diseased branches, fallen leaves, etc., and bury them or pull them out of the orchard for incineration.
The orchard was cleared immediately after picking the fruit. First, some pests and diseases were still rampant and multiplying. Second, many pests and diseases began to prepare for the winter, and even began to form "armor"; At the end of the damage, the vitality is greatly reduced, and they are all on the surface of parasitic habitats such as crops and soil, which are easier to control than after incubation or before and after "sting"; fourth, once effective control is carried out at this time, the breeding of diseases and insects will be greatly reduced, not only It can make fruit trees survive the winter smoothly, and make clearing the garden in spring a lot easier; Fifth, the spring climate in recent years is extremely unstable, and many people do not have time to take the first or second time to clean the garden, which often misses the opportunity; It is the use of clearing the orchard after fruit picking and adding calcium, magnesium and zinc fertilizers to prevent diseases and insects while increasing leaf functions. At the same time, it is to delay leaf senescence, enhance photosynthesis, increase stored nutrients, and make the tree safe through the winter; after entering the cold winter, combine winter shears to do some surface work such as cleaning fallen leaves and coating antiseptics.
The recommended plan for clearing the garden after fruit picking is: star mark 3000~5000 times (must be after fruit picking) + Longlile 1500 times + urea 3%~5%, wait a week and then use 3%~5% urea Solution, share twice.
Pruning with leaves
It was found in production practice that some orchards are densely packed with individuals and clusters, with many long strips and few branchlets, which consumes nutrients in vain. Because there is no light, it is difficult to form flowers and fruitless crowns, and there are few branches, and the power cannot be dispersed, so the trees are full every year and the yield is low.
The idea of ​​receiving more branches and yielding high yields, I can’t bear to thin branches. In addition, it’s good to watch the light during winter cutting after falling leaves, so I can’t bear to thin out the extra branches during winter cutting, let alone thinning. Well, it will be worse next year. Because fruit trees are alive and dynamic. With one long leaf and another long branch next year, the light will worsen than this year. Of course, some people do not have enough plastic pruning techniques. They are afraid of cutting the wrong branches in winter and affecting the yield, so they dare not cut the branches.
In order to solve the light problem and not to kill the extra large branches by mistake, you can "winter cutting" with leaves in early November after the fruit is picked. Because the leaves have not fallen yet, you can clearly see where the light is not good and which extra large branches need Cut it off, you can see before falling leaves, you can bring the leaves "winter cut".
