The consequences of the autumn tree five misunderstandings Do not engage in autumn trimming Many fruit farmers are allowed to grow long branches and development branches after fruit picking. In fact, this is a misunderstanding. At this time, the autumn is high, and the environmental conditions such as light and heat are favorable for photosynthesis of fruit trees. It can be used to create conditions for group ventilation and light transmission through short cuts, thinning branches, retracting branches, lowering branches, and “opening the skylightâ€. This is of great significance for enriching flower buds and stocking nutrients. No base fertilizer According to the conventional management, the early-maturing varieties in the fruit trees should be harvested in time for the autumn-based base fertilizer. These fertilizers are mainly composed of high-quality organic fertilizers such as fertilized fertilizer, soil-fertilizer and plant straw, and mixed with compound fertilizer. After fertilization, combined with deep turning of the garden soil, timely watering can be used to exert fertilizer efficiency. At this time, the temperature and soil temperature and humidity conditions are suitable, which is conducive to the promotion of new roots and wound healing, as well as the absorption and utilization of fertilizer by roots. Once you miss the opportunity, there will be no waste of light, heat, water and fertilizer resources. Turning the ground and fearing the roots Whether the fruit tree can grow normally or not depends mainly on whether the root system has a good ecological environment. If the soil is loose and airy, the fertilizer and water conditions are suitable, and the fruit trees will naturally grow normally. For the time being, many orchards have soil compaction and roots are unable to move normally, resulting in poor tree development. In particular, some black clay orchards, perennial application of chemical fertilizers do not apply soil and fertilizer, which exacerbates the degree of soil compaction; there are still many orchard owners who rarely turn the orchards to loosen the soil, mistakenly believe that turning the ground will hurt the roots, year after year, soil More and more knotted. Do not spray after picking fruit Some people think that it is more than one thing to spray the medicine after picking the fruit. After the fruit harvest in autumn, the tree has a natural rest stage, and the common people are commonly known as “resting treesâ€. At this time, the spraying is mainly to prevent disease and insects, to protect the leaves, in order to utilize the light and heat conditions in autumn, to extend the effective period of the leaves, to improve the photosynthesis utilization rate and increase the nutrient accumulation. Such as spraying "guard tree general", can reduce the wintering insect source, the source of disease, while at the same time can prevent heat and freeze, prevent pests and diseases, the main control objects are pear black spot disease, apple brown spot disease, small leaf roller moth, gold fine moth. Do not pay attention to pull branches, top branches open angle During the whole growing season, the fruit volume gradually expanded, the tree body load increased, and the angles of the main branches and auxiliary branches increased, which improved the ventilation and light transmission conditions. During the period from fruit ripening to harvesting, the angle of the tree body is at its best. During the period after fruit harvesting, the angle of the tree body has a relatively stable period. When the angle of the plant can be recovered, the top, pull, Technical measures such as support and shackles are fixed.
