Misunderstanding one, do not engage in autumn pruning
After harvesting fruit, many fruit growers are allowed to grow long branches and development branches. In fact, this is a misunderstanding. At this time, through short cuts, thinning branches, retracting branches, lowering branches, and "opening the skylight" and other technical measures, creating conditions for group ventilation and light transmission, which is of great significance for enriching flower buds and stocking nutrients.
Misunderstanding 2, no application of 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, it will cause waste of light, heat, water and fertilizer resources.
Misunderstanding 3, 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 without the application of soil and fertilizer, have intensified 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, The soil is getting more and more knotted.
Misunderstanding 4, 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 is harvested, the tree has a natural rest stage, and the common people are commonly called “resting treesâ€. At this time, the spraying is mainly to prevent disease and insects, protect the leaves, in order to utilize light and heat conditions, extend the effective period of the leaves, increase the utilization rate of photosynthesis, increase nutrient accumulation, and reduce the source of the overwintering insects and diseases. The main control objects are pear black spot disease, apple brown spot disease, small leaf roller moth, and golden fine moth.
Misunderstanding 5, do not pay attention to pull branches, top branches and opening angles
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.
