Five points before the equinox results tree management mistakes
1, do not engage in autumn trim. Many fruit growers will allow leggy and developmental branches to grow after the fruit is picked. In fact, this is a misunderstanding. At this time, the autumn season, light, heat and other atmospheric conditions conducive to photosynthesis of fruit trees. Through the short cut, thinning, retracting branches, pressing down the branches, "open skylight" and other technical measures to create conditions for the group to ventilate light, which is of great significance for enriching flower buds and reserve nutrition.
2, no base fertilizer. According to the conventional management, after the early-maturing varieties of fruit trees are harvested, the base fertilizer should be applied in autumn. These fertilizers mainly consist of high-quality organic fertilizers such as high-quality ring fertilizer, soil miscellaneous fertilizer, and plant straw, and are mixed with compound fertilizer. After fertilization combined with deep garden soil, timely watering in order to play a fertilizer effect. At this time, the conditions of temperature and soil moisture are appropriate, which is conducive to promoting the healing of new roots and wounds, as well as the absorption and utilization of fertilizer and water by roots. Once the opportunity is missed, there will be no waste of light, heat, water and fertilizer resources.
3, turned to fear the root cause. Whether the fruit tree can grow normally or not depends mainly on whether the root system has a good ecological environment. Such as loose soil ventilation, fertilizer and water conditions are appropriate, fruit trees will naturally grow. For the moment, many orchards have had their soil compacted and their roots are not functioning properly, resulting in poor tree growth. In particular, in some black clay orchards, the annual application of chemical fertilizers does not apply fertilizer, which intensifies the degree of soil compaction; there are also many orchards who seldom give the orchards the opportunity to loosen the soil, and mistakenly believe that the land will be damaged, year after year, soil More and more hardened.
4, do not spray after fruit picking. Some people think that it is an extra measure to spray medicine after harvesting fruit. After harvesting the fruits in autumn, the tree has a natural rest period. The people are commonly called "breaking trees." At this time spraying is mainly disease prevention and pest control, protection of the leaves, in order to use the light and heat conditions in autumn to extend the effective period of the leaves, increase the utilization of photosynthetic, increase nutrient accumulation, reduce the source of overwintering and disease. The main targets for prevention and treatment are pear black spot disease, apple brown spot, leaf roller moth, and gold leaf moth.
5, do not pay attention to pull branches, top branches and opening angle. During the whole growing season, the fruit volume gradually enlarges, the tree load increases, and the angles of the main branch and the auxiliary branch increase accordingly, so that the ventilation and light transmission conditions can be improved. During the period from fruit ripening to harvesting, the angle of the tree reaches the best state. Within a period of time after the fruit is harvested, the angle of the tree has a relatively stable period. When the angle of the plant can not be recovered in the production, the top and the bottom are pulled. Technical measures such as bracing and bracing are fixed.
