The roots of fruit trees appear to be rotten, but they affect the yield and quality. Severe ones lead to the death of the trees and cause losses to the fruit farmers. Therefore, attention must be paid to management to prevent this phenomenon from occurring. First, long-term fertilizer leader, fruit trees first hurts Long-term application of diammonium, urea, potassium sulfate, compound fertilizers, compound fertilizers and other chemical fertilizers have destroyed the soil and caused many catastrophic problems for fruit trees. For example, organic matter is seriously deficient, resulting in soil compaction, poor ventilation, severe acidification of the soil, vigor and vigor, severe rot and serious physiological disease, and declining fruit quality. Second, a large number of unfermented farmyard manure is used to cause rot A large number of unfermented and degraded people, livestock, and poultry manure are directly applied to the orchard soil. The large number of pathogens, pests, and salt carried by them will cause serious damage to the root system. In severe cases, it will cause rot and dead trees. In order to save labor and labor, it is common to use acupuncture and furrows, and dig furrows (holes) that are small and small. It is also a common phenomenon to fill the pits with fertilizers, cover the soil, and burn the roots. The root distribution of apples is mainly within the range of 20-80 cm below the surface of the ground, and the concentrated distribution layer is approximately 40 cm below the surface. Farmers are saving labor and energy, digging trenches to fertilize more and more shallow, and even worse, they spread fertilizer on the ground to wait for rain. The roots go along with the fertility. Year after year, the roots of the fruit trees are introduced to the surface. They are neither drought nor impatient, and are not conducive to the absorption and utilization of fertilizers. The serious consequences of the root-displacement of the earth's surface are that the resistance of the fruit tree deteriorates. When drought, chilling, and freezing occur, dead trees and dead trees are easily caused. Third, long-term abandoned soil management, intensified soil consolidation The orchards will not be fully planed for a long time. Spring and summer grass will all rely on herbicides, which will only destroy weeds, and will not clear the aeration of the soil. As a result, the living soil layer is in a state of serious consolidation for a long period of time, and the roots of the fruit trees are led to the surface layer, which is neither drought nor resistance. After the rain, the soil was poorly ventilated, and the roots suffocated and a lot of fallen leaves. Fourth, the tree stores a serious shortage of nutrients, is the main cause of rot disease Orchard households that normally strengthen management, spraying pesticides, applying fertilizer in the summer, applying base fertilizer in the autumn, and all management are in place to maintain adequate storage of nutrients in the trees, few rot diseases in winter and spring, high fruit setting rate, and rapid young fruit enlargement. The new shoots are thick, and the leaves are thick and shiny. The orchard households who gave up management did not top-up fertilizer in the summer and did not use basal fertilizer in the autumn. The tree's nutrition was seriously deficient, causing rot disease to flood and causing many fruit trees to be shaved off. The surviving part of the fruit tree, full of tree trunks, shrunk to the tree, sitting on a small number of small apples, yellow leaves, as small as artichoke leaves. It can be seen that the use of basal fertilisers in the autumn and adequate storage of nutrients in the winter are the key to maintaining the robustness of the tree and resisting the infection of rot. It is also the basis for guaranteeing the high yield and quality of the fruit in the following year. Therefore, many experts have called for: Autumn Schiff base fertilizer is "gold", Winter Schiff base fertilizer is "silver", and Spring Schiff base fertilizer is "Broken Iron and Iron."
