The fruit tree cultivation in many places lacks the importance of fertilization knowledge. Due to the lack of relevant knowledge, production of fruit trees is reduced. To use organic fertilizers, promote the use of organic and inorganic fertilizers, and appropriately use chemical fertilizers according to soil fertility conditions and yield levels. The basal orchard has already been used in autumn, and there is no fertilizer or less fertilization before fruit bagging. Fertilization in autumn is recommended to fertilize before orchard germination, early drought, lack of water, supplement water before and after fertilization, is conducive to the full absorption of nutrients. Acidification of orchard soils can be achieved through the application of silicon, calcium, magnesium fertilizers and lime to improve the soil in combination with high yield and quality cultivation techniques. The fertilization of fruit trees should be based on soil characteristics, fertilizer types and varieties of fruit trees, tree age, and growth potential. Top dressing methods vary. Storage nutrients are the material basis for the continuation of tree life in the year. The lack of growth will inevitably affect the normal sprouting, flowering, fruit setting, shoot growth, and root growth in the second year, and further affect the process of fruit enlargement, flower bud differentiation, etc.; vegetative growth is Basic, reproductive growth is the purpose, when the vegetative growth to a certain extent to promptly promote the transformation from vegetative growth to reproductive growth, soil fertilization to package fertilizer Jiamei profit-based, with little or no nitrogen fertilizer; foliar fertilization early with nitrogen In the main, phosphorus and potassium micro-based in the late, promote flower bud formation, with earlier results. After entering the full fruit period, reproductive growth dominates, and a large number of nutrients are used for flowering results. Fertilization requires nitrogen, phosphorus, and potassium to be used in combination such as Jiamei profit and brain platinum to increase the amount of nitrogen and potassium to meet fruit needs. Due to the small amount of farmyard manure, most of the organic fertilizers used today are chicken manure. If they are directly applied to the soil without being decomposed, various soil-borne diseases will enter the orchard to cause or aggravate certain diseases; in addition, burning of roots will occur. . If such fertilizers are applied for three consecutive years, the orchard may suffer destruction and lose production capacity. Phosphorus is too high, phosphorus and iron in the soil to form iron phosphate is insoluble in water, can not be absorbed and used, resulting in fruit iron deficiency, yellow leaf disease. Phosphorus and zinc in the soil form zinc phosphate, which can no longer be absorbed and utilized, leading to zinc deficiency and lobular disease. The lack of potassium in the soil affects the absorption of nitrogen, produces yellow leaves, reduces the formation of photosynthetic products in the leaves, and ultimately leads to a decrease in yield; in addition, excess potassium causes the soil to lack magnesium, which can also lead to yellow leaves. In general, fertilization is divided into three periods, including spring, fruit expansion, and autumn fertilization. The current situation is that most people apply fertilizer in the spring, but do not apply fertilizer in the autumn. A large amount of experimental data proves that there are many benefits of fertilization in the fall: 1. Fertilization after fruit harvesting can help restore tree vigor and guarantee high yield in the coming year; 2. This period is the peak period of root development. Fertilization is conducive to root absorption. It reserves large amounts of nutrients for flowering results in the coming year and can increase nutrient utilization. 3, autumn fertilization, can improve the cold resistance of fruit trees, reduce frost damage; 4, autumn fertilization will also damage part of the root system, just play a pruning effect to stimulate its growth. After harvesting fruits in autumn, they should be watered and fertilized immediately. In addition, some foliar fertilizers should be sprayed to maintain the leaf's long-term vigor and enhance photosynthesis to store more photosynthetic materials. Corn is a good choice for consumption during weight loss because of its high available energy. The metabolic energy of maize is 14.06 MJ/kg, with the highest being 15.06 MJ/kg, the highest of the cereal feeds. This is mainly due to the fact that there is very little crude fibre in maize, only 2%, while the nitrogen-free leachate is up to 72% and the digestibility is up to 90%; on the one hand, maize has a high crude fat content, between 3.5% and 4.5%.
