The apple is one of the largest tree species cultivated in the north. According to its maturity, it can be divided into Zhuguang, Hongyu, Marshal, Golden Crown, Green Banana, India, and Fuji. "," "Guoguang" and so on. In early and late August, many early maturing varieties have been listed one after another. However, due to heavy rainfall this year, the orchards of some growers have appeared “small and large†phenomenon. This phenomenon directly affects the yield of apples and the economic benefits of farmers. Farmers tend to focus only on the application of pre-harvest fertilizers and resultant fertilizers, ignoring the application of basal fertilizers after defoliation of apple trees at the end of September (also known as "monthly sub-fertilizers"). The annual application of inorganic fertilizers results in soil compaction, and the depth of the apple tree roots becomes shallower, so that no more trace elements can be absorbed from the deeper layers of the soil, and many insoluble nutrients in the inorganic fertilizer are adsorbed and fixed in the soil, destroying the aggregates of the soil. The structure reduces the aeration, water permeability, water retention and fertilizer retention of the soil. Many years of practice have proved that combined application of the microbial fertilizer microbial fertilizer (especially "monthly child fat"), can improve the ability of the tree to resist cold and drought, promote flower bud differentiation, regulate soil pH, reduce Apple "shrink" and "water heart" And other physiological diseases, improve the tree's stress resistance, and ultimately achieve high apple yield. There are four major advantages of the golden baby microbial fertilizer in apple high-yield fertilization:
First, increase fertilizer utilization. Different types of apple trees in different ages require different types of fertilizers and different amounts of fertilizers. During sapling stage, nutrient growth is strong and requires more nitrogenous fertilizer. Ammonium-based nitrogen fertilizers should be used, supplemented with appropriate amounts of phosphate fertilizers. During the fruit period, due to its large number of results, the demand for phosphorus and potassium fertilizers increased. Based on the use of nitrogen fertilizer, the application amount of phosphorus and potassium fertilizers needs to be increased. In particular, attention should be paid to the application of potash fertilizers to improve the fruit quality. In the senescence period tree, while ensuring the phosphorus and potassium fertilizers, it is appropriate to increase the nitrogen fertilizer to promote the renewal and growth of the aging tree. The azotobacter factor and phosphorus-solubilizing factor in the baby microbial fertilizer can fix nitrogen in the air and release insoluble phosphorus and potassium factors fixed in the soil by fertilizers, providing sufficient nutrients for apple trees of different ages.
Second, assist and promote the absorption of other nutrients by apple trees. Apple trees of different ages require a certain amount of trace elements such as calcium, boron, manganese, zinc, molybdenum in addition to nitrogen, phosphorus, and potassium to ensure the normal growth of apple trees. The microbial species in the golden baby microbial fertilizer can multiply in the rhizosphere soil environment of apple trees. Metabolites such as gibberellins, cytokinins, indoleacetic acid and the like can promote root growth, thereby allowing root absorption. The trace elements in the deep soil reduce the occurrence of physiological diseases.
Again, enhance the stress resistance of apple trees. When the microbial species in the golden baby microbial fertilizer propagated in the maize rhizosphere soil environment, a protection circle was formed around the apple tree root system, which reduced the formation and infringement of other harmful bacteria groups, thereby reducing the occurrence of apple tree root diseases.
Finally, fertilize the soil. The metabolites of microbial species in the golden baby microbial fertilizer increase the amount of organic matter in the soil, promote the formation of soil aggregate structure, and enhance the ability of soil to ventilate, permeable, and retain water and fertilizer.
In addition, apple trees can be properly applied to microbial fertilizer, which can save about 30% of chemical fertilizers, and can increase the utilization rate of chemical fertilizers. It can also promote the early entry of fruit trees into the fruiting period and achieve the purpose of early maturity, high yield, and high quality.
