Experts in fruit trees talked about fertilization. They all compared the effect of fertilization in different seasons of fruit trees to “Autumn in autumn, Silver in winter, and fertilization in spring is rotten ironâ€. The same input, the same fertilizer, the time effect of fertilization is quite different. The third growth peak of the roots of fruit trees from the end of August to the autumn of September is the third peak of growth. With the gradual decrease of temperature and the increase of autumn rain, the reproduction of microorganisms has accelerated, giving rise to a suitable growth environment for the roots of fruit trees. . From late August to September, it is also the flower bud differentiation stage of fruit trees, and fruit enlargement also requires a lot of nutrients. In this period, the lack of fertilizer can easily lead to poor flower bud differentiation. In the following year, it seems to be a flower bud. After flowering, it is a leaf bud. Therefore, fertilization in autumn is very important. The amount of fertilization in autumn accounts for 60% of the annual fertilization, and it is the key fertilizer to solve the size of the year. The fertilization in autumn should be dominated by organic fertilizers, supplemented by phosphorus and potassium fertilizers. If a large amount of nitrogen fertilizer is added, it will stimulate the re-growth of fruit trees, weaken the ability of fruit trees to store nutrients, make the fruit trees not fall into the normal leaves, and increase the chance of rot disease spreading to the trees. The application of organic fertilizer increases the ability of the tree to store nutrients and lays a solid foundation for flower bud differentiation and fruit enlargement. For fruit trees to maximize their production potential, organic fertilizers must be added to supplement the trace elements. In addition to the three elements of nitrogen, phosphorus, and potassium, organic fertilizer contains trace elements such as boron, zinc, manganese, molybdenum, copper, and iron. The organic fertilizer contains relatively complete nutrients and has a stable fertilizer effect, which can last for a long time. The use of fertilizers has solved the disadvantages of a single composition of inorganic fertilizers. Various organic acids in organic fertilizers combine with calcium and magnesium ions to form a stable complex, which can reduce the fixation of mineral nutrition. After the organic fertilizer is applied to the soil, the soil structure can be improved, and the soil water, fertilizer, gas and heat conditions can be adjusted, which is conducive to the robust growth of fruit trees. The application of organic fertilizers can meet the needs of fruit trees for various nutrients. Therefore, fertilizing organic fertilizers in the autumn cannot be lacking.
