The law of scientific fertilization

    China is an ancient agricultural country. In ancient times, there was a saying that fertilization "looks at the sky, the ground, and the crops". It means that scientific fertilization should determine a specific fertilization plan based on climate and weather, soil fertility and crop conditions. Of course, organic fertilizer was applied at that time. But the ancestors have summed up the essence of scientific fertilization.

     Modern agriculture pays attention to the unification of economic and ecological benefits. Take agricultural fertilization as an example. Scientific and reasonable is what modern agriculture needs. This can not only reduce the cost of fertilizers, but also create a more suitable soil environment for the growth of crops. . In fact, with the development of agricultural economy nowadays, the application of fertilizer is increasing. Although it has brought great benefits to the harvest of crops, if the fertilization method is unscientific and unreasonable, it will be waste and waste of chemical fertilizers. The problem of fertilizer damage to crops.

    "Crop nutrition law" refers to the biological law of crops, the law of crop nutrient requirements, the law of soil nutrient supply, the law of crop yield and quality formation, and the regulation of crop yield and quality.

    The biological laws of crops are the basis of scientific fertilization. Any crop has its own unique biological laws, both commonality and characteristics. For example, crops do not absorb nutrients from the soil in the early stage of germination, and mainly use the nutrients stored in the seeds. So, how long is this period? How big is the difference between crops with large seeds and small seeds? Different crops have different requirements for nutrients.

    No matter how advanced the fertilization technology is, the ultimate goal is to meet the nutrient needs of crops. Under the premise of high-yield crops, the total nutrient requirements of crops, the nutrient concentration of optimal nutrients and its phase characteristics, the starting point and end point of rapid nutrient absorption by crops are extremely critical for scientific fertilization. Different nutritional elements not only have their own unique nutritional effects, but also influence each other.

    Part of the nutrients absorbed by crops comes from the nutrients stored in the soil itself, and the other part comes from fertilization. There is no doubt that efficient fertilization is to allow crops to fully absorb the nutrients provided by the soil, while minimizing the amount of fertilizer required.

Although the yield and quality of crops are mainly determined by their genetic background, they are profoundly affected by nutrients and water supply. Understanding how plant nutrients affect yield and quality formation is of decisive significance for guiding fertilization.

    With the improvement of living standards, residents have higher and higher demands for the quality of crops. The supply of nutrients has a profound impact on the quality of crops. Therefore, mastering the formation rules of crop nutrient supply and product quality and yield plays a particularly important role in improving quality and efficiency at present.
