Usually referred to as organic fertilizer cultivation mainly refers to the arrangement of a certain area of crops, green manure and forage grass in the rotation cycle to increase soil organic matter, improve soil structure, through its associated rhizobia fixed free nitrogen in the air, supplement and enrich the nitrogen nutrition in the soil, to achieve the purpose of organic fertilizer cultivation of the field. Organic fertilizer production line manufacturers will do a better job of equipment, so that our agricultural development is better developed. Ensure that organic fertilizer equipment and agricultural development complement each other. Under human intervention, the land can be planted for better or worse. The adoption of unreasonable farming system and neglect of the combination of use and cultivation often lead to the consumption of soil organic matter and the loss of nutrients, which leads to the destruction of soil structure, aggravates water erosion and wind erosion, and decreases the yield year by year. In response to this situation, as early as the middle of the 19th century, Germany's Liebig put forward the theory of return, advocating that through fertilization to recruit the nutrient elements taken away with the harvest, return to the soil. Later, according to his analysis of the soil formation process and the essence of agricultural production, Williams of the Soviet Union pointed out the dialectical relationship between nuclear production, animal production and soil acid management, and believed that agriculture, forestry and grazing must be combined in order to enrich soil acid and improve crop yield. On the basis of summing up the experience of traditional agricultural production, Chinese agricultural scientists have also come up with the principle of sufficient land, accumulation of nuclear land, and combination of cultivation. It is pointed out that the purpose of land use and the means of land cultivation are to ensure land use in order to provide more agricultural products. Before the establishment of the modern fertilizer industry, the main means of restoring and cultivating soil fertility were the application of farm fertilizers and biological cultivation. With the progress of science and technology, the effect of organic and inorganic fertilization is becoming more and more important.
