Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a biological fertilizer. Background technique

[0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers, or chemical fertilizers for short. It has the characteristics of simple ingredients, high content of active ingredients, easily soluble in water, fast decomposition, and easy absorption by roots, so it is called "quick-acting fertilizer".

[0003] In addition, in the last 10 years, the production-increasing effect of chemical fertilizers has also decreased significantly, and the growth rate of chemical fertilizer use has far exceeded the growth rate of crop production. According to statistics, the average amount of chemical fertilizers on cultivated land in my country has exceeded the internatio...
