At present, some organic fertilizers, biological bacterial fertilizers and amino acid liquid fertilizers appear according to social demands. The organic fertilizer is prepared by fermenting, decomposing, crushing and carrying out granulation on animal wastes, and the general evaluation standard is the content of organic matters and nitrogen, phosphorus and potassium contained in the organic fertilizer; the biological bacterial fertilizer is produced by taking bacillus as a main raw material and artificially culturing the bacillus, and the general evaluation standard is how many effective bacteria are contained; the amino acid liquid fertilizer is prepared by taking lignite and peat as raw materials and acidifying the raw materials; the probiotic bacteria such as EM bacteria of Japanese invention can reach more than 80 kinds, and sugar is used as medium to decompose fruit to form liquid. But the organic fertilizer consumes more raw materials, is not completely decomposed, produces little absorption of products and crops, takes labor for application, has high cost and slow effect; the biological bacterial fertilizer has various soil conditions, and the fertilizer effect is greatly limited for the mode of playing the fertilizer effect by depending on the activity of beneficial bacteria. The amino acid liquid fertilizer is firstly acidified and decomposed by acidic substances, if the acidic substances are decomposed by chemical calculation, the amino acid liquid fertilizer cannot be called an organic fertilizer, meanwhile, the amino acid liquid fertilizer can only provide partial nutrient requirements for crops, and other growth hormones and fertilizers must be added to promote the growth of the crops; EM bacteria have many fungi, decomposed substances are complicated and unstable, and the EM bacteria have a certain effect on the growth of crops, but the EM bacteria cannot supply different fertilizer requirements of crops in different growth periods in a quantitative mode and cannot meet the cultivation requirements of modern agriculture.

In view of this, this patent is filed.
