Problems solved by technology

Since the product of gibberellin fermentation is basically C20 gibberellin, its activity is poor, so the application dose is relatively large, which is likely to produce crop residues and cause food safety hazards; in addition, the application dose of plant growth hormone is relatively large, and the It is easy to inhibit the growth of crops or even cause the death of crops at the wrong time, but it will have adverse effects on the increase of crop production.

Abstract

The invention discloses amino acid compounded liquid fertilizer and a preparation method thereof. The amino acid compounded liquid fertilizer is prepared from components in percentage by weight as follows: 10%-15% of a compound amino acid liquid, 3%-4% of a concentrated ribonucleic acid solution, 1.5%-3.5% of traditional Chinese medicine fermentation broth and the balance of water. According to the amino acid compounded liquid fertilizer and the preparation method, morning glory seed is fermented with bacillus subtilis, gibberellin glucoside and gibberellin glucose ester which are bound gibberellin without physiological activity in the morning glory seed are converted into C19 gibberellins through deglycosylation, so that the physiological activity of the morning glory seed is improved greatly, and the yield increasing effect on crops is improved greatly. The traditional Chinese medicine fermentation broth can also have great yield increasing effect when the content of the gibberellins is extremely low (50-500 ng / ml), crop growth cannot be inhibited, gibberellin residues are avoided, and the safety of the crops as food is improved greatly.

Description

Technical field [0001] The invention relates to a liquid fertilizer, in particular to an amino acid compound liquid fertilizer and a preparation method thereof. Background technique [0002] At present, my country's farmland mainly uses chemical fertilizers containing nitrogen, phosphorus, and potassium and a small portion of solid fertilizers such as animal manure. In order to achieve the purpose of increasing production, it has to be applied many times a year, causing a great burden on farmers in terms of human and financial resources. Although animal manure has good fertilizer efficiency, the source is limited and the smell is bad, which restricts the large-scale use of animal manure. The large-scale application of chemical fertilizers will cause soil physique cracking and even reduce production. In addition, the mass production of chemical fertilizers will cause environmental pollution. Compared with solid fertilizer, liquid fertilizer has the advantages of high fertilizer e...
