Method for keeping trichoderma spores alive in trichoderma bio-organic fertilizer product

Abstract

The invention discloses a method for keeping trichoderma spores alive in a trichoderma bio-organic fertilizer product. The method comprises the following steps: adding an acidolysis amino acid solution to a matured compost according to a certain addictive proportion, fully mixing, neutralizing, and carrying out first after-ripening, wherein the pH of the mixture is about 4 at the moment; then fully mixing formula amounts of chemical fertilizer with the amino acid compost of the first after-ripening, and then carrying out second after-ripening; determining the actual pH of the mixture, and thenadding a certain amount of the acidolysis amino acid solution for third after-ripening, so as to stabilize the pH of the product between 6 and 7; and finally, adding trichoderma solid strains, fullymixing and packaging. After one year of preservation of the trichoderma bio-organic fertilizer product prepared by the method, the spore concentration of trichoderma funguses is still more than 3*107per g, which is significantly larger than the agricultural industry standard (2*107 per g).

Description

technical field [0001] The invention belongs to the field of bio-organic fertilizers, and relates to a method for keeping alive Trichoderma spores in Trichoderma bio-organic fertilizer products. Background technique [0002] Bio-organic fertilizer (NY 884-2012 industry standard: organic matter≧40%, functional bacteria≧2×10 7 , moisture≦30%, pH 5.5-8.5) and compound microbial fertilizer (NY / T 798-2015 industry standard: organic matter≧20%, nitrogen, phosphorus and potassium nutrients 8-25%, functional bacteria≧2×10 7 , moisture ≦ 30%, pH 5.5-8.5) are currently the two leading varieties of microbial fertilizers in my country, which have contributed to the improvement of soil fertility and the resource utilization of solid organic waste in my country. However, we have recently collected 9 samples from the market, none of which contained functional bacteria reached the industry standard set by the Ministry of Agriculture (Table 1). The functional bacteria content of fresh samp...

Problems solved by technology

If the pH of the decomposed compost is not adjusted to below 7.5, it means that all biological fertilizers are organic fertilizers that only contain organic matter and do not contain functional bacteria. Therefore, adjusting the pH in biological fertilizer products is the key to making biological fertilizers. The most critical step, but the past biological fertilizer basically did not regulate its pH, which is the root cause of the poor effect of biological fertilizer
