Problems solved by technology

[0002] At present, the total nutrient content of domestically produced microbial fertilizers is generally within 25% due to the particularity of microbial agents. The industry standard NY / T798-2015 for compound microbial fertilizers issued by the Ministry of Agriculture also stipulates that the total nutrient content should be within 25%. The nutrient content of these products is reduced, and they generally need to be used with inorganic fertilizers such as compound fertilizers or urea when used, which is costly and complicated to use

Abstract

The invention discloses a macroelement water-soluble fertilizer containing microorganisms. The macroelement water-soluble fertilizer comprises a microbial agent and a macroelement fertilizer, trichoderma or bacillus is respectively cultured and fermented by using a culture medium, so as to obtain a fermentation liquid; the obtained fermentation liquid is subjected to centrifuging and the centrifuged product is subjected to drying, and a microbial agent is respectively prepared; the content of the total nutrient N+P2O5+ K2O in the macroelement water-soluble fertilizer containing microorganismsis larger than or equal to 50%, wherein the content of the microbial agent accounts for 0.1-10% of the mass of the water-soluble fertilizer. The invention further discloses a production method of thewater-soluble fertilizer. According to the invention, the nutrient content of the microbial fertilizer is improved to be more than 50% and even more than 70%, and a microbial agent which exists in thespore state and the endospore state is added, so that the nutrient content of the product is increased, the method for producing the microbial fertilizer is also expanded, and a new idea is providedfor the development of the industry.

Description

technical field [0001] The invention relates to a water-soluble fertilizer containing a large amount of microorganisms and a production method thereof. Specifically, it is a total nutrient N+P 2 o 5 +K 2 O ≥ 50%, microbial fertilizer water-soluble fertilizer with added microbial agent, finished product effective viable bacteria number ≥ 200 million / g and production method thereof. Background technique [0002] At present, the total nutrient content of domestically produced microbial fertilizers is generally within 25% due to the particularity of microbial agents. The industry standard NY / T798-2015 for compound microbial fertilizers issued by the Ministry of Agriculture also stipulates that the total nutrient content should be within 25%. The nutrient content of these products is reduced, and they generally need to be used with inorganic fertilizers such as compound fertilizers or urea when used, which is costly and complicated to use. [0003] In microbial fertilizers, e...
