Agricultural liquid microbial preparation containing micromolecular water-soluble organic carbon and preparation method for agricultural liquid microbial preparation

Abstract

The invention discloses an agricultural liquid microbial preparation containing micromolecular water-soluble organic carbon and a preparation method for the agricultural liquid microbial preparation. The weight of water-soluble organic matters accounts for 20.9% to 24.7% of the total weight of the agricultural liquid microbial preparation, the weight (by carbon) of the micromolecular water-soluble organic carbon in the water-soluble organic matters accounts for 11.97% to 14.25% of the total weight of the agricultural liquid microbial preparation, and the amount of live bacteria of bacillus subtilis is 2*10<8> / ml. The agricultural liquid microbial preparation is prepared from the following ingredients in parts by weight: 92-97 parts of organic-carbon active solution, 1.5-2.5 parts of urea, 0.8-1.2 parts of potassium dihydrogen phosphate and 1.5-2.5 parts of bacillus subtilis preparation. According to the agricultural liquid microbial preparation containing the micromolecular water-soluble organic carbon and the preparation method for the agricultural liquid microbial preparation, the organic-carbon active solution has a fertilizer effect and can also serve as a carbon source for the bacillus subtilis, so that the bacillus subtilis can survive for more than 1 year; and the bacillus subtilis can excellently assist the organic-carbon active solution in application effect, the organic-carbon active solution and the bacillus subtilis are limited to some extent in respective field of application when the organic-carbon active solution and the bacillus subtilis are separated, and the effect that 1+1 is greater than 2 is achieved when the organic-carbon active solution and the bacillus subtilis are excellently combined together.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and in particular relates to a liquid agricultural microbial preparation containing small molecule water-soluble organic carbon and a preparation method thereof. Background technique [0002] Carbon is the first of the macroelements necessary for plants and the energy source for metabolism. Based on the "chemical plant nutrition" established by western scholars more than 170 years ago, my country's classic plant nutrition and soil fertilizer science only recognize that the carbon needed by plants comes from CO 2 Gases are absorbed by leaves and chlorophyll photosynthetically converts a carbon "channel", ignoring the fact that plants can absorb small molecules of water-soluble organic carbon through roots. Since people have neglected the importance of supplementing carbon to plant roots, and the carbon source obtained by photosynthesis of plants is generally not enough, such a "carbon short ...

Problems solved by technology

After years of application and promotion of functional microorganisms, these functional effects have been recognized, but there are still some difficult problems in functional microorganisms at present: 1. The current functional microorganism products mainly use solid insoluble substances as carriers, and in water and fertilizer integration facilities It is difficult to apply it in agriculture. Some functional microbial products use liquid water-soluble as the carrier, but the survival time of the viable count is very short. Generally, the complete shelf life is only two months. By the third month, the viable count is basically Only half is left, and after another month, the number of viable bacteria will all die, which makes it difficult to adapt to the market

2. Many functional microbial products do not have their own "rations". When these functional microorganisms are put into barren soil, they cannot survive, let alone reproduce
