Biological organic fertilizer starter and preparation method thereof

Abstract

The invention provides yeast for bio-organic fertilizer and a preparation method of the yeast. The yeast is prepared through the following steps: bacillus subtilis powder, bacillus subtilis subsp.subtilis powder, bacillus megaterium powder and bacillus mucilaginosus powder are taken and uniformly mixed; a plant growth regulator dissolved in ethyl alcohol is mixed uniformly with filler, the mixture is added to the mixed bacteria powder and stirred uniformly, the yeast is obtained, and the total count of the prepared yeast is larger than or equal to 10<10> CFU / g. With adoption of multiple microorganisms and an aerobic composting fermentation technology, specific functional advantages of the bacteria can be exerted, further, by addition of a microbial growth promoter, the organic matter degradation rate can be increased greatly, organic matter is degraded and transformed rapidly under the action of the compound microorganisms, plant growth hormones for promoting plant growth are increased in the fertilizer, and the yeast and the preparation method have the characteristics that the preparation process is simple, the product quality is stable and reliable, the cost is low and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and relates to a biological organic fertilizer starter and a preparation method of the starter. Background technique [0002] Soil is the foundation of agriculture, and fertilizer is the food of crops. my country is the largest agricultural country in the world and requires a large amount of fertilizer every year. Fertilizer is a fertilizer containing one or several nutrients needed for the growth of crops. The macronutrient elements needed for crop growth include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and the micronutrient elements include boron, copper, iron, manganese, molybdenum, zinc, and chlorine. The use of fertilizers has greatly promoted the development of agricultural production and greatly increased the yield of crops, which is of great significance to the development of the national economy and the promotion of agricultu...

AI Technical Summary

Problems solved by technology

Because some of them do not produce spores, they will be killed due to high temperature during the fermentation process of organic fertilizer, and cannot play the role of microorganisms; at the same time, various enzymes are inactivated due to high temperature generated by fermentation, and cannot play a role. Bioenzymes can degrade macromolecular substances, and there are disadvantages such as short survival time of starter bacteria, difficulty in stabilizing fermentation effect, complex production process and high production cost
