preparation example Construction

[0021] The steps of the method for preparing the composite straw microbial decomposing agent of the present invention include: seed cultivation by conventional methods, industrial expansion culture, concentration of the culture solution, freeze-drying to make bacteria powder, and then weighing the bacteria according to the components of the composite straw microbial decomposing agent Mix the powder and get it. The method for preparing bacterial powder in the example of the present invention is as follows:

[0022] Seed culture: each microbial strain is respectively inoculated in a triangular flask culture medium, the culture temperature is 25-37℃, the oscillator speed is 130-230r / pm, and the culture time is 12-36 hours.

[0023] Industrial expansion culture: (1) Connect the triangular flask seeds to the first-level seed fermentor for cultivation, the cultivation temperature is 25-37℃, the mechanical stirring speed is 120-230r / pm, the aeration volume suitable for the growth of micro...

Abstract

The invention belongs to the field of a microbial technology and relates to a straw microbial decomposition agent composed of a plurality of microbial probiotics and a preparation method thereof. The straw microbial decomposition agent has a low cost and a small amount of use, is convenient to use and can accelerate the decay of the crop waste straws. Straws are decomposed to form simple organic matters and humus so that soil is loosed and soil pH is improved. The composite straw microbial decomposition agent forms factors based on soil humic acid and humus and decomposes straw cellulose. The straw microbial decomposition agent comprises, by weight, 15 to 32 portions of yeast powder, 15 to 21 portions of filamentous fungus powder and 43 to 67 portions of cellulose-decomposing bacterium powder. The straw microbial decomposition agent has effects of fertilizing soil, enhancing the ability of preserving moisture and fertility and improving the comprehensive productivity of soil, has the advantages of small dosage, use convenience and wide application range, and prevents the environmental pollution caused by crop wastes.

Description

Technical field [0001] The invention belongs to the technical field of microorganisms, and specifically relates to a straw microbial decomposing agent composed of a variety of microbial protozoa and a preparation method thereof. Background technique [0002] The long-term and high-load open agricultural ecosystem characterized by high multiple cropping index has made the only agricultural resource arable land overwhelmed and has brought a greater negative impact on agriculture. On the one hand, the large amount of straw waste produced in agricultural planting areas with high multiple cropping index has become a pollution source that pollutes land, water and air; on the other hand, the increase in multiple cropping index has greatly increased the consumption of chemical fertilizers, sharply deteriorated the physical and chemical properties of soil, and adjusted soil water The humus of fertile, gas, and hot soil is decreasing year by year, the number of microorganisms in the soil i...
