Problems solved by technology

However, there are still two obvious shortcomings in the microbial fertilizers currently sold on the market and used in agriculture. First, many products have single strains and functions, and cannot be widely adapted to a variety of crops; second, foreign commercial microbial fertilizers are often Inability to make use of local raw materials according to local conditions

Embodiment 1

[0030] Utilize silkworm excrement to ferment and prepare the method for composite microbial bacterial fertilizer, the steps are as follows:

[0031] (1) Spread out the stockpiled silkworm excrement, expose it to the sun for 3 days for disinfection, then dry it until the water content is 10% by weight, crush it to 50 mesh, and obtain the silkworm excrement matrix for later use; the silkworm excrement refers to the The accumulation of silkworm dung, silkworm slough and residual mulberry leaves left by silkworms;

[0032] (2) Put the strain culture medium in a stainless steel drum and rotate it for 28 minutes at a speed of 120 rpm and a temperature of 110°C. After the temperature of the culture medium drops to room temperature, spray the culture medium with clean water until it is wet, press Inoculate 5 different strains at a weight ratio of 1:100 between the strain and the medium, and ferment and culture them for 12 hours at a speed of 120 rpm, pH=7.4 and a temperature of 40°C f...

Embodiment 2

[0038] Utilize silkworm excrement to ferment and prepare the method for composite microbial bacterial fertilizer, the steps are as follows:

[0039] (1) Spread out the stockpiled silkworm excrement, sterilize it under ultraviolet light for 1-3 hours, then dry it until the moisture content is 8%, crush it to 40 mesh, and obtain the silkworm excrement substrate for later use; the silkworm excrement Sand refers to the accumulation of silkworm manure, silkworm slough and residual mulberry leaves left over from silkworm rearing;

[0040] (2) Put the strain culture medium in a stainless steel drum, and rotate it for 32 minutes at a speed of 120 rpm and a temperature of 120°C. After the temperature of the culture medium drops to room temperature, spray the culture medium with clean water until it is wet, press Inoculate 5 different strains at a weight ratio of 1:100 between the strain and the culture medium, and ferment and culture them for 12 hours at a speed of 120 rpm, pH=7.4 and ...

Embodiment 3

[0047] Utilize silkworm excrement to ferment and prepare the method for composite microbial bacterial fertilizer, the steps are as follows:

[0048] (1) Spread the piled silkworm excrement, expose it to the sun for 3 days for disinfection, or sterilize it under ultraviolet light for 1-3 hours, then dry it until the water content is less than 10%, crush it to less than 50 mesh, and get The silkworm excrement substrate is standby; the silkworm excrement refers to the accumulation of silkworm dung, silkworm slough and residual mulberry leaves left over from silkworm rearing;

[0049] (2) Put the strain culture medium in a stainless steel drum, and rotate it at a speed of 120 rpm and a temperature of 130°C for 35 minutes. After the temperature of the culture medium drops to room temperature, spray the culture medium with clean water until it is wet, press Inoculate 5 different strains at a weight ratio of 1:100 between the strain and the medium, and ferment and culture them for 12...

Abstract

The invention discloses a method for preparing composite microbial fertilizer by fertilizing silkworm excrement. The method comprises the following steps: 1, exposing the stacked silkworm excrement under the sun, and sterilizing the stacked silkworm excrement for standby application; 2, fermenting and culturing bacillus subtilis, bacillus mucilaginosus, bacillus thermoamylovorans, azotobacter chroococcum and streptomyces microflavus in respective sterilized culture medium under respective suitable conditions for 12 hours; 3, inoculating the five fermented cultured strains into a silkworm excrement culture medium, covering the silkworm culture medium by utilizing a film, and stacking and fermenting for 10 to 15 hours; 4, naturally cooling the fermented silkworm excrement to the ambient temperature, spreading the fertilizer compost, and naturally drying the fertilizer compost to obtain the composite microbial fertilizer. The composite microbial fertilizer is rich in microbial flora beneficial to the soil and crop nutritional substances and capable of improving the soil fertility, improving the soil structure and physical characters and improving the yield and quality of crops.

Description

technical field [0001] The invention relates to a production method of a compound microbial bacterial fertilizer, in particular to a method for preparing the compound microbial bacterial fertilizer for various crops by using the leftover silkworm excrement of sericulture as a substrate through fermentation. Background technique [0002] my country has more than 1.8 billion mu of arable land and uses about 150 million tons of chemical fertilizers every year. It is the world's largest producer, importer and user of chemical fertilizers. The mass production and application of chemical fertilizers not only consumes a large amount of valuable resources such as coal, oil and natural gas, but also consumes a large amount of energy and power, and also causes soil compaction and degradation and extensive environmental pollution. Part of the chemical fertilizers applied on farmland inevitably enters rivers, lakes, and seas, causing eutrophication of inland and offshore water bodies in...
