Embodiment approach 1

[0044] This embodiment provides a method for preparing a straw-degrading composite microbial agent, which includes the following steps:

[0045] S1 collects vegetable stalks and cuts them into sections to obtain straw waste A with a length of ≤2 cm;

[0046] S2 mix the straw waste A obtained in step 1, cultivated soil, decomposed sheep manure, lemon peel and water evenly to obtain a mixture B with a water content of 60%, wherein the mass ratio of straw waste A, cultivated soil and decomposed sheep manure The ratio is 2:1:2, the culture soil is soil with an organic matter content of 1.75%, no pests and diseases, and a granular structure, and the lemon peel is 0.2%-2% of the mass of the straw waste A;

[0047]S3 gets the mixture B obtained in step 2 of 100 parts by weight, and inoculates 1 part by weight of EM bacterium liquid, 1 part by weight of saccharomyces liquid, 1 part by weight of Bacillus subtilis bacterium liquid and 0.5 Trichoderma harzianum bacterium liquid of weigh...

Embodiment approach 2

[0051] This embodiment provides a method for preparing a straw-degrading composite microbial agent, which includes the following steps:

[0052] S1 collects vegetable stalks and cuts them into sections to obtain straw waste A with a length of ≤2 cm;

[0053] S2 Mix the straw waste A, cultivated soil, decomposed duck manure, orange peel and water obtained in step 1 to obtain a mixture B with a water content of 70%, wherein the mass ratio of straw waste A, cultivated soil and decomposed duck manure 1.8:0.8:2.2, the culture soil is soil with an organic matter content of 1.82%, no pests and diseases, and a granular structure, and the orange peel is 1.8% of the mass of the straw waste A;

[0054] S3 gets the mixture B obtained in step 2 of 100 parts by weight, and inoculates 0.8 parts by weight of EM bacterium liquid, 0.8 parts by weight of saccharomyces liquid, 1.2 parts by weight of Bacillus subtilis bacterium liquid and 0.65 Trichoderma harzianum bacterium liquid of weight part...

Embodiment approach 3

[0058] This embodiment provides a method for preparing a straw-degrading composite microbial agent, which includes the following steps:

[0059] S1 collects vegetable stalks and cuts them into sections to obtain straw waste A with a length of ≤2 cm;

[0060] S2 mix the straw waste A, cultivated soil, decomposed chicken manure, pomelo peel and water obtained in step 1 to obtain a mixture B with a water content of 50%, wherein the mass ratio of straw waste A, cultivated soil and decomposed chicken manure The ratio is 2.2:1.2:2, the culture soil is soil with an organic matter content of 1.68%, no pests and diseases, and a granular structure, and the pomelo peel is 1.2% of the mass of the straw waste A;

[0061] S3 takes 100 parts by weight of the mixture B obtained in step 2, and inoculates 1.2 parts by weight of EM bacterium liquid, 1 part by weight of saccharomyces liquid, 1 part by weight of Bacillus subtilis bacterium liquid and 0.35 Trichoderma harzianum bacterium liquid of...

Abstract

The invention belongs to the technical field of vegetable straw recovery treatment and relates to a preparation method and application of a complex microbial agent for straw degradation. The method includes steps: S1, collecting vegetable straw, cutting into fragments, and smashing to obtain a straw waste material A; S2, well mixing the straw waste material A, culture soil, a nitrogen source and water to obtain a mixture B; S3, taking the mixture B, performing inoculation of EM bacterial fluid, saccharomycete fluid, bacillus subtilis fluid and trichoderma harzianum fluid, stirring, mixing, andfermenting for 3-5 days to obtain the complex microbial agent. The invention further provides a straw organic fertilizer and a straw returning treatment method. The complex microbial agent for strawdegradation has advantages that antagonism of dominant growth florae can be improved, flora and microbial diversity is improved, and great straw degradation effects and low production cost are realized.

Description

technical field [0001] The invention belongs to the technical field of vegetable straw recycling and processing, and in particular relates to a preparation method and application of a straw-degrading composite bacterial agent. Background technique [0002] According to the 2017 International Conference on Protected Horticulture, China has become the country with the largest protected gardening area in the world, and the amount of vegetable straws is large and difficult to clean. How to effectively deal with vegetable straws is one of the key issues that the protected horticulture industry urgently needs to solve. [0003] The common treatment method of vegetable straw is to mechanically chop or crush the vegetable straw in situ, and then sprinkle the chopped or crushed vegetable straw directly on the surface or apply it to the soil by mechanical deep plowing or rotary plow, Then apply the corresponding basal fertilizer to the soil to return the straw to the field; or directl...
