Embodiment 1

[0044] (1) Preparation of high-efficiency compound microbial fermentation inoculant

[0045] Trichoderma konii, white rot fungus, Trametes versicolor, EM bacteria, nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria were expanded and cultivated on the corresponding medium. Shake well in a sterile Erlenmeyer flask to form a bacterial suspension; ② Inoculate the slant culture in a seed bottle, and incubate at 30°C, 200r / min for 24 hours to obtain a seed liquid; ③ Inoculate 10% of the seed liquid into a fermentation bottle and expand the culture for 44 hours to obtain a fermentation Liquid, according to the ratio of 15:15:15:25:10:10:10 to prepare high-efficiency compound microbial fermentation broth.

[0046] (2) Preparation of decomposed organic matter:

[0047] In terms of parts by mass (the same below), 74 parts of crushed air-dried cotton stalks, 15 parts of soybean meal, 10 parts of chicken manure, and 1 part of high-efficiency...

Embodiment 2

[0057] The preparation of high-efficiency composite microbial fermentation inoculant, decomposed organic matter, Trichoderma fermented liquid and actinomycetes fermented liquid is the same as embodiment 1. The difference is that the preparation of disease-preventing biological organic fertilizer is as follows:

[0058] Add 2 parts of Trichoderma fermented liquid to 98 parts of decomposed edible fungus slag, adjust the moisture content to 68%, pH 6.8, fully mix, pile up into a strip-shaped stock pile with a height of 0.5 meters, cover the sack, and control the stock pile. The temperature is 25-30°C, the compost is turned once a day, and the co-fermentation is carried out for 7 days. In addition, 2 parts of actinomycetes fermented liquid were added to 98 parts of decomposed edible fungus residues, the moisture content was adjusted to 60%, the pH was 7.3, fully mixed, piled up into a 0.5-meter-high strip-shaped pile, covered with a plastic film, Control the temperature of the ...

Embodiment 3

[0060] (1) The preparation of the high-efficiency composite microbial fermentation inoculant is the same as in Example 1;

[0061] (2) Preparation of decomposed organic matter:

[0062] In terms of parts by mass (the same below), 55 parts of pulverized air-dried cotton stalks, 28 parts of soybean meal, 15 parts of chicken manure, and 2 parts of high-efficiency composite microbial fermentation inoculum were fully mixed evenly. Adjust the water content of the mixture to 58%, C / N to 25, and pH to 7.5.

[0063] Pile the above-mentioned mixed materials into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, the number of holes per square meter is 15, cover with sacks, and carry out aerobic fermentation. When the temperature of the heap rises to 50°C, start counting and ferment for 7 days. When the temperature of the stockpile starts to drop, turn the pile and ferment for another 7 days, then turn the pile every 7 days for a total of 35 days of fermenta...

Abstract

Relating to the technical field of renewable energy, the invention specifically relates to a method for producing biogas and organic fertilizers with straw. The method of the invention comprises the steps of: (1) straw pretreatment; (2) straw composting; (3) anaerobic fermentation; and (4) fermentation product utilization. The method of the invention substantially improves the degradation rate of straw and gas output. Meanwhile, pretreatment by a composite bacterial agent can stabilize the pH value of a fermentation system, and is in favor of the normal occurrence of anaerobic fermentation, so that the content of methane in biogas can be raised. The method in the invention greatly saves cost, almost has no sewage discharge, and improves the utilization rate of renewable energy. The biogas produced by anaerobic fermentation of crop straw can be used as a resident cooking fuel or for power generation after treatment by the purification procedures of desulphurization and dehydration. On the other hand, the residue generated from anaerobic fermentation of straw can be separated into a biogas residue and biogas slurry that are then prepared into solid and liquid organic fertilizers, which are easy for crops to adsorb. Therefore, the comprehensive utilization rate of straw resources can be substantially enhanced.

Description

technical field [0001] The invention relates to a disease-prevention bio-organic fertilizer produced by using bio-control Trichoderma, actinomycetes and crop stalks as main raw materials and a preparation method thereof, belonging to the technical field of bio-organic fertilizer production. Background technique [0002] Crop straw is an important biological resource in the crop production system, and it is also the fourth largest energy source in the world after coal, oil and natural gas. According to incomplete estimates, the world can produce nearly 2 billion tons of straw every year, while the annual output of crop straw in my country is about 600-700 million tons, ranking first in the world, and mainly corn, wheat, cotton and rice straw, accounting for 82% of the total straw production. How to make full use of these resources without polluting the environment is a difficult problem for modern agriculture. [0003] At present, in straw utilization, fertilizer (including ...
