Embodiment 1

[0024] Example 1: Preparation of efficient straw-degrading compound bacteria

[0025] The preparation of the efficient straw-degrading composite bacteria comprises the following steps:

[0026] (1) After inoculating different bacteria in the corresponding culture medium, incubate in a shaker at 30°C at 150r / min for 2 days with shaking. After the culture is completed, dilute to form a bacterial solution, so that the concentration is 200 million bacteria per milliliter. That is 200 million / ml;

[0027] The culture medium for Bacillus, Streptomyces grisea, and Streptomyces violaceum is: yeast extract 2.0g / L, glucose 8.0g / L, K 2 HPO 4 6.5g / L, NaNO 3 3.0g / L, NH 4 Cl 1.0g / L, NaCl 3.0g / L, MgSO 4 0.05g / L, MnSO 4 0.01g / L, FeSO 4 ·7H 2 O 0.005g / L, pH 7.5.

[0028] Paenibacillus medium: tryptone 15.0g / L, soytone 5.0g / L, NaCl 5.0g / L, pH7.3±0.2.

[0029] Trichoderma, Penicillium, Aspergillus niger medium: bran 10.0g / L, sucrose 10.0g / L, KH 2 PO 4 4.0g / L, MgSO 4 0.3g / L, natural ...

Embodiment 2

[0034] Example 2: Application of high-efficiency straw-degrading compound bacterial agent in rice straw composting

[0035]The rice straw is crushed to 10-15cm by crushing equipment to form a straw segment, and Ⅰ, Ⅱ, and Ⅲ composite bacterial agents are taken according to 1.5% of the weight of the straw, of which No. 1 bacterial agent accounts for 20%, No. 2 bacterial agent accounts for 50%; 30%. In the process of composting, add mixed bacterial agents evenly, turn the compost once every 6-7 days, and turn the compost 3 times in total, and adjust the water content of the compost to about 65%; after the second turn, the temperature drops to 45°C About 0.5% of the weight of the heap is added to the auxiliary bacterial agent, and then the third turning and fermentation is carried out, and the high-efficiency rice straw degradable organic fertilizer can be obtained after completion.

Embodiment 3

[0037] Example 3: Application of efficient straw-degrading compound bacteria in asparagus straw composting

[0038] The asparagus stalks are crushed to 5-10cm by crushing equipment to form straw segments, and Ⅰ, Ⅱ, and Ⅲ composite bacterial agents are taken according to 1% of the weight of the straws, of which No. 1 bacteria account for 25%, No. 2 bacteria account for 45%; In the process of composting, add mixed bacterial agents evenly, turn the compost once every 5-6 days, and turn the compost 3 times in total, and adjust the water content of the compost to about 65%; after the second turn, the temperature drops to 45°C About 0.5% of the weight of the heap is added with auxiliary bacteria, and then the third turning and fermentation is carried out. After the completion, the high-efficiency asparagus straw degradable organic fertilizer can be obtained.

[0039] In the composting fermentation process, from the 1st day, measure the temperature of heap every day, obtain a ferment...

Abstract

The invention relates to an efficient straw degrading composite fungicide (JFB-1) and an organic fertilizer preparing method thereof. The composite fungicide comprises composite bacteria and a carrier, wherein the carrier is wheat bran, and the composite bacteria include composite bacteria I, composite bacteria II, composite bacteria III and auxiliary bacteria. The composite bacteria I, II and III account for 1-1.5% of the weight of straws, wherein the composite bacteria I account for 20-25%, the composite bacteria II account for 45-50%, the composite bacteria III account for 30-35%, and the composite bacteria are added uniformly in compost fermentation so as to effectively improve the maturation speed and the quality of an organic fertilizer. The fungicide is fully mixed with straws of rice, asparagus and other crops to carry out compost fermentation, the straws can be degraded rapidly through the synergistic effect of the bacteria, the degradation efficiency is improved, the degradation time is shortened, and insect pests are effectively killed and are rapidly transformed into the organic fertilizer for improving soil. The efficient straw degrading composite fungicide can be used for effectively solving the problem of land occupation caused by landfill, or the problems of fire, traffic dangers, environment pollution and the like caused by burning.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a high-efficiency straw-degrading composite bacterial agent and a method for preparing organic fertilizer thereof. Background technique [0002] The method can treat many types of objects, such as rice, asparagus and other crop straws and other wastes with high cellulose content. Straw contains a lot of cellulose, hemicellulose, pectin, lignin, organic matter, nitrogen, phosphorus, potassium and trace elements, etc., and is rich in nutrients. If it is burned directly, it will not only pollute the atmospheric environment, cause fire hazards, cause traffic hazards, and affect the image of the city, but also have a low calorific value, resulting in waste of resources; if it is landfilled, although it can be degraded by the soil itself, the degradation time long-term, consumes nutrients in the soil, and has a low utilization rate; if it is piled up for a long time, ...
