Embodiment 1

[0022] Example 1 Preparation of straw decomposing agent and detection of enzyme activity 1 Preparation of decomposing agent The decomposing agent used in this example to degrade straw consists of bacterial agent A, bacterial agent B, bacterial agent C and bacterial agent D. Bacterial agent A, bacterial agent B, bacterial agent C and bacterial agent D were prepared according to the following method: strain medium: rice bran 0.6g / L, bran 0.2g / L, straw powder 0.8g / L, soybean meal 0.4g / L, pH 7.0.

[0023] Candida tropicalis was cultivated in the culture medium of the above-mentioned strains at 28° C. and shaken at 200 r / min for 3 days. All the fermentation broth was collected and dried under low-temperature negative pressure as bacterial agent A.

[0024] Aspergillus oryzae was cultivated in the culture medium of the above-mentioned strains at 28° C. and shaken at 200 r / min for 3 days, and all the fermentation broth was collected and dried under low-temperature negative pressure a...

Embodiment 2

[0055] Example 2 Preparation of decomposing agent for degrading straw The decomposing agent used in this example for degrading straw includes bacterial agent A, bacterial agent B, bacterial agent C and bacterial agent D. Bacterial agent A, bacterial agent B, bacterial agent C and bacterial agent D were prepared according to the following method: strain medium: rice bran 0.6g / L, bran 0.2g / L, straw powder 0.8g / L, soybean meal 0.4g / L , pH 7.0.

[0056] Candida tropicalis was cultivated in the culture medium of the above-mentioned strains at 28° C. and shaken at 200 r / min for 3 days. All the fermentation broth was collected and dried under low-temperature negative pressure as bacterial agent A.

[0057] Aspergillus oryzae was cultivated in the culture medium of the above-mentioned strains at 28° C. and shaken at 200 r / min for 3 days, and all the fermentation broth was collected and dried under low-temperature negative pressure as bacterial agent B.

Embodiment 3

[0062] Embodiment 3 is used for the preparation of decomposing agent for degrading stalks except that the following technical characteristics are different, and other processes are all consistent with embodiment 1: Candida tropicalis (Candidatropicalis) in bacterial agent A, Aspergillus oryzae (Aspergillus oryzae) in bacterial agent B 1. The colony-forming unit (CFU) ratio of Trichodermaviride in bacterial agent C to Bacillus subtilis in bacterial agent D is 10:0.1:10:0.1.

[0063] The enzyme activity of the straw decomposing agent prepared in this example was measured by the method of Example 1, and the measurement results showed that the straw decomposing agent of the present invention had very high cellulase activity, protease activity and amylase activity.

Abstract

The invention relates to a decomposition maturing agent for degrading straw. The agent comprises active ingredients, such as candida tropicalis, aspergillus oryzae, trichoderma viride and bacillus subtilis. The decomposition maturing agent can rapidly decompose wheat straw, rice straw, grain straw, sweet potato stems, broad bean stems, rape stalks, weeds, leaves and household garbage of which the fibrous matter content is high so as to prepare an organic fertilizer. The decomposition maturing agent has the advantages of short degradation time and capability of effectively killing diseases and pests and providing nutrients for crops.

Description

technical field [0001] The invention relates to a decomposing agent for degrading straw, in particular to a decomposing agent for straw with short degradation time, stable decomposition effect and decomposing effect at normal temperature. Background technique [0002] At present, due to the excessive use of chemical fertilizers in rural areas of our country, the soil organic matter and beneficial microbial flora and quantity have decreased, and the physical and chemical conditions of the soil have deteriorated seriously, which will inevitably affect the sustainable development of agriculture and the deterioration of the ecological environment. To this end, the country has adopted a series of policies aimed at improving soil organic matter, improving soil, and reducing environmental pollution, and invested a lot of manpower, material resources, and financial resources to improve the above conditions. [0003] Crop stalks have a large quantity, variety and wide distribution. ...
