Embodiment 1

[0037] Wheat straw decomposing agent, including Bacillus subtilis, Trichoderma viride, Aspergillus niger, white rot fungus and Candida, among them, Bacillus subtilis≥0.6 billion cfu / g, Trichoderma viride≥0.5 billion cfu / g, Aspergillus niger≥ 040 million cfu / g, white rot fungus ≥ 060 million cfu / g, Candida ≥ 020 million cfu / g, the wheat straw decomposing agent is liquid.

Embodiment 2

[0039] The preparation method of the above-mentioned wheat straw decomposing agent comprises the following specific steps:

[0040] 1), preparation medium:

[0041] A. Preparation of LB liquid medium: Dissolve 10g of tryptone, 5g of yeast extract and 10g of NaCl in a 1L volumetric flask, adjust the pH value to 7.0-7.5 with 1M NaOH, dilute to 1L with water, and then pressurize at 121°C Sterilize for 20 minutes;

[0042] B, prepare LB solid medium: add agar in the LB liquid medium prepared in step A, the addition of agar is 15g / L;

[0043] C. Prepare PDA liquid culture medium: Dissolve 200g of potatoes and 20g of glucose in a 1L volumetric flask, dilute to 1L with water, and then autoclave at 121°C for 20min;

[0044] D, prepare PDA solid medium: add agar in the PDA liquid medium prepared in step C, the addition of agar is 15g / L;

[0045] E. Preparation of PDA liquid induction medium: Dissolve 200g of potatoes, 5g of glucose, and 15g of sodium carboxymethylcellulose in a 1L v...

Embodiment 3

[0061] Analysis of the decomposing effect of the above-mentioned wheat straw decomposing agent:

[0062] Pile fresh wheat straw into a heap of 60 × 5 × 2m, carry out micro-spray watering on the wheat straw heap, continue to spray water for 3 days, stop watering when the moisture reaches 70wt%, and use the wheat straw decomposing agent prepared by the present invention according to 0.3wt% is diluted and sprayed into the wheat straw heap, and several bags of urea are evenly sprinkled to adjust the carbon-nitrogen ratio. The wheat straw heap is numbered (X).

[0063] In the same way, two wheat straw heaps of the same size were piled up as a control. One of the piles (Y) used the same quality of other brands of bacteria and urea of ​​the same quality; the other pile (CK) was used as a control and only sprinkled The same quality of urea, no fungicide.

[0064] 1. Straw pile temperature

[0065] from figure 1 It can be seen that the temperature of the three piles (X, Y, CK) can r...

Abstract

The invention discloses a wheat straw decomposition agent and a method for preparing the same. The wheat straw decomposition agent and the method have the advantage that bacillus subtilis, trichoderma viride, aspergillus niger, white rot fungi and candida are used as production strains, are free of antagonism and easy to cultivate and are nontoxic and harmless, and excellent wheat straw degradation effects can be realized; the method for preparing the wheat straw decomposition agent is simple, the strains are easily available and are convenient to store and low in cost, and obvious decomposition effects can be realized; the yield of crops can be greatly increased by decomposed wheat straw organic fertilizers, and the quality of the crops can be greatly improved by the decomposed wheat straw organic fertilizers.

Description

technical field [0001] The invention relates to the field of microbial bacterial agents, in particular to a wheat straw decomposing agent and a preparation method thereof. Background technique [0002] my country is a large agricultural production country. Although there is a large harvest of grain every year, hundreds of millions of tons of wheat straw are produced at the same time. These huge amounts of straw cause serious social and environmental problems. Burning straw will not only cause air pollution, but also affect people. Random piles of straw will occupy a large amount of land, and straw piles of various sizes will also bring fire hazards. Therefore, how to deal with these huge amounts of straw during the annual summer harvest has become a major problem. [0003] Straw recycling is a traditional Chinese medicine method to solve this problem. Among them, "straw returning to the field" can not only bring economic benefits, but also has important social and environment...
