Embodiment 1

[0019] Wheat straw is crushed to less than 15mm, sprayed with bacterial liquid until the moisture content is 75%, and fermented by conventional fermentation bin composting, stacked composting or static composting methods, and the composting starts when the material temperature rises to 50°C. Control the fermentation temperature at 50-70°C, and the temperature of the material starts to drop after 5-15 days. The finished organic fertilizer can be obtained after being properly spread and aired. The material is all black or dark brown, soft and elastic when held by hand, and it is easy to break after drying. Aromatic or fermented.

[0020] The active ingredients of the bacterial agent are Trichoderma viride, Trichoderma aureoviride and Paenibacillus pabuli;

[0021] The colony forming unit number ratio of Trichoderma viride ACCC30166, Trichoderma aureoviride ACCC 32248 and Paenibacillus pabuli ACCC 10273 was 1:1.5:1.8.

Embodiment 2

[0025] Corn stalks are crushed to less than 20mm in size, sprayed with bacteria liquid until the water content reaches 70%, and mixed with a compound microbial agent with a raw material amount of 5wt%, using conventional fermentation bin composting, stack composting or static composting methods. Fermentation, when the temperature of the material reaches 50°C, turn the compost, control the fermentation temperature at 50-70°C, and the temperature of the material begins to drop after 15 days, and then the finished organic fertilizer can be obtained after being properly spread and aired. The material is all black or dark brown, and it is soft to hold Elastic, easily broken when dry, slightly fragrant or fermented.

Abstract

The invention relates to a method for producing a biological organic fertilizer from wheat straw. The method comprises the following steps: crushing the wheat straw to be less than 50mm; spraying a bacterial liquid onto the crushed wheat straw, uniformly mixing, controlling the water content to be within 70-85% and the pH value to be 7; turning over when the temperature of the material is risen to be 50 DEG C, and controlling the fermentation temperature to be 50-70 DEG C and the fermentation time to be 5-15 days; when the compost size of the fertilizer is collapsed by 1 / 3-1 / 2 at the final fermentation point, drying the fertilizer in air, so as to obtain the biological organic fertilizer. As the bacterial liquid is used in biological organic fertilizer fermentation production, the composting time is shortened, the water amount for production is reduced, no toxicity, harm or odor is generated, the environment is not polluted, the nutrients can be maintained, the content of organic matters in the fertilizer is increased, and the quality of the fertilizer is improved.

Description

technical field [0001] The invention relates to a method for producing bio-organic fertilizer, in particular to a method for producing bio-organic fertilizer from wheat straw, which belongs to the field of bio-fertilizer. Background technique [0002] According to reports, the total annual output of various crop straws in my country is more than 700 million tons, including 230 million tons of rice straw and 1 billion tons of wheat straw, accounting for about 30% of the world's total straw. However, these straw resources have not been rationally developed for a long time. Traditionally, straw is used as fuel for farmers or roughage for livestock, and a small amount is used for papermaking. In recent years, due to the sharp decline in the living fuel of farmers, the amount of direct or decomposed straw returning to the field is small, while the amount of direct incineration in the field is large. About 2 / 3 of the country's straw is directly burned every year. Among all stra...
