Problems solved by technology

In recent years, due to the increase of multiple cropping index and continuous cropping, these soil-borne diseases have become more and more serious. For example, pepper root rot and cotton wilt have seriously affected the increase in yield and economic benefits.
The use of biological pesticide control is one of the important measures, but the cost of pesticide production is high and it is inconvenient to use
The production of organic fertilizers with biological control effects can overcome the above-mentioned defects, and there is no such product publicly reported so far

Embodiment 1

[0053] (1) Preparation of decomposed organic matter:

[0054] In terms of parts by mass, 50 parts of furfural slag crushed to 20 meshes, 30 parts of soot residue, 19 parts of weathered coal, and 1 part of EM composite bacterial agent were fully mixed and uniform. Adjust the moisture content of the mixture to be 60%, C / N to be 25, and pH to be 7.5. Pile the mixture into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, 8 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 4 days. Turn over the pile, and ferment for another 3 days when the pile temperature rises above 50°C. Dry the moisture content of the above-mentioned fermented organic fertilizer to 30% for subsequent use.

[0055] (2) Preparation of Trichoderma inoculum:

[0056] Preparation of cottonseed hull compost: 92 parts of cottonseed hulls, 2 parts of potassium dihydroge...

Embodiment 2

[0065] (1) Preparation of decomposed organic matter:

[0066] In terms of parts by mass, 60 parts of furfural slag, 25 parts of smoke residue, 13 parts of weathered coal, and 2 parts of EM composite bacterial agent are fully mixed and uniform. Adjust the moisture content of the mixture to be 65%, C / N to be 28, and pH to be 7. Pile the mixture into a trapezoidal pile with a height of 2.0 meters, punch holes from the top down, 12 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 5 days. Turn over the pile, and ferment for another 2 days when the pile temperature rises above 50°C. Dry the moisture content of the above-mentioned fermented organic matter to 25% for subsequent use.

[0067] (2) Preparation of Trichoderma inoculum:

[0068] Preparation of cottonseed hull compost: 95 parts of cottonseed hulls, 1 part of potassium dihydrogen phosphate, 2 parts of su...

Embodiment 3

[0074] Trichoderma inoculum, actinomycetes fermented liquid, organic matter decomposing preparation method are identical with embodiment 1, difference is:

[0075] Organic matter fermentation raw materials are 55 parts of furfural slag, 35 parts of soot residue, 9 parts of weathered coal, and 1 part of EM compound bacterial agent; the formula of biological disease prevention organic fertilizer is 80 parts of decomposed organic matter, 15 parts of Trichoderma bacterial agent, actinomycete fermentation broth 10 servings.

[0076] This fertilizer is suitable for soils with moderate disease.

Abstract

The invention relates to a biological disease-preventing organic fertilizer and a preparation method thereof. The components in part by mass of raw materials of the fertilizer are: 65 to 85 parts of decomposed organic substances, 5 to 15 parts of trichoderma bacterial agents, 5 to 15 parts of actinomycetes fermentation broth, wherein the decomposed organic substances are obtained by taking 45 to 65 parts of furfural residue, 20 to 35 parts of cigarette residue and 8 to 20 parts of weathered coal as raw materials, adding 1 to 2 parts of microbial fermentation bacterial agents for stacking fermentation and airing the obtained product till the moisture content is between 25 and 35 percent. The biological disease-preventing organic fertilizer has the advantages of good disease-preventing effect, safety, environment-protecting property and low cost.

Description

technical field [0001] The invention relates to a disease-preventing organic fertilizer produced by using biocontrol Trichoderma, actinomycetes and decomposed organic matter as main raw materials and a preparation method thereof, belonging to the technical field of organic fertilizer production. Background technique [0002] Plant disease is one of the main factors affecting agricultural production. At present, the application of chemical pesticides is still the main measure to prevent and control plant diseases. However, chemical pesticides are likely to cause residual pollution, induce pathogen resistance, and harm non-target organisms. In the process of seeking safe and effective control measures, the biological control of plant diseases has attracted more and more attention. Biological control will become an important measure to control plant diseases, protect the ecological environment of farmland, and produce pollution-free agricultural products. [0003] Trichoderma ...
