Problems solved by technology

At present, cotton verticillium wilt is one of the most threatening cotton diseases among cotton diseases. It is a soil-borne vascular disease. This disease has spread all over the world's major cotton production areas, causing serious economic losses.
In addition, the long-term use of chemical fertilizers and pesticides will not only cause serious compaction of the soil and affect the yield of cotton, but also cause a decline in cotton quality, thereby affecting the income of cotton farmers
[0005] The use of microorganisms to control plant diseases is one of the most effective control measures for plant diseases, especially soil-borne plant diseases. However, while reducing the use of chemical pesticides, the development of biological fertilizers with the effects of biological pesticides and fertilizers has become an important issue. It is an international trend. Relevant experts at home and abroad have found many strains of microorganisms that have a significant inhibitory effect on cotton Verticillium wilt in their research. However, the combination of antibacterial strains and vegetative strains has developed a multifunctional bacterial fertilizer that is currently on the market. relatively rare

Embodiment 1-1

[0046] 1. Preparation of composite microbial bacterial agent: use peat to press the bacterial liquid after the three strains of biocontrol Bacillus subtilis NCD-2, Bacillus colioids and Bacillus megaterium are individually fermented: press the bacterial liquid with peat: peat=1:4 After adsorption, the solid powder bacterial agent is mixed according to the ratio of 6:2:2. After mixing, the effective number of viable bacteria in the composite bacterial agent reaches 13×10 8 more than one per gram, and the water content should be kept within 30%.

[0047] 2. Sampling. The hydrolysis slag produced in the amino acid production process was obtained from Henan Lianhua Monosodium Glutamate Co., Ltd.;

[0048] 3. pH conditioning: crush the large pieces of hydrolyzed slag into powder or small particles, mix it with powdered lime according to hydrolyzed slag:lime=4:1, pulverize it with a chain crusher and stack it for 8-12 hours to allow it to fully react. Then pulverize after being co...

Embodiment 1-2

[0054] Except for following process, other is the same as embodiment 1-1, makes the biocontrol bio-organic fertilizer produced with amino acid hydrolyzed slag.

[0055] The mixing ratio of hydrolyzed slag and powdered lime is hydrolyzed slag:lime=5:1.

[0056] Biocontrol Bacillus subtilis NCD-2, Bacillus colloid, and Bacillus megaterium are individually fermented with peat for adsorption according to the ratio of bacteria liquid: peat = 1:3, and the solid powder after adsorption After mixing a single bacterial agent, the mixing ratio is 4:3:3, and the effective number of viable bacteria of the compound bacterial agent after mixing reaches 9.5×10 8 More than one per gram, the moisture is kept at 22-25%.

[0057] Ingredients: Slowly add powdery hydrolyzed slag into a mixer, and add the prepared composite microbial bacterial agent in a proportion of 6% by weight.

Embodiment 1-3

[0059] Except for following process, other is the same as embodiment 1-1, makes the biocontrol bio-organic fertilizer produced with amino acid hydrolyzed slag.

[0060] The mixing ratio of hydrolyzed slag and powdered lime is hydrolyzed slag:lime=5:1.

[0061] Biocontrol Bacillus subtilis NCD-2, Bacillus colloid, and Bacillus megaterium are individually fermented with peat for adsorption according to the ratio of bacteria liquid: peat = 1:3, and the solid powder after adsorption After mixing a single bacterial agent, the mixing ratio is 5:2.5:2.5, and the effective number of viable bacteria of the compound microbial agent after mixing reaches 10.5×10 8 More than one per gram, the moisture is kept at 22-25%.

[0062] Ingredients: Slowly add powdered hydrolyzed slag into a mixer, and add the prepared composite microbial bacterial agent in a proportion of 5% by weight.

Abstract

The invention provides a special biological organic fertilizer for verticillium wilt, formed by adsorbing biocontrol bacillus subtilis NCD-2, bacillus mucilaginosus krassilnikov and bacillus megaterium by an adsorbing medium, mixing in a mass ratio of (6 to 4): (3 to 2): (3 to 2) to obtain a compound microbial inoculum, and then mixing with hydrolysis residue. The invention further provides a production method for the biological organic fertilizer. The special biological organic fertilizer for verticillium wilt provided by the invention can remarkably improve the effect of biological fertilizer, has obvious prevention and treatment effects on the diseases of crop, greatly reduces seedling disease rate, as well as can comprehensively provide the nutrients needed by the growth of crop and increase the yield of crop.

Description

technical field [0001] The invention relates to a bio-organic fertilizer and a production method of the bio-organic fertilizer, in particular to a bio-organic fertilizer with biocontrol effect and a production method of the fertilizer. Background technique [0002] Insect pests and diseases of crops are always important factors affecting their yields. The occurrence of pests and diseases can seriously reduce crop yields, or even fail them. Therefore, effective control of pests and diseases is very important. For a long time, my country's agriculture has mainly used chemical pesticides and chemical fungicides to prevent and control pests and diseases. In the past 20 years, the application of chemical pesticides has played an important role in ensuring the safe production of my country's agriculture, but this has led to anti-adjustment and intensive farming. Long-term over-reliance on chemical fertilizers and pesticides has resulted in the waste of a large amount of non-renewab...
