Embodiment 1

[0022] Example 1 Preparation of solid microbial fertilizer by the functional bacterial agent for controlling root-knot nematodes

[0023] The preparation method of solid microbial fertilizer is as follows:

[0024] (1) 85kg inorganic fertilizer raw materials (urea 20kg, dipotassium hydrogen phosphate 35kg, potassium sulfate 30kg), 0.02kg cytokinin and 1.5kg trace element salt (0.5kgEDTA-zinc, 0.25kg zinc sulfate, 0.5kg heptahydrate sulfuric acid Ferrous, 0.25kg manganese sulfate) are mixed homogeneously, add 3kg water, 70 ℃ granulate in disc granulator and obtain inorganic fertilizer granule;

[0025] (2) Add 0.75kg pH adjuster (sodium hydroxide or sulfuric acid) to 6kg amino acid powder to adjust the pH value of the mixture to 6.0;

[0026] (3) 0.64kg of functional bacterial agents for controlling root-knot nematode (this functional bacterial agent is made up of the mass ratio of nitrogen-fixing bacteria bacterial agent: biocontrol bacterial bacterial agent: activated carbon...

Embodiment 2

[0028] Embodiment 2 prepares liquid microbial fertilizer by the functional bacterial agent of control root-knot nematode

[0029] The preparation steps of liquid microbial fertilizer are as follows:

[0030] Mix 37kg of inorganic fertilizers (10kg of ammonium nitrate, 10kg of potassium dihydrogen phosphate, and 17kg of potassium sulfate), add 20kg of water, stir and grind to form a solution; add 3kg of borax, 2kg of ferrous sulfate, and 2.5kg of EDTA- Zinc, 0.2kg sodium alginate; heating to 75°C, adding 25kg of molasses fermentation waste liquid containing 60% organic matter mass percentage, and reacting for 1.5 hours; the reaction solution was down to normal temperature; adding a pH regulator (sodium hydroxide or sulfuric acid), Adjust the pH of the reaction solution to be 6, slowly add 10kg of functional bacteria agent (the functional bacteria agent is composed of nitrogen-fixing bacteria agent: biocontrol bacteria agent: activated carbon=2:2:1 mass ratio, rhizobia and cymbi...

Abstract

The invention provides a functional microbial agent for preventing and treating root-knot nematodes, which comprises nitrogen-fixing bacterial agent, biocontrol bacterial agent and carrier, and the mass ratio of the nitrogen-fixing bacterial agent, biocontrol bacterial agent and carrier is 1 to 2.5 : 1.5~5:1, the nitrogen-fixing bacterial agent comprises rhizobia and Azotobacter torus, the ratio of the effective number of viable bacteria of the rhizobia to Azotobacter torus is 1~100:1~200, and the biocontrol Bacteria agent comprises Paecilomyces lilacinus, Verticillium chlamydoides, Bacillus subtilis, Bacillus cereus, the effective activity of said Paecilomyces lilacinus, Verticillium chlamydoides, Bacillus subtilis, Bacillus cereus The bacterial count ratio is 1-100:1-100:1-100:1-100, and the effective viable bacterial count of the functional bacterial agent is greater than 200 million / g. The functional bacterial agent in the present invention is applied to fertilizers, which can increase the disease prevention effect of microbial fertilizers, improve its growth-promoting effect, ensure the nutritional supply of microbial fertilizers in the application process, prevent and control root-knot nematodes, and form healthy root nodules. Promote plant growth, improve crop yield and quality.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a functional bacterial agent for controlling root-knot nematodes and its application in fertilizers. Background technique [0002] Root-knot nematodes have caused a reduction in the yields of crops and commercial crops in my country, and have caused great losses to my country's agricultural economy. In the root-knot nematode-infected soil, root-knot nematodes, crops and rhizosphere microorganisms constitute a small ecosystem, indicating that the occurrence of root-knot nematode disease has a very important relationship with rhizosphere microorganisms. As a stubborn soil disease, root-knot nematode directly harms the nutrient absorption of crop roots. Antagonistic microorganisms are an important way of biological control, and the main disease-preventing bacteria have been screened and applied. Among them, there are three main types of soil microorganisms, bacteria, fungi a...
