Production process for potato bacterial wilt resistant compound microbial agent

Abstract

The invention provides a production process for a potato bacterial wilt resistant compound microbial agent. Fertilizer comprises the raw materials of 15-20 parts of bacillus mucilaginosus, 15-20 parts of trichoderma harzianum, 15-20 parts of streptomyces microflavus, 10-35 parts of chitosan oligosaccharide, 10-15 parts of vegetable oil sludge and 10-15 parts of plant ash. By adopting the production process of bacterium preparation, dosing, compound bacterium pelletizing, first-layer vegetable oil sludge adhesive-smearing, second-time plant ash adhesive-smearing and third-time chitosan oligosaccharide adhesive-smearing, the three probiotics are combined together and meanwhile separated from the antibacterial component, namely, the chitosan oligosaccharide, so that the respective effects are given to play to the maximum extent. Through the antagonism effect and the killing effect of microorganisms on bacterial wilt bacteria, and induced resistance of the chitosan oligosaccharide to potatoes, potato bacterial wilt is prevented and treated; and the advantages of non-pollution, environmental friendliness, low cost and lasting effect are achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a production process of a compound microbial agent for resisting potato bacterial wilt. Background technique [0002] Potato, potato (scientific name: Solanum tuberosum L.), belongs to the perennial herbaceous plant of Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, potatos, etc., the tubers of Solanaceae plants. Together with wheat, rice, corn, and sorghum, it has become the world's top five crops, with a large amount of daily planting. Potato bacterial wilt is caused by bacteria and is a bacterial vascular tissue disease. The leaves show that the new leaves on the top are initially wilting and drooping, and then the lower leaves develop and wither, and then the middle leaves wither. At the initial stage of the disease, ...

Problems solved by technology

[0005] The research of preventing and treating potato bacterial wilt has a certain history, such as patent application No. 201010608565.X, an antagonistic bacteria and microbial organic fertilizer that can control potato green potato bacterial wilt, adopts the independent antagonistic bacteria (BacillussubtilisI-23) to add To organic fertilizers, and add nitrogen, phosphorus and potassium nutrients to make bio-organic fertilizers to prevent potato bacterial wilt; another example is the traditional Chinese medicine composition disclosed in Application No. 201310580772.2, a method of using disease-resistant drugs for potato bacterial wilt. The anti-disease drugs used in this field have caused a certain degree of waste of traditional Chinese medicine resources; another example is the application number 201510132194.5, a disease-resistant drug for potato bacterial wilt, which discloses a disease-resistant formula using licorice, tangerine peel, pepper and formalin. The method is simple, but the effect is not obvious

In addition to adding antagonistic bacteria to fertilizers, the above patents do not add chitosan oligosaccharides, a beneficial ingredient that can improve potato resistance, and without production treatments such as sticking and coating, they cannot achieve long-term disease resistance. Invention can solve this problem well
