Problems solved by technology

[0003] The control of crop root diseases often relies on chemical control. The use of fungicides has caused some pathogenic bacteria to develop drug resistance, and the use of fungicides has to be increased, which inevitably causes environmental pollution and pesticide residues in agricultural products.

preparation example Construction

[0026] The preparation method of the microbial inoculum is not particularly limited in the present invention, and it is preferable to mix the various components.

[0027] In the present invention, there is no special limitation on the method of using the microbial inoculant, and root irrigation and flushing are preferred, and the usage amount is preferably 10-30 g / mu, more preferably 15-25 g / mu.

[0028] The present invention also provides the application of the microbial agent described in the above technical solution in the prevention and treatment of crop root diseases. In the present invention, the crop root diseases preferably include capsicum bacterial wilt, strawberry root rot, soybean root rot or cucumber wilt.

Embodiment 1

[0031] 1 part of Pseudomonas fluorescens, 2 parts of Bacillus flexus, 1 part of Bacillus subtilis, 1.5 parts of Lactobacillus plantarum, 4 parts of dibutyl hydroxytoluene and 4 parts of malic acid are uniformly mixed to obtain the microbial bacterial agent. The effective viable count in Pseudomonas fluorescens was 1×10 10 cfu / g, effective viable count in Bacillus flexus is 2×10 9 cfu / g, the effective number of viable bacteria in Bacillus subtilis is 1.5×10 10 cfu / g, the effective number of viable bacteria in Lactobacillus plantarum is 6×10 8 cfu / g.

Embodiment 2

[0033] Mix 5 parts of Pseudomonas fluorescens, 6 parts of Bacillus flexus, 3 parts of Bacillus subtilis, 4.5 parts of Lactobacillus plantarum, 8 parts of tert-butyl hydroquinone and 9 parts of sorbic acid to obtain the microbial agent. The effective viable count in Pseudomonas fluorescens was 1×10 10 cfu / g, effective viable count in Bacillus flexus is 2×10 9 cfu / g, the effective number of viable bacteria in Bacillus subtilis is 1.5×10 10 cfu / g, the effective number of viable bacteria in Lactobacillus plantarum is 6×10 8 cfu / g.

Abstract

The invention provides a microbial agent for preventing and treating crop root system diseases and an application thereof, and belongs to the technical field of microbial preparations. The microbial agent comprises the following components in parts by weight: 1-5 parts of pseudomonas fluorescens, 2-6 parts of bacillus flexus, 1-3 parts of bacillus subtilis, 1.5-4.5 parts of lactobacillus plantarum, 4-8 parts of an antioxidant and 4-9 parts of a stabilizer. The microbial agent can prevent and treat the crop root system diseases, and can prevent and treat pepper bacterial wilt, strawberry root rot, soybean root rot and cucumber fusarium wilt. After the microbial agent provided by the invention is used, the crop root system diseases can be prevented and treated, and the prevention and treatment effects are 85% or above.

Description

technical field [0001] The invention belongs to the technical field of microbial preparations, and in particular relates to a microbial bacterial preparation for preventing and treating crop root diseases and its application. Background technique [0002] Plant disease refers to the phenomenon that plants undergo a series of morphological, physiological and biochemical pathological changes under the influence of biological or abiotic factors, hindering the normal growth and development process, thereby affecting human economic benefits. The process of physiological dysfunction and tissue structure damage of plants under the influence of pathogens or unsuitable environmental conditions. Plant diseases are antagonistic symbiosis between host plants and pathogens, and their occurrence and prevalence are caused by the interaction between host plants and pathogens. result. The occurrence of plant diseases often causes serious losses to the national economy and people's lives. ...
