The invention firstly proposes that the spirulina polysaccharide and the bacillus amyloliquefaciens preparation are mixed and applied, not only does not produce side effect on the bacillus amyloliquefaciens preparation, but also can effectively improve the prevention and treatment effect on bacterial diseases and increase the yield and income.
Description
Technical Field
The invention relates to the technical field of biological control, in particular to a bacillus amyloliquefaciens preparation and application thereof in controlling bacterial diseases.
Background
Bacterial diseases are diseases caused by bacterial pathogen infection, such as soft rot, ulcer, bacterial wilt and the like. Bacteria which attack plants are bacillary bacteria, most of which have one to several flagella, can invade through natural orifices (stomata, skin pores, water pores, and the like) and wounds, are spread by running water, rainwater, insects, and the like, live through winter in disease residues, seeds, and soil, and are easy to cause diseases under high temperature and high humidity conditions.
The mode of preventing and controlling bacterial diseases still mainly adopts disease-resistant breeding and takes chemical prevention and control as assistance. Wherein breeding is limited due to long period and high input cost; chemical control is quick, cheap and efficient, but the existing effective agents for bacterial diseases mainly comprise: copper preparation, zinc preparation, antibiotics, benziothiazolinone and other few pesticides. But the frequent use of chemical pesticides and the characteristics of quick propagation genetic variation and high fitness of bacteria lead pathogenic bacteria to quickly generate resistance, and influence the control effect of medicaments. The biological control method utilizing the biocontrol bacteria can effectively solve and avoid the resistance problem of the medicament, has high efficiency, no toxicity, no harm, no pollution and no drug resistance, not only meets the requirements of people on green agricultural products, but also provides guarantee for the sustainable development of agriculture, so the research on the biological control of plant bacterial diseases is more and more emphasized.
Bacillus spp is ubiquitous in soil, is one of dominant microbial populations existing in soil and plant micro-ecological systems, has strong capability of resisting external environment pressure due to the generation of endogenous spores, can resist damage caused by drying, heat and ultraviolet radiation in living environments, maintains the self viability unaffected, has very good application prospect due to biological characteristics, and particularly shows strong vitality in biological products using live bacterial preparations. The bacillus has various varieties and huge quantity, can produce various physiologically active substances and metabolites, and has wide industrial application prospect.
Chinese granted patent CN103087951B discloses a strain of Bacillus amyloliquefaciens and application thereof. The strain number of the bacillus amyloliquefaciens is MH71, and the registration number of the bacillus amyloliquefaciens in the common microorganism center of the China Committee for culture Collection of microorganisms is CGMCC No. 6978. Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) MH71 has obvious inhibiting effect on various pathogenic fungi such as botrytis cinerea, fusarium graminearum, brown rot, root rot and anthracnose on fruit and vegetable crops, and pathogenic bacteria such as Chinese cabbage black rot, oyster mushroom brown spot and cucumber angular leaf spot. Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) MH71 has high propagation speed, strong stress resistance and great significance for preventing and treating soil-borne diseases such as cabbage wilt and the like caused by fungi, and can be artificially cultured.
Chinese patent application CN112694998A discloses a Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) ZN-S2 with the preservation number: CGMCCNO: 18962. the application of the Bacillus amyloliquefaciens ZN-S2 is also disclosed: is used for inhibiting the growth of plant pathogenic bacteria, thereby preventing and controlling plant bacterial diseases.
However, with the development of times and the increase of drug resistance, it has been difficult to achieve good effects of bacillus amyloliquefaciens alone for controlling bacterial diseases. Therefore, the skilled person also tries to combine bacillus amyloliquefaciens with other drugs to improve the control effect. Although the prior art mentions that the bacillus amyloliquefaciens preparation can be mixed with other fungicidal pesticides and plant growth regulators for use, the technical problem to be solved by the technical staff in the field is still how to ensure that the mixed preparation has no side effect on bacillus amyloliquefaciens and can improve the control effect.
In earlier researches of the applicant, the spirulina polysaccharide and the bacillus subtilis preparation are mixed and applied, so that the bacillus subtilis preparation cannot generate side effects on the bacillus subtilis preparation, and the prevention and treatment effects on the clubroot of cruciferae and the yield increase can be effectively improved. However, spirulina polysaccharides have no substantial influence on the activity of bacillus amyloliquefaciens, and therefore, the applicant of the present invention further studies on bacillus amyloliquefaciens and finds that spirulina polysaccharides have a significant meaning for improving the activity thereof, and the present invention is achieved based on the finding.
Disclosure of Invention
Based on the background technology, the technical problem to be solved by the invention is to provide a bacillus amyloliquefaciens preparation and an application thereof in preventing and treating bacterial diseases.

the invention relates to an application of a bacillus amyloliquefaciens preparation in preventing and treating bacterial diseases, wherein the bacillus amyloliquefaciens preparation contains bacillus amyloliquefaciens and spirulina polysaccharide. Spirulina polysaccharides (Spirulina polysaccharides) are physiologically active polysaccharides extracted from Spirulina and are nontoxic. Usually colorless or pale yellow powder, soluble in water, insoluble in alcohol and fats. The invention firstly proposes that the spirulina polysaccharide and the bacillus amyloliquefaciens preparation are mixed and applied, so that the side effect on the bacillus amyloliquefaciens preparation can not be generated, the prevention and treatment effect on bacterial diseases can be effectively improved, and the yield and income can be increased.
In a preferred embodiment of the present invention, the weight ratio of bacillus amyloliquefaciens to spirulina polysaccharide is 10: 0.5 to 2; preferably 10: 0.8-1.2. The preparation of the invention is mixed with bacillus amyloliquefaciens and spirulina polysaccharide according to a specific proportion, and is beneficial to improving the prevention and treatment effect.
In a preferred embodiment of the invention, the bacillus amyloliquefaciens strain has the accession number: bacillus amyloliquefaciens strain CICC10081 with content of 16-22 × 108cfu/g formulation.
In another aspect, the invention relates to a formulation for controlling bacterial diseases, said formulation comprising, by weight, 10: 0.5-2 of bacillus amyloliquefaciens and spirulina polysaccharide; the weight ratio is preferably 10: 0.8-1.2. Preferably, the bacterial disease is bacterial blight of rice.
