Alpine grassland pasture endogenous serratia plymuthica strain GH010 and application thereof as well as microbial agent prepared from same and preparation method

Abstract

The invention discloses an alpine grassland pasture endogenous serratia plymuthica strain GH010 capable of inhibiting various pathogenic bacteria and discloses a microbial agent prepared from the alpine grassland pasture endogenous serratia plymuthica strain GH010 and a preparation method thereof. The alpine grassland pasture endogenous serratia plymuthica strain GH010 and the microbial agent prepared from the same disclosed by the invention have the beneficial effects of having good inhibition effects on the various pathogenic bacteria; the inhibition effect is 67.5% of chili rhizoctonia solani and 69.5% of rape sclerotinia sclerotiorum; the bacteriostasis rates of cotton rhizoctonia solani, eggplant sclerotinia sclerotiorum, tomato botrytis cinerea, fusarium wilt of cucumber, exserohilum turcicum, bipolaris maydis or bipolaristriticola are more than or equal to 57.5%; and the strain has growth-promoting effects on crops including alfalfa and the like, and the environmental protection properties of a microbial pesticide and a microbial fertilizer prepared from the strain are good, the resistance to drugs is unlikely to generate and the safety is good.

Description

technical field [0001] The invention relates to the field of biological control, in particular to an endophytic Serratia plymuthica strain GH010 in pasture grasses in alpine grasslands, an application thereof, a microbial agent prepared by the same, and a preparation method. Background technique [0002] Chemical fungicides can remain in the environment and agricultural products. In addition, pathogens gradually develop resistance to chemical fungicides, and the amount of pesticides used gradually increases, which increases the residual amount. of poisoning. In my country, the safety of agricultural products has attracted people's attention in recent years, especially the problem of excessive pesticide residues in agricultural products, which seriously affects the physical and mental health of the whole people, and at the same time affects the ecological environment and agricultural trade. [0003] With the improvement of people's living standards and the enhancement of env...
