Microbial organic fertilizer for preventing and controlling strawberry red core disease, and production method thereof

Abstract

The invention discloses a microbial organic fertilizer for preventing and controlling strawberry red core disease, and a production method thereof. The method comprises the following steps: respectively processing Streptomyces shandongensis sp.nov and Bacillus thermoamylovorans to prepare a primary seed liquid and a secondary seed liquid, carrying out fermentation culture, mixing the above fermentation cultured bacterial liquids according to a (1-3):(5-10), adding the obtained bacterial liquid mixture to organic matters obtained after primary compost fermentation of manure and mushroom residues, and re-fermenting the obtained material, wherein the addition amount of the bacterial liquid mixture is 10-20%; and carrying out low temperature drying on the re-fermented culture to obtain the microbial organic fertilizer. No antagonistic action exists between microbial strains selected by the microbial organic fertilizer, and all strains and metabolites thereof have synergism, can commonly inhibit propagation of plant pathogens to realize pest disease prevention and control effects, especially have substantial prevention and control effects on the strawberry red core disease, are fast effective, and generate no drug resistance.

Description

technical field [0001] The invention relates to a microbial organic fertilizer for preventing and treating strawberry red column disease and a production method thereof. Background technique [0002] Strawberry root rot in solar greenhouse (also known as red heart disease, red heart root rot, brown heart disease) is a root disease that has occurred on a large scale in greenhouse strawberry production in recent years. In Hebei, Liaoning, Shandong and other main strawberry planting areas, the damage is serious, and there are two common types: acute type and chronic type. The acute type usually occurs in spring and summer. After the rain, the tip of the leaves suddenly withers, and soon becomes green and withered, causing the whole plant to die quickly. The chronic type can occur after colonization to the beginning of winter. The margins of the lower old leaves turn purple red or purple brown, gradually expand upward, and the whole plant wilts or dies. The occurrence of straw...

Problems solved by technology

[0004] At present, chemical control is mainly used for the prevention and treatment of strawberry red column disease, but the chemical control agent used for chemical control has a short duration and many application times. If the chemical control agent is used for a long time, the bacteria will easily develop resistance to it, and the control effect will be reduced. It will increase the pesticide residues in the fruit and affect food safety
