Biological bacterial fertilizer for preventing and treating eggplant root rot and preparation method thereof

Abstract

The invention provides biological bacterial fertilizer for preventing and treating eggplant root rot and a preparation method thereof and belongs to the technical field of fertilizer. The biological bacterial fertilizer comprises 50-150 g of loofah sponge, 2-20 g of refined yeast, 10-30 g of a ferment, 10-30g of activated biomass, 20-50 g of N-P-K compound fertilizer and 5-15 g of non-pathogenic Fusarium solani. Through cooperation of a carrier loofah sponge, refined yeast and ferment, commensalism with the eggplant is formed. The nutrients produced by the decomposition of refined yeast and ferment and colonization of microorganisms improve the nutrient absorption efficiency of the eggplant. The non-pathogenic Fusarium solani occupies the ecological niche of Fusarium solani spores so thatthe proliferation of pathogenic bacteria is effectively inhibited. The biological bacterial fertilizer improves the eggplant quality and the eggplant yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological bacterial fertilizer for preventing and treating eggplant root rot and a preparation method thereof. Background technique [0002] Eggplant is an important economic crop in my country, and it is the main vegetable and condiment in daily life. Soil-borne diseases mainly caused by Fusarium solani are important factors restricting eggplant production. In order to increase eggplant yield and prevent pests and diseases, growers invest a lot of chemical fertilizers and pesticides in the planting process. With the large-scale application of chemical fertilizers and pesticides, in While ensuring and increasing crop growth, it has brought a series of adverse effects on the soil environment and crops, causing the soil to lack organic matter, harden, acidify, weaken adhesion, lose nutrients, and crops cannot completely metabolize fertilizer elements, etc. In order to reduc...

Soil-borne diseases mainly caused by Fusarium solani are important factors restricting eggplant production. In order to increase eggplant yield and prevent pests and diseases, growers invest a lot of chemical fertilizers and pesticides in the planting process. With the large-scale application of chemical fertilizers and pesticides, in While ensuring and increasing crop growth, it has brought a series of adverse effects on the soil environment and crops, making the soil lack of organic matter, compaction, acidification, weakened adhesion, nutrient loss, crops cannot fully metabolize fertilizer elements, etc.

In order to reduce the amount of chemical fertilizers and pesticides used, biological bacterial fertilizers have been developed. Specific microorganisms and plant-derived components are added to organic fertilizers to form new, efficient and safe microbial-organic fertilizers, which are rich in a large number of beneficial substances, including: A variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium can not only provide nutrients for crops, but also have a long fertilizer effect, which can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and Biological activity, but the existing microbial fertilizers for eggplant have low fertilizer efficiency and poor water retention performance

[0003] Chinese Patent No. CN201710337309.3 discloses a production process of an anti-blanket bacterial wilt complex microbial agent, including Bacillus colioids, Trichoderma harzianum, Streptomyces luteus, oligochitosan, plant oil sludge plant ash; using oligochitosan Induce the disease resistance of plants and enhance the stress resistance of plants. However, oligochitosan has broad-spectrum antibacterial activity, which not only inhibits the microorganisms harmful to eggplant, but also has a certain killing effect on beneficial microorganisms, so that the soil microbial community Structural imbalance; secondly, the use of biological control combination strains - Bacillus coliformis, Trichoderma harzianum, and Streptomyces luteus to control bacterial wilt has reduced the impact on the soil microbial community structure to a certain extent, but the strains used have single functions and lack microbial control. The decomposition of organic matter leads to the reduction of fertilizer efficiency and the absorption efficiency of eggplant to nutrients; moreover, in the actual production process, the loss of microorganisms is relatively large, it is not easy to preserve, and the content of effective bacteria is too low, so that the effect of fattening and disease resistance is limited
