Biological organic fertilizer for preventing and curing pepper bacterial wilt and preparation method thereof

Abstract

The invention provides a biological organic fertilizer for preventing and curing pepper bacterial wilt and a preparation method thereof, and belongs to the technical field of fertilizers. The biological organic fertilizer is prepared from, by weight, 50-150 grams of loofah sponge, 2-20 grams of yeast for making hard liquor, 10-30 grams of ferment, 10-30 grams of activated biomass, 20-50 grams of nitrogen phosphorus and potassium ternary compound fertilizer and 5-15 grams of non-pathogenic ralstonia solanacearum. The biological organic fertilizer for preventing and curing pepper bacterial wiltand the preparation method thereof have the advantages that the loofah sponge, the yeast for making hard liquor, the ferment and other microorganisms cooperate through carriers to form a symbiotic relationship with peppers, nutrient substances generated by the decomposition of the yeast for making hard liquor and ferment and the colonization of microorganisms improve the absorption efficiency of pepper nutrients, then the non-pathogenic ralstonia solanacearum is utilized to occupy ecological niches of the ralstonia solanacearum, pathogenic bacteria multiplication is effectively inhibited, andthe biological organic fertilizer can be used for improving the pepper quality and increasing the pepper yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a bio-organic fertilizer for preventing and treating pepper bacterial wilt and a preparation method thereof. Background technique [0002] Capsicum 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 Laueria solanaceae are important factors restricting the production of peppers. In order to increase the yield of peppers and prevent pests and diseases of peppers, growers invest a lot of chemical fertilizers and pesticides in the planting process. With the large amount of chemical fertilizers and pesticides Application, while ensuring and increasing crop growth, 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 chemical fertilizer elements...

Soil-borne diseases mainly caused by Laueria solanaceae are important factors restricting the production of peppers. In order to increase the yield of peppers and prevent pests and diseases of peppers, growers invest a lot of chemical fertilizers and pesticides in the planting process. With the large amount of chemical fertilizers and pesticides Application, while ensuring and increasing crop growth, has brought a series of adverse effects to the soil environment and crops, causing the soil to lack organic matter, harden, acidify, weaken adhesion, lose nutrients, and crops cannot fully metabolize fertilizer elements, etc.

In order to reduce the application of chemical fertilizers and pesticides, bio-organic 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, and improve soil physical and chemical properties and biological properties. active, but the existing microbial fertilizers for capsicum are not efficient and have poor water retention

[0003] Chinese Patent No. CN201710289455.3 discloses a special compound microbial fertilizer for capsicum and its preparation method, including organic fertilizer components, inorganic fertilizer components, compound microbial components and chitosan oligosaccharides; using chitosan oligosaccharides to induce plant disease resistance , which is beneficial for peppers to resist powdery mildew, blight, etc. However, chitosan oligosaccharides have broad-spectrum antibacterial activity, which not only inhibits harmful microorganisms to peppers, but also has a certain killing effect on beneficial microorganisms, thus making the soil microbial community structure imbalance Secondly, the antibacterial effect makes it weaken the fermentation of organic fertilizer components to a certain extent, reduces organic matter and nutrients, and cannot completely inhibit and eliminate pathogenic bacteria in feces, causing secondary pollution to crops; 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; another Chinese patent number CN201310097453.6 discloses a layer hen manure organic fertilizer that can prevent pepper blight and pepper anthracnose The production method of the present method uses biological control combination strains-Aspergillus aculeatus and Penicillium dermis to prevent and control pepper blight, which reduces the impact on the soil microbial community structure to a certain extent, but the strains used have single functions and lack the decomposition of microorganisms on organic matter, resulting in fertilizer efficiency. Reduce, reduce the absorption efficiency of peppers to nutrients
