Bio-organic fertilizer for preventing and treating pepper phytophthora blight and preparation method of bio-organic fertilizer

Abstract

The invention provides bio-organic fertilizer for preventing and treating pepper phytophthora blight and a preparation method of the bio-organic fertilizer, and belongs to the technical field of fertilizer. The bio-organic fertilizer is prepared from the following raw materials in parts by weight: 50-150g of loofah sponge, 2-20g of yeast, 10-30g of ferment, 10-30g of activated biomass, 20-50g of nitrogen-phosphorous-potassium compound fertilizer and 5-15g of non-pathogenic phytophthora capsici. According to the bio-organic fertilizer provided by the invention, the carrier loofah sponge cooperates with the microorganisms such as the yeast and the ferment to form a symbiotic relationship with pepper; through colonization of the nutrient substances and microorganisms generated by the decomposition of the yeast and the ferment, the absorption efficiency of pepper nutrients is increased; then the non-pathogenic phytophthora capsici occupies the ecological niche of phytophthora capsici, multiplication of the pathogenic bacteria is effectively inhibited. The bio-organic fertilizer provided by the invention can be used for improving the pepper quality and increasing the 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 blight and a preparation method thereof. Background technique [0002] Capsicum is an important economic crop in our country, and it is the main vegetable condiment in daily life. Soil-borne diseases mainly caused by Phytophthora capsici are an important factor 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 extensive 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. In order t...

Soil-borne diseases mainly caused by Phytophthora capsici are an important factor 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 extensive 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, hardening, acidification, adhesion weakening, nutrient loss, 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, improve soil physical and chemical properties and Biological activity, but the existing microbial fertilizers for peppers have low fertilizer efficiency and poor water retention performance

[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
