Microbial selenium-rich medical fertilizer for preventing and treating root-knot nematode disease, clubroot and underground pests

Abstract

The invention provides a microbial selenium-rich medical fertilizer for preventing and treating root-knot nematode disease, clubroot and soil insects. The microbial selenium-rich medical fertilizer comprises purpureocillium lilacinum, bacillus subtilis, trichoderma harzianum, total matrine, abamectin, selenium-enriched yeast, sugar alcohol composite boron, calcium fulvate, amino acid, tea seed cake, cane sugar and turf. The microbial selenium-rich medical fertilizer is prepared from the following steps: uniformly mixing the tea seed cakes and the turf added with 50% of water, uniformly mixingthe mixture with the selenium-enriched yeast and the cane sugar added with 10% of water, stacking and carrying out aerobic fermentation to form a mixture A; turning and crushing the mixture A, sequentially adding the sugar alcohol composite boron, the total matrine, amino acid raw powder and the calcium fulvate, and fully and uniformly stirring to form a mixture B; and adding the bacillus subtilis, the purpureocillium lilacinum, the trichoderma harzianum and the abamectin into the mixture B, and fully and uniformly stirring to obtain the selenium-rich medical fertilizer. The microbial selenium-rich medical fertilizer can prevent and treat the root-knot nematode disease, clubroot and soil insects. The selenium-rich microbial insecticide-fertilizer is suitable for preventing and treating theroot-knot nematode disease, clubroot and soil insects.

Description

technical field [0001] The invention relates to a selenium-enriched medicinal fertilizer for preventing and controlling root-knot nematode, clubroot and underground pest microorganisms in the field of pesticides. Background technique [0002] At present, there are more than 80 kinds of root-knot nematodes reported in the world, which mainly parasitize on more than 20,000 kinds of hosts such as vegetables, fruit trees, economic crops, food crops, ornamental plants and weeds. Clubroot belongs to weak parasitic fungi. It can survive infection in many unfavorable environments, and its vitality is also particularly tenacious, and it can survive in the soil for more than 10 years. [0003] Clubroot and root-knot nematode are two major root diseases that are prominent in the production of crops, especially vegetables. Tumors of different sizes are formed on the roots, resulting in deformed roots, and finally the growth of the aboveground parts is slow, short, water-deficient, and ...
