Problems solved by technology

[0002] During the planting process of greenhouse cultivation, different vegetables have different requirements for nutrients, which can easily lead to the lack of nutrients in the soil. At the same time, the accumulation of pathogenic bacteria in the soil of long-term greenhouse cultivation is serious, which can easily lead to the loss of crop yield and quality. decline; and with the large-scale application of pesticides and fertilizers in greenhouse cultivation, the pollution to the environment has gradually increased

Abstract

The invention discloses a preparation method of a growth-promoting germ-killing pest-killing additive for special fertilizers for greenhouse cultivation, comprising the steps: mixing red chili, green Szechuan pepper, garlic, root of hairy Asiabell, nutmeg and medicinal Indian mulberry root, and performing drying, crushing and screening to obtain a material A; mixing well the material A and ethyl alcohol, performing ultrasonic treatment, and performing filtering to obtain filter residue and a material B; subjecting the filter residue to Soxhlet extraction, performing concentrating to obtain a material C, mixing the material B and the material C, and performing drying to obtain an active material; mixing well the active material and modified bentonite, and performing coating to obtain this additive. The obtained additive is effective in eliminating disease and pest damage of greenhouse cultivation soil.

Description

technical field [0001] The invention relates to the technical field of preparation of a special fertilizer additive for greenhouse cultivation, in particular to a preparation method of a special fertilizer additive for growth promotion, sterilization and deinsectization of greenhouse cultivation. Background technique [0002] During the planting process of greenhouse cultivation, different vegetables have different requirements for nutrients, which can easily lead to the lack of nutrients in the soil. At the same time, the accumulation of pathogenic bacteria in the soil of long-term greenhouse cultivation is serious, which can easily lead to the loss of crop yield and quality. decline; and with the large-scale application of pesticides and fertilizers in greenhouse cultivation, the pollution of the environment has gradually increased. How to control agricultural non-point source pollution, while promoting the growth of greenhouse cultivated crops and killing insects in a mor...
