Disease controlling microbial fertilizer special for tuberous crops and preparation method thereof

Abstract

The invention discloses a disease controlling microbial fertilizer special for tuberous crops and a preparation method thereof, in particular to a microbial fertilizer special for controlling sweet potato black rot and a preparation method thereof. The microbial fertilizer is prepared by mixing of the following raw materials: antimycoin streptomyces powder, wet streptomyces powder, paenibacillus pabuli powder, paenibacillus jamilae powder, and potassium fulvate raw powder. The strains involved in the invention can utilize the antibiosis, competition, hyperparasitism and bacteriolysis effects between or within microbial species, or utilize secondary metabolites to induce disease resistance of sweet potatoes, and can produce a variety of antibiotics like endomycin compound, non-polyene antifungal antibiotics, dihydrostreptomycin, humidin and cobalamin to inhibit sweet potato black rot pathogenic bacteria and strengthen the disease prevention effect. The microbial fertilizer provided by the invention is safe to human and livestock, and is environment-friendly. Application of the microbial fertilizer provided by the invention to control of sweet potato black rot is not easy to produce drug resistance. The microbial fertilizer has the advantages of simple preparation method, low cost and easy use.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a potato special microbial fertilizer for preventing and controlling diseases and a preparation method thereof. Background technique [0002] Sweet potato is a high-yield, stable, nutritious and versatile crop. It is not only an important food crop, but also a good feed crop and an industrial raw material crop. In recent years, the nutritional and health effects of sweet potato have been deeply studied at home and abroad. As a new type of nutritional and health functional food, it has increasingly attracted people's attention. Sweet potato is pollution-free and pollution-free in the process of production and storage. Relevant experts commented that it is "the most ideal food in the 21st century". The proportion of sweet potato food in human food structure will become larger and larger, and its influence will become more Extensive, the industrialization ...

AI Technical Summary

Problems solved by technology

The selection of disease-resistant varieties is the most economical, effective, safe and convenient control method. However, due to the difficulty in breeding sweet potato disease resistance, a sweet potato with high yield, high quality, and good disease resistance (and resistance to multiple diseases) has been bred. Sweet potato varieties are not easy; physical control and agricultural control measures take a long time, are slow to take effect, and time-consuming; soil degradation caused by chemical pesticides, pesticide residues, pollution of water sources and the environment, disruption of biological chains, ecological imbalance, and disease occurrence A series of problems such as resistance have become increasingly prominent

The method of biological control has received more and more attention, but there is no relevant invention that combines the control of sweet potato diseases with fertilizers to be disclosed
