Special mixed-strain microbial fertilizer for onobrychis viciifolia and preparation method thereof

Abstract

The invention relates to special mixed-strain microbial fertilizer for onobrychis viciifolia and a preparation method thereof, and belongs to the technical field of agricultural fertilizer. The fertilizer is prepared from charcoal powder, flower cultivating earth, rotten cattle excrement, straw powder, potassium fulvate, rare earth, onobrychis-viciaefolia nitragin, bacillus mycoides fermentation broth, pseudomonas fermentation broth and bacillus subtilis fermentation broth. In addition, the invention also relates to the preparation method of the fertilizer. The preparation method comprises thefollowing steps of preparing a carrier, crushing, sieving, uniformly mixing and sterilizing raw materials; culturing bacterial broth and inoculating on the carrier. The mixed-strain microbial fertilizer has the effects of being capable of providing comprehensive, balanced and easily-absorbed nutrients for the onobrychis viciifolia, preventing the generation of a soil-borne disease on the onobrychis viciifolia, regulating the pH (Potential of Hydrogen) of soil, increasing the fertility of the soil and avoiding an environmental problem caused by the abuse of chemical fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special mixed strain microbial fertilizer for red bean grass and a preparation method thereof. Background technique [0002] Red bean grass (Onobrychis viciaefolia Scop) is a perennial herbaceous plant belonging to the family Fabaceae, also known as donkey hi bean and donkey bean. It is a very important forage grass and green manure dual-purpose crop. It has high feed value, comparable to alfalfa, and it has bright colors and high ornamental value, so it has the reputation of "grass queen". Red bean grass has a well-developed root system, strong main root and abundant lateral roots. It has high absorption and utilization efficiency of nutrients and water in the soil. It has very outstanding environmental adaptability and is very resistant to adverse factors such as drought, cold, early frost, and late autumn precipitation. Receptivity (Jin Juhe, 1982). In add...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of existing technologies both at home and abroad, excessive reliance on chemical fertilizers in the planting of red bean grass leads to reduced use efficiency of chemical fertilizers, incomplete and balanced nutrient absorption, difficulty in effective prevention and control of soil-borne diseases, and the current situation of ecological environmental pollution problems. The present invention screens out excellent The growth-promoting strain, according to the growth and fertilizer requirements of red bean grass, develops a special compound microbial fertilizer for red bean grass with a certain ratio, provides a new type of "environmentally friendly" mixed strain microbial fertilizer for red bean grass production, explores, excavates and utilizes new Microbial resources are used to prepare fertilizers, improve the nutrient absorption rate of red bean grass, enhance disease prevention capabilities, and replace part of industrial chemical fertilizers, while preventing soil-borne diseases from invading red bean grass, reducing the use of chemical fertilizers, pesticides and farmers' purchasing inputs , so as to save energy and protect the environment
