Beauveria bassiana biological compound medicine fertilizer and preparation method thereof

Abstract

The invention provides a beauveria bassiana biological compound medicine fertilizer and a preparation method thereof and relates to the technical field of biological medicine fertilizers. The method comprises the following steps: uniformly stirring 60-80 parts of culture medium and 20-43 parts of assistant carbon source and adding water, and adjusting the water content of the mixture to 35-45wt%; transferring the water-containing mixture to a solid fermentation tank, fermenting under a ventilating environment at 20-35 DEG C, overturning once every 26-32 hours and fermenting for 9-11 days; after drying the fermented mixture at 50-80 DEG C, crushing, inspecting quality and granulating to obtain a granular fertilizer; inoculating the separated and purified beauveria bassiana and conidia to the prepared granular fertilizer and using the granular fertilizer as a solid fermentation culture medium to obtain the beauveria bassiana biological compound medicine fertilizer. According to the fertilizer provided by the invention, the use level of chemical pesticides is reduced, the quality of crops is enhanced and improved and the environmental pollution is reduced while the fertility of soil is improved.

Description

Technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a biological compound fertilizer of Beauveria bassiana and a preparation method thereof. Background technique [0002] In traditional agriculture, in order to increase crop production and income, farmers often use a large amount of chemical fertilizers and production hormones to promote crop growth. At the same time, pesticides are also used to control crop diseases and insect pests. However, these fertilizers, pesticides and production hormones are almost all Used in the same period, the xylene and other auxiliary additives have been left many times, resulting in the imbalance of soil structure, land fertility and plant ecology, degradation and abnormal changes, resulting in persistent diseases of crops, especially vegetables, fruits and vegetables, and these diseases should be treated The chemical pesticides used have further increased the pollution of land and crops....

Problems solved by technology

[0002] In traditional agriculture, in order to increase crop production and income, farmers often use a large amount of chemical fertilizers and production hormones to promote crop growth, and also use pesticides to control crop diseases and insect pests. However, these chemical fertilizers, pesticides and production hormones are almost all When used in the same period, auxiliary additives such as xylene remain for many times, resulting in soil structure, land fertility and plant ecological imbalance, degradation and mutation, causing stubborn diseases of crops, especially vegetables, fruits and vegetables, etc., and these diseases are treated The chemical pesticides used further increase the pollution of the land and crops
