Embodiment 1

[0018] Embodiment 1: the B.t biopesticide prepared by solid-state fermentation method is graded with the method of the present invention:

[0019] Its concrete process steps are:

[0020] 1) Coarse pulverization: Coarse pulverization of the B.t biological pesticide prepared by the solid-state fermentation method with an ordinary hammer mill (power 2 kilowatts);

[0021] 2) Classification: Sieve and classify the coarsely crushed B.t biopesticide with an electric grading sieve with a 40-mesh standard sieve to obtain B.t biopesticide fine powder greater than 40 mesh and B.t biopesticide coarse powder less than 40 mesh;

[0022] 3) Supersonic crushing:

[0023] Supersonic pulverization of the B.t biopesticide fine powder greater than 40 mesh and the B.t biopesticide coarse powder less than 40 mesh prepared in step 2, to obtain B.t biopesticide products with a toxicity potency of 20000IU / mg and 12000IU / mg;

[0024] The supersonic airflow pulverization is: placing the B.t biopesti...

Abstract

The invention relates to a method for grading B.t biopesticides prepared by a solid-state fermentation method. The method is characterized in that: B.t biopesticides are first coarsely crushed, then sieved and classified into fine powders larger than 20-80 mesh and coarse powders smaller than 20-80 mesh, and then separately The coarse powder and fine powder are subjected to supersonic airflow crushing to obtain B.t biopesticide products with toxicity potency of 16000-32000IU / mg and 8000-16000IU / mg respectively, which fully comply with the industry standard of the Ministry of Agriculture (NY-293- 95), to meet the needs of different markets at home and abroad.

Description

field of invention [0001] The invention relates to a post-treatment method of biological pesticides in the technical field of microorganisms, in particular to a method for grading Bacillus thuringiensis biological pesticides prepared by a solid-state fermentation method. Background technique [0002] At present, at home and abroad, the fermentation technology that can achieve strict large-scale purebred cultivation is still liquid submerged fermentation technology, and the fermentation of Bacillus thuringiensis is no exception. Among modern microbial pesticides, Bacillus thuringiensis biopesticides (hereinafter referred to as B.t biopesticides) prepared by fermentation are currently the most productive microbial pesticides in the world. The industrial production of B.T biological pesticides in my country also adopts liquid submerged fermentation technology. In use, in order to reduce production costs, mostly directly use its fermented liquid to mak...
