Problems solved by technology

In desperation, they had to use a large amount of pesticides to kill insects. In this way, even if the agricultural products contained pesticide residues, they also destroyed the soil structure.
[0003] Moreover, there is no more effective way to use crop straw. Although returning straw to the field can avoid the harm of burning, it takes a long time to decompose, which brings inconvenience to farming; at the same time, it brings problems such as diseases and insect pests.
Can not fundamentally solve the problem of straw

Embodiment

[0023] A straw biological pesticide, comprising Streptomyces jingyang or Metarhizium anisopliae, is characterized in that: said Streptomyces jingyang or Metarhizium anisopliae is a fermentation culture of a solid medium based on straw, and its weight ratio is

[0024] Streptomyces jingyang or Metarhizium anisopliae: 100%

[0025] 2. The method for preparing straw biopesticide according to claim 1, characterized in that it comprises the following steps:

[0026] a. First crush 100 kg of straw to a powder of less than 2 mm;

[0027] b. Transport the crushed straw to the air explosion chamber, and release it to normal pressure after 3 seconds at a temperature of 150°C and a water vapor environment of 7 atmospheres;

[0028] c. Add 100 kg of water to the gas-exploded stalks and transport them to the high-temperature steam treatment chamber. Sterilize and sterilize for 1.5 hours at a temperature of 110°C and a water vapor environment of 1.5 atmospheres, and use microwave treatment...

Abstract

The present invention relates to biological stalk pesticide and its preparation process. The biological stalk pesticide is prepared through crushing stalk, gas explosion in a gas explosion chamber, adding water in the weight equal to the stalk, sterilizing in a high temperature steam treating chamber, microwave treating, cooling and spraying bacterial seed culture liquid, and solid fermentation in an aerobic fermenter to obtain the biological stalk pesticide. The biological stalk pesticide is used in killing termite, beetles and other pests in soil, and has the advantages of environment friendship, no residue, no pest's resistance, etc.

Description

technical field [0001] The invention relates to a straw biological pesticide and a preparation method thereof. Background technique [0002] my country is a large agricultural country, but various soil pests such as termites and various beetles have always plagued food farmers, cotton farmers, and vegetable farmers. In desperation, a large amount of pesticides have to be used to kill insects. In this way, even if the agricultural products contain pesticide residues, the soil structure is also destroyed. [0003] Moreover, there is no more effective way to use crop straws. Although straw returning to the field can avoid the harm of burning, it takes a long time to decompose, which brings inconvenience to farming and brings problems such as diseases and insect pests. Can not fundamentally solve the problem of straw. Contents of the invention [0004] The purpose of the present invention is to provide a straw biopesticide which can not only kill soil pests, but also prevent...
