Embodiment 1

[0024] A disinfection method for preventing and controlling plant diseases and insect pests, characterized in that: Divide purely cultured cotton fusarium wilt fungus cakes into two groups, insert them into sterilized small plastic ziplock bags of 3×4 cm respectively, put the strain bag into soil after sealing; One group was sealed with a 12×24cm large plastic bag and put into human water. When the temperature in the bag reached 55°C, it was maintained for 30 minutes. The second group was left untreated and served as the control group; Inoculated on the culture medium, cultivated in a 22°C incubator, and observed for 30 days; the results showed that the bacteria in the first group did not grow, and the killing rate was 100%, and the bacteria in the second group grew normally.

[0025] The hot water pool is built at the outlet of geothermal water, and pipes are used to introduce one or more strands of geothermal water into the pool; the pool surface is covered with a plastic fil...

Embodiment 2

[0028] A disinfection method for preventing and controlling diseases and insect pests, which is characterized in that: the sclerotia of the purely cultured Coptis chinensis bacteria are divided into two groups, respectively inserted into 3 × 4cm sterilized small plastic ziplock bags, and the small plastic bags are put into the to-be-sterilized organic Then put the organic fertilizer into large plastic bags of 12×24cm respectively. The first group of plastic bags are sealed with a rope and put into human water. When the temperature in the bags reaches 60°C, continue to soak for 20 minutes; The second group of plastic bags were sealed with a rope and left untreated as the control group; after disinfection, the first group of strains were taken out, and the second group was inoculated on the culture medium at the same time, cultured in a 25°C incubator, and observed for 30 days; The results showed that the bacteria in the first group did not grow, and the killing rate was 100%, an...

Embodiment 3

[0031] A disinfection method for preventing and controlling diseases and insect pests, which is characterized in that: the nematode separation liquid is prepared and placed in two sets of finger-shaped tubes respectively, the first set is placed in hot water for treatment, and when the temperature reaches 70°C, continue to soak for 20 minutes; The second group was not treated, and it was the control group; the treated nematode liquid of the first group was taken for microscopic observation, and no nematode activity was seen. The activity of nematodes in the second group was the same as before treatment. Continue to observe the treatment group for 5 days, and there is no nematode activity again, and the killing rate is 100%;

[0032] The truck box is refitted into a multi-layer rack plate as a pool, and the packaged plastic bags are put into the plate; drive to the geothermal water diversion place, and the geothermal water is introduced into the plate for disinfection.

Abstract

The invention provides a disinfection method for preventing and treating the damage caused by diseases and insects. The disinfection method is characterized in that articles are placed in hot water for disinfection. The method can effectively eliminate or restrain pathogenic fungi, bacteria, wireworms and other harmful biological species sources carried in soil matrix, facilities and materials through disinfecting the soil, the facilities, the materials, and the like, and have good effect of preventing and treating the damage by the diseases and the insects without toxic side effect.

Description

technical field [0001] The invention relates to a disinfection method for preventing and controlling pests and diseases. Background technique [0002] The area of ​​protected vegetable land in my country has reached 2 million hectares. With the extension of time, pests and diseases are becoming more and more serious, which affects the yield and quality of crops, and generally causes economic losses of 20-60%. Due to intensive planting, pests and diseases have also become prominent problems in open field cultivation, and diseases can often cause crop yield reduction or even failure. [0003] At present, systemic fungicides such as aldicarb, carbofuran, and methyl bromide are generally used to control plant diseases and insect pests in production. Although these agents have certain effects on plant disease and insect pest control, they will cause a decrease in crop yield and quality, and residual toxicity will also affect People's health; some researchers try to disinfect soi...
