Abstract

The invention relates to agricultural machinery appliances, and particularly relates to a soil sterilization and disinfestation device. The technical scheme is that the light condensation heating type solar energy soil sterilization and disinfestation device comprises a soil conveying component and a soil heating component. According to the invention, pests, pathogenic bacteria and weed seeds in the soil are killed by utilizing high temperature and high light generated by solar energy light condensation and heat collection technologies, and fossil energy is not required to be consumed. Compared with an existing chemical killing method, the device provided by the invention almost has no pollution for the environment and protects the agricultural food safety. The soil in a glass vacuum tube is stirred and heated, organic pollutants in the soil are enabled to be effectively volatized, the polluted soil is restored in the sterilization and disinfestation process, and the self cleaning capacity of the soil is improved. Back heating of the high-temperature soil is realized through heat exchange between the processed high-temperature soil and feeding soil, and the solar energy utilization efficiency of the soil sterilization and disinfestation device is improved.

Description

technical field [0001] The invention relates to an agricultural machinery appliance, in particular to a soil sterilization and insecticide device. Background technique [0002] At present, facility agriculture can increase crop production several times or even dozens of times that of traditional farmland, so it has been rapidly popularized. However, the internal temperature and humidity of facility agriculture are high, the light is weak, the air flow is slow, the crops grow vigorously and the buds are tender, and are vulnerable to diseases and insect pests. Therefore, sterilization and insecticide are important links in the daily management of facility agriculture. At present, the commonly used method of sterilization and insecticide is to apply highly toxic pesticides to the planting soil. The use of this method of insecticide and sterilization all year round will cause the pests to develop drug resistance, and at the same time increase the pollution of the soil, increasin...
