Abstract

The invention discloses a method for making an external-heating sterilizing insecticidal device for soil. According to the technical scheme, the method is characterized in that the external-heating sterilizing insecticidal device for soil comprises a cylindrical tube, a flange, a feed hopper, a sterilization and disinfestation chamber, a spiral conveying vane, a center shaft, seal plates, seal rings, a discharge pipe, an exhaust pipe, thermocouples, bearing blocks, a coupling and a variable speed motor. The external-heating sterilizing insecticidal device for soil is used for sterilizing and disinfesting the soil by external heating, flame is not in direct contact with the soil, and accordingly relative stable temperature of the soil can be maintained, the effect of sterilization and disinfestation is improved, loss of effective ingredients of the soil is reduced, production cost is low, efficiency is high, and continuous sterilization and disinfestation are available. By using the external-heating sterilizing insecticidal device for soil, pathogens, nematodes and weed seeds in the soil can be successively killed with no need of pesticides, and accordingly the ecological environment can be protected from pollution. The external-heating sterilizing insecticidal device for soil is suitable for sterilization, disinfestation and drying of the soil.

Description

technical field [0001] The invention relates to the field of soil, in particular to a method for manufacturing an externally heated soil sterilization and insecticide device. Background technique [0002] Generally, the soil used for potting does not need special disinfection and sterilization, as long as it is exposed to sunlight, the effect of disinfection and sterilization can be achieved. However, the soil used for cuttings and sowing should be strictly disinfected and sterilized, because germs are easy to grow from the cuttings. The wound invades the flower and tree, causing the plant to rot and affecting the survival rate. For sowing, the newly born buds have very weak resistance, and microorganisms often cause it to become moldy and reduce the germination rate. [0003] Due to the increase of planting years in protected areas and the widespread existence of double cropping, the soil has seriously deteriorated, and many devastating diseases have appeared in large numbe...
