Usage of integrated soil sterilization and disinfestation device

Abstract

The invention discloses usage of an integrated soil sterilization and disinfestation device, which is characterized by including: starting a speed regulating motor after igniting fuel in a heating furnace; adding the soil not sterilized or disinfested into a sterilization and disinfestation chamber from a feed hopper; using flame in the heating furnace to externally heat a tubular duct; successively killing pathogens and nematodes in soil after interior temperature of the sterilization and disinfestation chamber exceeds 60 DEG C; and discharging the sterilized and disinfested soil from a discharge pipe and exhausting water vapor from an exhaust pipe. The pathogens, the nematodes and seeds of weeds in the soil can be successively killed by using the integrated soil sterilization and disinfestation device, the soil is applicable to cuttage and seeding of flowers, seedlings and vegetables, sprouting ratio of seeds is increased, germinating rate of the weeds is reduced, normal growth and development of the flowers, the seedlings and the vegetables are ensured, and the ecological environment can be protected from pollution. The usage of the integrated soil sterilization and disinfestation device is applicable to sterilization, disinfestation and drying of various types of soil.

Description

technical field [0001] The invention relates to the soil field, in particular to a method for using an integrated 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 repeated cropping, soil quality has deteriorated severely, and many devastating diseases have appeared in large numbers. Severe, ...

Problems solved by technology

[0006] The disadvantages of the above patents are: the flame of the "soil baking device" reverberatory furnace is in direct contact with the soil, which cannot keep the soil evenly baked, and high temperature baking can easily destroy the aggregate structure of the soil and cause soil compaction , affecting plant growth and development
