Method for killing soil bacteria and insects and improving soil and special device for killing bacteria and insects

Abstract

The invention discloses a method for killing soil bacteria and insects and improving soil and a special device for killing bacteria and insects, wherein the method for killing soil bacteria and insects and improving soil comprises the following steps: first, rotatably plowing the surface soil, where the rotary plowing depth is not less than 35 cm; second, shoveling the surface soil from the land, and lifting the shoveled surface soil and then baking the surface soil by flame; and third, complementing microorganism, compost and trace element; the special device comprises a box, wherein a shoveling plate is arranged in the front of the box body; a soil inlet is arranged on the front wall of the box body; a transmission shaft is arranged above the back of the shoveling plate; soil-lifting blades are distributed on the transmission shaft annularly; a first tilting plate is arranged on the middle lower part of the box body; a gas pipe is arranged at the top of the box body; and a flame stove is arranged on the box body. When the special device and the method disclosed by the invention are used for killing bacteria and insects, the cost is low, the insect-killing effect is good and the organic activity and microorganism activity in the soil are ensured.

Description

technical field [0001] The invention relates to a method for killing soil fungi and insects, improving soil and special equipment for killing fungi and insects. Background technique [0002] At present, most rural areas adopt film-covered cultivation or switch to greenhouse cultivation, and greenhouse vegetables have become mainstream products in the market. When mulching planting or changing to greenhouse planting, the suitable environment will make the bacteria and insects in the soil multiply and grow rapidly. In order to eliminate the harmful bacteria and insects in the soil, most people use chemical pesticides to kill the soil before planting crops. Pesticides contain harmful substances, which will remain in the growing vegetables. Long-term consumption of products with pesticide residues will seriously endanger human health and fundamental interests. Because some pests, especially root nematodes, have a particularly strong ability to grow in adversity, and their repro...

Problems solved by technology

When sterilizing and killing insects on a piece of land, a long lighting line is required to drive the insect killing vehicle back and forth with the tractor, so there is a great potential safety hazard, and the operator needs to install pulleys and other devices on the top of the greenhouse. Complicated and expensive; if the generator is installed on the tractor, since the electric heating device needs to work continuously with electricity, the power of the generator is required to be large, and the tractor also needs power to drive the insecticide vehicle forward and the rotary blade to rotate, and the tractor cannot The generator carrying such a large power cannot be popularized and used in a large area

In the Chinese invention patent application with the patent number 201010129662.0, a soil insecticide is disclosed, which includes a box body and a flame nozzle installed on the box body. The cylinder and the reaming dragon installed in the conveying cylinder, multiple conveying cylinders arranged side by side and the reaming dragon in the conveying cylinder spin up the 30cm thick surface soil from the ground, and then bake the swirled soil through the flame nozzle, Since the depth of the conveying cylinder and the hinge dragon extending into the soil is about 30cm, the soil insecticide adopting this structure needs to be driven by a large-horsepower tractor during use, and when the conveying cylinder is driven forward by the tractor, the conveying cylinder and the hinge The dragon is overwhelmed, easily broken by impact, and has a short service life
