Embodiment Construction

[0013] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0014] The steel plate makes the oven box body, and fire grate (4) is arranged in the case, and the movable ash hopper (1) that can pull out is arranged in the bottom of fire grate (4). A blower (2) is arranged outside the casing, and a connecting rod (3) connected with the tractor is arranged on the top of the blower (2). There is coal fuel (5) on the top of the grate (4); there is a hot air pipe (7) on the top of the fuel (5). connected. The front side of the diameter of hot-blast pipe (7) is big, and the back side is little. The top of hot blast pipe (7) is provided with thermometer, has some hot blast holes (9) on the lower wall of hot blast pipe (7). High-temperature gas enters the hot gas chamber (8) through the hot air hole (9). The bottom part of the baking oven is connected with a rake, and the rake teeth (10) are arranged on t...

Abstract

The invention discloses a method and equipment for killing bacteria and pests in soil of a greenhouse. The prior method for killing soil bacteria and viruses as well as underground pests by chemical agents fails to achieve ideal sterilizing and disinsectizing effects. The method comprises the following steps: high-temperature gas produced by fuel (5) in a baking oven passes through a hot air pipe (7), a hot air hole (9) and a hot air chamber (8), and enters the soil through rake ditches formed by rake teeth (10) to kill the bacteria and the pests in the soil of the greenhouse. The method has the advantages of killing the bacteria in the soil of the greenhouse and having low pest cost as well as good sterilizing and disinsectizing effects. The equipment has the advantages of simple structure, small volume and convenient operation, and is suitable to be popularized and applied in the greenhouse. The method smartly utilizes the rake ditches formed by operating the rake teeth to ensure that the high-temperature gas evenly enters the soil to combine raking land with sterilization and disinsectization without drilling holes to the soil additionally, thereby saving labor and time, and having good effect at the same time.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection, in particular to a method and equipment for killing soil bacteria and pests in greenhouses. Background technique [0002] Greenhouse is an important infrastructure of modern agriculture, and greenhouse production is an important method of modern agricultural production. People produce vegetables, fruits and other products in various greenhouses to meet the needs of human life. At the same time, various bacteria, viruses and underground pests are produced in the soil of the greenhouse. Bacteria, viruses and underground pests have seriously harmed the production of agricultural products in the greenhouse, reducing the output and quality of agricultural products. Especially with the continuous expansion of vegetable planting in protected areas, soil-borne diseases and insect pests caused by continuous cropping, especially soil root-knot nematodes, are spreading, resulting in ...
