Synthetic system for killing soil root nematode by heat injection in root position

Abstract

The invention discloses a synthetic system for killing soil root nematode by heat injection in a root position, and the system comprises a carrier, a lifting rocker arm, a programmable logic controller, a steam generator, a steam distribution cabin, a heat injection mechanism and a bearing plate, wherein the lifting rocker arm, the controller and the steam generator are both installed on the carrier; the steam distribution cabin is connected to the lifting rocker arm and connected with the steam generator; the heat injection mechanism is connected between the steam distribution cabin and the bearing plate; the steam distribution cabin is connected with the bearing plate by a spring; the lifting rocker arm and the steam generator are both connected with the programmable logic controller; the steam distribution cabin is provided with a pressure sensor and a steam temperature sensor; a limiting sensor is arranged at the bottom of the steam distribution cabin; a soil temperature sensor is arranged at the bottom of the bearing plate; the limiting sensor, the pressure sensor, the steam temperature sensor and the soil temperature sensor are connected with the controller. The system can be used for effectively killing the root nematodes in the soil at the root position of the soil by means of steam heat injection, and realizing high automation degree and good effect.

Description

technical field [0001] The invention relates to a comprehensive system for treating soil root nematodes through heat injection, and belongs to the technical field of soil root nematodes treatment through heat injection. Background technique [0002] While the vegetable basket is constantly enriched, the problem of "pesticide residues" is also a lingering shadow. Under the current circumstances, there are many effective methods to solve the problem of "pesticide residues", but these methods will greatly increase the cost of vegetables, thereby affecting sales. [0003] The "pesticide residues" of vegetables can be roughly divided into two situations. One is the pesticide residues caused by direct spraying of pesticides on vegetables, and the other is the pesticide residues caused by vegetable plants directly absorbing pesticides from the soil containing pesticide residues. The first situation is easy to attract everyone's attention, and it can be alleviated or eliminated as ...
