Abstract

The invention relates to the technical field of soil sample culture, and discloses a soil sample culture device for pesticide toxicity experiments and a method thereof. The culture device comprises a protection box body, a culture device which is arranged in the protection box body and is used for carrying out a soil toxicity test, a feeding module which is used for feeding materials to the culture device, a first feeding mechanism which is connected with the feeding module, a second feeding mechanism which is connected with the feeding module and the culture device, and a control unit which is used for carrying out automatic control, the method comprises the following steps: loading a to-be-detected soil sample and a pesticide reagent into the feeding module; setting multiple groups of experiment parameters through the control unit; and performing a soil culture experiment according to the experiment parameters provided by the control unit until the culture of the soil sample is finished. According to the technical scheme, manual experiment of workers is replaced by the soil sample culture device, so that the working intensity of the workers is reduced, and the culture efficiency of soil culture is improved.

Description

technical field [0001] The invention relates to the technical field of soil sample cultivation, in particular to a soil sample cultivation device and method for pesticide toxicity experiments. Background technique [0002] With the rapid development of agriculture in our country, the hazards of pesticides are gradually revealed; after the application of pesticides, a part of the pesticide is attached to the plant body, or penetrates into the plant and remains, polluting the grain, vegetables, fruits, etc.; the other part is scattered on the soil or evaporates. , Dissipate into the air, or flow into rivers and lakes with rainwater and farmland drainage, polluting water bodies and aquatic organisms. Pesticide residues in agricultural products pass through feed, polluting poultry and livestock products; pesticide residues pass through the atmosphere, water, soil, and food, and finally enter the human body, causing various chronic or acute diseases. [0003] In terms of absorpt...
