The invention relates to the technical field of soil sample cultivation, and discloses a soil sample cultivation device and method for pesticide toxicity experiments; the cultivation device includes: a protection box, a cultivation device for soil toxicity tests arranged inside the protection box, and provided to the A feeding module for feeding the culture device, a first feeding mechanism connected to the feeding module, a second feeding mechanism connecting the feeding module and the culture device, and a control unit for automatic control; the method includes: feeding the feeding module Built-in soil samples and pesticide reagents that need to be tested; set multiple sets of experimental parameters through the control unit; carry out soil cultivation experiments according to the experimental parameters provided by the control unit until the soil sample cultivation is completed; this technical solution replaces the staff's manual operation with a soil sample cultivation device. Conduct experiments to reduce the work intensity of the staff and improve the cultivation efficiency of soil cultivation.
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...
