Problems solved by technology
[0009] In the prior art, the diagnostic test of soil toxicity is generally carried out by using the artificial climate box device for detection and analysis. The artificial climate box device has the disadvantages of expensive equipment, low ventilation efficiency or inability to completely discharge toxic and harmful gases, too narrow test space, and invertebrate soil. Disadvantages such as the phenomenon of escape are prone to occur during animal breeding and testing

The invention relates to the technical field of soil ecology, specifically a device for testing the toxicity of soil organisms to polluted soil, including a box body, the box body includes a treatment room and a cultivation room, and the treatment room includes a humidification air duct and a drying air duct. Both the drying air duct and the humidifying air duct are connected to the cultivation chamber, the side wall of the cultivation chamber is provided with observation glass, and at least three sets of partitions are arranged alternately in the cultivation chamber, and the upper ends of the partitions are slidingly connected with a cultivation The top of the culture box is provided with a top plate, the surface of the top plate is provided with a ventilation net, the top plate is fixedly connected to the inner wall of the box, and the inside of the treatment chamber is also It is equipped with a honeycomb runner; the cultivation box can collect soil, and cultivate soil organisms in the cultivation box to evaluate the soil toxicity. It is easy to operate and low in cost. With the function of water permeability, the treatment room can adjust the air humidity in the cultivation room.
Description
technical field [0001] The invention relates to the technical field of soil ecology, in particular to a device for testing the toxicity of soil organisms to polluted soil. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3, 4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition products will gradually accum...
