The invention relates to a method for identifying a soil poisonous gas by water dropwort, and belongs to the technical field of soil poisonous gas detection. The method is characterized by comprising the following steps: (1) preparing water dropwort seeds, namely preparing a water dropwort seed carrier, and putting water dropwort seeds onto the wet carrier; (2) sampling soil, namely putting a to-be-detected soil sample into a sealing appliance; and (3) detecting in a sealed condition, namely putting the wet carrier carrying the water dropwort seeds on the sealing appliance, keeping a distance from soil, and detecting the soil poisonous gas according to the growing situation of the water dropwort seeds after sealing. The method has the advantages of simplicity in operation, convenience in detection, accurate result, low cost, remarkable effect, wide application range and the like, is safe and environment-friendly, and especially has a remarkable effect for detecting the soil remained with dazomet.
Description
technical field [0001] The invention belongs to the technical field of soil poisonous gas detection, in particular to a method for soil poisonous gas detection. Background technique [0002] At present, soil toxic gas detection usually uses chemical testing methods for toxic and harmful gas detection. The detection process requires various chemical reagents and advanced equipment. The existing chemical reagent detection methods have disadvantages such as complex procedures, high detection cost, difficult operation, chemical pollution, high requirements for detection personnel, and unsuitable for popularization and application. These deficiencies have affected the enthusiasm for soil testing and scientific planting, causing a series of problems in plant growth and scientific management. Contents of the invention [0003] The invention provides a method for identifying soil poisonous gas by cress in order to solve the technical problems in the known technology. [0004] T...
