Abstract

The present invention is fast soil health quality diagnosing method and test device. Specifically, one water maintaining and air permeable tank is separated with a watertight partitioning board intotwo chambers filled with water saturated fine quartzite; one other earthworm escaping tank separated with a watertight partitioning board into two chambers filled with clean soil and polluted soil separately is set on the first tank with the two partitioning boards are aligned vertically; the upper tank is maintained in the moisture level the same as that in field while the lower tank is maintained in water saturation state; earthworms are set to the two chambers in the upper tank; and after earthworms go into soil, the device is set in rest lighted place at 15-25 deg.c. The present invention is simple, and has high sensitivity in detecting the sensitivity of soil animal to the pollution degree of soil.

Description

technical field

[0001] The invention relates to the correct diagnosis and evaluation of soil environmental quality, in particular to a method and an experimental device for rapid diagnosis of soil health quality. Background technique

[0002] The correct diagnosis and evaluation of the environmental quality of agricultural soil is an important management basis for maintaining the virtuous cycle of the soil ecosystem and maintaining soil productivity, and it is also the premise of the production of pollution-free agricultural products. Due to the complexity and variability of soil properties and pollutant types, the diagnosis and evaluation of soil environmental health quality must take into account the abnormal changes of soil microorganisms, soil animals and plants. However, the toxicological diagnosis of conventional methods (such as half-lethal rate diagnosis method) often requires high pollutant concentrations and long experiment time, and common farmland soil contaminat...
