Device and method for evaluating the vertical growth avoidance of plant roots from pollutants

Abstract

The invention relates to a device for evaluating the vertical growth avoidance of plant roots from pollutants. The device comprises a housing, separators, guide rails, a scanning device and an actuator. The housing includes a base and a sidewall disposed on the base; the base and the side wall form the housing into a cavity with an opening; the separators are disposed in the housing and in the number of two or more; the separators are provided with through holes; the through holes are internally provided with an agar layer; two or more of the separators are respectively disposed on the side wall along a direction from the base to the opening and separate the cavity into more than two closed sub cavities; the guide rails are disposed outside the housing along the circumferential direction of the side wall; the scanning device is slidably disposed on the guide rails; and the actuator drives the scanning device to slide along the guide rails. The invention also relates to a method for evaluating the vertical growth avoidance of plant roots from pollutants. The evaluation apparatus and method of the present invention also have the advantages of significant improvement on test reproducibility and sensitivity of the monitoring.

Description

technical field [0001] The invention relates to an evaluation technology of ecological pollution situation, in particular to a device and method for evaluating the avoidance of vertical growth of pollutants by plant roots. Background technique [0002] With the development of the economy, more and more pollutants are discharged into the environment, and the ultimate destination is the soil. Excessive pollution will reduce the quality of the soil and reduce its ecological function. Especially in my country, nearly 20% of the soil is currently polluted. Pollutants in the soil seriously threaten the normal growth of plants. Pollutants first accumulate from the root system and are transmitted to the entire plant. Numerous studies have shown that the root system is often the organ with the largest accumulation of pollutants, and it is also the organ that suffers the most. However, in the process of continuous evolution, plants have formed the characteristics of strong perception...
