铬砷在土壤和作物体内积累与迁移规律的研究

本文通过动态盆栽模拟性试验,研究了城市(太原市)污水溉灌,铬和砷在耕作层土壤、作物(水稻、菠菜)系统内的积累与迁移的规律,及其对植物的生长和产量的影响。这种模拟性试验,对于科学地合理地利用城市污水灌溉农田,监测土壤污染动态并予报其发展趋势,进而针对性地进行防治,提供了依据,具有现实的实用价值。

THE RULE OF ACCUMULATION AND MOVEMENT OF Cr AND As IN SOIL AND INSIDE OF PLANT

Through the simulated experiment of the dynamic potted plant, the citY sewage irrigation (Taiyuan), the rule of accumulation and movement of Cr and As in the farming layer of the soil and the internal system of the plants (rice and spinach), and its effects on the growth and output of the plant are studied in this paper. This experiment, an experiment of practical value,provides scientific basis for the proper utilization of the city sewage in irrigation, the prompt monitoring of soil contamination, prediction of its trends, and prevention of its possible damage.
