凹凸棒石施用对镉污染土壤理化性质及小白菜生长的影响
Effects of Attapulgite Application on Cd Contaminated Soil' s Physical and Chemical Properties and Chinese Cabbage' s Growth
摘要
Abstract
[Objective]TheObjective was to pinpoint the harness effect of Cd in soil by attapulgite .[Method]Using Chinese cabbage as test material, pot experiment was carried out.Growth vigor of Chinese cabbage and nutrient and heavy metal Cd content in soil were analyzed. [Result] Moderate addition of attapulgite could enhance the output of Chinese cabbage effectively, as well as soil pH ,while overdose of at-tapulgite (≥2.0%(m/m))could lead to the decline of soil available nutrients.Application of attapulgite showed significant effect on remedi-ation of Cd contaminated soil, which could reduce the content of available Cd in soil and the absorption of Cd in Chinese cabbage .[ Conclu-sion]Recommended adding proportion of attapulgite was 1.0 %( m/m) in this article.关键词
