汞污染稻田土壤调理剂效果研究
Study on the Effect of Soil Conditioners in Mercury-contaminated Rice Fields
摘要
Abstract
A total of 10 kinds of commercialized soil conditioner products of common brands on the market and soil conditioner products com-pounded by universities and scientific research institutes were selected to carry out field tests in mercury-polluted paddy fields in Jiangning Dis-trict of Nanjing,to explore the effects of these 10 soil conditioners on soil pH,soil mercury,soil nutrients and Hg content in rice grains.The results showed that compared with the control,the use of soil conditioner could improve soil pH,reduce soil mercury content and rice grain Hg content to some extent.At the same time,the application of soil conditioner could also effectively improve the content of soil organic matter,available phosphorus and available potassium,and reduce the content of alkali-hydrolyzable nitrogen.The mercury enrichment coefficient of rice could be reduced by different soil conditioners,with a decrease of 19.0%-62.6%.Among them,organic sulfur improver had a higher re-duction in grain BCF,followed by clay mineral-based soil conditioner and calcium silicate soil conditioner.关键词
