新型土壤调理剂对镉砷复合污染土壤修复效果的研究
|
摘要
为研究"润邦牌"土壤调理剂在稻田同步降低镉、砷含量的应用效果,选取湖南典型的红泥田,在施用本土壤调理剂后,考察土壤理化性质、水稻植株及土壤中镉和砷含量的动态变化。田间试验结果表明:该土壤调理剂可显著减少土壤和稻米中的镉砷含量,提高水稻产量。施用该土壤调理剂1 500～2 100 kg/hm~2,土壤中有效镉含量降低23.7%～44.8%,有效砷下降24.3%～40.5%,土壤pH值提高0.9～1.1个单位,稻米镉含量减少35.6%～51.1%,稻米砷含量降低22.0%～40.6%,水稻增产2%～5%。
To investigate the applying effect of "Runbang" soil conditioner on simultaneously decreasing cadmium(Cd) and arsenic(As) in early-season paddy field, a typical red mud field in Hunan Province was selected for monitoring the dynamic changes of Cd and As contents in early-season rice plants and soils, also including the soil physical-chemical properties and rice yields. Results of the field experiments indicated that the soil conditioner reduced Cd and As contents in the soil and rice grain significantly, while the rice yield got rising. Applied with 1 500-2 100 kg/hm~2 of soil conditioner, available Cd and As contents in soil were reduced by 23.7%-44.8% and24.3%-40.5%, while the soil pH value increased by 0.9-1.1 units, Cd and As contents in rice grain reduced by 35.6%-51.1% and 22.0%-40.6%, and rice yields increased by 2%-5%, respectively.
