摘　　要：为了明确牡蛎壳土壤调理剂对稻田土壤环境及水稻生长的影响,选择特贝钙牡蛎壳土壤调理剂,在轻度酸化土壤且重金属有效含量超标的稻田开展大田试验,研究不同调理剂用量(0、1500、3000、4500 kg·hm-2)对土壤pH、重金属有效性及水稻产量和经济效益的影响。结果表明,通过调理剂的施用能够明显缓解土壤酸化,pH值提高3.04%~7.02%;降低重金属有效性,有效铬、有效铅含量分别下降15.63%~31.25%、9.05%~14.03%;增加土壤钙素供给水平,交换性钙含量提高7.95%~45.87%。此外,调理剂还能够在一定程度上提高水稻的产量,但总体经济效益随着调理剂用量的提高呈下降趋势。In order to clarify the effects of the soil conditioner of oyster shell on the paddy soil environment and rice growth,the soil conditioner of oyster shell Tebeigai was selected to carry out the field experiments in the paddy fields with mildly acidified soil and excessive effective content of heavy metals,in order to study the effects of different amounts of conditioner(0,1500,3000,and 4500 kg·hm-2)on the soil pH,heavy metal bioavailability,rice yield and economic benefits.The results showed that,the application of conditioner could obviously relieve the soil acidification,and the pH value was increased by 3.04%-7.02%;reduce the bioavailability of heavy metal,and the contents of available chromium and available lead were decreased by 15.63%-31.25%and 9.05%-14.03%,respectively;increase the supply level of soil calcium,and the content of exchangeable calcium was increased by 7.95%-45.87%.In addition,the conditioner could also improve the yield of rice to a certain extent,but the overall economic benefits decreased with the increase of the amount of conditioner.
