凹凸棒复合土壤调理剂对苦荞产量及重金属吸收量的影响

Effect of Attapulgite Compound Soil Conditioner on Tartary Buckwheat Yield and Heavy Metal Absorption

研究了凹凸棒石、土壤修复调理剂LC-L01对苦荞产量及根、茎和籽粒中重金属吸收量的影响。结果表明,施凹凸棒石粉(3000 kg/hm^2)+土壤修复调理剂LC-L01(1500 kg/hm^2)苦荞产量较不施添加剂提高36.65%,苦荞籽粒中Zn、Cd、Pb的吸收量分别较不施添加剂降低20.78%、57.89%、48.66%,具有修复土壤重金属污染的积极效应。

The effects of attapulgite and soil remediation regulator LC-L01 on the yield of Tartary buckwheat and heavy metal uptake in roots,stems and grains of tested crops were studied.The results showed that the yield of tartary buckwheat increased by 36.65%when applied attapulgite powder(3000 kg/hm^2)+soil remediation regulator LC-L01(1500 kg/hm^2),and the absorption of Zn,Cd and Pb in tartary buckwheat seeds decreased by 20.78%,57.89%and 48.66%,respectively,compared with that without additives,which had a positive effects on remediation of soil heavy metal pollution.
