摘　　要： 研究了膨润土作为土壤改良剂对土壤化学性质和作物生长的影响,结果表明:改良后的土壤酸度降低,交换性酸含量降低,阳离子交换量、盐基离子总量增加,作物产量、分蘖数、植株高度增加;各处理中以处理⑤的效果最佳,处理④次之。 Effect of Bentonite as a kind of amendment on soil chemical character and crop growth were studied. The result showed soil active acidity and exchangeable acidity were reduced; CEC, TEB （total exchangeable base ） and S % were increased;and the output, height and number of litter were increased too. And effect of treatment ⑤ was best among five treatments and treatment ④ took second place.
