摘    要:通过室内培养试验,研究了石灰、沸石、石灰+沸石对菜园酸化土壤的改良效果。结果表明:单施石灰、石灰和沸石混用都能提高土壤pH值,显著或极显著降低土壤中交换性铝含量,减少铝毒,而单施沸石对土壤交换性铝无明显影响。施用不同改良剂的各处理的阳离子交换量都高于对照,范围在0.17-5.71cmol·kg^-1之间;土壤交换性盐基总量和盐基饱和度也有所增加,且与对照存在显著或极显著差异。与对照相比,施用不同改良剂能小幅增加土壤有机质含量,显著增加土壤速效钾含量(增幅15.0—135.0mg·kg^-1),而有效磷和碱解氮含量则有所降低。

关 键 词:酸化土壤  改良剂  石灰  沸石

Abstract:The indoor culture experiment was conducted to study the improved effects of lime,zeolite,lime + zeolite on acidizing vegetable soil. The results showed that applying lime or lime + zeolite could enhance pH of soil,and significantly or extremely significantly reduce the exchangeable aluminum content in soil and aluminum poison,while it had no obvious effect on exchangeable aluminum in soil by applying zeolite. Compared with the control,the cation exchange capacity was higher in different modifier treatments...
Keywords:acidizing soil  modifier  lime  zeolite
