在温室条件下,采用植物盆栽试验,研究4种土壤调理剂不同施用量对酸性红壤铝毒害的缓解效果。结果表明,4种土壤调理剂均显著降低土壤中交换性铝含量及毒害性铝含量,显著提高玉米株高、生物量；各处理土壤中交换性铝含量与玉米株高及生物量之间呈显著相关性。牡蛎壳、白云石、钾长石、麦饭石4种土壤调理剂0．2%的施用量土壤交换性铝分别比对照下降了63．8%、70．5%、53．0%、12．3%；0．4%的施用量土壤交换性铝分别比对照下降了90．5%、92．0%、80．5%、23．4%。土壤中交换性铝、毒害性铝的含量随着4种土壤调理剂的施用量增加而降低,土壤中毒害性铝含量由低到高依次为白云石、牡蛎壳、钾长石、麦饭石。

A pot experiment was conducted to investigate the effects of soil conditioner on alleviating aluminum toxicity in acid red soil. The result revealed that all the four soil conditioner could significantly reduce the exchangeable aluminum content and the toxic aluminum content in soil, increase maize height and biomass. Soil exchangeable aluminum content were significantly correlated with plant height and biomass in all treatments. When 0. 2% soil conditioner was added, the soil exchangeable alumi-num of oyster shell, dolomite, potassium feldspar, maifan stone decreased by 63. 8%, 70. 5%, 53. 0%, 12. 3% respectively;and when 0. 4% soil conditioner was added, the soil exchangeable aluminum decreased by 90. 5%, 92. 0%, 80. 5%, 23. 4%respectively. The exchangeable aluminum and toxic aluminum in soil decreased with the increase of the application of soil condi-tioner. The toxic aluminum content in soil was: dolomite<oyster shell<potassium feldspar<maifan stone.
