摘　　要：本试验选用磷矿粉、沸石、膨润土等非金属矿物材料,利用机械力化学方法加工制成土壤改良剂,继而采用盆栽试验法,研究矿物改良剂及配施有机肥对盐渍土壤的改良效果及对玉米生长的影响。结果表明,施用矿物改良剂均可降低盐渍土壤的可溶性盐含量,其中微晶化磷矿粉+活化沸石粉配施有机肥处理(PR3)效果最佳,可溶性盐含量显著低于其他处理;微晶化磷矿粉与沸石粉或膨润土混合处理pH值均降低,但差异不显著,但PR3处理较空白对照降低4.49%,差异达显著水平。施用不同改良剂均可促进玉米植株生长,提高其鲜重和干重,其中活化的沸石粉和膨润土粉处理效果优于未活化处理,且以添加有机肥处理的PR3效果最佳。In this experiment,phosphate powder,zeolite,bentonite and other non-metallic mineral materials were used to make soil ameliorant by mechanochemical method.The pot experiment was used to study the effects of mineral ameliorants combined with organic fertilizer on improvement of saline soil and growth of corn.The results showed that the application of the mineral ameliorants could reduce the soluble salt content of saline soil,and the effect of microcrystalline phosphate powder+activated zeolite powder combined with organic fertilizer(PR3)was the best with significantly lower soluble salt content compared with the other treatments.The pH value decreased under the treatments of microcrystalline phosphate powder mixed with zeolite powder or bentonite,but the difference was not significant.However,the pH value of the PR3 treatment decreased by 4.49%compared with the blank control,and the difference was significant.The application of different ameliorants could promote the growth of corn plants and increase the fresh and dry weights of plants.The effects of activated zeolite powder and bentonite powder treatments were better compared to ordinary treatments,and the effect of PR3 treatment was the best.
