摘　　要：为酸化土壤治理和安全利用提供依据,通过设置7个不同处理,分别为配方肥T1(CK)、配方肥+土壤改良剂(石灰粉T2、农用氢氧化镁T3、特贝钙土壤调理剂T4)、有机肥+土壤改良剂(石灰粉T5、农用氢氧化镁T6、特贝钙土壤调理剂T7),比较不同改良剂组合对茄子产量和重金属含量、土壤农化性状的影响。结果表明:与单施配方肥(CK)相比,在酸性土壤上施用有机肥+土壤改良剂、配方肥+土壤改良剂组合可显著增加作物产量,降低茄子重金属含量,改善土壤农化性状。在增加茄子产量、降低茄子Cr含量效果方面,有机肥+土壤改良剂组合优于配方肥+土壤改良剂组合,在降低茄子Cd含量效果方面,配方肥+土壤改良剂组合效果更好。在改良土壤农化性状效果方面,两者规律不明显。In order to provide the basis for the management and safe utilization of the acidic soil,seven different treatments were set up,including the formula fertilizer T1(CK),formula fertilizer+soil amendment(lime powder T2,agricultural-use magnesium hydroxide T3,terbegai soil conditioner T4),organic fertilizer+soil amendment(lime powder T5,agricultural-use magnesium hydroxide T6,terbegai soil conditioner T7).Then,the effects of different soil amendment combinations on the yield of eggplant,heavy metal content and soil agrochemical characters were compared.The results showed that compared with the single application of formula fertilizer(CK),the application of the combinations,such as the organic fertilizer+soil amendment and formula fertilizer+soil amendment in the acidic soil could significantly increase the crop yield,reduce the heavy metal content of eggplant and improve the agrochemical characters of soil.In terms of increasing the eggplant yield and reducing the chromium content of eggplant,the combination of organic fertilizer+soil amendment had a better effect than the combination of formula fertilizer+soil amendment.In terms of reducing the Cd content of eggplant,the combination of formula fertilizer+soil amendment had a better effect.In terms of the effect of improving the soil agrochemical traits,the influences of the two were not obvious.
