摘　　要：[目的]研究以凹凸棒土为原料的不同土壤处理方法对人参种植土壤的改良效果,探究人参种植前土壤改良方法。[方法]以种植人参土壤为研究对象,以田园土为对照,对6种处理下土壤肥力、土壤酶活性、土壤重金属含量进行测定分析。[结果]各处理对土壤的全磷、全钾和速效氮含量无显著影响,除了处理6土壤中酸性速效磷含量降低,其余处理都得到提升,其中处理3提升最多。处理1、3、4、5可显著或极显著提升土壤过氧化氢酶活性。土壤纤维素酶活性在2、4、5、6处理下得到了显著或极显著提升,而处理1、3极显著降低活性。除了处理4和5外,土壤中多酚氧化酶活性均得到了极显著提升。各种处理均极显著降低了土壤中脲酶的活性。所有处理土壤中铜、铅、砷含量均极显著低于农用地土壤污染风险筛选值;所有处理均可以极显著降低镉含量;处理2可以有效降低土壤中汞含量,处理后土壤无汞污染风险。[结论]该研究为下一步开展凹凸棒土改良人参种植土壤对人参生产的影响提供数据支撑。[Objective]The aim was to study the improvement effect of different soil treatment methods using attapulgite as raw material on ginseng planting soil,and explore the soil improvement method before Panax ginseng planting.[Method]The soil fertility,soil enzyme activity and soil heavy metal content under 6 kinds of treatment were measured and analyzed with ginseng planting soil as the research object and pastoral soil as the control.[Result]All treatments had no significant effect on the contents of total phosphorus,total potassium and available nitrogen in soil.Except for treatment 6,the content of acid available phosphorus in other treatments was reduced,and treatment 4 increased the most.Treatments 1,3,4 and 5 significantly increased soil catalase activity,soil cellulose activity was significantly increased under treatments 2,4,5 and 6,and significantly decreased soil cellulase activity under treatments 1 and 3.Except for treatment 4 and 6,the activity of polyphenol oxidase in soil was significantly increased,and the activity of urease in soil was significantly decreased by all treatments.The contents of copper,lead and arsenic in all treated soils were significantly lower than the screening value of soil pollution risk of agricultural land.All treatments could significantly reduce the content of cadmium,and treatment 2 could effectively reduce the content of mercury in soil,and there was no risk of mercury pollution in soil after treatment.[Conclusion]This study provided data support for the next step to carry out the influence of attapulgite modified ginseng planting soil on P.ginseng production.
