中文摘要	在宁夏干旱区弃耕盐碱地施用苦豆子草渣、苦豆子籽渣和甘草渣3种中药废渣,对表层土壤理化性质、微生物数量和土壤酶活性的变化进行了研究,探讨3种中药废渣改良弃耕盐碱地的效应。结果表明:施用3种中药废渣后,土壤容重、pH值、全盐均低于CK(未施药渣),其中pH值、全盐含量显著降低;土壤水分含量均显著高于CK;土壤养分含量全面提高,其中土壤有机质、全磷、速效氮、速效磷、速效钾得到显著提高,不同处理间速效氮、速效磷、速效钾差异显著(p<0.05),其中苦豆子籽渣提供速效氮、速效钾的能力显著高于甘草渣和苦豆子草渣,而甘草渣提供速效磷的能力显著高于苦豆子草渣和籽渣;施用废渣后的表层土壤细菌、真菌和放线菌数量均显著高于CK;苦豆子草渣、苦豆子籽渣和甘草渣对土壤碱性磷酸酶的活性有显著性的促进作用,苦豆子籽渣对土壤过氧化氢酶的活性有显著性的促进作用;土壤有机质、速效氮、速效磷、速效钾与土壤微生物的数量和土壤酶相互促进作用明显,有密切的相关关系。
英文摘要	The effects of grass residue of sophora alopecuroides,seeds residue of sophora alopecuroides and licorice residue on soil physical-chemical properties,microbial quantities and enzyme activities in abandoned salkaline land in arid area of Ningxia Hui Autonomous Region were studied.The results showed that the soil bulk density,pH value and total salt content after applied with residue were lower than not applied with residue(CK),especially the total salt content and pH value decreased significantly.Soil organic matter,total phosphorus,available nitrogen,available phosphorus and available potassium increased significantly,and there existed significant difference in available nitrogen,available phosphorus and available potassium between different treatments,and also,the ability to provide available potassium and available nitrogen of seeds residue of sophora alopecuroides is significantly higher than that of grass residue of sophora alopecuroides and licorice residue,the ability to provide available phosphorus of licorice residue is significantly higher than that of grass residue of sophora alopecuroides and seed residue of sophora alopecuroides.After the application of waste residue,the number of soil bacteria,fungi and actinomycetes were significantly higher than that of CK.The activity of alkaline phosphatase increased significantly by application of seed residue of sophora alopecuroides and licorice residue,and the activity of soil catalase increased significantly by application of seeds residue of sophora alopecuroides.Soil organic matter,available nitrogen,available phosphorus and available potassium showed a significant correlation with microbial quantities and enzyme activities, which were promoted each other.
