Abstract: Through field trials at the saline-alkali land test base in the garden field of Yinchuan City, Ningxia, we used chemical fertilizers in combination with bio-organic fertilizers to study their effects on saline-alkali soil chemical properties, soil microbes and their activities, wolfberry growth and quality. The results show that the reduction of chemical fertilizers combined with biological organic fertilizer treatment has obvious effects on reducing soil pH, total salt, alkalinity and bulk density. The reduction of chemical fertilizers combined with biological organic fertilizer can significantly increase the number of soil bacteria, nitrate reductase and nitrite reduction Enzyme, urease and alkaline xylanase activities and reduce the number of soil fungi and actinomycetes. The reduction of chemical fertilizer combined with the application of biological organic fertilizer treatment can effectively promote the plant height and crown growth of wolfberry, and have a certain effect on increasing the yield and 100-grain weight of wolfberry fresh fruit. The use of bio-organic fertilizer combined with chemical fertilizer can improve the utilization rate of chemical fertilizer, at the same time, it can repair the saline-alkali environment of saline-alkali soil, improve soil quality, and promote the growth of wolfberry and the quality of wolfberry. <br>Keywords: biological organic fertilizer; chemical fertilizer; soil microorganism; wolfberry; saline land;

摘要：通过在宁夏银川市园林场盐碱地试验基地大田试验，采用化肥减量配施生物有机肥，研究其对盐碱地土壤化学性质、土壤微生物及其活性、枸杞生长和品质的影响。结果表明：化肥减量配施生物有机肥处理对降低土壤pH 、全盐、碱化度和容重效果明显，化肥减量配施生物有机肥能显著增加土壤细菌数量、硝酸还原酶、亚硝酸还原酶、脲酶和碱性木聚糖酶活性并降低土壤真菌和放线菌数量。化肥减量配施生物有机肥处理能够有效促进枸杞株高和冠幅生长，对增加枸杞鲜果产量和百粒重具有一定的效果。利用生物有机肥配施化肥在提高化肥利用率的同时，可以修复盐碱地土壤盐碱环境，改善土壤质量，并能促进枸杞生长，提升枸杞子品质。<br>关键词：生物有机肥；化肥；土壤微生物；枸杞；盐碱地；

Abstract: through the field experiment in the saline alkali soil experimental base of Yinchuan garden farm in Ningxia, the effects of chemical fertilizer reduction combined with bio organic fertilizer on soil chemical properties, soil microorganisms and their activities, growth and quality of Lycium barbarum were studied. The results showed that the reduction of chemical fertilizer combined with bio organic fertilizer had obvious effect on reducing soil pH, total salt, alkalinity and bulk density. The amount of soil bacteria, nitrate reductase, nitrite reductase, urease and alkaline xylanase activities were significantly increased, and the number of soil fungi and actinomycetes was decreased. Reduction of chemical fertilizer combined with bio organic fertilizer treatment can effectively promote the growth of plant height and crown width of Lycium barbarum, and has certain effect on increasing the fresh fruit yield and 100 grain weight of Lycium barbarum. Biological organic fertilizer combined with chemical fertilizer can improve the utilization rate of chemical fertilizer, repair the saline alkali soil environment, improve the soil quality, promote the growth of Lycium barbarum, and improve the quality of Lycium barbarum.<br>Keywords: bio organic fertilizer; chemical fertilizer; soil microorganism; Lycium barbarum; saline alkali land;<br>
