| 摘 要： | 通过盆栽对照试验的方法,研究复合菌剂C1、C2对土壤理化性质及微生物活性的影响,结果表明：与对照相比,施用复合菌剂C1、C2能够减少土壤真菌的数量,在施菌剂早期可以增加土壤细菌的数量,对土壤放线菌影响较小;提高土壤有机质、碱解氮、速效磷、速效钾等土壤养分的质量分数,降低土壤酸度;同时还能够显著地增强土壤脲酶、磷酸酶、纤维素酶及过氧化氢酶的活性。进一步对各处理的土壤因素进行主成分分析,结果显示PC1为土壤碱解氮、速效磷、速效钾,PC2为土壤矿化氮、脲酶、纤维素酶。综合评价土壤质量,复合菌剂C2在各处理中综合得分最大。

| Abstract: | A pot experiment was carried out to study the effect of combination bacteria C1 and C2 on physicochemical properties and microbial activity of the soil.The results showed that applied combination of bacteria C1 and C2 reduce the number of soil fungi,increase the number of soil bacteria at the beginning stage,while have only slight effect on the number of soil actinomycete.Addi-tionally,the combination bacteria could increase the content of organic matter,available nitrogen,mineralized nitrogen,available pho... |
