| 摘 要： | 为了研究黄绿木霉(Trichoderma aureoviride)T1010对土壤微生物群落、物理性状、化学性状的作用，评价T1010调整土壤环境性状生态效应的潜力。本研究采用土壤稀释法测定土壤中微生物群落数，土壤称重法测定物理性状，无机化学反应法测定土壤中主要化学指标含量。结果表明T1010促进土壤中细菌、放线菌、固氮菌的生长，与土壤处理前相比，固氮菌数量最大提高6.04倍，比对照提高58.02%，T1010抑制其他真菌的生长，比初始值下降52.99%，比对照下降79.47%；T1010改良物理性状，比重、容重比对照下降，总孔隙度趋近50%；水解氮、有机质比对照提高，与T1010的增殖正相关，有效磷比对照降低，与T1010负相关；T1010处理组侧根数比常规化肥处理组增加144%，立枯病感病指数降低36.36%。T1010具有改良土壤物理性状、提高微生物群体量、促进化学物质的可溶性等多种功能，是一种潜在、有效的土壤改良菌株。

| Abstract: | Modified potential of soil environment of Trichoderma aureoviride T1010 was assessed in soil by its adjustment on microflora population and physical and chemical properties.The population of microflora was isolated from soil by the dilution method of counting.The physical property was assessed by soil weighting in laboratory.The chemical property was assessed by chemical reaction.With cherry-tomato growing,the T1010 promoted the growth of some beneficial microflora.The azotobacter population was 6.04 times higher than that in the beginning,and 58.02% higher than the control.The T1010 controlled the growth of the other fungus.The population of the other fungus was 52.99% lower than that at the beginning,and 79.47% lower than the control.The T1010 adjusted the physical property,the soil specific gravity and bulk density became lower than the control,and the porosity was close to 50%.The N and organic matter were higher than those of the control.The available P was lower than that of the control.The T1010 population was negatively correlated with available P.The lateral root was 1.44 times higher than that in the control.The Rhizoctonia solani disease index was decreased by 36.36%.The T1010 is considered to be a potential soil-adjusting agent for amending the soil physical property,increasing some microflora,and promoting the solubility of chemical substances. |
