中文摘要	为探究施用玉米专业菌肥对绿洲区玉米根际土壤理化性质和土壤酶活性的调理作用,寻求减少化肥施用量的有效途径。在甘肃武威黄羊镇设7个处理,不施肥(A),全量化肥(B),菌肥(不施化肥, C);85%化肥(85%B),85%化肥+菌肥(85%B+C),70%化肥(70%B),70%化肥+菌肥(70%B+C)。成熟期测定土壤养分、3大微生物计数和微生物量碳氮;并在苗期、拔节期、开花期和成熟期分别测定玉米根际土壤蔗糖酶、脲酶、碱性磷酸酶、过氧化氢酶活性和土壤呼吸。研究表明:85%B+C处理能够显著提高土壤全氮、全磷、有效磷和有机质含量;过氧化氢酶、蔗糖酶和脲酶在玉米的开花期达到最大值,碱性磷酸酶在拔节期达到最大值;蔗糖酶、脲酶和碱性磷酸酶含量均表现出处理85%B+C显著高于其他处理,过氧化氢酶处理B(全量化肥)高于其他处理,且A处理均表现为最低;施肥处理对土壤细菌数量的影响最大,是未施肥处理的1.97~5.01倍,此外,土壤真菌数量均表现出处理A(不施肥)显著高于其他各个处理;微生物生物量碳氮以85%B+C处理最优且显著优于其余处理;减量化肥并配施菌肥可以增加土壤呼吸速率。减量化肥并配施菌肥能够有效的提高绿洲区玉米地土壤的养分含量和酶活力,是减少绿洲区玉米化肥施用量的有效途径。
英文摘要	In order to explore the changes in physical and chemical properties and enzyme activities of soil in rhizosphere of maize,it is an effective way to reduce the amount of the utilized chemical fertilizers.The current experiment was carried out in arid regions(HuangYang Town,Gansu Province,China)with 7fertilization treatments(no fertilization(A);full fertilization(B);bacterial fertilizer(no chemical fertilizer,C);85% chemical fertilizer(85% B);85%fertilizer+bacterial fertilizer(85% B+C);70%fertilizer(70% B);70%fertilizer+ bacterial fertilizer(70%B+C).Each treatment was performed in triplicate then we measured soil nutrients,microbial counts and microbial biomass carbon and nitrogen at maturity,and in the rhizosphere soil at the seedling, jointing,flowering and maturity stages,soil sucrase,urease,alkaline phosphatase,catalase activity and soil respiration. The present finding showed that 85%B+C(85%fertilizer+bacterial fertilizer)treatment could significantly increase soil total nitrogen,total phosphorus,available phosphorus and organic matter content;catalase, sucrase and urease reached the maximum at the flowering stage of maize;the alkaline phosphatase reached maximum at elongation stage;the contents of invertase,urease and alkaline phosphatase showed that treatment 85% B+C was significantly higher than other treatments,and catalase treatment B(Full amount of chemical fertilizer) was higher than other treatments,and A treatment showed the lowest.The fertilization treatment had the greatest impact on the number of bacteria in the soil,which was 1.97~5.01times of unfertilized treatment.In addition,the number of soil fungi showed that A treatment(no fertilization)was significantly higher than other treatments,and microbial biomass carbon and nitrogen of 85%B+C treatment was optimally and significantly better than the rest of the treatments;reducing fertilizer and compound fertilizer could increase soil respiration rate.In summary,the reduction of fertilizer and the application of bacterial fertilizer could effectively improve the soil nutrient content and enzyme activity of corn in arid regions.
