中文摘要	试验研究不同施肥方式下长期定位施肥对灰漠土农田土壤酶活性和土壤理化特性的影响结果表明:经过长期定位施肥试验,灰漠土土壤的生物活性(蛋白酶、脲酶、磷酸酶、蔗糖酶活性)与土壤基本肥力水平比试验前有所提高;不同施肥处理下土壤酶活性与土壤理化性质存在明显差异,N素和有机质含量是制约灰漠土土壤酶活性和影响作物产量的关键因子.
英文摘要	The grey desert soil was selected as the objective to study the dynamical changes of soil enzyme, soil chemical and physical properties through comparing the soil changes under different fertilizers in a long-term located experiment. The result shows that the main nutrient contents and soil enzyme activities are increased with the fertilizer added. Soil enzyme, soil chemical and physical properties are evidently different among different fertilizer treatments. Nitrogen and soil organic matter are the key control factors of soil enzyme and the yield of wheat in grey desert soil. Soil organic, soil total nitrogen and available nitrogen have obvious effects on soil proteinase activity, phosphatase activity, urease activity, and in-vertase activity. There is a significant correlation among soil enzyme,soil chemical and physical properties.
