摘  要：
【目的】揭示松辽平原玉米带黑土酶活性变化规律,为建立有效的施肥制度提供参考.【方法】以松辽平原玉米带长期连作玉米的黑土为供试土壤,在田间调查、采样的基础上,测定不同区域、不同剖面构型("波浪型"和"平面型")下各类别土壤酶的活性,并对酶活性与土壤养分质量浓度进行相关性分析.【结果和结论】土壤酶在土壤循环中起到了生物学催化剂的作用,酶活性与土壤养分具有较强相关性,可以作为表征土壤肥力的指示性指标,其中脲酶活性表征不同条件下土壤肥力水平的效果较好.

摘  要：
【Objective】To reveal the variation law of black soil enzyme of Songliao Plain and provide reference to establish an effective fertilization system. 【Method】Black soil under continuous maize cultivation was taken in the corn belt of Songliao Plain as materials. Enzyme activities in different areas and sections("plant type "and "wave type") were determined based on field surveys and sampling correlation analyses between enzyme activities and soil nutrient contents were obtained.【Result and conclusion】Soil enzyme acted as the biological catalyst in a soil cycle. The activities of different kinds of enzymes were significantly correlated with the soil nutrient,so enzyme activities could be used to indicate the soil fertility. Furthermore,urease could indicate the soil fertility well.
