| 摘 要： | 对小麦-玉米轮作区长期定位施肥土壤酶活性及其肥力变化的研究结果表明,与未施肥(对照)相比,长期施肥处理土壤脲酶、碱性磷酸酶、转化酶和过氧化氢酶活性均明显提高,其中有机肥(秸秆、厩肥)配施化肥效果明显优于单施化肥;施肥后休闲处理未提高土壤酶活性,表明施肥(化肥、有机肥)后作物根系及其分泌物具有刺激土壤酶活性的作用,且土壤酶活性高低与作物产量(即土壤肥力)相关性显著.

| Abstract: | The studies on the enzyme activities and fertility change of soils by a long-te rm located utilization of different fertilizers in wheat-maize rotation district show that the activities of unease,alkaline phosphatase,invertase and hydrogen peroxidase soils can be increased by a long-term fertilization,and th e effect of inorganic fertilizer combined with organic manure is better than that of only inorganic fertilizer,and the activity of soil enzyme can not be increa se d in fallow field after fertilization,showing that fertilization(inorganic and o rganic fertilizer)and crop rhizctaxis both can increase the activity of soil enz yme,and the activity of soil enzyme are positively correlated with crop yield (s oil fertility). |
