摘要:
将玉米、大豆、甜菜三种作物根茬分别加入土壤中, 在不同温、湿度条件和不同氮素水平下培养后, 研究其对不同土壤酶的影响。结果表明, 加入根茬后, 玉米和甜菜的根茬使过氧化氢酶活性相对较强, 大豆根茬使过氧化氢酶的活性降低, 最大降幅为36.5%;玉米和大豆的根茬使蔗糖酶活性提高幅度大(20%～ 60%), 甜菜根茬影响不明显。在温度为15℃, 湿度20%, 不含氮条件下, 将玉米根茬加入土壤可以同时提高过氧化氢酶和蔗糖酶活性。
Abstract:
This study dealt with the effects of maize, beet and soybean stubble remaining in field o n soil enzyme activities, underthe different temperature, moisture and nitrogen content .The results showed that maize or beet stubble remaining in fieldcould raise the activities of catalase , but which was decrease in soybean stubble remaining in field ;maize and soybean stubbleremaining in field could raise the activities of sucrase , which of beet stubble remaining in field was not obviously .Under15℃, 20% moisture and none nitrogen, maize stubble remaining in field could raise the catalase and sucrase simultaneously .
