除草剂异丙隆对麦田土壤微生物数量及酶活性的影响
DOI: 10.3724/SP.J.1145.2010.00688, PP. 688-691
Keywords: 除草剂,异丙隆,土壤微生物数量,土壤酶活性,环境生态效应
Abstract:
为评价异丙隆的环境生态效应，在大田条件下研究异丙隆施入麦田后对土壤微生物数量及酶活性的影响.试验地前茬水稻，异丙隆浓度设0（清水，ck）、1.88、3.75、7.50、15.00g/kg5个水平.结果表明：异丙隆对麦田土壤真菌表现出短暂的抑制作用，处理后d5左右开始有激活效应，至d60仍具激活效应；对细菌及放线菌表现为抑制作用，且持续时间较长，到d15左右才开始表现出激活作用.异丙隆处理后，低浓度（1.88g/kg、3.75g/kg）对过氧化氢酶活性表现为激活―抑制―激活作用，而高浓度（7.50g/kg、15.00g/kg）则表现为抑制―激活作用；各浓度异丙隆处理对土壤脲酶活性均表现为抑制―激活作用；蔗糖酶活性对异丙隆比较敏感，开始表现为激活效应，其后逐渐趋于平缓，d60左右表现为抑制效应.图2参18
