| 摘 要： | 对长期不同培肥制度下黑土磷酸酶活性进行研究。结果表明,中性磷酸单酯酶活性最高,磷酸二酯酶活性次之,磷酸三酯酶活性最低。不同施肥处理中性磷酸单酯酶活性顺序为:NPKNKM1+N2PK秸秆+N3PKCKM2+N1PK。磷酸二酯酶活性顺序为:M1+N2PKM2+N1PK秸秆+N3PKCKNKNPK。磷酸三酯酶活性各处理间无显著差异。

| Abstract: | Organic phosphorus turnover is regulated by phosphatase.As most of the organic P inputs to soil are phosphate diesters and monoesters,it therefore seems likely that phosphomonoesterase and phosphodiesterase activities regulate organic P turnover in black soils.A long-term experiment was set up in Gongzhuling Long-term Fertilization Station of Jilin Province to investigate application of six fertilization treatments on soil phosphase enzyme activities.Treatments included Control,NP,NPK,NPK+M1(Farm yard manur... |
