| 摘 要： | 研究不同的化感物质ＦＡ，４－ｔ－ＢＡ，ＢＨ的不同浓度及其混合物对土壤脲酶活性的影响。研究结果表明，３种化感物质对土壤脲酶活性均有一定的刺激作用，其中４－ｔ－ＢＡ刺激作用最强，但持续时间短；ＢＨ的刺激作用弱，但持续时间长，不同化感物质对脲酶活性的最大刺激点随时间的不同而不同，其中４－－ＢＡ的５００ｍｇ．ｋｇ＾－１和ＢＨ的２００ｍｇ．ｋｇ＾－１均在第７ｄ，而ＦＡ的５００ｍｇ．ｋｇ＾－１在第display stru

| Abstract: | Three allelochemicals such as ferulic acid(FA),benzoldehyde(BH)and 4-tert-bytylbanzoc acid (4-t-BA) at different concentrations of single and mixture have been investigated for their effects on uricase activity.The results showed some stimulating effects of allelochemicals studied on uricase activety.4-t-BA among those has more strong effects than others,but the effected time is shorter,and BH has a weak effect but a longer effected time.Allelopathic effects are dependant on the allelochemicals concentration and time of their influence.The strongest effects were 7th day and 4th day for 500mg·kg-1 of 4-t-BA,200mg·kg-1 of BH and 500mg·kg-1 of FA,respectively.The stimulation of mixture of allelochemicals is stronger than a single at same concentration. |
