摘　　要：研究转Chi+Glu双价基因棉对土壤酶活性的影响,揭示其对土壤生态系统的安全性。在大田试验条件下,检测种植转Chi+Glu双价基因棉、转Bt基因棉和非转基因常规棉在不同生育期的土壤蔗糖酶、脲酶、碱性磷酸单酯酶、脱氢酶和过氧化氢酶活性。结果表明,转Chi+Glu双价基因棉在棉花不同生育期对土壤蔗糖酶、土壤脱氢酶和土壤过氧化氢酶的活性有较强的促进作用,而对土壤脲酶和土壤碱性磷酸单酯酶的活性具有一定的抑制作用。结果显示,种植转Chi+Glu双价基因棉花不会影响棉田土壤生态系统的安全性。Through studying effects of transgenic Chi＋Glu cotton on soil enzyme activities,we aimed to reveal the safety of transgenic cottons on the soil ecology environment.In field experiments,the activities of invertase,urease,alkaline phosphatase,catalase,and dehydrogenase in soil in which grown transgenic Chi＋Glu,Bt cotton and un-transgenic conventional cotton were tested in different cotton growth periods.The result showed that transgenic Chi＋Glu cotton in different growth periods played a promoting effect on activities of invertase,catalase and dehydrogenase in soil,while,to some degree,it inhabited urease and alkaline phosphatase in soil.Therefore,transgenic Chi＋Glu cotton did not affect the safety of cotton soil ecosystem.
