摘　　要：为了评价转基因抗虫耐除草剂大豆JD321对土壤生态系统的影响,该实验研究了其对土壤主要理化性质的影响。在大豆苗期、花期、鼓粒期和成熟期,分析了转基因大豆JD321对根际土壤含水量和pH值的影响。与其对应的非转基因大豆相比,转基因大豆JD321的根际土壤含水量和pH值没有明显变化,除草剂处理转基因大豆也没有对土壤含水量和pH值产生明显影响,但土壤含水量和pH值在不同生育期间存在明显差异。研究结果为转基因大豆JD321的环境安全性提供了新的支撑。In order to evaluate the effect of transgenic insect resistant and herbicide tolerant soybean JD321 on soil ecosystem,the effects of transgenic soybean JD321 on the main physical and chemical properties of soil were studied.The effects of transgenic soybean JD321 on rhizosphere soil water content and pH value were analyzed at the seedling stage,flowering stage,seed filling stage and maturity stage.Compared with its non-transgenic soybean counterpart,the rhizosphere soil water content and pH value of transgenic soybean JD321 did not change significantly,and herbicide treatment of transgenic soybean did not have a significant effect on soil water content and pH value,but there were significant differences in soil water content and pH value in different growth periods.These results provide new support for the environmental safety of transgenic soybean JD321.
