转基因棉花根际土壤性质Transgenic; Cotton; Rhizosphere; Soil Properties



With the application and promotion of genetically modified crops, the safe of Bt-transgenic crops on soil had become one of the hot spot. In present study, two parallel experiments were conducted to compare the impacts of transgenic cotton on the rhizosphere soil properties in northern China. Research results show that: the cotton rhizosphere pH value most rise; soil organic matter in a full carbon, total nitrogen, available nitrogen in addition to a sampling point upward, the rest were decreased; available P, K content shows ascendant trend. In addition, the soil pH value, total carbon, total nitrogen, available nitrogen in interspecific differences with the strain variation, and the available P, available K does not exist for this change.
