| Abstract: | Three-room rhizobox method were used to collect soil samples from three different root zones of maize growth room(S1),rhizosphere(S2) and non-rhizosphere(S3) respectively.The changes of content of soil microbial biomass C and N at 40 d、50 d and 60 d after sowing transgenic Bt maize and its parental maize without transgenic were studied.The results showed that the difference of soil microbial biomass C in three different root zones between transgenic Bt maize and non transgenic maize was not significant at 40 days,but the difference of microbial biomass N wais significant.The difference of soil microbial biomass C and N of Bt maize and non transgenic maize were significant at 50 d.At 60 days,the soil microbial biomass C and N of Bt maize significantly decreased in S1 root zone,the soil microbial biomass C decreased and soil microbial biomass N increased in S2 root zone of Bt maize,both of soil microbial biomass C and N in S3 root zone of Bt maize were higher than non transgenic maize.The ratio of soil microbial biomass C/N was significant difference between transgenic Bt maize and the parental maize and it changed according to root zones and growth period. |
| Keywords: | transgenic Bt maize soil microbial biomass C and N rhizobox |
