A randomized field experiment with three replicates was conducted in the subtropical region of China to investigate the effects of integrated rice-duck system (RD) on methane (CH4) emission, active soil organic carbon fractions and their relationships in 2007 and 2008, compared with conventional rice system (CK). Methane emissions were measured at 7–9 days(More)
Transgenic Bacillus thuringiensis (Bt) rice have been reported to acquire effective resistance against the target pests; however, the insertion and expression of alien Bt genes may have some unintended effects on the growth characteristics of rice. A screen-house experiment was conducted and repeated twice to investigate the growth characteristics and Bt(More)
With hybrid rice cultivar Liangyou Peijiu as test material, this paper studied its biological characteristics and water use efficiency under effects of four irrigation modes. Compared with continuous flooding irrigation, intermittent irrigation increased the leaf area index, photosynthetic rate and water use efficiency, and decreased the leaf transpiration(More)
When addressing water shortage in rice production, we need to consider the influence of water-saving irrigation methods on soil organic carbon stocks (SOC). A typical rice–rapeseed rotation was irrigated using 3 different strategies in rice growing season over a 3 year period: continuous flooding (CF), alternate wetting and drying irrigation (AWD), and(More)
