采取2种灌溉方式(长期淹灌和节水灌溉)和4种施氮水平(纯氮0、135、180和225 kg/hm~2),研究了不同水肥耦合处理对双季杂交晚稻丰源优227物质生产的影响。结果表明,氮素能促进水稻生物量的增加,节水灌溉方式有利于生物量的积累,以节水灌溉下中氮处理(施氮量180 kg/hm~2)的生物量最高。叶面积指数对水稻产量的形成有极显著促进作用;叶面积指数随着施氮量增加呈先升后降的趋势,且节水灌溉处理有利于叶面积指数的提高。水稻产量与水稻的净同化率无明显相关性,与光合势呈极显著正相关,而光合势随施氮量的增加呈上升趋势。物质转运受施氮量影响,茎叶表观输出量、茎叶表观输出率、茎鞘物质转化率、茎鞘物...

The effects of different water and fertilizer coupling treatments on the plant production of Fengyuanyou 227, a double-cropping hybrid rice variety, were analyzed by using two irrigation methods（whole-course flood irrigation and water-saving irrigation） and four nitrogen application rates（pure nitrogen at 0, 135, 180 and 225 kg/hm-2）. The results showed that the application of nitrogen increased the biomass of rice. The water-saving irrigation was beneficial to the increase of biomass and the biomass was highest under the treatment with the...
