The super rice varieties of 'Tiejing 7' and 'Shennong 265' were used to study the matter production,yield and N use efficiency under different nitrogen application levels.The results showed that nitrogen level decreased by 30%(147kg·hm-2)compared to local nitrogen application 210kg·hm-2 did not reduce the yield significantly.The output rate of dry matters of leaf,stem and sheath of 'Tiejing 7' and 'Shennong 265' and contribution rate to yield had dropped,but the dry matter accumulation of ear… Expand
Effects of nitrogen level on yield and quality of japonica soft super rice
Abstract Although studies on the balance between yield and quality of japonica soft super rice are limited, they are crucial for super rice cultivation. In order to investigate the effects ofExpand
