【摘要】 [目的]探求超级稻武粳15超高产栽培的新途径。[方法]以超级稻武粳15为材料,从不同群体起点结构改革的角度设计处理进行比较研究。[结果]各处理中每穴摆栽3钵的处理产量最高,群体发展合理,抽穗后群体光合势大,干物质积累量多。[结论]初步提出以摆栽9.45万穴/hm2(40.0cm×26.7cm),每穴摆3钵,每钵2苗,基本苗57.0万/hm2的全新群体起点结构的超高产栽培途径。更多还原

【Abstract】 [Objective]Cultural approach of super-high yielding was searched.[Method]The research was designed from the structure of population of stems and tillers at transplanting with Wujing15 as material.[Result]The yield of three foramens treat was highest,whose population was rational.The LAD and weight of dry matters from heading to maturity of three foramens treat was highest too.[Conclusion]The new cultural approach of super-high yielding was in new structure of population of stems and tillers at transplanting,which planted 9.45×104 cave/hm2(40.0 cm×26.7 cm),3 foramens in each cave,2 seedlings in each foramen,basic seedling 57.0×104/hm2.更多还原
