摘要
以３０８８Ｓ×Ｒ１５１４和汕优６４进行的对比研究结果表明：３０８８Ｓ×Ｒ１５１４较之汕优６４光合速率大，后期叶面积系数高，且干物质积累快；产量高与其穗大、粒重和结实率高有关；分蘖力较弱，有效穗较少。讨论了高产栽培技术对策．
The photosynthetic characteristics and yield components of 3088 S/R1514 andShanyou 64 of hybrid rice were studied.The results showed that 3088 S/R1514 has biggerphotosynthetic rates in the whole period of duration, higher leaf area index(LAI)and fasterdry matter accumulation in the late growth stage than Shantou 64 has.High grain yield of3088 S/R1514 is ralated to the characteristics of large panicle and great grain-weight as wellas high grain fertility;but number of panicles of 3088 S/R1514 is less than that of Shanyou64.
