摘　　要：通过对一些短生育期品种几年的栽培研究,现已提出一系列提高其生物产量和收获指数的技术措施,其基本内容是:视时晚播,适当早栽,本田提早追肥,据本田苗情及时排水烤田,抓好施穗肥、喷“920”等延缓衰老并提高结实率和千粒重的技术措施的落实。We have drawn some conclusions about improving life yield and harvest index for short-life-period hybrid rice through several years' cultivation research. The following are the main techniques, moderately late seed drop, moderately early transplant, early apply fertilizer after transplant, keep the field dry while the number of the seedling is sufficient. At the same time we can improve seed set and 1000-grain weight by utilization of panicle fertilizer and '920', which also can prevent the hybrid rice from getting old.
