| 为探讨母本机械化插秧对杂交稻制种产量的影响，以博优225 的父母本为材料，采用母本机械化
插秧和人工手插两种移栽方式，开展两年三地的制种试验，调查和比较了机械化插秧和人工手插方式下母本
群体的苗情动态以及产量构成差异，分析了影响杂交水稻制种产量的因素。结果表明：机械化插秧方式下母本
群体的基本苗数、最高苗数、冠层厚度、有效穗数、每穗实粒数、结实率、理论产量和实测产量均高于人工手
插群体；在所调查的苗情指标和产量构成因素中，与制种产量相关程度最大的分别是最高苗数和每穗实粒数；
母本机械化插秧有利于增加群体最高苗数和每穗实粒数，从而提高杂交水稻制种产量。 |
| 英文摘要: |
| To explore the effect of transplanting female parent of hybrid rice by machine on seed yield，experiments
on seed production of hybrid rice“ Boyou225” were conducted，in which its female parent was transplanted by machine
and by hand，at three locations and in two years. Differences in growth dynamics and yield components were investigated
between machine- and hand-transplanted female parent populations. Factors affecting the yield of hybrid seeds were
analyzed. The results showed that，the number of seedlings per hill，the maximum number of tillers per plant，canopy
thickness，the number of productive panicles per plant，the number of filled grain per panicle，seed-setting rate，the
estimated production and the actual production were all more in machine-transplanted population than those in handtransplanted
population. Filled grain number and the maximum number of tillers were most closely related to the yield of
hybrid seeds，respectively，among yield components and among seedling growth indices. Transplanting female parent by
machine in hybrid rice seed production，was contributed to an increase in the maximum number of tillers and filled grain
number for the parent population，thus improving the yield of hybrid seed. |
