| 摘 要： | 试验表明，播期对不同类型粳稻品种产量构成因素影响表现为：首先是每穗结实数或结实率，其次是千粒重，再次是每穗颖花数，而穗数／667m^2受影响甚小。就江苏淮北地区而言，宜推广应用中熟中粳品种。

| Abstract: | Field expriments proved that the yield components of different variety-types of japonica rice were influenced by seeding time as follows:the first effect was grains/panicle or seed setting percentage, the second effect was 1 000-grain weight and the third effect was spikelets/panicle, but panicles/667 m+2 was almost not influenced by the seeding time. In Huaibei area, the medium-maturing medium japonica rice (MMJR) is the proper type to be disseminated. |
