| 摘 要： | 研究了不同播栽期对水稻产量和产量构成因素及生育期的影响。结果表明 ,随播栽期推迟 ,水稻产量有所降低。每穗成粒数减少是推迟播栽期引起水稻减产的主要原因 ,其次是千粒重的下降和成穗数的降低。针对目前的生产实际 ,提出了一些应对播栽期推迟的技术措施。 |
| 关 键 词： | 水稻 播期 产量 产量构成因素 生育期 |

| Abstract: | In this experiment,the effects of seeding time on the yield,yield components and growth duration in different rice varieties were studied.The results indicated that the grain yield declined with the delaying of rice seeding time,mainly caused by decrease of ripened grains per panicle.In addition,the reduce of 1000-grain weight and ripened panicles also contribute to the yield decrease.For the need that have to delay rice seeding time,some corresponding countermeasures were provided. |
| Keywords: | rice seeding time yield yield components growth duration. |
