| 摘 要： | 研究了不同播期对扬辐粳8号产量、产量构成因素及生育进程的影响，两年试验结果表明，扬辐粳8号的适宜播期为5月上旬末至5月下旬初；播种时间太早或太迟均会由于结实率低、穗粒数不足导致扬辐粳8号极显著减产。

| Abstract: | Effect of different sowing time on yield,yield components and development process of Rice Yangfujing 8 was studied.The two-year trial results show that the suitable sowing time of Rice Yangfujing 8 was between the end of early May to the beginning of end May,planting too early or too late would lead to the significant reduction of output of Rice Yangfujing 8,the low setting rate and the less grains per spike were the main reasons. |
