摘要
选择热粳优35(粳杂)、甬优1540(籼粳杂交)、扬两优6号(籼杂,对照品种)3种水稻,考察不同播种期对其秧苗素质、生育进程、产量的影响,比较粳稻和籼稻的差别,探索在京山县适宜种植的粳稻品种和最佳播种期。试验结果表明:在试验所设定的3个高产播种期(4月25日、5月5日、5月15日)内,籼粳杂交品种甬优1540的产量高于对照品种籼杂扬两优6号和粳杂品种热粳优35。以产量为考察指标,适宜在京山县种植的粳稻品种为甬优1540(籼粳杂交),其适宜播种期为4月25日至5月15日。
The Effect of different sowing date of three kinds of rice including rejingyou35（japonica hybrid rice）,yongyou1540（indica ＆amp;japonica hybrid rice） and yangliangyou6（indica hybrid rice） on the seedling quality,growth stage,yield was investigated in the paper in order to seek the best rice cultivar and sowing date in our county.The results showed that：under the condition of same sowing date（April 25 th,May 5th, May 15th）,the yield of yongyou1540 was larger than yangliangyou6,which was a contrast and rejingyou35. taking yield as the selection index,yongyou1540 was suitable to be planted in Jingshan county and its best sowing date was April 25th -May 15th.
