摘  要：
为筛选到适宜黔北地区直播的优质杂交稻品种,以生产上应用面积较大的宜香4245为对照,选用近年来审定的5个优质稻品种在遵义市余庆县进行试验,同时开展宜香4245品种传统人工栽插与直播的同田对比研究。结果表明,各试验品种生长情况、农艺性状正常,均可直播种植。从产量来看,C两优华占、宜香优2115、内香优6139较高,较对照宜香4245分别增产20.82%、17.84%和13.76%。宜香4245作直播较人工栽插每667 m2增产19.56 kg,减少人工投入3.5个,节本增收420元。C两优华占、宜香优2115、内香优6139和宜香4245适宜在黔北相似生态区作直播栽培。

摘  要：
In order to screen the high quality hybrid rice varieties suitable for direct seeding in northern Guizhou, a comparison test was conducted using five high quality rice varieties approved in recent years were selected as materials, taking Yixiang 4245 as the control, which was used in large area in production. At the same time, a comparative study on traditional artificial planting and direct seeding of Yixiang 4245 was carried out. The results showed that the tested varieties could be planted as direct seeding rice. Com-pared with the control, the yield of C liangyouhuazhan, Yixiangyou 2115 and Neixiangyou 6139 were increased by 20.82%, 17.84%and 13.76%, respectively. The yield of Yixiangyou 4245 with direct seeding was increased by 19.56 kg/667 m2 compared with artificial planting, reduced labor input 3.5 per 667 m2, and saved cost by 420 yuan/667 m2. In the production of similar ecological areas in northern Guizhou, it is suggested that C-liangyouhuazhan, Yixiangyou 2115, Neixiangyou 6139 and Yixiang 4245 could be used for direct seeding cultivation.
