摘　　要：以常规籼稻品种徽丰丝苗、农香丝苗、广香丝苗、粤丝占、美香占3号、美香油占4号为材料,2021年设置一季中稻播期,2022年设置一季中稻和一季晚稻播期,采用同田对比进行种植试验。结果表明,常规籼稻作一季中稻种植时,播齐历期较丰两优四号短,品种生育性状年度间表现较稳定,产量较丰两优四号低;作一季晚稻种植时,参试品种生育性状与黄华占相近,徽丰丝苗和农香丝苗较黄华占增产,其余品种减产。在抽穗期,农香丝苗对不良天气有较强的抵抗力,粤丝占和美香占3号抗不良天气的能力较弱,徽丰丝苗和广香丝苗对高温敏感,美香油占4号对不良天气中度敏感。With Huifengsimiao,Nongxiangsimiao,Guangxiangsimiao,Yuesizhan,Meixiangzhan 3,Meixiangyouzhan 4 as the research materials,we carried out planting test by field comparison with one middle rice sowing period in 2021 and one middle rice and one late rice sowing periods in 2022.Results showed that when conventional Indica rice was planted in one middle season,its sowing period was shorter than Fengliangyou 4.The growth characters of varieties were stable from year to year.And its yield was lower than Fengliangyou 4.When conventional Indica rice was planted in one late season,tested varieties had similar growth period with Huanghuazhan;yields of Huifengsimiao and Nongxiangsimiao enhanced compared with Nongxiangsimiao,but those of other varieties reduced.At heading stage,Nongxiangsimiao showed stronger resistance to adverse weather,while Yuesizhan and Meixiangzhan 3 had poorer resistance to adverse weather.Huifengsimiao and Guangxiangsimiao were sensitive to high temperature,and Meixiangyouzhan 4 was middle sensitive to adverse weather.
