清流县适宜机收再生稻品种筛选试验

摘要

10 photosensitive hybrid rice combinations were introduced and planted as ratooning rice in Qingliu county. The results showed that Yiyou 673, Jiayou 99 Yongyou 2640 and Tianyouhuazhan had good agronomic characters compared with the controls. These combinations were suitable for cropping area in the plains of Qingliu county trials.%针对再生稻头季适宜机收品种稀少，制约其规模化、机械化发展的现状，清流县选用10个优良品种进行再生稻头季机收栽培大区简比试验，以期筛选出适宜作高留桩头季机收再生稻品种。试验表明，适宜作高留桩头季机收再生稻品种有宜优673、嘉优99、甬优2640、天优华占等。
