摘　　要：Ⅱ优118是江苏省大华种业集团有限公司以Ⅱ-32A/华恢118配组育成的三系杂交籼稻新组合,2003年1月通过江苏农作物品种审定委员会审定,2011年进行母本机插制种试验,以母本人工移栽作对照,观察其生育特性、茎蘖动态、群体穗粒结构和抽穗开花特性。结果表明:母本机插与人工移栽的实际产量无太大差异,但能很好的节省成本,减轻劳动强度、提高工作效率。The new combination of three-line hybrid indica which named Liangyou 118 were bred from II-32A/Huahui 118 by Dabua Group Co., Ltd, It was examined and approved by Jiangsu Provincial Variety Examination and Approval Committee in 2003 and be tested in 2011. manual planting on parent was used as control to research growth habits, culm and tiller dynamics, population structure of grains and the habits of tasseling and flowering. The results indicated that there is little difference between mechanized transplanting and manual planting on parent on the yield, but the former can cost savings, reduce labor intensity and boost workers performance.
