超级稻早造早熟组合株两优819配套栽培技术

Early-ripe super rice Zhuliangyou 819's cultivation technology in early rice

株两优819是湖南亚华种业科学院育成的两系杂交早稻早熟组合,2006年通过广西壮族自治区农作物品种审定委员会认定。根据该组合的特征特性,以主要生育阶段的叶龄、日期与对应目标产量450～515kg/667m2的茎蘖动态指标作为主要调控目标,探讨其配套栽培技术。

Zhuliangyou 819 is a early-ripe hybrid combination bred by Hunan Yahua institute of seed science,which was validated by Guangxi Crop Variety Approval Committee in 2006.Based in its features and characters,to take the indexes of leaf age and date of each growth stage,and the stem-tillering dynamic indexes corresponding to yields of 450～515kg/667m^2 as the main controlling objec-tives,so that a series of cultivation technology was studied.
