粳稻新品种栽培试验

摘要

通过小区对比试验和大区展示,观察了解粳稻新品种在湖北省当阳市的生长发育规律、产量性状及农艺性状.结果表明,粳稻作中稻栽培生育期为124～156d,其中中稻1号、淮稻5号、宁粳3号、热粳优35与当地中籼稻生育期相当,适宜于油菜茬口作早中熟中稻栽培;WDR129和华粳295可作中迟熟中稻栽培；甬优12生育期较长,不宜作油稻茬口.%Through plot comparative test and large area display,growth and development rule,yield traits and agronomic traits of several new japonica rice varieties in Dangyang were observed.The results showed that growth period of japonica rice as mid-season rice was 124 to 156 d,among which the growth period of Zhongdao No.1,Huaidao No.5,Ningjing No.3,Rejingyou 35 was equivalent to that of local indica rice and was suitable for culturing as early ripening mid-season rice with rape stubbles; WDR129 and Huajing 295 could be used as medium late ripening mid-season rice; Yongyou 12 had a long growth period,which unfavorable for rape-rice stubbles.
