摘　　要：利用优质低温敏核不育系‘金山s-2’与‘早恢89’配制的两系优质杂交早稻‘金两优289’,具有米质优、综合性状好等优良特性,推广前景好。为了探讨该品种最佳栽培技术,采用裂区设计研究了施纯N总量、插植规格对其产量的影响。结果表明:施纯N总量和插植规格处理对‘金两优289’产量影响都达到极显著水平,每666.7m2施纯N总量13.5kg,插植规格20cm×20cm产量最高。‘ JinLiangYou289 ＇,a high quality early two-line hybrid rice,which posses many excellent properties,such as high grain quality and comprehensively outstanding properties,and has a bright prospect in practical use,is bred by crossing ‘ Jinshan s-2 ＇ with restorer line‘ Zaohui89 ＇ . In order to investigate the best culture condition for ‘ JinLiangYou289 ＇,split plot design was used to study the effect of nitrogen usage and planting density on the yield of ＇ Jinliangyou289 ＇ . The results shows that both pure nitrogen contents and planting densities have significant effect on the yield of ‘ Jinliangyou289 ＇,and its peak yield is at the level of pure nitrogen content of 13.5 kg per 666.7 m 2 and planting specification 20 cm×20 cm.
