摘　　要：为了解决目前金衢地区双季稻生产存在的早晚稻生育期衔接矛盾、早晚稻适宜高产主栽品种不突出以及双季稻周年高产高效种植问题,通过开展双季稻周年高产高效研究,探讨适宜金衢地区的双季稻周年高产品种结构和种植方式。结果表明,早稻‘中嘉早17’直播搭配晚稻‘甬优15’手插模式的周年产量最高,达到18175.5kg/hm2,周年效益达19519.5元/hm2;早稻采用‘中嘉早17’直播搭配‘甬优15’机插模式的周年产量为28584.0kg/hm2,周年效益为14854.5元/hm2;早稻采用‘株两优609’直播搭配晚稻‘钱优0506’机插模式的周年产量为15549.0kg/hm2,周年效益为16867.5元/hm2。金衢地区种粮大户早稻采用直播方式选择生育期相对较短的‘株两优609’或‘金早09’等,搭配机插晚稻‘甬优15’或‘钱优0506’;大户选用双季机插模式,早稻可选择‘中嘉早17’等中、迟熟品种,搭配‘甬优15’或‘钱优0506’等品种,即可获得较高的收益,又可合理安排播插和收获时间。For the double cropping rice issues of growing period of convergence, less suitable for high-yielding varieties and high-yield cultivation, varieties and cultivation patterns were studied to investigate appropriate varieties and cultivation patterns for Jinhua and Quzhou area. The results showed that, the anniversary yield and effectiveness of ＇Zhongjiazao 17＇ with direct seeding for early rice, and ＇Yongyou 15＇ with hand planted for late rice was 18175.5 kg/hm2 and 19519.5 yuan/hm1, respectively. The anniversary yield and effectiveness of ＇ Zhongjiazao 17＇ with direct seeding for early rice, and ＇ Yongyou 15＇ with machine-transplanted for late rice was 28584.0 kg/hm2 and 14854.5 yuan/hm2, respectively. The anniversary yield and effectiveness of ＇Zhuliangyou 609＇ with direct seeding for early rice, and ＇Qianyou 0506＇ with machine-transplanted for late late rice. The collocation model of midseason variety or late mature variety （＇Zhongjiazao 17＇） and variety （＇Yongyou 15＇ or ＇ Qianyou 0506＇） with machine-transplanted could get higher returns. Besides, it could get reasonable arrangements for sowing and harvesting.
