摘　　要：介绍了金华市双季稻稻作方式的现状以及目前规模种植大户双季稻不同稻作方式的产量、生产成本和效益,分析了早晚稻直播、早晚稻机插和晚稻手插等稻作方式的优点和缺点,指出未来规模种粮大户在稻作方式的选择上,早稻应以直播和机插为主,晚稻以机插为主,直播为辅。The current status of planting mode for early and late rice in the double-cropping rice system in Jinhua City was introduced. The grain yield, production costs and returns of different planting modes widely adopted by large-scaled growers in the double-cropping rice system were surveyed. The strength and weakness were compared among different planting modes including the direct seeding mode and the mechanized transplanting mode for both early and late rice and the handed transplanting mode for late rice. It is concluded that direct seeding and mecha- nized transplanting will be the major planting modes for early rice while mechanized transplanting will be the domi- nant planting mode, with direct seeding as a supplementary, the future. for late rice in Jinhua City for large-scaled growers in
