摘　　要：为了探索不同水稻种植方式在武汉市的节本增效成效,以优质常规中稻黄华占人工直播为对照,进行4种轻简化种植方式下产量和种植效益的比较试验。结果表明,机械精量穴播省工、省时、产量最高;其次是机械抛秧。但是,其在育秧及运秧环节增加了劳动力成本,且产量比无人机直播方式的产量仅高465.5 kg/hm^(2)。因此,从节本增效的结果来看,武汉市水稻轻简化栽培方式应尽量选用机械精量穴播或无人机直播方式。In order to explore the effects of cost saving and efficiency increasing of different rice planting methods in Wuhan,a com⁃parative experiment on yield and planting benefit under four light and simplified planting methods was carried out with manual direct seeding(MDS)of high-quality conventional medium indica rice variety Huanghuazhan as the control.The results showed that among four planting methods,mechanical precise-quantity hill-drop drilling(MPHD)saved labor,time and highest yield,followed the seedling mechanical broadcasting(MB).However,it increased the labor cost in seedling raising and transportation,and the output was only 465.5 kg/hm^(2) higher than that of unmanned aerial vehicle direct seeding(UAVDS).Therefore,from the results of cost saving and efficiency increasing,the light and simplified cultivation mode of rice planting in Wuhan should prefer to choose MPHD or UAVDS as far as possible in the future.
