水稻是我国主要的高产粮食作物之一,种植面积占粮食作物种植面积的22%,产量却占粮食产量的44%以上。近年来,南方地区双季稻面积不断扩大,北方地区水稻种植面积也不断增加。但是,种植水稻占用劳力多,劳动强度大,特别是南方“三抢”季节农活集中,季节性很强,劳动力紧张,实现水田作业机械化,特别是解决水稻栽培中的“三弯腰”问题,
Rice is one of the main high-yielding grain crops in China. Its planting area accounts for 22% of the total area planted with food crops, while its output accounts for more than 44% of the total grain output. In recent years, the area of double-cropped rice in the southern region has been constantly expanding, and the area under rice cultivation in the northern region has also been constantly increasing. However, planting rice occupies more labor and labor intensity, especially in the “three grab” seasons in the south. With concentrated seasonal workforce, intense labor force, mechanization of paddy field operations, and especially the “three-stooped waist” problem in rice cultivation,
