一、研究目的水稻是我国粮食生产中占比重最大、总产量最多的粮食作物。水稻土几乎遍布全国,南起崖县、北至漠河、西达西藏、东到台湾,都有水稻土分布,因此,如何解决农业机械下水田的问题,特别是下深泥脚水田的问题,是加速实现水田机械化和夺取水稻高产的关 First, the purpose of research Rice is China’s grain production accounted for the largest proportion of the total output of food crops. Therefore, how to solve the problem of paddy field under agricultural machinery, especially the problem of paddy field under deep muddy paddy soil is that paddy soil is distributed almost all over the country, from South Cliff County, north to Mohe, west Tibet, east to Taiwan Speeding up the mechanization of paddy fields and seizing the high yield of rice
