摘　　要：针对水稻传统直播方式存在的成本高、易倒伏、产量低、草害严重等问题,选取三种机型、两种水稻品种,在湖南省汉寿县水稻高产示范区进行了机械化直播高产栽培技术对比试验。试验结果显示,机械化穴、条播可实现一季晚稻直播的高效作业,每667m^(2)可减少成本76.87元(其中雇工43.33元、种子16.54元、除草剂17元),增产84.8 kg,增收210.3元,总共节支增收达287.17元,可有效减少“煮芽”现象、省种节本、增产增收、控制草害,在我国南方湖区具有较高的推广与应用价值。In response to the problems of high cost,easy lodging,low yield,and serious grass damage in traditional rice direct seeding methods,three types of machines and two rice varieties were selected to conduct a comparative experiment on mechanized direct seeding high-yield cultivation techniques in the rice high-yield demonstration area of Hanshou County,Hunan Province.The experimental results show that mechanized hole and drill sowing can achieve efficient operation of one season of late rice live broadcasting,reducing costs by 76.87 yuan per 667 square meters(including 43.33 yuan for hired workers,16.54 yuan for seeds,and 17 yuan for herbicides),increasing production by 84.8 kg,increasing income by 210.3 yuan,and saving a total of 287.17 yuan in expenses and income.It can effectively reduce the phenomenon of"sprouting",save seeds and costs,increase production and revenue,and control grass damage.It has high promotion and application value in the southern lake areas of China.
