对2BYF-6型油菜免耕直播联合播种机在洞庭湖区的安乡县、沅江市、鼎城区、澧县等进行了田间播种试验.试验结果表明,采用2BYF-6型油菜免耕直播联合播种机的适宜土壤含水率为20%～40%,能够保证单位面积的基本苗数.与人工直播相比,节省成本32.0%,同育苗移栽相比,节省成本60.3%.试验结果显示采用2BYF-6型油菜免耕直播联合播种机在洞庭湖区的机播油菜试验是成功的.机具性能可靠,具有较高的经济价值和社会效益,通过生产实践,总结了机械技术与农艺科学结合的经验,为大面积推广油菜机械化播种提供了可靠的依据.

There is substantial need of automated seeders to improve the efficiency and accuracy in seeding. This paper reports the application of 2BYF-6 type no-tillage rape combine seeder in Yuanjiang, Dingcheng, Lixian and Anxiang counties in Hunan Province. The experimental results show that the no-tillage rape combine seeder is appropriate when soil moisture content is between 20% and 40%. Although, the machine can meet the requirement of seedling density per unit area with reducing the cost by about 32%, in comparison with that of working by hand. The cost incurred with planting seedling decreases ...
