摘　　要： 水稻是我国重要的粮食作物,稻米消费量与需求量大。为探索粮食高效生产途径,设计了2BD-10型水稻芽种精量成穴直播机。通过在湖南省的生产试验表明:该机为实现播栽功能体现的排种和开沟起垄特性,能保证精量播种和良好的水稻通风透光性能,有助于提高粮食产量和降低稻种的消耗。同时还表明,水稻直播破胸有助于保证本田基本苗数和产量。 Paddy rice is an important food - crop, and its consumption and requirement has the call in China. To develop high - efficient paddy production method, A new 2BD - 10 precision hill - sowing direct - drill of paady sprout is designed and studied. The experimental extending and production results in Hunan shows that tha machine could make the precise sowing and nice airiness and light -penetrating come true and help to increase high yield and decrease consumption of the paddy seed because of the character of the meter - device and ditching and ridging to complete sowing function. and the results also show that the mbryonic paddy - seed can help to develop enough basic - young - plants and high - yields.
