日本九州农业试验场最近开发了一种在耙地的同时,将种子播入土中的新型水稻直播机,该机可由拖拉机牵挂,作业幅度为280cm,每次播种9行。该机采用了锯齿圆盘式投入器。作业时,当种子(氧化处理过的材料制成的包衣种子)自种子斗中流出后,圆盘式投种器即将包衣种子通过种子输出管播入由耙盘耙出的播种沟内,泥土也随之自动将种子覆盖好了。播入的种子深浅不一地散布在土中,其分散度适宜,平均发芽深度为1cm。每播种100平方米约需花
Japan’s Kyushu Agricultural Experiment Station recently developed a new rice direct seeding machine that seeding seeds into the soil while harrowing the ground, which can be traced by a tractor with a working range of 280 cm and sowing nine rows at a time. The machine uses a serrated disc type input device. During operation, after the seeds (coated seeds made from the oxidized material) flow out of the seed hopper, the disc seed is about to be seeded through the seed outlet tube into the seeded trenches rake , The soil will automatically cover the seeds well. Invaded seeds scattered in the depths of the soil, its decentralization, the average germination depth of 1cm. Each sowing about 100 square meters need to spend
