2BD-7型多功能精密耕播机的研制与试验研究

Manufacture and Study on Precision Furrowing and Seeding Machine 2BD-7 Type

2BD-7 型多功能精密耕播机是与大豆“暗垄密”高产栽培技术相配套的播种机械,该机施肥采用滑刀式开沟器,可实现种、底肥的分层施撒;播种采用双条精量点播,可一次完成开沟、施肥、播种、覆土工序。生产试验表明,各行排量一致性、总排量稳定性均达到国标对播种大豆的播种质量指标。各项技术性能满足大豆“暗垄密”高产栽培技术所提出的农艺要求。

Soy precision furrowing and seeding machine 2BD-7 type is suitable for high yield cultivation technology of soy hidden ridge close planting, which have seeding and fertilizing functions and layered fertilization by ski-shaped disk. Double-row precision seeding was adopted. Drilling, fertilizing, seeding, and covering with soil could be completed in meantime. It was indicated by experimental result that its technological performance was met the need of high yield cultivation technology of soy hidden ridge close planting. Consistency and stabilization of total and row sowing quantity could achieve national criteria.
