2BM-2／3型免耕播种机的研制

２ＢＭ-２／３型免耕播种机与小四轮拖拉机相配套，能够一次完成扒秸破茬松土、播种施肥、覆土镇压等作业，播种沟低于地面５ｃｍ左右，还能起到探墒播种的作用。也适应于硬茬地和翻耕地，对麦茬地按时间复播玉米、大豆、向日葵等作物也有重要意义。

The Development of 2BM-2/3 No-tillage Seeding Machine

In order to solve the seeding and fertilization problems of maize and sorghum at dry land of half-covering with the whole stalk, 2BM-2/3 no-tillage seeding machine has been developed. This machine pulled by baby tractor can only once complete all field works of pushing aside the stalks, breaking the stubbles, loossening the soil, sowing the seeds, applying the fertilizer, covering the soil and compacting the soil. seeding furrow being approximate 5cm deeper than surface ground, sowing with this machine can fully use the moisture of the deeper soil. The notillage seeding machine can also be used in the hard stubble land and tillage land, it has same great signific. ance for rach planting of maize 、soybean、 sunflower etc. in the wheat stubbte land.
