| 摘 要： | 针对黄土高原丘陵水蚀区残茬覆盖免耕播种及抗旱播种的作业要求，研制了以8.8～11.0?kW手持拖拉机为动力源的2BFM-5型山地免耕播种机。该播种机采用长翼尖角组合式种肥分施开沟器、复合铰链前位双轮仿形机构和螺旋齿槽轮排种器。田间试验表明：该播种机排种均匀性变异系数为35.4%，播深合格率为81.8%，平均种肥间距为44.0?mm，化肥集中在90～100?mm土层范围内，地表可形成宽66～85?mm、深40～52?mm的小垄沟，各项技术性能满足农业种植要求。该播种机适应中国黄土高原丘陵水蚀区缓坡地（＜15°）和水平梯田的免耕播种，满足雨养农业区播种技术的“深种浅覆、镇压提墒、集雨抗旱”等要求。

| Abstract: | According to the operational requirements for stubble mulch no-till sowing and drought-resistance sowing in the water erosion area of Loess Plateau,2BFM-5 hilly no-till seeder has been developed,whose power source was a hand tractor with 8.8-11.0kW power.The seeder adopted the long-wing and cusp combined opener in which the seed and the fertilizer were discharged separately,and the double-wheel profiling mechanism with ante-position compound hinges and the helical tooth fluted wheel.The field experiment sho... |
