    摘要:

    設計了2BMQ-180/3型秸稈粉碎覆蓋玉米免耕施肥播種機, 提出了在破茬開溝器前安裝驅(qū)動立軸旋轉(zhuǎn)式秸稈粉碎裝置,，將秸稈和雜草粉碎并拋撒在地表的防堵措施,，并進行了田間播種性能試驗。試驗結果表明, 該機通過性良好,；種,、肥覆土深度變異系數(shù)分別為23.7%、20.8%,，粉碎秸稈長度小于10 cm的達到90%以上,，出苗率超過90%，提高了播種質(zhì)量,；實現(xiàn)了秸稈粉碎還田和免耕播種的聯(lián)合作業(yè)方式,，較好地滿足了我國北方一年兩熟區(qū)保護性耕作技術發(fā)展的需求。

    Abstract:

    2BMQ-180/3 type no-tillage maize planter with stalk mulch smashing and fertilizing was developed. The anti-blockage measures when using the smashing straw endings machine-driven by vertical shaft rotary to smash the straw and weeds and throw them on the surface of the fields before the opener to plough the ditch was put forward. Then, the machine’s work performance was tested. The results showed that the planter performed very well. Its variation coefficients of sowing fertilizer cover depth were 23.7% and 20.8%. The smashed stalk length was less than 10 cm which was up to more than 90%. The germination rate was more than 90%. This improved the germinative rate of the seeds and achieved the joint practices model of smashing the straw and no-tillage sowing. The model also meets the requirements of conservation tillage technology in the area. 
