播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)按(an)(an)種(zhong)(zhong)(zhong)子播(bo)(bo)(bo)(bo)到種(zhong)(zhong)(zhong)床的(de)形狀可分(fen)為(wei)撒播(bo)(bo)(bo)(bo)機(ji)(ji)、條(tiao)播(bo)(bo)(bo)(bo)機(ji)(ji)、穴播(bo)(bo)(bo)(bo)機(ji)(ji)；按(an)(an)動力(li)可分(fen)為(wei)人力(li)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、畜力(li)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)和機(ji)(ji)械播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)；按(an)(an)排種(zhong)(zhong)(zhong)器(qi)取排種(zhong)(zhong)(zhong)原(yuan)理可分(fen)為(wei)氣動式(shi)和機(ji)(ji)械式(shi)；按(an)(an)聯(lian)合(he)作(zuo)業形式(shi)可分(fen)為(wei)旋耕(geng)(geng)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、覆膜(mo)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)、免耕(geng)(geng)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)(ji)。

播種機械工作原理

播(bo)種(zhong)(zhong)機通過傳動(dong)系統(tong)帶動(dong)排(pai)種(zhong)(zhong)器(qi)、排(pai)肥器(qi)，按(an)要(yao)求(qiu)種(zhong)(zhong)肥量將從(cong)種(zhong)(zhong)肥箱進入排(pai)種(zhong)(zhong)器(qi)和(he)排(pai)肥器(qi)的(de)(de)種(zhong)(zhong)子(zi)和(he)肥料排(pai)到由開(kai)溝(gou)(gou)器(qi)開(kai)好(hao)的(de)(de)種(zhong)(zhong)溝(gou)(gou)和(he)肥溝(gou)(gou)里，隨后覆土器(qi)覆土，鎮壓器(qi)壓實(shi)種(zhong)(zhong)床，完成(cheng)播(bo)種(zhong)(zhong)作業。

播種機械的構造和工作過程

播(bo)(bo)種(zhong)機一般由(you)種(zhong)子箱(xiang)、排種(zhong)器、輸種(zhong)管、開(kai)溝(gou)器、覆土(tu)器、行(xing)走輪、轉動機構等組成(cheng)。工作時，開(kai)溝(gou)器在地上(shang)開(kai)出種(zhong)溝(gou)，種(zhong)子箱(xiang)內的種(zhong)子由(you)排種(zhong)器排出，經輸種(zhong)管落入種(zhong)溝(gou)，再由(you)覆土(tu)器覆土(tu)完成(cheng)播(bo)(bo)種(zhong)作業。

如何選購播種機

選購播種機應根據作業的面積、田地的地勢、播種的深度、土壤的質地和干濕度等因素選擇合適的型號。選好型號后要確定播種機的質量，選購的播種機品牌應(ying)外觀整潔完好(hao)，有(you)可靠的防護(hu)裝置，記得索要發票。

播種機怎么用

播(bo)(bo)種(zhong)機在(zai)播(bo)(bo)種(zhong)時，應(ying)(ying)按(an)照種(zhong)子(zi)(zi)(zi)的特點，對其(qi)進行(xing)播(bo)(bo)種(zhong)。如播(bo)(bo)種(zhong)的行(xing)距(ju)應(ying)(ying)該(gai)控制在(zai)20厘米左(zuo)右，不(bu)能過(guo)(guo)寬也(ye)不(bu)能過(guo)(guo)窄。播(bo)(bo)種(zhong)深(shen)(shen)度(du)應(ying)(ying)控制在(zai)1.5—3.0厘米，但是也(ye)要考慮到特殊(shu)情(qing)況，不(bu)同的土(tu)壤(rang)播(bo)(bo)種(zhong)的深(shen)(shen)度(du)也(ye)不(bu)同，土(tu)壤(rang)偏旱(han)，播(bo)(bo)深(shen)(shen)就要略深(shen)(shen)一點，這樣可以防止種(zhong)子(zi)(zi)(zi)播(bo)(bo)淺(qian)，土(tu)壤(rang)過(guo)(guo)干而(er)不(bu)能生長。因此，農機手在(zai)播(bo)(bo)種(zhong)時，一定要充分考慮種(zhong)子(zi)(zi)(zi)、土(tu)壤(rang)等情(qing)況，確(que)保種(zhong)子(zi)(zi)(zi)的健康成長。
