播種機有哪些種類

播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)按(an)(an)種(zhong)(zhong)子(zi)播(bo)到種(zhong)(zhong)床的形狀可分(fen)(fen)為(wei)(wei)撒播(bo)機(ji)(ji)(ji)(ji)、條(tiao)播(bo)機(ji)(ji)(ji)(ji)、穴(xue)播(bo)機(ji)(ji)(ji)(ji)；按(an)(an)動(dong)力可分(fen)(fen)為(wei)(wei)人力播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)、畜力播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)和機(ji)(ji)(ji)(ji)械(xie)播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)；按(an)(an)排(pai)種(zhong)(zhong)器取(qu)排(pai)種(zhong)(zhong)原理可分(fen)(fen)為(wei)(wei)氣動(dong)式和機(ji)(ji)(ji)(ji)械(xie)式；按(an)(an)聯(lian)合(he)作業形式可分(fen)(fen)為(wei)(wei)旋耕(geng)播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)、覆膜播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)、免耕(geng)播(bo)種(zhong)(zhong)機(ji)(ji)(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)(zhong)機通過傳動(dong)(dong)系統(tong)帶動(dong)(dong)排(pai)(pai)種(zhong)(zhong)(zhong)器(qi)、排(pai)(pai)肥器(qi)，按要求種(zhong)(zhong)(zhong)肥量將從種(zhong)(zhong)(zhong)肥箱(xiang)進入排(pai)(pai)種(zhong)(zhong)(zhong)器(qi)和(he)排(pai)(pai)肥器(qi)的種(zhong)(zhong)(zhong)子和(he)肥料排(pai)(pai)到由開溝器(qi)開好的種(zhong)(zhong)(zhong)溝和(he)肥溝里，隨后(hou)覆土(tu)器(qi)覆土(tu)，鎮壓器(qi)壓實種(zhong)(zhong)(zhong)床，完成播種(zhong)(zhong)(zhong)作業(ye)。

播種機械的構造和工作過程

播種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)機一(yi)般(ban)由種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)箱、排種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)器、輸(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)管、開(kai)溝器、覆土(tu)(tu)器、行走輪、轉(zhuan)動(dong)機構等組成(cheng)。工作時，開(kai)溝器在地(di)上開(kai)出種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)溝，種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)箱內的種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)由排種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)器排出，經輸(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)管落入種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)溝，再由覆土(tu)(tu)器覆土(tu)(tu)完成(cheng)播種(zhong)(zhong)(zhong)(zhong)(zhong)(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外(wai)觀整潔完(wan)好，有可(ke)靠(kao)的(de)防護裝置，記(ji)得索要發票(piao)。

播種機怎么用

播(bo)種機(ji)在播(bo)種時，應按(an)照種子的特(te)點，對其進行(xing)播(bo)種。如播(bo)種的行(xing)距應該控制在20厘米(mi)左右，不(bu)(bu)(bu)能過寬也(ye)不(bu)(bu)(bu)能過窄。播(bo)種深(shen)度應控制在1.5—3.0厘米(mi)，但是也(ye)要(yao)考慮到特(te)殊(shu)情況，不(bu)(bu)(bu)同的土(tu)壤播(bo)種的深(shen)度也(ye)不(bu)(bu)(bu)同，土(tu)壤偏旱，播(bo)深(shen)就要(yao)略深(shen)一(yi)點，這(zhe)樣可以防止種子播(bo)淺，土(tu)壤過干而不(bu)(bu)(bu)能生(sheng)長。因此(ci)，農(nong)機(ji)手在播(bo)種時，一(yi)定要(yao)充分(fen)考慮種子、土(tu)壤等(deng)情況，確保種子的健(jian)康(kang)成長。
