播種機有哪些種類

播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)按(an)(an)種(zhong)子播(bo)(bo)到種(zhong)床的形(xing)狀可分為撒播(bo)(bo)機(ji)(ji)(ji)(ji)、條播(bo)(bo)機(ji)(ji)(ji)(ji)、穴播(bo)(bo)機(ji)(ji)(ji)(ji)；按(an)(an)動力(li)可分為人力(li)播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)、畜力(li)播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)和機(ji)(ji)(ji)(ji)械播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)；按(an)(an)排(pai)種(zhong)器取排(pai)種(zhong)原(yuan)理(li)可分為氣動式(shi)和機(ji)(ji)(ji)(ji)械式(shi)；按(an)(an)聯合作業(ye)形(xing)式(shi)可分為旋耕(geng)(geng)播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)、覆(fu)膜播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)、免耕(geng)(geng)播(bo)(bo)種(zhong)機(ji)(ji)(ji)(ji)。

播種機械工作原理

播種(zhong)(zhong)機(ji)通過傳動系統帶(dai)動排(pai)種(zhong)(zhong)器(qi)(qi)、排(pai)肥(fei)器(qi)(qi)，按要求種(zhong)(zhong)肥(fei)量將從種(zhong)(zhong)肥(fei)箱(xiang)進入排(pai)種(zhong)(zhong)器(qi)(qi)和排(pai)肥(fei)器(qi)(qi)的種(zhong)(zhong)子(zi)和肥(fei)料(liao)排(pai)到由開(kai)溝(gou)器(qi)(qi)開(kai)好的種(zhong)(zhong)溝(gou)和肥(fei)溝(gou)里，隨后覆(fu)土(tu)器(qi)(qi)覆(fu)土(tu)，鎮壓(ya)(ya)器(qi)(qi)壓(ya)(ya)實(shi)種(zhong)(zhong)床，完成(cheng)播種(zhong)(zhong)作業(ye)。

播種機械的構造和工作過程

播(bo)種(zhong)(zhong)(zhong)(zhong)機一(yi)般由(you)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)箱(xiang)、排種(zhong)(zhong)(zhong)(zhong)器(qi)(qi)(qi)(qi)、輸(shu)種(zhong)(zhong)(zhong)(zhong)管、開(kai)溝(gou)(gou)器(qi)(qi)(qi)(qi)、覆土(tu)器(qi)(qi)(qi)(qi)、行走輪、轉動機構等組(zu)成。工作時，開(kai)溝(gou)(gou)器(qi)(qi)(qi)(qi)在(zai)地上(shang)開(kai)出種(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)箱(xiang)內的種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)由(you)排種(zhong)(zhong)(zhong)(zhong)器(qi)(qi)(qi)(qi)排出，經輸(shu)種(zhong)(zhong)(zhong)(zhong)管落(luo)入種(zhong)(zhong)(zhong)(zhong)溝(gou)(gou)，再由(you)覆土(tu)器(qi)(qi)(qi)(qi)覆土(tu)完成播(bo)種(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觀(guan)整潔完好，有可靠的防護裝置，記得索(suo)要發(fa)票(piao)。

播種機怎么用

播(bo)(bo)(bo)(bo)種機(ji)在播(bo)(bo)(bo)(bo)種時(shi)，應(ying)按(an)照種子(zi)的(de)(de)特點(dian)(dian)，對其進行播(bo)(bo)(bo)(bo)種。如播(bo)(bo)(bo)(bo)種的(de)(de)行距應(ying)該(gai)控(kong)制(zhi)在20厘(li)米左右，不能過寬也(ye)不能過窄。播(bo)(bo)(bo)(bo)種深(shen)度應(ying)控(kong)制(zhi)在1.5—3.0厘(li)米，但是也(ye)要考慮(lv)到特殊情況，不同的(de)(de)土壤(rang)播(bo)(bo)(bo)(bo)種的(de)(de)深(shen)度也(ye)不同，土壤(rang)偏(pian)旱，播(bo)(bo)(bo)(bo)深(shen)就要略深(shen)一(yi)點(dian)(dian)，這樣可以防止種子(zi)播(bo)(bo)(bo)(bo)淺，土壤(rang)過干而不能生長。因此，農機(ji)手(shou)在播(bo)(bo)(bo)(bo)種時(shi)，一(yi)定要充(chong)分考慮(lv)種子(zi)、土壤(rang)等情況，確(que)保種子(zi)的(de)(de)健康成(cheng)長。
