黑龍江播種機使用時(shi)注意(yi)事(shi)項：

　　1.播種的要求

　　播種機在播種時，應(ying)按照種子(zi)的特點(dian)，對(dui)其進行(xing)播種。如播種的行(xing)距應(ying)該控制(zhi)(zhi)在20厘米(mi)左(zuo)右(you)，不(bu)能過(guo)寬也不(bu)能過(guo)窄(zhai)。播種深(shen)度應(ying)控制(zhi)(zhi)在1.5—3.0厘米(mi)，但是也要考慮到特殊(shu)情況(kuang)，不(bu)同的土(tu)壤播種的深(shen)度也不(bu)同，土(tu)壤偏旱，播深(shen)就要略深(shen)一點(dian)，這樣可以防止種子(zi)播淺，土(tu)壤過(guo)干(gan)而(er)不(bu)能生長。因(yin)此，農(nong)機手在播種時，一定(ding)要充分考慮種子(zi)、土(tu)壤等情況(kuang)，確(que)保種子(zi)的健康成長。

　　2.播(bo)種機(ji)故障的注意事項

　　由于操(cao)作(zuo)(zuo)不(bu)(bu)當等原因(yin)，播(bo)種(zhong)(zhong)(zhong)機(ji)(ji)(ji)經常會出(chu)現全(quan)機(ji)(ji)(ji)不(bu)(bu)播(bo)種(zhong)(zhong)(zhong)的(de)現象(xiang)，這(zhe)就需要農機(ji)(ji)(ji)手在(zai)使(shi)(shi)用時(shi)注意一些小細(xi)節，防止(zhi)這(zhe)些問題(ti)的(de)出(chu)現。播(bo)種(zhong)(zhong)(zhong)機(ji)(ji)(ji)不(bu)(bu)播(bo)種(zhong)(zhong)(zhong)主要是因(yin)為地(di)輪沒有接觸地(di)面。同樣播(bo)種(zhong)(zhong)(zhong)輪被雜草(cao)纏(chan)住，也會產(chan)生播(bo)種(zhong)(zhong)(zhong)輪不(bu)(bu)轉動，從(cong)而使(shi)(shi)播(bo)種(zhong)(zhong)(zhong)機(ji)(ji)(ji)的(de)不(bu)(bu)排種(zhong)(zhong)(zhong)。因(yin)此，農機(ji)(ji)(ji)手在(zai)使(shi)(shi)用播(bo)種(zhong)(zhong)(zhong)機(ji)(ji)(ji)時(shi)，一定要注意這(zhe)些問題(ti)，若播(bo)種(zhong)(zhong)(zhong)輪被雜草(cao)纏(chan)繞，應該將雜草(cao)清除掉再進行(xing)播(bo)種(zhong)(zhong)(zhong)，如果(guo)是鏈條(tiao)掉鏈，就要馬上停車熄(xi)火，將鏈條(tiao)修理(li)上，再進行(xing)工作(zuo)(zuo)。

　　3.避免各行(xing)播深不一致(zhi)

　　播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)在播(bo)種(zhong)(zhong)(zhong)(zhong)時(shi)，要盡量避免播(bo)深(shen)不一致。如果出現這種(zhong)(zhong)(zhong)(zhong)問題，會使所播(bo)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)深(shen)度不一致，過淺會使種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)干(gan)燥，可能由于缺水(shui)而死亡;過深(shen)會使種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)出土(tu)困難，從而不易生(sheng)長(chang)。產生(sheng)種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)播(bo)深(shen)不一致的(de)原因(yin)是土(tu)質的(de)硬度不均勻，或者農(nong)機(ji)手沒有(you)根據土(tu)壤情況(kuang)在作業前對播(bo)種(zhong)(zhong)(zhong)(zhong)機(ji)進(jin)行相(xiang)應的(de)調整，因(yin)此，農(nong)機(ji)手在操作時(shi)，應該對土(tu)質進(jin)行檢(jian)測(ce)，以確(que)保播(bo)種(zhong)(zhong)(zhong)(zhong)的(de)質量。
