黑龍江播種機使用時注(zhu)意(yi)事項：
1.播種的要求
播(bo)(bo)種(zhong)(zhong)機在(zai)播(bo)(bo)種(zhong)(zhong)時，應按照(zhao)種(zhong)(zhong)子的(de)(de)(de)特(te)點，對(dui)其進行播(bo)(bo)種(zhong)(zhong)。如播(bo)(bo)種(zhong)(zhong)的(de)(de)(de)行距應該控制在(zai)20厘米左右，不(bu)能(neng)過(guo)寬也(ye)(ye)不(bu)能(neng)過(guo)窄。播(bo)(bo)種(zhong)(zhong)深度應控制在(zai)1.5—3.0厘米，但(dan)是(shi)也(ye)(ye)要(yao)(yao)考(kao)慮到(dao)特(te)殊(shu)情況，不(bu)同的(de)(de)(de)土(tu)(tu)壤(rang)(rang)播(bo)(bo)種(zhong)(zhong)的(de)(de)(de)深度也(ye)(ye)不(bu)同，土(tu)(tu)壤(rang)(rang)偏旱，播(bo)(bo)深就要(yao)(yao)略深一(yi)點，這樣(yang)可(ke)以(yi)防止(zhi)種(zhong)(zhong)子播(bo)(bo)淺，土(tu)(tu)壤(rang)(rang)過(guo)干而不(bu)能(neng)生(sheng)長(chang)。因(yin)此，農機手在(zai)播(bo)(bo)種(zhong)(zhong)時，一(yi)定要(yao)(yao)充分考(kao)慮種(zhong)(zhong)子、土(tu)(tu)壤(rang)(rang)等情況，確保種(zhong)(zhong)子的(de)(de)(de)健康成(cheng)長(chang)。
2.播種機故障的注意(yi)事項
由(you)于操作(zuo)不(bu)當等(deng)原因(yin)(yin)，播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)經常會(hui)出(chu)現全機(ji)不(bu)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)的現象，這(zhe)就需(xu)要農機(ji)手(shou)在使(shi)用時注意(yi)(yi)一(yi)些(xie)小細(xi)節，防止這(zhe)些(xie)問(wen)題(ti)的出(chu)現。播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)不(bu)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)主要是(shi)因(yin)(yin)為(wei)地輪沒有接觸地面。同樣播(bo)(bo)(bo)種(zhong)(zhong)(zhong)輪被(bei)(bei)雜(za)草纏(chan)住(zhu)，也會(hui)產生(sheng)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)輪不(bu)轉動(dong)，從而使(shi)播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)的不(bu)排(pai)種(zhong)(zhong)(zhong)。因(yin)(yin)此(ci)，農機(ji)手(shou)在使(shi)用播(bo)(bo)(bo)種(zhong)(zhong)(zhong)機(ji)時，一(yi)定(ding)要注意(yi)(yi)這(zhe)些(xie)問(wen)題(ti)，若播(bo)(bo)(bo)種(zhong)(zhong)(zhong)輪被(bei)(bei)雜(za)草纏(chan)繞，應該將(jiang)雜(za)草清除掉再(zai)進(jin)行播(bo)(bo)(bo)種(zhong)(zhong)(zhong)，如果(guo)是(shi)鏈(lian)條掉鏈(lian)，就要馬上停車熄火，將(jiang)鏈(lian)條修理上，再(zai)進(jin)行工(gong)作(zuo)。
3.避(bi)免(mian)各行播深(shen)不(bu)一致
播種(zhong)機(ji)在(zai)播種(zhong)時，要盡量(liang)避免播深(shen)(shen)不(bu)一致。如果出現這(zhe)種(zhong)問題，會(hui)(hui)使(shi)所播種(zhong)子深(shen)(shen)度(du)不(bu)一致，過淺會(hui)(hui)使(shi)種(zhong)子干(gan)燥，可能由(you)于缺水(shui)而(er)死亡;過深(shen)(shen)會(hui)(hui)使(shi)種(zhong)子出土(tu)困(kun)難(nan)，從而(er)不(bu)易生(sheng)長(chang)。產生(sheng)種(zhong)子播深(shen)(shen)不(bu)一致的原因(yin)是土(tu)質的硬度(du)不(bu)均勻，或者農機(ji)手沒有根(gen)據土(tu)壤情況(kuang)在(zai)作(zuo)業前對(dui)播種(zhong)機(ji)進行相應的調整(zheng)，因(yin)此，農機(ji)手在(zai)操作(zuo)時，應該對(dui)土(tu)質進行檢測(ce)，以確保播種(zhong)的質量(liang)。
