              大棚微耕機技術工藝流程
              時間:2012-11-12 來源:本站 作者:管理員
              大棚微耕機技術工藝流程主要包括機具準備、地塊準備、耕作及耕作后修補等環節,具體如下圖
               
              1.機具準備
               
              確定作業機具,對機具檢查維修;根據土質、土壤比阻選擇合適的刀具;加足燃油、潤滑油和水;確定作業線路。棚內作業的線路一般有三種:沿著棚子長度方向作業;沿著棚子寬度方向作業和混合作業;沿長度方向作業:機組效率高,回轉少,但池埂子破壞嚴重,修埂工作量大,而且耕深不易控制、深淺不一。沿寬度方向作業:作業質量好,池埂破壞少,機具容易控制,深淺一致,但機組回轉較多,效率低。沿寬度方向作業又分全幅作業和半幅作業。全幅作業是從棚子一邊耕到另一邊,一次耕完成:半幅作業是從中間開始,分別向棚邊耕,到棚邊倒車回到中間再耕另一池子?;旌细?,即從棚子中間沿寬度方向作業,棚邊沿長度方向作業,這樣能夠彌補沿長、寬方向作業的不足,盡量減少對池埂的破壞、減少池埂的修補用工和提高機組的利用率。
               
              1.地塊的準備
               
              首先要徹底清理棚內的殘株雜物,清理障礙物,尤其是地表以下隱藏的障礙物。對于隱藏又不能清除的障礙物必須做好明顯標記;棚邊緣的棚膜應當卷起1m高左右,若施肥可將肥料(化肥或農家肥)散施在地表,待耕作時翻埋到土壤中。
               
              2.耕翻作業和修補
               
              經過前邊的準備之后進行耕作。耕作后必須用人工對機械沒有耕作到的地方和池埂進行修補。
