大棚微耕机技术工艺流程
时间:2012-11-12 来源:本站 作者:管理员
大棚微耕机技术工艺流程主要包括机具准备、地块准备、耕作及耕作后修补等环节,具体如下图
 
1.机具准备
 
确定作业机具,对机具检查维修;根据土质、土壤比阻选择合适的刀具;加足燃油、润滑油和水;确定作业线路。棚内作业的线路一般有三种:沿着棚子长度方向作业;沿着棚子宽度方向作业和混合作业;沿长度方向作业:机组效率高,回转少,但池埂子破坏严重,修埂工作量大,而且耕深不易控制、深浅不一。沿宽度方向作业:作业质量好,池埂破坏少,机具容易控制,深浅一致,但机组回转较多,效率低。沿宽度方向作业又分全幅作业和半幅作业。全幅作业是从棚子一边耕到另一边,一次耕完成:半幅作业是从中间开始,分别向棚边耕,到棚边倒车回到中间再耕另一池子。混合耕作,即从棚子中间沿宽度方向作业,棚边沿长度方向作业,这样能够弥补沿长、宽方向作业的不足,尽量减少对池埂的破坏、减少池埂的修补用工和提高机组的利用率。
 
1.地块的准备
 
首先要彻底清理棚内的残株杂物,清理障碍物,尤其是地表以下隐藏的障碍物。对于隐藏又不能清除的障碍物必须做好明显标记;棚边缘的棚膜应当卷起1m高左右,若施肥可将肥料(化肥或农家肥)散施在地表,待耕作时翻埋到土壤中。
 
2.耕翻作业和修补
 
经过前边的准备之后进行耕作。耕作后必须用人工对机械没有耕作到的地方和池埂进行修补。
