               1) 耕深及其穩定性根據微耕機空間姿勢和土壤外表位置,依照國標的取樣辦法,每個行程左、右各測定10點的耕深,丈量值在計算機上可實時顯現、保管并畫出土攘耕深表示圖。 微耕機

               
               2) 耕寬及其穩定性測定時與耕深測點相對應。計算均勻值和規范差,并以規范差的值表示其平整度。根據微耕機空間姿勢,依照國標的取樣辦法,每個行程左、右各測定10點的耕寬,丈量值在計算機上可實時顯現、保管并畫出土壤耕寬表示圖。

               
              3) 土壤平整度在測定土壤膨松度時在耕前和耕后地表線上過高點作一程度線為基準線,在其恰當位置上取一定寬度(與樣機耕寬相當),分紅十等分,并在等分點上作垂線與基準線相交,量出地表線上各交點至基準線得間隔。依據土壤外表外形測得的數據,選擇一組,計算均勻值和規范差,并以規范差的值表示其平整度。

               
               
              4) 碎土率依據土壤外表圖象,剖析有色土壤的大小集中水平計算土壤碎土率。

               
               
              5) 掩蓋率依據土壤外表圖象,參照《GB/T5668-2008旋耕機》中規則的掩蓋率丈量辦法,剖析耕后外表可見有色土壤的面積,得出土壤掩蓋率。

               
               
              6) 土壤疏松度依據土壤外表外形數據,參照《GB/T5668-2008旋耕機》中規則的土壤疏松度的計算辦法,剖析耕層土壤的截面面積,得出土壤疏松度。
