    導讀：5月11日—15日，湖北省荊州市石首市農業技術推廣中心在高陵鎮流合垸村軒揚農機專業合作社，開展了油菜兩段機收與聯合收割的對比試驗。

    　　【農機網 地方農機】為了減少油菜機收損失，5月11日—15日，湖北省荊州市石首市農業技術推廣中心在高陵鎮流合垸村軒揚農機專業合作社，開展了油菜兩段機收與聯合收割的對比試驗。
     
    　　5月11日，技術人員選擇了一塊長勢中等的水田油菜地，首先用人工割倒了一部分，放在田里晾曬；后用割曬機割了一部分，也放在田里晾曬；還留了一部分等待聯合收割。
     
    　　5月15日，用人工把用人工割曬的菜籽打出來；用聯合收割機采用撿拾脫粒的方式把菜籽收起來；用同款的聯合收割機把上次留下來的一部分油菜采用聯合收割的方式把菜籽收起來。然后計算畝產量，用兩段收獲的畝產量、聯合收割的畝產量分別與人工收獲的畝產量進行對比，計算損失率。試驗結果表明，兩段機收要比聯合收割減少損失7.8%。
