導(dǎo)讀：5月11日—15日，湖北省荊州市石首市農(nóng)業(yè)技術(shù)推廣中心在高陵鎮(zhèn)流合垸村軒揚(yáng)農(nóng)機(jī)專業(yè)合作社，開(kāi)展了油菜兩段機(jī)收與聯(lián)合收割的對(duì)比試驗(yàn)。

　　【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】為了減少油菜機(jī)收損失，5月11日—15日，湖北省荊州市石首市農(nóng)業(yè)技術(shù)推廣中心在高陵鎮(zhèn)流合垸村軒揚(yáng)農(nóng)機(jī)專業(yè)合作社，開(kāi)展了油菜兩段機(jī)收與聯(lián)合收割的對(duì)比試驗(yàn)。
 
　　5月11日，技術(shù)人員選擇了一塊長(zhǎng)勢(shì)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(jī)割了一部分，也放在田里晾曬；還留了一部分等待聯(lián)合收割。
 
　　5月15日，用人工把用人工割曬的菜籽打出來(lái)；用聯(lián)合收割機(jī)采用撿拾脫粒的方式把菜籽收起來(lái)；用同款的聯(lián)合收割機(jī)把上次留下來(lái)的一部分油菜采用聯(lián)合收割的方式把菜籽收起來(lái)。然后計(jì)算畝產(chǎn)量，用兩段收獲的畝產(chǎn)量、聯(lián)合收割的畝產(chǎn)量分別與人工收獲的畝產(chǎn)量進(jìn)行對(duì)比，計(jì)算損失率。試驗(yàn)結(jié)果表明，兩段機(jī)收要比聯(lián)合收割減少損失7.8%。
