  【農(nóng)機網(wǎng) 地方農(nóng)機】根據(jù)山西省農(nóng)機發(fā)展中心《大豆玉米帶狀復(fù)合種植機械化生產(chǎn)對比試驗方案》要求,為更好推動山西省大豆玉米兼容協(xié)調(diào)發(fā)展,發(fā)揮農(nóng)機化技術(shù)在生產(chǎn)中的優(yōu)勢,通過科學(xué)試驗,探索適宜不同地域的機械化復(fù)合種植模式。近日,山西省晉城市農(nóng)機發(fā)展中心聯(lián)合澤州縣、陵川縣、沁水縣農(nóng)機部門成立了聯(lián)合測試組,深入全市各項目承擔(dān)主體開展了一系列對比試驗工作。
 
  本次試驗內(nèi)容主要包括:1.測量大豆玉米帶狀復(fù)合種植不同模式、相對應(yīng)大豆玉米清種的植株性狀指標(biāo),合理計算大豆和玉米構(gòu)成產(chǎn)量的主要因素指標(biāo)。2.研判機械化收獲裝備與當(dāng)?shù)卮蠖褂衩撞煌N植模式的匹配程度,對新購置的大豆、玉米收獲機型進行先進性、適應(yīng)性及安全性試驗考核,并對用戶使用情況進行跟蹤調(diào)查;3.分析計算大豆玉米帶狀復(fù)合種植不同模式、相對應(yīng)大豆玉米清種的成本及產(chǎn)出,進行經(jīng)濟效益分析。
 
  試驗流程包括基本情況調(diào)查、觀察地塊特點、機型考核、現(xiàn)場測量取樣、市內(nèi)測量計算、撰寫試驗報告等步驟。大豆相關(guān)測算指標(biāo)包括結(jié)莢高度、株高、主莖節(jié)數(shù)、主莖節(jié)間長度、單株莢數(shù)、單株秕莢數(shù)、單株粒數(shù)、畝株數(shù)、千粒重、理論產(chǎn)量等。玉米相關(guān)測算指標(biāo)包括結(jié)穗高度、株高、莖粗、近地節(jié)間長、棒三葉夾角、畝株數(shù)及畝穗數(shù)、玉米穗粒數(shù)、千粒重、理論畝產(chǎn)量等。
 
  通過本次對比試驗,優(yōu)選出適宜的大豆玉米帶狀復(fù)合種植機械化生產(chǎn)模式,為推廣大豆玉米帶狀復(fù)合種植機械化生產(chǎn)、實現(xiàn)“玉米不減產(chǎn),多收一季大豆”的目標(biāo)提供科學(xué)客觀依據(jù),有望進一步促進農(nóng)業(yè)增產(chǎn)、農(nóng)民增收。
