導(dǎo)讀：近日，山西省農(nóng)業(yè)機(jī)械發(fā)展中心特制定并印發(fā)《大豆玉米帶狀復(fù)合種植機(jī)械化生產(chǎn)對(duì)比試驗(yàn)方案》。
【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】玉米、大豆是我國(guó)重要的糧油作物，為解決大豆進(jìn)口量過(guò)高，玉米大豆?fàn)幍孛芡怀龅葐?wèn)題，國(guó)家加大對(duì)大豆玉米間作新農(nóng)藝推廣的支持力度，在包括山西在內(nèi)的16個(gè)省份大面積示范推廣大豆玉米帶狀復(fù)合種植技術(shù)，實(shí)現(xiàn)在同一塊土地上大豆玉米和諧共生、一季雙收，穩(wěn)玉米、增大豆的生產(chǎn)目標(biāo)。
為響應(yīng)中央大力實(shí)施大豆和油料產(chǎn)能提升工程號(hào)召，推廣大豆玉米帶狀復(fù)合種植技術(shù)，優(yōu)選出適宜山西省大豆玉米帶狀復(fù)合
種植機(jī)化生產(chǎn)模式，實(shí)現(xiàn)“玉米不減產(chǎn)，多收一季大豆”的目標(biāo)，近日，山西省農(nóng)業(yè)機(jī)械發(fā)展中心特制定并印發(fā)《大豆玉米帶狀復(fù)合
種植機(jī)械化生產(chǎn)對(duì)比試驗(yàn)方案》。
此方案旨在為更好的推動(dòng)山西省大豆玉米兼容發(fā)展、協(xié)調(diào)發(fā)展，發(fā)揮農(nóng)機(jī)化技術(shù)在生產(chǎn)中的優(yōu)勢(shì)，進(jìn)一步促進(jìn)農(nóng)業(yè)增產(chǎn)、農(nóng)民增收，有必要對(duì)大豆玉米帶狀復(fù)合種植不同模式、清種模式機(jī)械化生產(chǎn)情況進(jìn)行對(duì)比試驗(yàn)，通過(guò)科學(xué)試驗(yàn)，探索適宜山西省不同地域的機(jī)械化復(fù)合種植模式。
該方案要求全省48個(gè)大豆玉米復(fù)合種植縣均要積極主動(dòng)做好試驗(yàn)工作，選擇本區(qū)域內(nèi)種植模式面積較大、兩種模式以上的地塊進(jìn)行測(cè)試，與當(dāng)?shù)厍宸N大豆、玉米進(jìn)行對(duì)比；另外，省中心在測(cè)試期間將分赴陽(yáng)高縣、陽(yáng)曲縣、孝義市、安澤縣和澤州縣等地進(jìn)行實(shí)地技術(shù)指導(dǎo)及跟蹤測(cè)試。
按照各縣實(shí)際情況可選用專用大豆收獲機(jī)、2行玉米收獲機(jī)進(jìn)行考核。 試驗(yàn)內(nèi)容——
測(cè)量大豆玉米帶狀復(fù)合種植不同模式、相對(duì)應(yīng)大豆玉米清種的植株性狀指標(biāo)，合理計(jì)算大豆的畝株數(shù)、單株粒數(shù)、千粒重和玉米的畝穗數(shù)、穗粒數(shù)、千粒重等構(gòu)成產(chǎn)量的主要因素指標(biāo)；
研判機(jī)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(duì)新購(gòu)置的大豆、玉米收獲機(jī)型進(jìn)行先進(jìn)性、適應(yīng)性及安全性試驗(yàn)考核，并對(duì)用戶使用情況進(jìn)行跟蹤調(diào)查；
分析計(jì)算大豆玉米帶狀復(fù)合種植不同模式、相對(duì)應(yīng)大豆玉米清種的成本及產(chǎn)出，進(jìn)行經(jīng)濟(jì)效益分析。(具體試驗(yàn)標(biāo)準(zhǔn)相關(guān)具體內(nèi)容可點(diǎn)擊下載附件查看)
另悉，2022年9月15日，山西省農(nóng)業(yè)機(jī)械發(fā)展中心還印發(fā)了《大豆玉米帶狀復(fù)合種植機(jī)收減損技術(shù)指導(dǎo)意見(jiàn)》，進(jìn)一步加強(qiáng)大豆玉米帶狀復(fù)合種植機(jī)械化收獲技術(shù)裝備支撐。通過(guò)此次對(duì)比試驗(yàn)，對(duì)于推廣大豆玉米帶狀復(fù)合種植技術(shù)、探索出適宜本土的大豆玉米帶狀復(fù)合種植機(jī)械化生產(chǎn)模式具有重要意義，同時(shí)有望進(jìn)一步促進(jìn)農(nóng)業(yè)增產(chǎn)、農(nóng)民增收。
