導(dǎo)讀：近日，上海市浦東新區(qū)農(nóng)機站組織科技人員參加了市農(nóng)機站舉辦的2022年“三秋”水稻機收減損技術(shù)專題培訓(xùn)會。

　　【農(nóng)機網(wǎng) 地方農(nóng)機】減損就是增產(chǎn)，降耗就是增收。近日，上海市浦東新區(qū)農(nóng)機站組織科技人員參加了市農(nóng)機站舉辦的2022年“三秋”水稻機收減損技術(shù)專題培訓(xùn)會，根據(jù)會議關(guān)于做好全市水稻機收減損監(jiān)測工作任務(wù)要求，區(qū)農(nóng)機站組織黨員和年輕科技人員，對惠南鎮(zhèn)遠東村的試驗田塊進行水稻聯(lián)合收割機收獲損失率實地測定。
 
　　試驗田水稻品種為花優(yōu)14，收獲機型為久保田888，監(jiān)測小組嚴格按照《水稻聯(lián)合收割機收獲損失率測定方法》，待收獲作業(yè)后，在收割機穩(wěn)定作業(yè)區(qū)域，往返2個行程內(nèi)隨機選取2個取樣區(qū)，每個區(qū)域為沿聯(lián)合收割機前進方向長度1m，寬幅為聯(lián)合收割機工作寬幅。經(jīng)收集2個取樣區(qū)內(nèi)夾雜在秸稈和雜余內(nèi)的籽粒、穗頭(不含超出取樣區(qū)域部分)上未脫凈的籽粒和掉落在地面的籽粒，脫粒去雜后稱其質(zhì)量(忽略自然落粒)分別為20.3g和29.8g，平均損失量為25.05g。經(jīng)測產(chǎn)、計算，該試驗田水稻產(chǎn)量達到610.8kg/畝，損失率為1.59%較為理想。
 
　　三秋”期間，浦東新區(qū)認真做好《水稻機收減損技術(shù)指導(dǎo)意見》的修訂與宣貫，從作業(yè)前準備、機收作業(yè)質(zhì)量要求、減少機收損失技術(shù)等方面加強指導(dǎo)，切實提高大家的收割減損意識，規(guī)范機具操作能力，進一步降低機收損失率和破損率，保障浦東新區(qū)秋糧顆粒歸倉，全力奪取豐產(chǎn)豐收。
