導(dǎo)讀：大豆上應(yīng)重點關(guān)注漬澇、低溫冷害、早霜、病蟲害等災(zāi)害威脅，因地因苗、因時因災(zāi)，分類開展“一噴多促”。

　　【農(nóng)機網(wǎng) 科技創(chuàng)新】 目前我區(qū)大豆正處于結(jié)莢鼓粒期，是產(chǎn)量品質(zhì)形成的關(guān)鍵期，也是“一噴多促”的窗口期。將葉面肥、調(diào)節(jié)劑、抗逆劑、殺蟲殺菌劑等混合噴施，一次作業(yè)可實現(xiàn)促生長發(fā)育、促灌漿成熟、促災(zāi)后恢復(fù)、促產(chǎn)量提高等多重效應(yīng)，是大豆中后期有災(zāi)防災(zāi)、無災(zāi)增產(chǎn)的關(guān)鍵措施。大豆上應(yīng)重點關(guān)注漬澇、低溫冷害、早霜、病蟲害等災(zāi)害威脅，因地因苗、因時因災(zāi)，分類開展“一噴多促”。
 
　　一、藥肥選擇
 
　　當(dāng)前“一噴多促”以保莢、增粒重、促早熟為重點，選擇葉面噴施磷酸二氫鉀、中微量元素水溶肥。根據(jù)病蟲發(fā)生情況可混合施用殺菌劑或殺蟲劑，大豆殺菌劑可選用吡唑醚菌酯、嘧菌酯、吡唑醚菌酯·氟環(huán)唑、苯甲·丙環(huán)唑等；殺蟲劑可選擇氯蟲苯甲酰胺、溴氰菊酯、高效氯氟氰菊酯、甲維·毒死蜱等。受災(zāi)地塊可混合噴施生長調(diào)節(jié)劑，可選擇三十烷醇、蕓苔素內(nèi)酯、吲哚丁酸等。
 
　　二、科學(xué)噴施
 
　　1.時間上，作業(yè)時風(fēng)力應(yīng)在三級以內(nèi)、溫度不超過30℃，一般選擇在無雨天的上午9時前、下午4時后進行，避開正午高溫時段；如噴后24小時內(nèi)遇中到大雨，要及時補噴；可因地制宜選擇無人機夜間作業(yè)。
 
　　2.用量上，采用無人機作業(yè)時，每畝噴液量1.5升以上，并在藥液中添加適量的噴霧助劑，提高霧滴沉降、抗飄移、抗蒸發(fā)等性能。
 
　　3.作業(yè)上，植保無人機飛行速度控制在3—5米/秒，飛行高度根據(jù)無人機載重量進行調(diào)整，載重30升以下無人機飛行高度距大豆冠層2—3米，載重30升以上的為3.5—4.5米。
 
　　三、注意事項
 
　　一是選擇正規(guī)途徑購買藥肥。購買時先查驗經(jīng)營許可證，確保藥肥質(zhì)量有保證。
 
　　二是嚴格按照使用說明推薦劑量用藥，不可盲目加大藥量。藥劑配制要進行二次稀釋，藥肥溶解要充分，確?；炫渚鶆?，防止噴施過程中堵塞噴頭，影響噴施效果。
 
　　三是兩種或兩種以上藥劑混用時，需檢測是否發(fā)生拮抗現(xiàn)象，如有拮抗應(yīng)更換同類其它藥劑。
 
　　四是噴施作業(yè)前仔細檢修機械設(shè)備，試噴后正式作業(yè)，確保機械無故障、作業(yè)合格。
 
　　五是提前規(guī)劃好飛行線路，避免漏噴或重噴。田邊地頭、林帶周邊大型植保無人機無法作業(yè)到的地方，采用人工補噴。
 
　　六是作業(yè)前依照有關(guān)法規(guī)提前公告，綜合評估潛在風(fēng)險，作業(yè)時設(shè)立警示牌，防止噴霧霧滴飄移造成非靶標生物毒害和周邊作物藥害，大規(guī)模施藥前須開展小范圍試驗。
 
　　七是無人機起降作業(yè)時，應(yīng)遠離障礙物和人員，作業(yè)人員應(yīng)穿戴必要的防護用品，避開噴霧下風(fēng)位，嚴禁在施藥區(qū)穿行，作業(yè)時禁止吸煙及飲食。
