南方水稻灌漿成熟期無人機(jī)葉面噴肥技術(shù)指導(dǎo)意見

導(dǎo)讀：今年南方部分地區(qū)秋季高溫天氣持續(xù)，可能會(huì)影響水稻灌漿，導(dǎo)致結(jié)實(shí)率下降、產(chǎn)量降低，可適時(shí)采用無人機(jī)噴施葉面肥，促進(jìn)水稻高產(chǎn)穩(wěn)產(chǎn)。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 灌漿期是水稻產(chǎn)量和品質(zhì)形成的關(guān)鍵時(shí)期，灌漿過程易受溫度、水肥條件等因素影響。今年南方部分地區(qū)秋季高溫天氣持續(xù)，可能會(huì)影響水稻灌漿，導(dǎo)致結(jié)實(shí)率下降、產(chǎn)量降低，可適時(shí)采用無人機(jī)噴施葉面肥，促進(jìn)水稻高產(chǎn)穩(wěn)產(chǎn)。
 
　　適用區(qū)域
 
　　適用于南方遭遇持續(xù)高溫天氣的水稻主產(chǎn)區(qū)。
 
　　技術(shù)要點(diǎn)
 
　　（一）無人機(jī)選擇
 
　　選擇當(dāng)?shù)剞r(nóng)業(yè)生產(chǎn)中普遍使用的農(nóng)用無人機(jī)，有效負(fù)載50公斤以上為宜。水稻葉面噴施時(shí)有效播撒幅寬3—5米、作業(yè)高度3—4米、飛行速度4—6米/秒，每畝施肥量誤差不超過5%。無人機(jī)應(yīng)具備自主作業(yè)、智能避障、漏堵報(bào)警、實(shí)時(shí)監(jiān)控和軌跡記錄等功能。
 
　　（二）肥料選擇
 
　　應(yīng)選擇溶解性好的氮磷鉀和中微量元素肥料，如磷酸二氫鉀、七水硫酸鎂、六水硝酸鎂、硫酸鋅等，或大量元素水溶肥料、中量元素水溶肥料、微量元素水溶肥料、含氨基酸水溶肥料、含腐植酸水溶肥料、有機(jī)水溶肥料等。成熟期可與乙酸銨、乙烯利、表面活性劑(如吐溫20)等配合施用。
 
　　（三）作業(yè)程序
 
　　1、使用無人機(jī)噴肥前，根據(jù)作業(yè)條件設(shè)置無人機(jī)的飛行高度、速度、噴幅、航線方向、噴灑量、霧化顆粒大小等參數(shù)并試飛，試飛正常后方可進(jìn)行飛行作業(yè)。
 
　　2、葉面噴肥作業(yè)前，按照建議的濃度用清水溶解肥料，待全部溶解后，靜置3—5分鐘，取清液噴施。
 
　　3、葉面噴肥作業(yè)應(yīng)在風(fēng)力小于3級的陰天或晴天傍晚進(jìn)行，防止灼傷稻苗，確保肥效。
 
　　4、追肥作業(yè)后，應(yīng)記錄無人機(jī)作業(yè)情況。葉面噴肥后若遇雨，應(yīng)重新噴施。
 
　　5、噴施作業(yè)結(jié)束后，觀察水稻長勢決定是否再次噴施。前后兩次噴施至少間隔7—10天，不可盲目噴施造成肥害。
 
　　注意事項(xiàng)
 
　　1、視苗情長勢和天氣情況，可在灌漿期和成熟期各噴施1次。
 
　　2、無人機(jī)操作人員應(yīng)持證上崗，做好防護(hù)措施。無人機(jī)轉(zhuǎn)運(yùn)時(shí)應(yīng)遠(yuǎn)離，禁止觸摸。
 
　　3、肥料混合噴施時(shí)應(yīng)按照品種特性和使用說明進(jìn)行混配。
 
　　4、嚴(yán)格遵守?zé)o人機(jī)飛行相關(guān)法律法規(guī)。
