　　【農(nóng)機網(wǎng) 熱點關注】 植保無人機施藥操作方便，作業(yè)效率高，已成為防控農(nóng)作物病蟲害的重要手段，但在使用中應注意以下問題：
 
　　1.施藥環(huán)境安全。作業(yè)前調(diào)查周邊環(huán)境，確保所在區(qū)域符合無人機作業(yè)條件，綜合評估潛在風險，防止霧滴飄移造成非靶標有益生物毒害和周邊敏感作物藥害。
 
　　2.作業(yè)參數(shù)設定。根據(jù)病蟲害發(fā)生種類、部位及為害程度，以及作物種類和生育期，藥劑助劑品種等，設定單位面積施藥液量，選擇適用的植保無人飛機機型，供選擇的機型包括多旋翼和單旋翼，設定合適的飛行高度、速度和有效噴幅等參數(shù)，并進行規(guī)劃航線。
 
　　3.藥劑劑型選擇。優(yōu)先選擇植保無人飛機專用劑型，其次是微乳劑、可溶液劑、懸浮劑、干懸浮劑、水乳劑、乳油、油劑等劑型，或高分散度的可濕性粉劑和水分散粒劑，以免堵塞噴頭影響噴霧和防治效果。
 
　　4.藥劑的配制。嚴格按照標簽說明用藥，不要私自加大用藥量和藥液濃度，采用二次稀釋法配藥，并現(xiàn)混現(xiàn)用；藥液中添加適量的噴霧助劑并混合均勻，用于改善農(nóng)藥藥液性能，提高霧滴沉降、抗飄移、抗蒸發(fā)等性能。
 
　　5.作業(yè)氣象條件。建議風力三級以內(nèi)、溫度12℃-30℃、相對濕度40%以上開展施藥作業(yè)。
 
　　6.施藥作業(yè)安全。要提前設立警示牌，廣播告知作業(yè)時間，作業(yè)區(qū)域禁止無關人員進入；無人機起降作業(yè)時，遠離障礙物和人員；作業(yè)人員應穿戴必要的防護用品，避免處在噴霧的下風位，作業(yè)時禁止吸煙和飲食。
 
　　7.作業(yè)效果巡查。施藥防治后，跟蹤調(diào)查飛防作業(yè)質量和防治效果，對防治效果不好的田塊及時進行補防。
