2.不(bu)能(neng)隨意混(hun)(hun)用(yong)(yong)。很(hen)多菜農(nong)(nong)在使用(yong)(yong)植物(wu)生(sheng)長(chang)(chang)(chang)調節劑時(shi),為圖省事,常(chang)將其(qi)隨意與化肥、殺(sha)蟲(chong)劑、殺(sha)菌(jun)劑等(deng)混(hun)(hun)用(yong)(yong)。植物(wu)生(sheng)長(chang)(chang)(chang)調節劑與化肥、農(nong)(nong)藥等(deng)物(wu)質能(neng)否混(hun)(hun)用(yong)(yong),必(bi)須在認真(zhen)閱讀(du)使用(yong)(yong)說明并經過試(shi)驗后(hou)才能(neng)確定,否則(ze)不(bu)僅達不(bu)到促進(jin)生(sheng)長(chang)(chang)(chang)或保花保果、補充肥料的作(zuo)用(yong)(yong),反(fan)而會因(yin)混(hun)(hun)合(he)不(bu)當出現藥害(hai)。比如:乙烯利藥液通常(chang)呈酸性,不(bu)能(neng)與堿性物(wu)質混(hun)(hun)用(yong)(yong);胺鮮酯遇堿易分解,不(bu)能(neng)與堿性農(nong)(nong)藥、化肥混(hun)(hun)用(yong)(yong)。
3.使(shi)(shi)用(yong)(yong)(yong)方法要(yao)(yao)(yao)得當。有(you)的菜農在使(shi)(shi)用(yong)(yong)(yong)植物(wu)生長調節劑前(qian),常(chang)常(chang)不認(ren)真閱(yue)讀使(shi)(shi)用(yong)(yong)(yong)說明,而是(shi)將植物(wu)生長調節劑直接兌水使(shi)(shi)用(yong)(yong)(yong)。是(shi)否能(neng)直接兌水一定要(yao)(yao)(yao)看(kan)清楚,因(yin)為(wei)有(you)的植物(wu)生長調節劑不能(neng)直接在水中溶解,若(ruo)不事先配制(zhi)(zhi)成母液后再配制(zhi)(zhi)成需要(yao)(yao)(yao)的濃(nong)度,藥(yao)劑很難混勻,會(hui)影響(xiang)使(shi)(shi)用(yong)(yong)(yong)效(xiao)果。因(yin)此(ci),使(shi)(shi)用(yong)(yong)(yong)時一定要(yao)(yao)(yao)嚴(yan)格按照(zhao)使(shi)(shi)用(yong)(yong)(yong)說明稀(xi)釋。
4.生(sheng)長(chang)(chang)(chang)調(diao)節(jie)(jie)劑(ji)(ji)不(bu)(bu)能代(dai)(dai)替肥料(liao)施(shi)用(yong)。生(sheng)長(chang)(chang)(chang)調(diao)節(jie)(jie)劑(ji)(ji)不(bu)(bu)是植物(wu)營養物(wu)質(zhi),只能起(qi)調(diao)控生(sheng)長(chang)(chang)(chang)的作用(yong),不(bu)(bu)能代(dai)(dai)替肥料(liao)使用(yong),在水肥條件不(bu)(bu)充足的情(qing)況下,噴施(shi)過(guo)多的植物(wu)生(sheng)長(chang)(chang)(chang)調(diao)節(jie)(jie)劑(ji)(ji)反而有害。因此(ci),在發現植物(wu)生(sheng)長(chang)(chang)(chang)不(bu)(bu)良時,首先要加強施(shi)肥澆水等管理,在此(ci)基礎(chu)上(shang)使用(yong)生(sheng)長(chang)(chang)(chang)調(diao)節(jie)(jie)劑(ji)(ji)才能有效地發揮(hui)其(qi)作用(yong)。
5.植物生長調節劑屬(shu)于農(nong)藥類(lei)產(chan)(chan)品(pin),產(chan)(chan)品(pin)包裝必須有正(zheng)規”農(nong)藥三證“,標示帶為黃色。
6.嚴格按照說明書(shu)使用,做好防護措(cuo)施,防止(zhi)對人、畜(chu)及(ji)引用水安全造(zao)成(cheng)影響。
