【摘要(yao)】：[目(mu)的(de)]以期獲得各種農(nong)用(yong)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)在(zai)(zai)植(zhi)(zhi)(zhi)物(wu)靶標上(shang)的(de)潤濕鋪展效(xiao)(xiao)(xiao)果(guo),并(bing)(bing)為田間應用(yong)提供理(li)論(lun)指(zhi)導。[方法]對4種助劑(ji):有(you)機(ji)硅類(lei)(lei)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)Silwet 408和(he)Silwet~?L-7608、非離子型增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)SYNPERONIC 13/6.5-LQ-(TH)及(ji)植(zhi)(zhi)(zhi)物(wu)源(yuan)類(lei)(lei)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)LI-700的(de)靜(jing)態(tai)(tai)表面張力及(ji)動(dong)態(tai)(tai)接(jie)觸(chu)角(jiao)進(jin)行研究。[結果(guo)]通過(guo)測定上(shang)述4種農(nong)用(yong)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)500、1000倍水溶液(ye)液(ye)滴在(zai)(zai)水稻(dao)葉(xie)片上(shang)的(de)動(dong)態(tai)(tai)接(jie)觸(chu)角(jiao)(DCA)及(ji)靜(jing)態(tai)(tai)表面張力(EST)，探討了DCA和(he)EST對藥液(ye)在(zai)(zai)水稻(dao)葉(xie)片上(shang)的(de)潤濕性和(he)鋪展的(de)影響(xiang)。[結論(lun)]有(you)機(ji)硅類(lei)(lei)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)Silwet 408和(he)Silwet~?L-7608的(de)靜(jing)態(tai)(tai)表面張力及(ji)動(dong)態(tai)(tai)接(jie)觸(chu)角(jiao)最(zui)小，非離子型增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)SYNPERONIC 13/6.5-LQ-(TH)的(de)次(ci)之(zhi)，植(zhi)(zhi)(zhi)物(wu)源(yuan)增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)LI-700的(de)最(zui)大。但由于各種增(zeng)(zeng)效(xiao)(xiao)(xiao)劑(ji)的(de)增(zeng)(zeng)效(xiao)(xiao)(xiao)機(ji)理(li)不(bu)同,因(yin)而(er)其在(zai)(zai)與農(nong)藥桶混后所表現出的(de)增(zeng)(zeng)效(xiao)(xiao)(xiao)作用(yong)與實(shi)驗室理(li)論(lun)并(bing)(bing)非完(wan)全一致。
