    摘要:

    研究了無(wú)人駕駛直升機(jī)航空噴霧參數(shù)對(duì)藥液霧滴沉積效果的影響,。使用紅外熱像儀與無(wú)人機(jī)聯(lián)用測(cè)試噴霧前,、后作物冠層溫度,,通過(guò)溫度變化率反映霧滴在水稻冠層的沉積效果,。結(jié)果表明:以霧滴沉積量與冠層溫度變化率為評(píng)價(jià)指標(biāo)得到的結(jié)果一致,,紅外熱成像技術(shù)可以準(zhǔn)確反映霧滴在水稻上的沉積規(guī)律,。WPH642型無(wú)人駕駛直升機(jī)作業(yè)時(shí)選取噴霧參數(shù)為:飛行高度2 m,、飛行速度1.5 m/s。

    Abstract:

    The influence of application parameters of unmanned aircraft on droplets deposition was researched. Temperature change rate was tested by thermal infrared imager to reflect the droplets deposit on rice canopy. The results showed that there was no difference with the droplets deposition and canopy temperature change rate as evaluation index. Thermal infrared imager could reflect the droplets deposit law exactly. The optimum application parameters of WPH642 unmanned aircraft were that flight altitude of 2m and flight velocity of 1.5 m/s. 
