宽喷幅风送式喷雾机在果树冠层中喷雾有效性及雾滴穿透性试验研究
风送式喷雾可以有效地抵御自然风的干扰,减少雾滴的漂移,其喷雾有效性及雾滴的穿透性直接影响着喷雾机的喷雾性能。以宽喷幅风送式喷雾机为试验平台,用0.1%的罗丹明B为示踪剂,对靶标树进行了喷雾试验,研究宽喷幅风送式喷雾机雾滴沉积的有效性与穿透性。结果表明：喷雾雾滴在树冠前冠面及内膛均有较高的效率,在靶标树的前冠面、中膛、后冠面和距离树冠后方10 cm的外截面等4个截面上都有雾滴沉积,喷雾有效率分别为100%、86.2%、48.3%和62.1%;树冠前冠面、中膛、后冠面雾滴沉积量分别为0.028、0.007、0.003 m L,树冠前后地面上有明显的雾滴沉积,地面采样点上的沉积量分别为0.044、0...

In order to research the spraying validity and droplets penetration, thes experiment was carried out via a wide-swath air-blast sprayer as the test platform, while 0.1% Rhodamine B as a tracer. Spraying validity test results showed that it had a better spraying validity in the front surface and intermediate section of the target tree canopy, and there was all droplet deposition in the front surface, intermediate section, back surface of the canopy and the section rearwa |
