中文摘要:为探索雾滴在不同结构叶片表面沉积效果差异,试验研究138.2、176.5、209.1、235.1和283.7μm 5个粒径雾滴在毛刺、蜡质和粗糙3种表面的沉积效果,分析了各类叶片表面在与水平面呈0°、15°、30°、45°、60°和75°6个夹角时的沉积差异。对叶面结构、叶片倾角和雾滴粒径3个因素的影响程度差异进行了正交试验。结果表明,喷量相同的情况下,雾滴在蜡质及粗糙叶面沉积率随雾滴粒径增大而减小,在毛刺叶片表面,当雾滴粒径大于231.5μm时,药液沉积率随雾滴粒径增大而减小的趋势更为明显。在毛刺和粗糙叶片表面,药液沉积率随叶面倾角增大而减小;而在蜡质叶面,倾角大于45°时,沉积率会产生一次突增并超过较小倾角时的雾滴沉积率。叶片倾角对雾滴沉积率影响最大,叶面结构次之,雾滴粒径影响不显著。

Abstract:In order to investigate the droplet deposition on hairy, waxy and rough plant leaves, a series of experiments were schemed with a combination of five droplet sizes of 138.2 μm, 176.5μm, 209.1 μm, 235.1 μm and 283.7 μm and six leaf dip angles of 0°, 15°, 30°, 45°, 60° and 75°. The orthogonal tests were used to analyze the cross influences among plant leaf surface structures, leaf surface dips and droplet sizes. The experiment results showed, under same spray volume, droplet deposition tended to decline with the increase of the droplet sizes in general. On the hairy structure leaf surface, a turning point turn up after which the deposition decrease was getting larger sharply when the droplet size was over 231.5μm. On hairy and rough surfaces, droplet deposition increased with the surface dip’s reducing. However, on the waxy leaf surfaces, a positive deposition mutation might take place as the surface dip exceeded 45°. The study concluted that leaf dips had more influence on droplet deposition than leaf surface structures while the droplet size made little effect on it. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
