【摘要】 本文针对风送式喷雾机在果园病虫害防治施药技术中大规模使用,综述了风送式喷雾机具有喷幅大、雾滴均匀性好、农药使用效率高和受环境制约少等优点,介绍了喷幅是风送式喷雾机重要性能指标之一,喷洒的均匀性及穿透性、树冠雾滴沉降率、沉降分布规律等都是评价喷雾效果的重要指标。为了揭示果园风送喷雾机性能及相关可靠性,展开了一系列实验研究与数值模拟来完成对其优化改进,从而提高各项指标。更多还原

【Abstract】 Aim at large-scale use of air-assisted sprayer on pesticide pest control technology,this paper summarized some advantages including large spraying swath,good uniformity,high efficiency and less conditionality etc.,and introduced one of the important performance indexes is spraying swath,the uniformity and sprayed droplets penetrability,distribution of subsidence rate are also important indexes.In order to reveal the performance and reliability of air-assisted orchard spryer,series of experiments and numerical simulation were launched to get the optimized improvement to improve the index.更多还原
