塑料温室内的雾滴沉积分布研究

Distribution of Droplets Deposition in Plastic Greenhouses

为了开发设施农业病虫害防治的常温烟雾施药技术 ,在密闭温室内进行了常温烟雾喷雾雾滴沉积试验 ,对 4种机型、3种温室的试验结果作了分析比较 ,从而探讨了雾滴粒径与沉积密度的相关关系 ,喷射部件上设置的轴流风机对雾滴分布均匀性的提升作用 ,作物不同部位的雾滴沉积差异 ,并推导出施药时喷雾量的测算方法。

In order to develop the fog spraying technology used for pest control of establishment agriculture under normal temperature condition,the droplet deposition of fog spraying in sealed plastic greenhouses under the normal temperature was experimentally tested. Four sorts of sprayers and three types of plastic greenhouse have been analyzed and compared. Therefore,the correlativity between droplet diameter and density of deposition,the spraying part installed on the electrical axial flow fan,the lift function of droplet distribution uniformity,and droplet deposition difference on the different positions in crops have been analyzed.
