密闭空间冷烟雾滴沉积分布特性研究

Airtight Spatial Cold Smoke Droplet Deposition Distributed Characteristic Research

对常温烟雾机进行了密闭棚室喷雾试验,研究常温烟雾施药技术在南方中档塑料棚室内的喷雾适应性、雾滴沉降分布规律、雾滴沉积密度及试验参数设置合理性。结果表明:雾滴沉积均匀性较好,变异系数平均为0.28;雾滴沉积密度很高,平均在31.44粒/mm2;试验参数设置基本合理。采用常温烟雾施药技术将提升设施农业病虫害防治水平。

Carried on the airtight awning room spraying experiment to the cold aerosol sprayer, the research cold aerosol has executed the medicine technology in the south middle-grade plastic awning room spraying compatibility, the droplet subsidence distribution rule, the droplet deposition density and the experimental parameter establishment rationality. The result indicated that, the droplet deposition uniformity is good, the coefficient of variation is equally 0.28; the droplet deposition density is very high, average in 31,44 grain of /mm2; Experimental parameter establishment basic reasonable. Will use the cold aerosol to execute the medicine technology to promote the facility agriculture plant disease to prevent and control the level.
