On the Pesticide Application Methods used Fogging Machine by Ultra Short Waves System for Cultivation under Structure

为了提高设施栽培植物的喷雾沉积效率，采用超短波喷雾机进行喷雾。传统的喷雾机广泛应用于建筑物下耕作，但存在一定的缺陷。特别是在常规喷雾机的情况下，据说植物的下部和反面的叶片喷雾沉积很少。采用常规雾化机和超短波雾化机，在小型乙烯基室的植物模型上进行了雾化实验。通过雾化能力的测定，认为超短波雾化器的雾化效率不受各药剂的表面张力和粘度的影响。与常规喷雾机相比，植株下部叶和反面叶的沉积密度分别提高了40~55个百分点。在超短波喷雾机喷雾体积为4.6万L/10a的情况下，结构下栽培植株叶片的沉积密度最高。

In order to improve the spray deposition efficiency on plants in cultivation under structure, fogging machine by ultra short waves system was used. Conventional fogging machine which is widly used for cultivation under structure, but it has some faults. Especially, it is said that the lower and the reverse leaves of plants are little spray deposition in the case of conventional fogging machine. The conventional and the ultra short waves fogging machine were used to examine their spray deposition on plant models in small vinyl house. The results were as follows.Judging from the measurements of fogging ability, it is considered that the fogging efficiency of ultra short waves fogging machine is not affected by the surface tension and viscosity of each dilluted chemicals. Deposition densities of the lower and the reverse leaves of plants were increased in a percent from 40 to 55 than those of conventional fogging machine respectively. In the case of spray volume of 4.6 L/10a by ultra short waves fogging machine, the highest deposition densities of plant leaves in cultivation under structure were shown.
