目前很需要一种能将药液喷洒成雾滴大小均匀、尺寸可以调节、喷药量为0.5～10升/公顷,能进行超低量喷雾的机引喷雾机。在试验过程中,首先研制了实验室用和小地块用的喷雾机和降雨机,这些机具的喷药量为0.5升/公顷或0.5升/公顷以上,能将药液分散成大小相同、尺寸由50 At present, there is a great need for a machine-sprayer capable of spraying a chemical solution into a uniform spray-drop size that can be adjusted in size and sprayed at an amount of 0.5 to 10 liters per hectare for ultra-low-volume spraying. In the course of the experiment, we first developed laboratory and small plots of sprayers and rainfall machines with a spray volume of 0.5 liters / hectare or 0.5 liters / hectare to disperse the liquid into the same size, Size from 50
