手动喷雾器常量喷雾,是目前主要的施药方法,优点是覆盖好,机具价廉,便于小面积作业,但工效太低,难以达到及时防治。而现推广的机动弥雾机低容量和超低容量喷雾技术,工效约为前者的30多倍,但需专门机动机具和专用油剂(超低容量),易受地形等条件的限制。我们于1981年对手动喷雾器作了改革,实行低容量喷雾,取得较好效果,现报告如后。一、试验方法 (一)试验地设在宁陕县农场稻田,品
Manual spray constant spray, is the main method of application, the advantage of good coverage, cheap machines, easy to small area operations, but the work efficiency is too low, it is difficult to achieve timely control. And now the promotion of low capacity and low volume spray motor fog machine technology, the work efficiency of about 30 times the former, but the need for special motor equipment and special oil (ultra-low capacity), vulnerable to topography and other conditions. We made a change to the manual sprayer in 1981, implementing a low-volume spray and achieving good results. The report is as follows. First, the test method (a) test ground located in Ningshan County farm rice fields, products
