野燕麦是阿勒泰地区广大麦田的恶性杂草之一.近年来,我们用燕麦畏(美国孟山都公司产)防除野燕麦取得了良好效果.唯目前生产上使用的泰山—18型或手持超低量喷雾器,用于大面积喷施燕麦畏,劳动强度大,效率低,易误农时,喷药后又不能及时耙地,使药液挥发损失而降低防效.我们经过反复研究,试制了3W—3喷药机械,1984年10月下旬进行小面积喷施试验,至1985年7月30日调查,防除野燕麦效果达83%以上.该机喷洒面积已达3,000余亩.该机结构简单,每台制作费仅250元;操作 Wild oats is one of the weeds in the vast wheat fields in the Altay region. In recent years, we have achieved good results using oatmeal (Monsanto, U.S.A.) to control wild oats, except for the Taishan-18 or hand-held ultra-low-volume Sprayer, for spraying large areas of oatmeal, labor-intensive, low efficiency, easy to agricultural, spraying and can not be harrowed in time, so that liquid volatile loss and reduce the effect of prevention .We after repeated research, trial production of 3W- 3 spraying machine, small area spray test was carried out in late October, 1984. Until the investigation on July 30, 1985, the effect of controlling wild oats reached more than 83% .The spraying area of ​​this machine has reached 3,000 mu.The structure of the machine is simple, Each production costs only 250 yuan; operation
