低容量喷雾是近年来应用较广的一种喷施农药的方法,和传统的大客量、大雾滴喷雾相比,它具有工效高、药效好的优点。由于低容量喷雾方法受环境因素(如风力、风向等)影响较大,使用时应注意以下几点: (1)喷头调整用手动喷雾器(工农16型或552-丙型)时,喷嘴应换上0.7～1.0mm的喷头,要拿出喷头涡流室的垫圈。 (2)施药量一般用手动喷雾器时,喷药量为150kg/hm~2左右,用机动喷雾器时,喷药量为30kg/hm~2左右。 (3)药水要求农药应选用
Low-volume spray is widely applied in recent years, a method of spraying pesticides, and the traditional mass, mist spray compared to it with high efficiency, good efficacy advantages. As low-volume spray method by the environmental factors (such as wind, wind, etc.) a greater impact, the use of the following points should be noted: (1) nozzle adjustment manual sprayer (workers and peasants 16 or 552- C), the nozzle should be replaced 0.7 ~ 1.0mm on the nozzle, to take out the nozzle vortex chamber gasket. (2) the amount of pesticide spray is generally used when the hand spray rate of 150kg / hm ~ 2 or so, with a mobile sprayer, the spray amount of 30kg / hm ~ 2 or so. (3) syrup requirements of pesticides should be used
