对于数量多的害虫和害螨若采用放大后直接记数叶片上各发育阶段的数量的方法,很容易使人疲劳,从而导致很大的记数误差。本文介绍了一种解决这个问题的采虫(螨)机。经验证,达到了令人满意的精度。材料和方法洗叶机:这种洗叶机(图见原文)主要由一个洗槽、一根冲洗管道,一组流速控制阀,一根流出管道,一溶液盆和一个水泵构成。操作:先开泵、再将叶片放入盛有洗液的水槽内,调整各部件,10分钟后将叶片取出。
For a large number of pests and pests mites if amplified directly count the number of developmental stages of leaves, it is easy to make people tired, resulting in a large number of errors. This article describes a mining insects (mites) machine to solve this problem. Proven to achieve a satisfactory accuracy. Material and Method Leafwashing Machine: This leafwashing machine mainly consists of a sink, a flushing pipe, a set of flow control valves, an outflow pipe, a solution bowl and a water pump. Operation: First open the pump, then the leaves into the tank filled with lotion, adjust the components, 10 minutes after the leaves removed.
