随着农村体制改革的开展,各地种植柑桔的积极性大为提高,因而柑桔苗木调动频繁,许多危险性害虫就会随着苗木传播开来,为了防止害虫传播最彻底有效的方法是使用毒气进行熏蒸处理,本文报导甲基溴熏蒸试验的效果。 试验方法 熏蒸处理是在一立方米体积密闭的木制熏蒸箱内进行。柑桔苗木去除全部土壤并剪去所有叶片(但保留叶柄以防药剂从伤口侵害枝干)。苗木紧密排列在箱内,根部用微带潮湿的焦泥灰保护,熏蒸结束后用水冲洗
With the reform of the rural system, the enthusiasm for growing citrus in various places has greatly increased. As a result, citrus seedlings have been mobilized frequently and many dangerous pests have spread along with seedlings. The most effective and effective way to prevent the spread of pests is to use poison gas For fumigation, this paper reports the effect of methyl bromide fumigation. Test methods Fumigation is carried out in a cubic volume enclosed wooden fumigation box. Citrus seedlings remove the entire soil and cut off all leaves (but leave the petiole to prevent the agent from invading the branches from the wound). Seedlings arranged closely in the box, root with a micro-humid coke dust protection, fumigation after the water rinse
