摘要
注射呋甲乳油 (用水 1∶1稀释 )至杨树体内 ,药剂可向上、向下传导 ,残留期超过一个月 .选用带NPD的气相色谱仪和 3 5%OV - 10 1+3 2 5%OV - 2 10柱 ,对呋甲乳油在树木内的残留量每隔 5d测定 1次 ,实验发现注药后 5～ 17d残留量较高 。
Carbofuran and Methamidophos Emulsifiable concentrate (diluted to a concentration 1∶1 with water) which was injectied into the trunk was carried up and down by the tree itself and remained there over a month. The residual dose of Carbofuran and Methamidophos in trunks was tested once every five days. The Gas Chromatography equipment has NPD and 3 5%OV-101+3 25%OV-210/Chromosorb WHP (80～100) mesh column. It was found that the more highly the residual dose remains, the more powerful poison it contains in 5-17 days after injecting.
