试验药剂磷化铝由山东济宁化工厂生产,每片重3.3g,含磷化铝56.6%～58.5%;毒扦由西北林学院昆虫研究室提供,将磷化锌与草酸混合固定于竹签顶端蜡封制成。试验分别以磷化铝片剂的1/4、1/8、1/12、1/16和1/20进行防治对比分析,以确定磷化铝的最佳用量。试验方法,在标准地内随机选取标准木,找出天牛蛀道,将磷化铝片剂放入虫道,用泥封口;毒扦防治是将毒扦插入蛀道塞紧。施药10天后检查防治效果,进行防效分析。
The test agent aluminum phosphide is produced by Shandong Jining Chemical Plant, each weighing 3.3g and containing 56.6% -58.5% of aluminum phosphide. Poison sticks are provided by the Insect Research Laboratory of Northwest Forestry College, and the zinc phosphide and oxalic acid are mixed and fixed on bamboo sticks Top wax seal made. The experiments were respectively compared with 1/4, 1/8, 1/12, 1/16, 1/1/20 of aluminum phosphide tablets to determine the optimal dosage of aluminum phosphide. Test methods, in the standard random selection of standard wood, to find the cerambyans tunnel, the aluminum phosphide tablets into the worm, mud seal; poison stick prevention is to poison into the tunnel tight. Ten days after the application of pesticides to check the effectiveness of prevention and control.
