中央公园园林植物白蚁防治探析

Investigation and Control of Termite in Garden Plants of Songjiang Central Park

调查了上海松江中央公园内园林植物受白蚁危害情况。选取受白蚁危害的71株树木、2个对照组为试验材料。71株树木采用毒土结合粉剂处理法;对照组1采用蚁克粉处理法;对照组2不做任何处理,处理50d后,观察分析试验结果。发现毒土结合粉剂处理法灭治率达93.0%,且效果稳定,没有反复性;蚁克粉处理法灭治率为33.3%,效果不稳定,存在反复性,灭治后需要反复更换、添加药剂,才能保证树木免遭白蚁的再次危害;未做处理的对照组2仍然存在白蚁。对比不同治理方法,毒土结合粉剂处理法优势明显,且对人体、环境无害,可逐步取代毒性较强的传统药剂和方法。

This paper investigated the termite hazard of garden plants in Shanghai Songjiang Central Park with 71 trees destroyed by termites and two control groups as study case.These 71 trees were used toxic soil treatment combining with powder therapy,control group 1 was used ant gram powder treatment,meanwhile without any treatment on control group 2.After 50 days＇ treatment,therapeutic effect was as follows：The elimination rate of toxic soil treatment combining with powder therapy reached 93.0% with stabilizing effect.Ant gram powder treatment reached 33.3% with instable effect and repeatability,and the trees still require repeated replacement and needed to add medicaments after eradication to prevent the trees from termite damage again.Control group 2 still suffered from termite hazard.Comparing the different treatment plan,toxic soil treatment combining with powder therapy had obvious advantages,harmless to the human body and environment,and can gradually replaced traditional strong toxic medicaments and methods.
