为了探讨被松材线虫病危害的濒死松树逆转的可能性 ,在松材线虫病发生区 ,当夏秋季松树表现出感病症状时 ,选择濒死松树 ,镜检松材线虫。确诊后 ,采用杀线虫剂和杀虫剂输液急救。试验表明 ,联合使用杀线虫剂和杀虫剂 ,可使感病的马尾松急救成活率达83 3% ;感病的黑松成活率达到 75 0 %。从急救成活可知 ,松树枯萎是松材线虫和松墨天牛双重作用结果。用药物清除树体内松材线虫和松墨天牛幼虫是濒死松树急救成活的基本机理。感染松材线虫病的濒死松树的死亡过程能被药物急救逆转。表 2参 1 6
In order to explore the possibility of the pine tree nematode endangering the pine trees reverse the possibility of pine wilt disease area, when the summer and autumn pine trees show symptoms, the selection of dying pine, microscopic pine wood nematode. After diagnosis, the use of nematicide and pesticide infusion emergency. Tests showed that the combined use of nematicides and insecticides, can make the survival rate of infected first-aid masson pine reached 83.3%; the survival rate of infected black pine reached 75%. From the emergency survival we can see that pine wilt is the dual role of pine wood nematode and Monochamus alternatus. The removal of pine wood nematodes and Monochamus alternatus larvae by drug removal is the basic mechanism for the survival of the first-aid pine trees. The process of dying pine trees infected with pine wilt disease can be reversed by first aid. Table 2 Participation 1 6
