Description

树干截留法防治松毛虫技术
本发明涉及一种树林管理中,松毛虫的防治技术;具体地说是用于防治松毛虫的一种树干截留法防治技术。
松毛虫是松树等树木的毁灭性的害虫,大面积发生时有“不冒烟的火灾”之称。当前防治松毛虫的办法主要有以下几种:1、叶面化学喷雾防治,即向树叶喷洒药物。其工作量大,污染环境;喷洒后如遇阴雨天,其效果极差;且在杀害松毛虫的同时,也杀害了松毛虫的天敌,破坏了生态平衡。2、树基部打孔注药,通过树干吸收药物,防治食叶幼虫。其工作量大,不便于操作,药效缓慢,且对5龄以上的幼虫效果明显减弱。3、幼虫下树越冬或上树取食时,树干系毒绳(环)防治。其季节性强,只能在幼虫上树或下树时有效,否则失去效果;雾、雨天,毒绳(环)上药物易失效,影响防治效果;且大面积防治时难以掌握时机。4、其它防治办法:如烟雾剂熏杀,灯光诱杀,人工摘虫等这些方法效果更不理想。
本发明的目的就是提供一种操作简单,无毒、不污染环境,不受季节和气候限制,防治效果显著,有效期长的树干截留法防治松毛虫技术。
为达上述目的,本发明采取的技术方案是,在树干一定的高度上,设置一个具有一定宽度的、表面光滑的防护带。这样,松毛虫的幼虫在上树食叶时,爬到防护环上,因防护环表面光滑,便滑落下去,不能再上树食叶,不久因不能食叶,幼虫便自然死亡,达到防治松毛虫的目的。
松毛虫幼虫越冬多数在树干高1.5米以下的皮缝内或地下越冬。本发明是在树干高1.8米及以上处,设置一个宽度不少于5厘米的、表面光滑的防护带。松毛虫幼虫开春后在上树食叶时,爬至防护带,因防护带表面光滑,而滑落下去,这样松毛虫幼虫因食不到松树叶、而自然死去,达到了防治松毛虫的目的。防护带可用表面光滑的塑料带(如透明胶带,表面光滑的塑料胶带等)紧紧缠绕在树干上制成。
本发明的防护带也可采用表面光滑的塑料带缠绕在树干上,其上沿紧紧绑在树干上,这样当松毛虫幼虫爬至防护带表面时,便会滑落下去,如有少数爬进防护带内,因上沿紧紧绑住,仍不能上树食叶,也同样达到防治目的。
下面为本发明的一个实施例。
某林场在松毛虫幼虫下树越冬后至次年开春前,对万亩松树设置了防护带,用宽5厘米的透明胶带和表面光滑的塑料胶带,在树干高1.8米以上处,树干表面较平整(如有凸起的树节等可进行修整),紧紧缠绕一周,防护带表面不要起皱,历时一年证明,有效地防止了松毛虫害,有效率达98%以上;同时节约资金50万元以上。
由于本发明操作非常简单,防护带表面不需药物,不污染环境,不受季节、天气的影响,且使用时间长,因此,本发明具有操作简便,无毒、无污染、不破坏生态环境,不受季节、天气影响,有效期长,防治效果显著,投资少等特点,为林区提供了一种简便实用、投资少,能有效防治松毛虫害的树干截留法技术。
