在树干上面，悬挂吊瓶进而给树体治疗病虫害就是树木挂吊瓶法。这种方法是使用棉绳棉芯把吊瓶中的药水直接输入到树木的枝叶上，这样就能够达到治疗的目的。在防治各种蚜虫、介壳虫、红蜘蛛、吉丁虫、天牛等吸汁类害虫时，这种方法收效比较好。吊瓶可以采用如下方法：在树的主干部分钻1个小孔，并且保证孔口与树干呈现45°的夹角，孔的深度要达到髓心，然后把稀释好的药水注入到孔中，并将棉绳拉直。防治时，一定要注意不同的害虫使用不同浓度的药液，时间一般选在每年的4~9月份比较好。

最近几个月，听到“非典”这个词就使我不寒而栗，非典型肺炎的兴风作浪，使得原本美丽的春天笼罩了恐慌的阴影，雪白的口罩挡住了春季的芬芳，无论是在哪个角落，“非典”都是人们谈论的核心话题。
人们忙不迭地去购买消毒液、口罩等一些防非典物品。学校里也放了假，每天只有坐在书桌前近五个小时的枯燥学习。这二十多天曲指算算，我只出过三次门，你也许觉的好笑，可现在谁不是这样呢？在家里面，吃饭前妈妈总是亲自看我洗手，耳边不时传来妈妈自编的顺口溜：“饭前便后三洗手，细菌保准不入口。”之类的.话。电视、报纸里满眼的非典。在这紧张之余，人们更多的会关注战斗在非典一线的白衣战士们。原来我认为当医生非常轻松，只是给病人看病开处方，是个很令人羡慕的职业。可当我看到他们不顾个人安危，冒着时刻都有可能被感染的危险，不退缩，想为病人所想，急为病人所急，放弃家庭，放弃自我，把个人的生死置之度外时，我觉悟了，猛然由心底感到这个职业是如此神圣，如此伟大。我不仅仅只是敬佩百衣天使，更要立志做一名像他们那样具有延安精神的医生。
就是在这样非常特殊的时刻才能体现出一个人的品质，那些因救治非典病人而牺牲的人才是英雄，他们的死重与泰山！你看，与世长辞的白衣天使们正像天边那轮皓月，为还战斗在非典最前沿的医护工作者照亮前进的道路，为他们祈祷、祝福！
白衣天使，你们承载起光明与希望，守护着平安与健康，人们会永远感激你。其实抗击在非典一线战地里的人们和战地外那些普通人都拥有着一个共同的愿望，那就是：远离非典，幸福平安。让我们众志成城，共同期待明天美好的生活吧！

防治树木病虫害可以采取注药法，方法就是在树干上打孔，并往孔里注药，这样就能够使农药到达树体的各个部分，因此，不管害虫蚕食树体的哪个部位，都会中毒而亡。对树干注药要选择合适的时间，一般选择在树干萌芽到树干落叶前这段时间内，效果最佳的时间段应该是4~8月份之间。而有些时间段也不适宜用药，如树木落叶至萌动前这段时间。在选用农药的时候，应该选择内吸性比较强且对林木副作用较小的药物，具体选择哪一种，要因树而异。在药量使用上，也要根据树木的不同而定。一般胸径在15cm以上的大树，每株需要6~10mL的原液；胸径在10~14cm的中等树，每株需要4~6mL的原液；胸径在10cm以下的小树，每株需要2~4mL的原液。另外，药剂稀释程度也要考虑气温的变化；当气温比较低的时候，可以稀释到1~2倍，当气温比较高时，可以稀释到原液的3~6倍，这样就不会因药液浓度的太高而对林木产生不利影响。对林木进行打孔注药时，可以在距离地面15~50cm的位置使用直径为0.8~1cm木工钻或充电电钻进行打孔，且要呈45°的角度向下打孔，孔的深度为8~10cm，要保证孔的深度达到髓心为准。打孔时，也应注意孔洞在树干上呈螺旋上升的状态，数量大约为大树3~5个，中树为2~3个，小树为1个，而且要把孔中的锯末掏净，最后注入药液。在完成注药后，一定要用蜡、泥巴或者胶布把孔密封严实，这样注药孔就能够在大约2个月的时间愈合。此注药方法最为省工省药、不污染空气的，也不会伤害到天敌，能够达到良好的治疗效果。像天牛、木蠹蛾、吉丁虫等比较难以防除的害虫，使用这种方法更能够达到良好的效果。
