在我国柑桔生产上存在着三种重要的病毒和类似病毒的病害:柑桔黄龙病、柑桔衰退病和柑桔裂皮病。目前对这些病害主要是采取严格检疫与培育无病苗建立无病苗圃的方法来进行防治。培育无病苗的方法是采用湿热空气在49℃,50分钟和四环素处理,以1000ppm药液浸渍2小时,这种方法对防治黄龙病与衰退病虽然有效,但对裂皮病则无效。基于上述原因,我们尝试了一种既能消除黄龙病和衰退病病原,又能脱除裂皮病病原的方法。这就是茎尖微芽嫁接,它克服了热处理对裂皮病无效,四环素对衰退病无效,
There are three important virus and similar virus diseases in citrus production in our country: Citrus Huanglongbing, Citrus recession and Citrus sinensis split. At present, these diseases are mainly controlled by strictly quarantining and nurturing disease-free seedlings to establish disease-free nurseries for prevention and treatment. The method of cultivating disease-free seedlings is to use hot and humid air at 49 ℃, 50 minutes and tetracycline treatment, soaking in 1000ppm liquid for 2 hours. Although this method is effective in controlling Huanglongbing and degenerative diseases, it is ineffective against split-skin disease. Based on the above reasons, we have tried a method that can both eliminate the pathogen of the yellow dragon’s disease and the recession and remove the pathogen of the split disease. This is the shoot tip micro-grafting, which overcomes the heat treatment of split-skin disease is invalid, tetracycline is not effective for the recession,
