溃疡病是一种摧毁性的病害,又是主要的检疫对象,在柑桔育苗中至为普遍,特别是甜橙最易感染,但并不是不可消灭的。我场在1954年冬建立柑桔苗圃,至今已有四年多,其中90%以上都是育甜橙苗,共出圃苗木30万株,均无病害。能获得这个成绩完圣是由于在党的正确领导下,贯彻一系列的措施,主要经验有下列几个方面:一、采种和种籽处理:作为采种用的种果最好是到无病区去采集,但我区溃疡病很普遍,如南宁市郊的明秀,秀廂乡的甜橙,邕宁县的那陈橙,几乎100%的母树都染病,因此必须在有病的母树上选无病的果子,剥出种子后经过0.5—0.6硫酸铜液浸5分钟消毒,
Canker disease is a devastating disease and the main quarantine object, which is common in citrus nurseries. In particular, orange is the most susceptible but not indispensable. My field in the winter of 1954 to establish citrus nursery, has been more than four years, of which more than 90% are sweet orange seedlings, a total of 300,000 nursery nursery stock, no disease. The accomplishment of this accomplishment is due to the implementation of a series of measures under the correct leadership of the party. The main experiences are as follows: I. Seed collection and seed treatment: It is best to use seedless fruits as the seed for seed collection However, ulcer disease in our area is very common. For example, there are Mingxiu in Nanning, the orange in Xiuxiang, the orange in Suining, and almost 100% of the mother trees are infected. Therefore, it is necessary to choose a disease-free mother tree Of the fruit, stripped of seeds after 0.5-0.6 copper sulfate immersion for 5 minutes disinfection,
