一、香蕉束顶病的发生情况 香蕉束顶病是一种严重威胁香蕉生产的病害。据报道,一九二○～一九二九年香蕉束顶病在澳洲流行,导致该洲整个香蕉种植业的崩溃。近年来,我国香蕉产区束顶病日趋严重。广东省香蕉主产地东莞县有14万亩的香蕉,受束顶病为害的已达9.8万亩,受害率70％;高洲县 8万亩的蕉园,束顶病发生的面积达到了3万亩,受害率37.5％。广西南宁郊区,一九七九年香蕉束顶病仅0.08％,一九八○年上升至5.3 ％,一九八一年扩大到14.4％,累计损失蕉林10万株,香蕉150万公斤以上。云南省已有大面积香蕉束顶病的感染区。福建省香蕉的主产地漳州一带,束顶病的发生也相当普遍。据上所述,香蕉束顶病已经严重地威胁着我国的香蕉生产。如果没有引起足够的重视,采取有效的预防措施,有可能使我国香蕉生产受到一场毁灭性的打击。
First, the occurrence of banana bunchy top Banana bunchy top disease is a serious threat to the production of banana disease. It was reported that banana bunchy disease was prevalent in Australia from 1920 to 1929, causing the collapse of the entire banana plantation in that continent. In recent years, the problem of bunchy tops in banana producing areas of our country is becoming more and more serious. Dongguan, the main producing area of banana in Guangdong province, has 14 million mu of bananas and 9.8 million mu of diseases affected by the overbaked disease. The damage rate is 70%. In Gaozhou County, 80000 mus of banana plantations, the area of bundle top disease has reached 30,000 Mu, the victimization rate of 37.5%. Nanning, Guangxi suburbs, banana bunchy top disease in 1979 only 0.08%, rose to 5.3% in 1980, expanded to 14.4% in 1981, the cumulative loss of 100,000 banana plantar, more than 1.5 million kilograms of bananas . Yunnan Province has a large area of banana bunchy top infection area. The main producing area of banana in Zhangzhou, Zhangzhou, the occurrence of bundle top disease is quite common. According to the above, banana bunchy top disease has seriously threatened the banana production in our country. If we do not pay enough attention to it, effective preventive measures may cause a devastating blow to banana production in our country.
