广西特产罗汉果(Momordica grosvenoriSwingle)具有多种药用功效,近年来已在广西各地及邻近省份大力引种栽培。严重为害罗汉果生产的根结线虫病[Meloidogyne javanica(Trenb 1885)Chitwood 1887]也随着带病种薯到处传播,致使此病在各罗汉果产区普遍发生。为了预防罗汉果根结线虫病的继续传播和蔓延,对带病的种薯必须进行处理。为此,我们从1981年起,探索解决种薯带病的途径和方法。试验表明,利用热水定温、定时浸渍种薯的方法,能够杀死种薯上携带的病原线虫,而且不影响种薯的萌芽、生长、开花结果。现把试验结果报告如下:
Guangxi specialty Mangosteen (Momordica grosvenoriSwingle) has a variety of medicinal properties, in recent years has been vigorously around Guangxi and neighboring provinces introduced cultivation. Meloidogyne javanica (Trenb 1885) Chitwood 1887, which is a serious culprit, is also widespread in diseased mangosteen areas with the spread of diseased tubers. In order to prevent the continued dissemination and spread of Luo Han fruit root knot nematode disease, the diseased seed must be dealt with. To this end, we have explored ways and means to solve the problem of potato disease from 1981 onwards. Experiments show that the use of hot water temperature, the method of timely immersion seedlings can kill pathogenic nematodes carried on the seed, and does not affect the seed germination, growth, flowering results. The test results are reported as follows:
