近年来,我省芦笋种植面积迅速扩大,如连云港市1978年引种试种,现已发展到1.2万亩。但由于茎枯病危害严重,有的株发病率达50～60％,南京地区二年生笋芽病株率达80％以上,造成枯死、缺株,甚至全田毁灭,直接影响经济收入。据文献记载,此病在我国黑龙江、河北、河南、山东、江苏、安徽、浙江、福建、台湾等省及日本、朝鲜等国家均有发生。我们于1986～1987年,对芦笋茎枯病的为害症状、病原、感病期及防治方法等进行了初步研究,现将试验结果整理如下。
In recent years, the planting area of asparagus in our province has rapidly expanded. For example, introduction of planting seeds in 1978 in Lianyungang has now developed to 12,000 mu. However, due to the severe damage of stem blight, the incidence of some strains is up to 50-60%. The rate of biennial shoot sprouting in Nanjing is more than 80%, resulting in the death, absence of plants and even the whole field destruction, which directly affects the economic income. According to the literature, the disease occurred in China’s Heilongjiang, Hebei, Henan, Shandong, Jiangsu, Anhui, Zhejiang, Fujian and Taiwan provinces as well as Japan and North Korea. We from 1986 to 1987, the damage symptoms of asparagus stem blight, the pathogen, the period of susceptibility and prevention methods such as a preliminary study, the test results are summarized below.
