| 摘 要： | 调查了不同甘蔗品种、施肥水平、蔗田地势及气候条件下，甘蔗黄点病的发生情况。结果表明，甘蔗品种间对黄点病的抗（感）病性存在显著差异，Ｒｏｃ部分品种较感病，其中Ｒｃｏ１０最感病；７９／１７７、７１／２１０、９３／２９３及果蔗等品种（系）较抗病．氮肥可加重黄点病发生，钾肥可减轻黄点病发生。蔗田地势低洼、易积水，病害发生严重．温度适宜、天气长期阴雨、田间湿度大，有利于黄点病发生；在此条件下，若遇台风袭击，黄点病可能大流行．

| Abstract: | The developmental laws of sugarcane yellow spot disease were investigated under theconditions of the different sugarcane varieties, quantities of fertilizer N and K, surface relief ofcane field and climatic elements. The results showed that the susceptibilities among the sugarcanevarieties had significant difference. The susceptibilities of the varieties of ROC were higher thanthat of the varieties of 79/177,71/210,93/293 and fruit cane. Fertilizer N could help the diseasedevelopment, while the fertilizer K inhibite that. The disease developed more seriously in thelow--land than that in the highland. The high humidity, long time raining would deteriorate thedisease. Once typhoon occurs the disease would become epidemic. |
