【摘要】 为了解澄迈地区香蕉黑星病发生特点，以澄迈县松涛水库灌区主栽香蕉品种‘宝岛蕉’为研究对象，采用定点定期方式，于2017—2020年间对该病害的田间消长动态进行了系统调查。结果表明，香蕉黑星病周年均可发生，季节流行曲线呈近“S”型，在1个生长季内的温暖多雨的9—11月及翌年高温多雨的5—8月，病情指数随香蕉生育期推移呈上升趋势，并分别于11月、翌年8月达峰值，其中8月峰值最大；其余月份温度、湿度相对较低，病害趋于平缓，呈波浪形。香蕉黑星病田间病情消长与湿度密切相关，温度次之，雨季尤其5—8月是香蕉黑星病的盛发期。此外，冬季及春夏之交持续阴雨或大雾也是病害加重的因素。更多还原

【Abstract】 To clarify the occurrence dynamics of freckle disease of banana in Chengmai area, the main banana cultivar ’Baodao banana’ in the Songtao Reservoir Irrigation Area of Chengmai County was selected as experiment object, and the dynamics of field growth and decline of the disease was systematically investigated in a fixed location and regular manner from 2017 to 2020. The results showed that freckle disease of banana occurred in the whole year with seasonal epidemic curve showing as nearly "S" shape. The disease index increased along the growth stage of banana from September to November when it was warm and rainy and from May to August of the next year when it was hot and rainy in a growing season, and reached the peak in November and August of the next year, with the highest peak appeared in August. In other months with relatively low temperature and humidity, the disease index in general tended to be gentle and wavelike. The occurrence dynamics of freckle disease of banana had close correlation with humidity, followed by temperature. The disease occurred seriously in rainy season, especially from May to August. In addition, continuous drizzle or heavy fog in winter and at the turn of spring and summer was the cause that aggravated the disease.更多还原
