摘要
<正>通过对福建、广东、广西和江西省(区)14个林场湿地松和火炬松松针褐斑病(Lecanosticta acicola)危害程度及发病特点调查,把松针褐斑病的区域归纳为3种类型:主要流行区、偶然流行区和无害区。根据各林场林分感病程度和所在县近十年气候因子建立直线回归方程,并根据回归方程对中国南方主要地区褐斑病流行程度进行了预测。
Abstract
3 types of brown-spot needle blight (Lecanosticta acicola) in epidemic zones were divided on the basis of investigation into disease damage and disease characteristics of 14 forest farms in Fujian, Guangdong, Guangxi and Jiangxi Provinces (or autonomous regions). They are primary epidemic zones, accidental epidemic zones and non-damage zones. Regression equation was built on the standing damage of 14-16 years slash pine and climatic factors of 14 forest farms. The epidemic degree of brown-spot needle blight in southern China was forecasted according to the regression equation.
