摘要

<正>1986~1989年在江西省奉新县湿地松人工幼林中的观察表明,松针褐斑病于每年6月中旬至7月中旬发展较快,9月中旬至10月下旬病情也有一定增长。植苗造林后3~4年内病株率和感病指数逐步上升,第5年后病株逐渐恢复健康。在幼林中病害自发病中心迅速扩散,但不造成明显损失。

Abstract

The development of brown spot needle blight of pines was investigated in young slash pine plantations in Fcngxin County, Jiangxi province in 1986-1989. The results showed that the disease index increased more rcpcadly in the middle of June to the middle July, and the next middle in September to October every year. The incidence increased gradually within 3-4 years after planting and decreased since the fifth year. The disease spread rcpcadly from the infection focus but with less damage.
