红松是长白山林区主要用材树种之一,同时也是经济树种,生产的木材个大质优,林付产品多种多样(如松籽、明子、松针等),因而深受人们的喜欢。建国以来,我区各地营造了大量的红松人工纯林,生长的繁茂、茁状、非常良好。但是近几年来,却发现了大量的病害,使红松的生长受到了严重的影响,并且蔓延的快,大有危及全林之势,其中尤以“红松疱锈病”为最甚。因此,我们在一九七九和一九八○年,对红松疱锈病进行了初步的调查,现将调查的结果报告如下: Korean pine is one of the main tree species in Changbai Mountain.

They are very good. However, in recent years, however, a large number of diseases have been found, which has seriously affected the growth of Korean pine and has spread rapidly and greatly threatened the whole forest. Particularly, “Korean pine blister rust” is the most serious. As a result, we conducted a preliminary survey of red rust blisters in 1979 and 1980 and the results of the survey are reported as follows:
