在1959年第一期“林业科学”杂志里刊登了劳可遒同志的“关于鱼鳞松主伐年龄的意见”一文。作者在文章中建议提高东北鱼鳞松主伐年龄。其主要理由大概有以下几点:一、鱼鳞松林的各种主要材种平均生长量达到最大的时期不是第Ⅴ龄级而是第Ⅵ龄级。二、平均高和平均胸径在第Ⅴ龄级时尺寸较小。三、采伐后能继续不断地保持有可能利用的森林。 In the first issue of 1959, “Forestry Science” magazine published Comrade Lau Cola “on the scale of the main views of scales” article. In the article, the author proposes to raise the age of cut outerschia sylvestris. The main reason there are about the following points: First, the scale of pine timber forest all kinds of main species to achieve the maximum average growth period is not the first Ⅴ age class but the first Ⅵ age class. Second, the average height and average diameter at the age of the first grade class size smaller. Third, after logging can continue to keep the forest may be used.
