次生林冠下营造红松，应选择了阴坡、半阴坡的中下腹及缓坡、上层深厚、排水良好的地段，实行顶浆造林。栽植密度：郁闷度在 ０．４～０．６时， ２ ０００～３ ３００株／ｈｍ２；郁闭度０．３以下时，３３００～４４００株／ｈｍ２；０．６以上为１５００／ｈｍ２左右。幼林抚育要进行５ａ，造林１０ａ进行透光抚育代， ２０ ａ左右伐除上层阔叶树时，保留具有培育前途的阔叶幼树，从而形成高产稳产的阔叶红松林。
Under the canopy to create Korean pine, should choose the shady slope, half-shady in the lower abdomen and gentle slope, the upper deep, well-drained areas, the implementation of achivement afforestation. Planting density: Depressed degree of 0.4 to 0.6, 000 to 3 300 / hm2; canopy density of 0.3 below, 3300 ~ 4400 / hm2; 0.6 more than about 1500 / hm2. Nursery tending should be carried out for 5 years and afforestation for 10 years. When the upper broadleaf tree is cut at around 20 years, young broad-leaved trees with nurturing future are reserved to form the broad-leaved Korean pine forest with high and stable yield.
