| Abstract: | Growth investigation of Populus ussuriensis and P. koreana and Pinus. koraiensis artificial forest less than 30 year old showed that the breast diameter reached 7.5cm at 27 year old. The directed cultivation, second afforestation on the clear cutting land, short cutting rotation improved the growth significantly. The optimum density was 3 300 stocks/hm2 |
