Pinus rigida plantation occupies about 15% of coniferous forest in Korea. Although P. rigida as one of the major planting species were widely planted in Korea during 1960-1970s, this species has been a target for regeneration due to reduced growth. The objective of this study was to know the proper fertilizer amount for Quercus serrata seedlings planted in harvested P. rigida plantation, Korea. Study site was located in Pocheon-si, Gyeonggi-do, Korea. Q. serrata bare-root seedlings (1+1) were planted with the density of 3,000 seedlings ha-1 in April, 2011 after harvesting P. rigida plantation in 2010. Compound fertilizer (N:P:K=3:4:1) was yearly fertilized three treatments (control : no fertilization, F1: 180kg ha-1 and F2: 360kg ha-1) in May from 2011 to 2013. In each treatment, three plots (200m2 per plot) were established in April, 2011 and 30 seedlings per plot were randomly selected for measuring the root collar diameter (mm) and seedling height (cm). Soil samples to the depth of 20 cm were randomly collected by three samples per plot before and after fertilization (April, 2011 and 2012), to measure soil chemical properties such as soil pH, total nitrogen (TN), available P., organic matter (OM), cation exchange capacity (C.E.C), etc. Significant differences ... 전체 초록 보기
