솜대 조림지와 확산지의 바이오매스, 임상, 토양의 양분 특성 = Nutrient Characteristics of Biomass, Forest Floor, and Soil between Plantation and Expansion Sites of Phyllostachys nigra var. henonis

국문 초록 (Abstract)

본 연구는 대나무 확산에 있어서 토양 성질이 미치는 영향을 조사하기 위해 매년 시비가 실시된 솜대 조림지와 미시비 확산지를 대상으로 바이오매스 부위별 양분 농도와 임상 및 토양 30 cm 깊이의 양분 특성을 비교하였다. 솜대 조림지의 잎, 가지, 줄기 내 질소와 인 농도는 확산지에 비해 유의적으로(P < 0.05) 높았으나, 임상의 양분 농도는 조림지와 확산지 사이에 유의적인 차이가 없었다. 토양 0∼30 cm 깊이의 평균 유기탄소는 조림지가 30.80 mg g^-1으로 확산지 15.64 mg g^-1에 비해 유의적으로 높았다. 평균 전질소 농도의 경우 조림지 2.47 mg g^-1, 확산지 1.24 mg g^-1, 인은 조림지 10.27mg kg^-1, 확산지 5.61 mg kg^-1, 포타슘은 조림지 0.27 cmolc kg^-1, 확산지 0.16 cmolc kg^-1로 조림지가 확산지에 비해 유의적으로 높았다. 본 연구 결과에 따르면 토양 양분 상태는 솜대의 인접 산림지역으로 확산에 큰 영향을 끼치지 않는 것으로 나타났다.

In this study, the relationships between bamboo expansion and the nutrient characteristics of bamboo biomass, the forest floor, and mineral soil (at 30-cm depth) were determined in unfertilized expansion sites and fertilized plantations of Phyllostachys nigra var. henonis in Jinju, Gyeongsangnam-do. Nitrogen and phosphorus concentrations in bamboo components (culm, branches, and foliage) were significantly higher in the plantation site than those in the expansion site (P < 0.05). However, the nutrient concentration of the forest floor did not differ significantly between the plantation and expansion sites. Mean organic carbon concentration at 0-30-cm soil depth was significantly higher in the plantation site (30.80 g kg^-1) than that in the expansion site (15.64 g kg^-1). In addition, total nitrogen, phosphorus, and exchangeable K⁺ at 0-30-cm soil depth were significantly higher in the plantation site than those in the expansion site. These results indicate that bamboo can spread to areas with low-nutrient concentrations in adjacent forests.
