본 연구는 소나무재선충병 피해지의 식생복원을 위해 조림된 편백을 대상으로 토양개량제의 처리 효과를 조사하기 위한 목적으로 수행하였다. 2007년 소나무재선충병 피해지에 모두베기 후 조림된 8년생 편백을 대상으로 2013년부터 2016년까지 4년 동안 목탄과 톱밥을 두 수준의 복합비료(N6:P4:K1, N3:P4:K1)에 혼합 처리한 토양개량제 처리구와 무시비구(대조구)를 대상으로 임목 생장, 토양 및 잎 양분 특성을 조사하였다. 조사기간동안 흉고직경 또는 수고 생장량과 측정시기에 대한 선형회귀식의 회귀계수(slope)는 유의적인 차이가 없었으나, Biomass 증가량은 토양개량제처리구와 대조구 사이의 회귀계수에 유의적인 차이가 있었다. 그러나 복합비료의 시비 수준의 회귀계수는 유의적인 차이가 없었다. 토양 EC를제외한 토양 호흡, 토양온도, 토양수분 함량, 토양 pH는 토양개량제 처리구와 대조구 및 시비 수준 사이에 유의적인 차이가 없었다. 토양의 화학적특성 중 유기탄소와 전질소 농도는 토양개량제 처리구가 대조구에 비해 유의적으로 낮은 값을 보였으나, 유효 인, 교환성 칼슘 및 마그네슘은토양개량제 처리구가 대조구에 비해 유의적으로 크게 나타났다. 잎의 질소 및 인 농도는 토양개량제 처리구가 대조구에 비해 증가하였으나, 칼륨과마그네슘 농도는 처리 간 차이가 없었다. 본 연구 결과에 따르면 소나무재선충병 피해지 식생복원을 위한 편백 조림지에 토양개량제 처리는 양분유효도의 향상 및 조림목의 바이오매스 증가에 기여할 수 있는 것으로 나타났다.
Abstract
This study was carried out to evaluate the response of soil amendment applications on the tree growth, the nutrient status of soiland foliage of a Japanese cypress (Chamaecyparis obtusa Endlicher) plantation established following clearcutting in a pine wilt disease(PWD)-disturbed forest. The tree growth, soil nutrients, and foliage nutrients were monitored for four years (from March 2013 to October2016) with soil amendment treatments [compound fertilizer (N6:P4:K1) with woodchar and sawdust, compound fertilizer (N3:P4:K1) withwoodchar and sawdust, and a non-treated control treatment] in an 8-year-old Japanese cypress plantation. The regression coefficientsof the increments of diameter at breast height (DBH) and height were not significantly different between the soil amendment plots andthe control plots, whereas the coefficients of biomass increments were affected by fertilizer applications suggesting a significant soilamendment treatment effects. The regression coefficients were not significantly different between the two soil amendment treatment plots. Soil respiration, soil temperature, soil water contents, and soil pH were not affected by soil amendment treatments, except for highsoil EC in soil amendment plots. Organic carbon and total nitrogen concentrations were lower in the soil amendment plots than inthe control plots, where available phosphorus, exchangeable calcium and magnesium of soils were higher in the soil amendment plots than in the control plots. Nitrogen and phosphorus concentrations in foliage were higher in the soil amendment plots than in the controlplots, but organic carbon concentration was lower in the soil amendment plots than in the control plots. The potassium and magnesiumconcentrations in foliage were not affected by soil amendment treatments. The results suggest that soil amendment treatments couldbe used to enhance the tree biomass and soil nutrient availability in PWD-disturbed forests
