조림 묘령에 따른 고로쇠나무 조림목의 생장 및 수관경쟁 특성

윤준혁,진언주 경상대학교 농업생명과학연구원 2021 농업생명과학연구 Vol.55 No.2

본 연구는 고로쇠나무 조림 시 묘령이 수목의 생장과 수관경쟁에 미치는 영향을 이해하고자 수행되었다. 3년생 조림지에서 1년생 조림지 보다 수고, 흉고직경, 수관면적은 유의적으로 높았으며, H/D율은 3년생 조림지에서 낮게 나타나 수고생장 대비 직경생장이 유도되는 것으로 나타났다. 조림지별 수목의 총연륜생장은 조림 묘령에 따라 유의한 차이를 나타내 직경생장에 영향을 준 것으로 해석된다. 조림지 임분의 수관경쟁 정도를 평가할 수 있는 수관경쟁지수(CCF)와 수관경쟁률(CCR) 또한 수목의 수고, 흉고직경, 연륜생장 특성 등과 동일한 경향을 나타내었다. 본 연구결과를 종합적으로 고려할 때, 고로쇠나무 생장의 측면에서 3년생 묘목 식재의 장점이 기대되며, 이러한 연구결과는 조림 후 수액채취 시기 및 채취량 등 경영의사결정에 활용 될 수 있을 것으로 기대된다. This s tudy was conducted to understand the e ffect o f the seedling ag e of Acer pictum subsp. mono on the growth and crown competition in plantation. The tree height, diameter at breast height and crown area were significantly higher in the 3-year-old plantation than in the 1-year-old plantation. The H/D ratio decreased as the planting seedling age increased, and it was found that diameter growth was induced compared to height growth. It was interpreted that the total annual growth of trees by plantation sites showed a significant difference according to the planting seedling age, which influenced the diameter growth. The Crown Competition Index (CCF) and the Crown Competition Rate (CCR), which can evaluate the degree of crown competition in the plantation stand, also showed the same tendency such as tree height, diameter at breast height, and annual ring growth. In conclusion, planting of 3-year-old seedling is expected to b e advantag eous in terms of the g rowth of A. pictum subsp. mono, and the results of this study are expected to be used in management decisions such as the timing and amount of sap collection in plantation.

Semi-industrial zone is the area where manufacturing, residential, commercial zones are mixed. Despite of their potentials in that proximity to city and convenient transportation infrastructure, a lot of semi-industrial zones in Korea have converted to other uses due to many issues such as change of industry, increasing land price, real estate speculations. Recently, local government is trying to solve their existing issues and develop them through a restoration of publicness. Now publicness is thought of as a key factor of regeneration in semi-industrial areas. In this regard, this study aims to examine the way of restoring publicness revealed in Brooklyn Navy Yard mainly focus on their urban contexts and architectural ways. Brooklyn Navy Yard, an exemplary case, is an industrial complex that has grown economically, socially and culturally through emphasizing publicness and it is evaluated as an advanced example of public industrial complex. Through the analysis of Navy Yard, this study was trying to emphasize the importance of publicness in the regeneration of semi-industrial areas and to provide implications for the Seoul Government's solutions, which are still in the conceptual stage. To analyze the publicness of the study subjects, framework and elements were derived by examining related theories and prior researches. Depending on this frame, the results of the publicness of the Navy Yard were as follows. First of all, the 'Publicness as an officiality' was identified at the characteristic of the site and Navy Yard development corporation. Second, the 'Publicness as a public interest' of the Navy Yard Development Corporation was identified in various ways of its operation methods. Finally, the 'Publicness as an accessibility' was identified in the opening of urban and architectural spaces in Navy Yard. These publicness were analyzed with seven Navy Yard's success factors. Thus, it can be interpreted that the publicness of the semi-industrial areas can contribute significantly to their success. The publicness restoring methods of Navy Yard could be used as a basic data in semi-industrial areas in the future in Korea. However they are limited to be applied directly, so extensive and in-depth research in terms of their applicability should be conducted.

컨테이너 재배에서 점적 관수처리가 왕벚나무 4, 8년생 묘목의 품질에 미치는 영향

윤준혁,진언주,배은지 한국산림과학회 2022 한국산림과학회지 Vol.111 No.3

This study was conducted to optimize the amount of drip irrigation for Prunus×yedoensis Matsum., one of the major medium-sized landscaping trees used mainly for streetscapes and as ornamentals. The experiment was conducted in a container nursery, where we assessed the growth and physiological characteristics of 4- and 8-year-old seedlings watered at different rates (x) by a drip irrigation system. The relative growth rates (based on height and root collar diameter (RCD) measurements) were highest at 288 and 416 L/year/tree for the 4- and 8-year-old containerized seedlings, respectively. These age and treatment combinations also produced significantly different dry weight and seedling quality index values, indicating good growth. The two age groups had significantly different total root lengths, root diameters, and root volumes under these respective irrigation treatments. In addition, the 4-year-old containerized seedlings irrigated at 288 L/year/tree and the 8-year-old containerized seedlings irrigated at 416 L/year/tree had the highest activations in their chlorophyll contents. Overall, the results (differences in irrigation amounts affect the seedlings morphological relative growth, biomass growth, seedling quality, and physiological reaction) indicate that the optimal irrigation amounts for container-grown Prunus×yedoensis are 288 L/year/tree for 4-year-old (RCD class, 3cm) and 416 L/year/tree for 8-year-old (RCD class, 7 cm) containerized seedlings. 본 연구는 우리나라의 가로경관 및 관상 목적으로 활용되는 주요 중형 조경수인 왕벚나무를 대상으로 컨테이너 재 배 점적 관수 시 관수량에 따른 4년생, 8년생 묘목의 생장 및 생리 특성을 평가하여, 왕벚나무 컨테이너 재배를 위한 적정 관수 기준을 제시하고자 수행되었다. 연구 결과 관수량 처리에 따른 묘고와 근원직경의 상대생장률의 경우 왕벚나무 4년생 은 288 L/year/tree 처리에서 8년생은 416 L/year/tree 처리에서 가장 높은 값을 나타내었다. 물질생산량과 묘목품질지수 또 한 두 연생 모두 관수처리에 따른 유의적인 차이를 보이면서 4년생은 288 L/year/tree 처리에서 8년생은 416 L/year/tree 처리에서 양호한 생장을 보였다. 뿌리발달 특성 중 총뿌리길이, 평균뿌리직경, 뿌리부피는 두 연생 모두 관수량 처리에 대 해 차이를 보였다. 엽록소함량의 경우 왕벚나무 4년생은 288 L/year/tree 처리에서 8년생은 416 L/year/tree처리에서 가장 높은 활성을 보였다. 본 연구결과를 종합적으로 고려해 볼 때 컨테이너 재배 시 관수량의 차이는 묘목의 형태적 상대생장 률, 물질생장량, 묘목품질, 생리적 반응에 영향을 미치며, 왕벚나무를 컨테이너로 재배 할 시 적절한 관수량은 4년생 묘목 (근원직경 3 cm급)은 288 L/year/tree, 8년생 묘목 (근원직경 7 cm급)은 416 L/year/tree가 적절한 것으로 판단된다.

종가시나무 임분의 솎아베기에 따른 흉고직경 및 재적생장 모니터링

윤준혁,배은지,손영모,전형국,이광수,정수영 경상대학교 농업생명과학연구원 2021 농업생명과학연구 Vol.55 No.4

본 연구는 종가시나무의 솎아베기에 따른 흉고직경 및 재적생장 변화를 위해 수행되었다. 솎아베기 시험구는 재적을 기준으로 약도 및 강도의 처리를 하였고, 생장변화는 솎아베기를 실시하지 않은 대조구와 상대적인 비교를 실시하였다. 솎아베기 실시 7년 후 결과는, 흉고직경의 경우 강도의 솎아베기 처리구가 대조구와 비교하였을 때 뚜렷한 생장차이가 나타났다. 7년간의 정기평균생장량 역시 강도의 솎아베기 처리구가 대조구와 차이가 있음을 알 수 있었고, 약도의 처리구 흉고직경생장 변화는 대조구 비교하였을 때, 통계적으로 유의적 차이가 없는 것으로 나타났다. 7년 후의 재적생장 변화는 처리구별 모두 유의적인 차이를 보이지 않았다. 그리고 정기평균생장량 역시 강도의 처리구가 수치적으로 간벌 후 재적생장량이 높으나, 통계적으로는 유의적 차이가 없음을 알 수 있었다. 결론적으로 종가시나무 임분의 솎아베기 처리에 따른 생장변화는 입목들의 공간 확장에 따라 강도의 처리구에서 흉고직경생장 변화가 나타났다. 그러나 입목본수 감소에 따라 재적생장은 처리구별로 유의적인 차이가 나타나지 않음을 알 수 있었다. This study was conducted to investigate the changes in diameter and volume increment according to thinning treatments of the Quercus glauca stands. The thinning treatments were treated with light and heavy based on volume. Increment changes were compared between the thinning treatments and control group. Seven years later, the diameter of breast height in heavy thinning treatment was significantly different in the DBH increment compared to the control group. The periodic annual increment of the heavy treatment was also different from that of the control group, and the change of diameter increment of the light thinning treatment was not statistically significant when compared with the control group. The volume increment change after 7 years did not show significant difference in treatment groups. And the periodic annual increment of the heavy thinning treatment was numerically high, but there was no significant difference statistically. In conclusion, the increment change by the thinning treatments of the Quercus glauca stands was changed in the diameter of the heavy thinning treatment according to the expansion of the growth space of the standing trees. However, volume increment did not show significant difference by thinning treatments according to the decrease of number of standing trees.

경남 연화산 소나무림의 지위지수 추정

윤준혁,배은지,전형국,손영모,이정환 경상국립대학교 농업생명과학연구원 2021 농업생명과학연구 Vol.55 No.3

본 연구의 목적은 지위지수를 사용하여 연화산 소나무림의 임지생산력을 판단하기 위함이다. 연화산 소나무림의 지위지수는 Chapman-Richards 모델을 활용하여 산정하였다. 그 결과 지위지수는 전국 소나무림 지위지수 분포(8~14)보다 높은 범위(14~18)에 있는 것으로 나타났다. 이는 이지역이 소나무가 생육할 수 있는 최적지임을 알 수 있는 기준이 된다. 조사지 A의 경우, 지위지수가 18로 나타났는데, 이는 임령 30년 기준수고가 18m에 달한다는 의미이다. 그리고 지위지수 18인 소나무림 임분재적은 392㎥/㏊으로 지위지수 14일 때 보다 약 140㎥/㏊ 많은 것이다. 이런 지역이 벌기령(60년)에 달하면 임목수확량은 약 459㎥/㏊, 연평균 재적생장량은 7.7㎥/㏊에 달할 것으로 예측되었다. 연화산 느재 지역의소나무림은 임지생산력이 높아 향후 지속적인 생장 추세가 이어질 것으로 보인다. The purpose of this study was to determine the site productivity of the Pinus densiflora stands in Mt. Yeonhwa using the site index. The site index of P. densiflora stands was calculated using the Chapman-Richards model. As a result, the site index was found to be in the range (14-18) higher than site index (8-14) of national pine forest. It suggests that this area is the optimal growth site for Pinus densiflora. In the case of plot A, the site index was 18. This means that when the tree is 30 years old, the height of dominant tree is 18m. The stand volume of pine forests with a site index of 18 is 392㎥/㏊, which is about 140㎥/㏊ more than that of a site index of 14. If these areas reach the harvesting age (60 years), it is predicted that the stand yields will reach about 459㎥/㏊ and the annual average growth rate will reach 7.7㎥/㏊. As a result, The Pinus densiflora stands in the Neujae area of of Mt. Yeonhwa is expected to grow sustainedly in the future due to its high site productivity.
