초록
본 연구는 영년생 작물 중 배 재배지의 탄소수지 평가를위하여 전남 나주 욱곡리 배 재배지에서 토양호흡, 초본류의생태계순생산량 그리고 배 과수의 바이오매스와 배 재배지에서의 생태계순교환량을 측정하였다. 2015년 배 재배지의연간 토양호흡량은 약 25.6 ton CO2 ha-1이었다. 바이오매스측정을 통해 측정된 배나무 수체에 저장된 CO2 양은 (-)27.9 ton CO2 ha-1이었으며, 전정된 가지에 저장된 CO2 양은 약(-)12.6 ton CO2 ha-1 yr-1이었다. 배 재배지 임상 하부에 자생하는 초본류 광합성에 의해 흡수된 CO2 양은 (-)5.2 ton CO2 ha-1 yr-1이었다. 이를 배 재배지 단위에서의 CO2 배출량과흡수량으로 구분하여 보면, 연간 1 ha당 약 25.6 ton이 대기중으로 배출되었으며 대기로부터 흡수된 CO2는 약 (-)45.7 ton이었다. 이를 합산하면 연간 약 (-)20.1 ton의 CO2가 대기 중으로부터 배 재배지로 흡수되는 것을 확인할 수 있었다. 이는 미기상학적인 방법을 이용하여 측정한 배 재배지대기와 작물 및 토양권 간의 연간 CO2 교환량 (-)17.8 ton ha-1와 큰 차이를 보이지 않았다. 이러한 다양한 접근 방법을이용한 연구는 배 재배지뿐만 아니라 영년생 작물 재배지 단위에서 농업생태계 구성요소들 간의 CO2 흐름을 파악하여보다 효율적인 탄소수지 평가 연구를 위한 방법론을 제시하고 향후 농업생태계가 탄소 흡수원으로서 인정받기 위한 후속 연구의 기초 데이터로 사용될 수 있을 것으로 예상된다.
Abstract
Objective of this study was to evaluate the carbon budget on 40 years old pear orchard at Naju. For carbon budget assessment, we measured the soil respiration, net ecosystem productivity of herbs, pear biomass and net ecosystem exchange. In 2015, pear orchard released about 25.6 ton CO2 ha-1 by soil respiration. And 27.9 ton CO2 ha-1 was sequestrated by biomass growth. Also about 12.6 ton CO2 ha-1 was stored at pruning branches and about 5.2 ton CO2 ha-1 for photosynthesis of herbs. As a result, 25.6 ton of CO2 per ha is annually released to atmosphere. At the same time about 45.7 ton of CO2 was sequestrated from atmosphere. When it sum up the amount of CO2 release and sequestration, approximately 20.1 ton CO2 ha-1 was sequestrated by pear orchard in 2015, and it showed no significant differences with net ecosystem exchanges (17.8 ton CO2 ha-1 yr-1) by eddy covariance method with the same period. Continuous research using various techniques will help the understanding of CO2 dynamics in agroecosystem and it can be able to present a new methodology for assessment of carbon budget in woody crop field. Futhermore, it is expected that the this study can be used as the basic data to be recognized as a carbon sink.
