본 연구에서 토양수분 재분배 모델의 적용가능성을 평가하기 위한 검정에 적용한 것은 무엇인가? | 토양수분 재분배 모델의 적용가능성을 평가하기 위하여 토조 실험결과를 바탕으로 모의결과를 검정하였다. 검정에는 결정계수(R2 : coefficient of determination), 평균제곱오차 (RMSE: Root Mean Square Error), 상대평균절대오차 (RMAE: Relative Mean Absolute Error), Nash-Sutcliffe 모형효율지수 (EI: Efficiency Index)를 적용하였다. R2는 0. | |
시설재배지 생산기술 중정밀관개는 어떤 이로운 효과를 주는가? | , 2008). 시설재배지 생산기술 중정밀관개는 작물이 받는 수분스트레스를 최소화 하고 작물 생육에 필요한 수량을 적기에 투입함으로써 생산량과 품질을 향상시 키고 물 소비량 및 양분의 집적과 용탈을 감소시키는 효과가 있다 (Postel, 2000; Kim et al., 2009). | |
일반적으로 토양수분함량은 무엇의 영향을 받는가? | 일반적으로 토양수분함량은 토양의 물리적 특성에 영향을 받는다 (Hong et al., 2011). |
