Abstract

This study was conducted to investigate the application effects of dried food waste powder (FWP) and mixtures of FWP and organic fertilizer (MFOs) on the growth of lettuce and Chinese cabbage. The physicochemical properties of FWP and MFOs were analyzed. As FWPs containing 3.11% NaCl was applied at 250 kg, 500 kg and 1,000 kg per 10a, growth factors of lettuce and Chinese cabbage, such as a number of leaf, leaf length, leaf width, and dry weight were decreased than those of control appling organic fertilizer. The higher the FWP ratio in the MFOs, the lower the concentrations of N and P2O5 in the MFOs, while the higher the concentration of NaCl. As compared to dry weight of control after treating MFOs, lettuce were not significant in MFOs treatments containing 10~30% FWP, and Chinese cabbage in MFOs treatment containing 10% FWP.

본 연구는 음식물류 폐기물 건조분말(FWP)이 처리된 작물의 생육 효과와 FWP와 유기질비료(OF) 혼합물(MFOs)의 이화학적 특성 및 작물생육효과를 평가하기 위해 수행되었다. 3.11%의 NaCl을 함유하는 FWP를 250, 500 및 1,000 kg/10a 씩 상추와 배추에 처리하였을 때, 작물의 엽수, 엽장, 엽폭, 생물중 및 건물중 등과 같은 작물의 생육지수는 대조구보다 감소하였다. MFOs의 이화학적 특성 분석에서 FWP의 배합비율이 증가할수록 MFOs의 질소 및 인산 함량은 감소하였고, 염분함량은 증가하였다. 상추와 배추에 MFOs와 OF를 각각 처리한 후 작물의 건물중으로 생육을 평가할 때, 상추에서는 FWP 10~30% 범위에서, 배추는 FWP 10% 범위에서 유기질비료처리구(대조구)와 유사한 생육을 나타내었다.
