Abstract

This study was conducted to investigate effects of mixture with dried food waste powder (FWP) and mixed organic fertilizer (MOF) on growth of pakchoi. As compared with non-fertilizer treatment (NF) or control (MOF treatment), growth of pakchoi in FWP treatments (2,500 kg/ha, 5,000 kg/ha, 10,000 kg/ha) was inhibited by salt (NaCl) content in the FWP. In comparison with control, mixtures of MOF and FWP (FWP10, FWP20, and FWP30 treatment) were not significantly different, and their salt content correlated with pakchoi growth factors negatively (P<0.05). Applied of FWP10, (FWP10: 2,500 kg/ha, 2FWP10: 5,000 kg/ha, 3FWP10: 7,500 kg/ha, 4FWP10: 10,000 kg/ha), growth factors of FWP10, 2FWP10 and 3FWP10 treatment were not significantly different than those of chemical fertilizer treatment, and of 4FWP10 decreased. Correlation coefficient between NaCl supply by FWP10 application and growth factor was negative (P<0.01). These results indicated that FWP was used as another source of organic fertilizer, and the organic fertilizers blending with FWP inhibited a pakchoi growth by increase of salt content containing in the them or of salt supplying amount after their application.

본 연구는 음식물류폐기물건조분말(FWP) 및 유기질비료(MOF)와의 혼합물의 처리별 청경채의 생장특성을 비교하기 위해 수행되었다. FWP 처리 후 청경채의 생장 조사 결과, FWP 처리구(2,500 kg/ha, 5,000 kg/ha, 10,000 kg/ha)는 무처리구나 대조구보다 생장이 감소하였다. FWP와 MOF 혼합물(FWP10, FWP20, FWP30) 처리 후 청경채의 생장은 대조구(MOF)와 통계적으로 유의적인 차이를 나타내지 않았으나 혼합물 중 염분 함량과 청경채의 생장 지수는 부의 상관성(P<0.05)을 보였다. FWP와 MOF 혼합물 중에서 FWP10의 처리량(FWP10: 2,500 kg/ha, 2FWP10: 5,000 kg/ha, 3FWP10: 7,500 kg/ha, 4FWP10: 10,000 kg/ha)별 청경채의 생장은 FWP10, 2FWP10, 3FWP10 처리구는 화학비료 처리구와 통계적으로 유의적인 차이를 나타내지 않았고, 4FWP10 처리구는 화학비료 처리구보다 감소하였다. FWP10 시비수준(1~3배)에 따른 염분 공급량과 청경채의 생장 비교 시 부의 상관성(P<0.01)을 나타내었다. 상기 결과들을 종합할 때, 음식물류폐기물건조분말은 유기질비료의 원료로 사용이 가능하며, 음식물류폐기물건조분말이 함유된 유기질비료의 시비에 따른 토양중 염분의 농도가 증가한 경우 청경채의 생장을 감소시킨다는 것을 확인하였다.
