유기성 자원과 혼합유기질비료 혼합물의 특성 및 처리 후 엽채류의 생육 효과

Physicochemical Properties of Mixtures with Mixed Organic Fertilizer and Various Organic Sources and Their Influences on Growth of Two Leaf Vegetables

본 연구는 유기성 자원 중 가축분퇴비(LMC), 가공계분(CPM), 음식물류폐기물건조분말(FWP) 및 아미노산발효부산액(ABF)등과 혼합유기질비료(MOF)의 혼합물의 이화학적 특성의 변화와 작물에 대한 생육을 조사하였다. LMC, FWP 및 MOF의 혼합물(MLF)의 질소, 인산 및 칼륨의 함량은 각각 3.6~3.9%, 2.1~2.2% 및 1.3~1.4%의 범위를나타내었다. MLF3 처리구(60% MOF + 10% LMC + 30% FWP)는 대조구(MOF)보다 약 29% 상추의 건물중이 증가하였다. CPM, FWP, ABF 및 MOF의 혼합물인 MCFA의 질소, 인산, 칼륨의 함량은 각각 4.5~4.7%, 1.7~1.9% 및 1.3~1.4%의범위를 나타내었다. MCFA를 상추와 배추에 처리하였을 경우 MOF와 통계적으로 유의적인 차이를 나타내지 않았다. 이러한 결과는 유기성 자원과 혼합유기질비료의 혼합물인 MLFs와 MCFAs의 시비는 상추와 배추 재배에서 혼합유기질비료(MOF)와 유사한 작물생육특성을 나타내어 LMC와 ABF는 유기질비료의 원료로 가능성을 나타내었다.

This study was conducted to evaluate the properties of mixtures of mixed organic fertilizer (MOF) and various organic sources such as livestock manure compost (LMC), dried compost of poultry manure (CPM), dried food waste powder (FWP) and amino acid by-product fertilizer (ABF) and their influences on growth of lettuce and Chinese cabbage. The content of N, P2O5 and K2O of mixture of MOF, LMC and FWP (MLF) was 3.6~3.9%, 2.1~2.2% and 1.3~1.4%, respectively. Lettuce dry weight of MLF3 treatment blending with MOF (60%), LMC (10%) and FWP (30%) was increased by about 29% than that of MOF. The content of N, P2O5 and K2O of mixture of MOF, CPM, FWP and ABF (MCFA) was 4.5~4.7%, 1.7~1.9% and 1.3~1.4%, respectively. Compared to MOF, growth factors of lettuce and Chinese cabbage in the MCFA treatments were not significantly deferent. These results indicated that MLFs and MCFAs, the mixtures of respectively organic sources and MOF, could be applied as orgnic fertilizer in the cultivation of lettuce and Chinese cabbage, and were expected that LMC and ABF might be used as another sources of organic fertilizer.
