가축분뇨발효액비 관비 처리 후 상추와 배추의 생육

This study was conducted to investigate the effects of livestock manure liquid fertilizer such as aerobic liquid fertilizer (AF) and anaerobic liquid fertilizer (AAF) on the growth and productivity of lettuce (Lactuca sativa) and Chinese cabbage (Brassica campestis). Treatments were as follow; control, AF-1 (AF 1 L/㎡), AF-2 (AF 2 L/㎡), AF-3 (AF 4 L/㎡), AAF-1 (AAF 1 L/㎡), AAF-2 (AAF 2 L/㎡), and AAF-3 (AAF 4 L/㎡). The EC of commercial substrates in AF and AAF treatments were higher than that of the control. As applied AF and AAF in the lettuce and Chinese cabbage, growth factors like chlorophyll content, leaf number, leaf width, leaf length, fresh weight and dry weight, and the nutrient availability of nutrient content and nutrient uptake increased than those of the control. The application amount of AF and AAF was correlated with growth factors and nutrient availability positively (p≤0.05) in both lettuce and Chinese cabbage. These results indicated that fertigation of AF and AAF was improved the growth of lettuce and Chinese cabbage by promoting an uptake amount of nutrient.
