Chemical Properties of the Greenhouse Soil and Nutrient Contents in Leaves and Stems of Carnation, Lily, and Rose.

카네이션, 백합, 장미 시설재배지 토양중 양분함량 과 품종별 경엽중 양분함량

This study was conducted to investigate tissue nutrient contents and salt accumulation in plastic house soils cultivating lily, rose and carnation. The soil tested had high total salts, available phosphate and exchangeable potassium. The soil cultivating rose had highest salt concentvation followed by chose of carnation and lily. Tissue nutrient contents of lily were higher than chose of carnation and rose. In comparison among cultivars, the nutrient contents were as follows; 'Snow Qeen'>'Le Reve'>'Casa Blanca' in lily; 'Marina'>'Super star'>'Mary Devor'>'Madelon' in carnation; and 'Cocktail'> 'Marina'>'Maderon' in rose. The range of the nutrient contents were: T-N: $1.66\;{\sim}2.35%$, K: $1.73{\sim}2.23%$, Zn: $2.13{\sim}6.43\;mg/kg$, Cu: $3.79{\sim}13.89\;mg/kg$ in carnation; T-N: $0.79{\sim}1.65%$, P: $0.18{\sim}0.44%$, Ca: $0.59{\sim}1.26%$, Mg: $0.21{\sim}0.46%$, Zn: $23.65{\sim}90.30\;mg/kg$, Cu: $0.99{\sim}4.62\;mg/kg$ in lily; and T-N: $0.75{\sim}1.62%$, P: $0.17{\sim}0.30%$, K: $1.60{\sim}2.91%$, Ca: $0.64{\sim}0.94%$, Zn: $24.57{\sim}48.31\;mg/kg$, Cu: $3.10{\sim}9.08\;mg/kg$ in rose. The amount of nutrients uptake per plant was high in order of: K > T-N > Ca > Mg in lily; and T-N > K > Ca > P > Mg in rose.

시설화훼류 재배지 토양의 양분 집적도와 백합, 장미 및 카네이션의 품종별 경엽중 양분함량을 조사하여 토양개량의 기초자료를 얻고자 본시험을 수행하였다. 시설화훼류 재배지 토양은 염류농도, 유효인산, 치환성칼리 함량이 과다하게 집적되어 있는데 화훼류 재배지 별로는 장미 > 카네이션 > 백합재배지의 순으로 컸다. 화훼류 경엽중 양분함량은 작물별로는 백합 > 카네이션 > 장미의 순으로 높았으며, 품종별로는 백합은 'Snow Qeen'>'Le Reve'>'Casa Blanca', 카네이션'Marina'>'Super star'>'Mary Devor'> 'Madelon', 장미는 'Cocktail'> 'Marina'>'Maderon'의 순으로 높았다. 화훼류 경엽중 양분함량은 카네이션은 $T-N:1.66{\sim}2.35%$, $K:1.73{\sim}2.23%$, $Zn:2.13{\sim}6.43\;mg/kg$, $Cu:3.79{\sim}13.89mg/kg$ 범위이었으며 백합은 $T-N:0.79{\sim}1.65%$, $P:0.l8{\sim}0.44%$, $Ca:0.59{\sim}1.26%$, $Mg:0.21{\sim}0.46%$, $Zn:23.65{\sim}90.30mg/kg$, $Cu:0.99{\sim}4.62mg/kg$ 범위이었다. 또한 장미는 $T-N:0.75{\sim}1.62%$, $P:0.17{\sim}0.30%$, $K:1.60{\sim}2.91%$, $Ca:0.64{\sim}0.94%$, $Zn:24.57{\sim}48.31mg/kg$, $Cu:3.10{\sim}9.08mg/kg$ 범위이었다. 백합의 양분흡수량은 K > T-N > Ca > Mg의 순으로 컸으며, 장미의 양분흡수량은 T-N > K > Ca > P > Mg의 순으로 컸다.
