Abstract

Rose is one of the major cut-flower crops in Korea. A survey was conducted to investigate the chemical properties of soils cultivating rose under plastic film house at 72 farms in Korea. Soil texture distribution of the samples were loam(43%), silty clay loam(19%), and clay loam(17%). The average chemical properties of the surface soils were pH 5.85, electrical conductivity $3.61dS\;m^{-1}$, organic matter $37g\;kg^{-1}$, nitrate nitrogen $205mg\;kg^{-1}$, phosphorous as Av. $P_2O_5$ $844mg\;kg^{-1}$, and exchangeable potassium $1.41cmol_c\;kg^{-1}$. Available phosphate and exchangeable potassium were accumulated at the level higher than the optimum content in over 70% of the surveyed farms. The flower stalk length was positively correlated with the organic matter content in soil, but was negatively correlated with the electrical conductivity in Red Sandra cultivar.

국내 3대 절화류중 하나인 장미의 시설재배지 토양 화학적 특성을 조사하기 위하여 전국 72개 절화 장미 시설 재배 농가를 대상으로 본 조사을 수행하였다. 조사지역의 평균 토성분포는 양토 43%, 미사질식양토 19%, 식양토 17%를 차지하였으며, 표토의 평균 양분함량은 pH 5.85, 전기 전도도 $3.61dS\;m^{-1}$, 유기물 함량 $37g\;kg^{-1}$, 질산태 질소 $205mg\;kg^{-1}$, 유효인산 $844mg\;kg^{-1}$, 그리고 교환성 칼륨 $1.41cmol_c\;kg^{-1}$이었다. 유효인산과 교환성 칼륨은 조사지역의 70% 이상이 적정 수준 이상이었으며, 토양양분함량 중 유기물 함량은 레드 산드라 품종의 절화장과 정의 상관관계를 보였으나 전기 전도도와는 부의 상관관계를 보였다.
