Abstract

BACKGROUND: Recently, as the consumption of fresh jujube is increased, fertilizer in jujube cultivation is excessively used to supply nutrient for large fruit produce. This study was conducted to obtain the useful data related to optimum nutrient management technique for fresh jujube cultivation. METHODS AND RESULTS: Nutrient contents of the jujube orchard soils were investigated at 30 different jujube orchards in Boeun, Chungbuk. Soil samples were collected from the different orchards in June, both 2012 and 2013. Soil chemical properties such as pH, organic matter, available phosphate, and exchangeable potassium, calcium, and magnesium were analyzed. Soil available phosphates in optimum level for jujube cultivation were 7% and 13% of total samples in the 2011 and 2012 respectively, and 73% and 57% were higher than optimum level. In Exchangeable K, 37%, 30% were optimum level, 63%, 67% were higher in the year 2011 and 2012 respectively. CONCLUSION: These results showed that nutrient contents of soils were accumulated in jujube orchard of Boeun area. Especially, available phosphate and exchangeable potassium were greatly higher than their optimum level for jujube cultivation respectively.

생 대추 재배에 적합한 양분관리를 위한 기초 자료를 얻고자 2011년과 2012년에 보은군 일원 서로 다른 30개 지점에서 토양 화학성을 조사하였다. 조사 토양에 대한 pH 적정범위 분포율은 2011년도 및 2012년도에 각각 27% 및 33%였고, 유기물의 분포율은 두해 모두 30%였다. 유효인산의 적정범위 분포율은 각각 7% 및 13%였고, 적정범위 이상이 각각 73% 및 57%였다. 치환성 K의 적정범위 분포율은 각각 37% 및 30%였고, 적정범위 이상이 63% 및 67%였다. 조사지점에 대한 토성 분포비율은 양질사토, 사양토, 미사질양토 및 양토가 각각 10%, 43%, 37% 및 10%이었다.
