Abstract
The effects of organic calcium compounds (ACa) tree-spray for late growing stage on the mineral nutrition concentration of fruit, russet and quality in 'Fuji' apple were investigated. Optimum spray concentration of leaves by ACa tree-spray during late growth stage were ranged 125 times among 1,000 times. Also, Optimum concentration of fruits was effected to 125 times. Optimum spray times of leaves effected by ACa 500 times tree-spray during late growth stage were effective in one times (Sept. 25) and three times (Sept. 25, Oct. 5, 15). Also, Optimum times concentration of fruit skin was effected to one times (Sept. 25) and fruit flesh was effected two times (Sept. 25, Oct. 5) and three times (Sept. 25, Oct. 5, 15). Phytotoxicity by tree-spray of ACa concentration and times different not occur to leaf and fruit.
사과 '후지'에서 유기 칼슘화합물(ACa)을 수관살포 농도별 및 생육후반기 횟수별 처리한 후 과실의 칼슘농도, 동녹 발생 및 과실품질에 미치는 영향을 조사한 결과는 다음과 같다. 생육기간중 ACa 수관살포의 적정농도는 엽에는 125배에서 1,000배, 과실에서는 125배 이었다. 생육기간중 ACa 500배 수관살포 적정횟수는 엽에는 1회 (9월 25일) ~ 3회 (9월 25일, 10월 5일, 15일), 과피에는 1회 (9월 25일), 과육에서는 2회 (9월 25일, 10월 5일) ~ 3회(9월 25일, 10월 5일, 15일)이었다. ACa 생육후반기 농도 및 살포 횟수 수관살포에 의한 약해발생은 육안으로 발견하지 못하였다.
