Abstract

The present study conducted a comparison on tree growth and productivity of high-density apple orchards by several orchard management systems: making scaffolds by heading-back and thinning out pruning (T-1), maintaining scaffolds upward and bearing shoots downward (T-2), managing branches slightly upward without heading-back (T-3), keeping leaders downward and shoots pending (T-4), maintaining leaders high and branches horizontal with severe pinching (T-5), making leaders with lower branches vigorous and upper shoots pending (T-6), and controlling very high planting density with bending branches (T-7). In conclusion, the orchards of (T-5) and (T-6) management systems showed a superior performance in controlling tree growth, productivity, and quality of fruits. Also, superior management efficiency was obtained in the orchards of (T-5) and (T-6).

수형을 달리하여 재식 이후 일관되게 관리하여온 왜성사과밀식재배에서 재식 후 7-9년차 수체에 대하여 수체생장과 생산성, 그리고 생산된 과실의 품질을 비교하는 일련의 시험을 수행하였다. 과원관리체계의 핵심기술인 수형과 전정방법을 일반대목 개심형(T-1), 왜성대목 썬플러스형(T-2), 세장방추형(T-3), 쏠렉스형(T-4), 세형방추형(T-5), 키큰방추형(T-6), 고밀식형(T-7)으로 구분하여 시행하였다. 상기 비교시험 결과, T-5와 T-6 체계로 전정하고 관리 받은 사과원이 수체생장을 적절히 조절하면서 높은 생산성을 보였고 또한 생산된 과실의 품질도 우수하였다. 또한 경영효율을 비교한 결과에서도, T-5와 T-6 체계에 의해 전정한 사과원이 여타 전정으로 관리된 왜성사과밀식재배에 비해 월등한 결과를 보여주었다.
