坡地檬果栽植密度對生育、管理、產量及果品影響之研究

劉銘峰

摘  要

本試驗設於65年定植之愛文檬果園,行株距分6M×6M疏植修剪區,3M×3M密植矮化區及3M×3M密植不修剪對照區。經2年試驗結果顯示:疏植修剪可以減少落果,而由于日照充足,果實著色艷麗。其單位面積產量為密植不修剪對照區之44%。然單株著果數卻高達對照區之230%。而密植矮化強剪會使翌年單株著果數減少61%,果品分析結果,各處理無顯著差異。各種管理作業如施肥、修剪、噴藥等等均與栽植密度呈正比關係。密植時,投資大,管理作業不便,如密植不修剪對照須投資約為疏植區4倍之成本,然只回收約2倍之產量,故坡地檬果栽植之行株距應以6M×6M為理想。


Studies on the Effects of Plant Densities on the Development Management, Fruit Yield and Quality of Mango (Mangifera, indica L.) on Slopeland

M. F. Liou

Summary

        The purpose of this observation was to understand the effect of plant densities and cultural practices on mango tree on slopeland.  The mango trees observed in this experiment were planted in 1976.  The treatments were 6×6 M per plant with pruning, 3×3 M per plant with pruning and 3×3 M per plant without pruning as check, respectively.

        The results obtained from two years’ observation showed that high spacing with pruning increased the number of fruit 2.3 times higher than the ck treatment.  However, only yielded 44% of the ck treatment.  Low spacing with pruning decreased the number of fruit by 61% in the following year.

        Fruit quality analysis of matured fruit have no significantly difference among three treatments.  Cultural practices such as fertilizing, pruning, disease and insect control were positively related to planting spacing.  Consideration on capital investment and operation of management the best density of planting mango tree on slopeland area is 6×6 M per plant.
