摘要

本試驗旨在探討香椿利用密植栽培及修剪方式，對其樹體生長及幼嫩葉片採收產量之影響，以達到經濟栽培目的。在3種不同種植密度處理下，以行株距1.2公尺x1.2公尺者，植株葉片以及萌芽數較多，其產量亦隨之而增加。不同栽培密度處理對香椿複葉長度及複葉上之羽狀小葉發育並無顯著影響。修剪方式改變對香椿之影響較密植方式為大。以修除當年生枝條1/2的方式處理，能產生最大之嫩葉產量，植株高度也最高。在植株離地60cm時處修剪，其萌芽速度快，葉片長度，幼葉採摘長度亦最大。修除當年生全部主枝時，植株整體表現最差，雖然萌芽數多及幼芽生長速度快，但葉片發育明顯受阻，連帶造成食用部份之幼葉產量減少，對栽培有不利影響。

The influence of different plant density and pruning intensity on growth and leaflet yield of Chinese mahogany (Cedrela sinensis Juss.) under field condition were investigated in this experiments.Growth of Chinese mahogany planted in the distance between rows and between plants namely, 1.2M× l.2M, caused the most sprouts and leaf numbers, and than had a rich leaflet yield. The development of paripinnates were not significantly different among 3 planting spaces.Benefits of pruning appeared greater than that of dense planting in Chinese mahogany. The treatment of cutting-in half the current growth caused the most plant height and leaflet yield, whereas the most growing ratio of sprouts and the length of leaves or leaflets resulted from cutting-in 60 cm of plant above ground. It was worse in the performance of plant characters, and less profit by the treatment of pruning current growth on plant to make more sprouts for yielding purpose.
