摘要

本試驗探討草莓春香品種於育苗期進行短日、遮光及斷根等處理後，對草莓植株生育及產量之影響。植株生育處理間差異不顯著，處理苗於10月9~11日開花，11月19~21日開始採收果實，分別較對照區提早22~24天及20~22天，11~2月之早期鮮果產量較對照區顯著提高，早期總產量亦提高62~105%，差異顯著。但是，全期總產量處理間差異則不顯著。根據本試驗結果，遮光及遮光配合斷根兩處理，效果顯著，操作簡便，易爲農友接受，值得推廣應用，以提高單位面積收益。

This experiment was conducted in Hsinchu and Tafu to study the effect of short day, shading and root pruning treated on runner plant in propagation field on flowering and yield in strawberry cv. Harunoka. The runner plants treated with short day, shading and root pruning could f lowering and harvesting 22 days and 20 days earlier than control after planting in grown field. Early fresh fruit yield of treated runner plants were higher than check plot significantly. The early total yield was also 62-105% higher then control significantly. Whereas there were no difference among treat ments of total yield in the whole harvesting season. The results also showed that plant size was no difference among treatments. According to the results, shading and shading with root pruning treatments could be recommended to the strawberry growers.
