Abstract
本試驗以中山月拔五、六年生植株為供試材料，以尿素（46％）及益收生長素（39.5％）等二種藥劑噴施，二年試驗結果，發現在不同氣候環境下各處理間對促進落葉效果與產量有關。尿素25％試區，落葉率高，枝條損傷嚴重，影響萌芽及產量，而以尿素6.25％處理區較適宜，產量也高，平均落葉率達36.1％，新梢乾枯20.3公分，處理後12─14天即可萌芽，單株產量達39.8公斤，果粒重94.8公克，處理間增產45─51％。品質差異不甚顯著。
In this study, the processing Guava, Five or six years old of Chung Sun Yueh Pa, and two chemicals, 46% Urea and 39.5% Ethrel, were used. The results from two-year experiments revealed that different applicationtimings and chemical concentrat onis were closely related to defoliation and production of processing guava under different climate conditions. New shoots were caused severe defoliation and injury, and productivity was also low when 25% urea was applied. 6.25% urea was the best concentration with 36.1% defoliation and only 20.3cm dieback on new shoot. Buds initiated again 12-14 days after spraying of 6.25% urea. Yield of year was 39.8kg per tree with a average of 94.8g per fruit in 6.25% urea treatment, resulting a 45-51% yield increase compared to other treatments. Difference of fruit quality between treatments was not significant.
