摘要

臺灣葡萄產期調節催芽處理後，其萌生之新梢為當季結果枝；此時新梢之生長狀況明顯影響日後結果枝生長及花穗的結果情形。因此，農友為確保著果良好，經常以各種葉面施肥方式來進行抑梢處理，但其成效並不穩定且也影響到果穗的發育。本研究目的為探求磷肥、鉀肥及硼酸等3種肥料的實際抑梢效果。由試驗結果顯示，於葉面單獨噴施磷酸一鉀300倍或硼酸800倍，並無顯著的抑梢效果；而碳酸鉀400倍是較佳的葉面抑梢用肥；另噴施過磷酸鈣100倍配合硼酸800倍，則可顯著減少新梢節位數而達抑梢效果。

In Taiwan, the sprouting shoot of 'Kyoho' grapevine after forcing culture treatment was the bearing shoot on season, which development status could make a significant influence to the fruiting and quality of grape in the future. Consequently, the farmers made a practice of foliar fertilization in various ways and try to control the shoot growth for well fruiting set, but the outcome was so changeful and detrimental for quality of fruit cluster, simultaneously. The aims of this study was to make sure what kinds of fertilizer among phosphate, potash and boric acid was effective to control shoot elongation in potted and field experiments. Results was shown that a single foliar spray of potassium dihydrogen phosphate 300x or boric acid 800x were not significantly in shooting control, however the potassium carbonate 400x was better for shooting control. In addition, application of superphosphate 100x with boric acid 800x could significantly reduce the node number and come to the elongation control in length.
