摘要

本研究進行薑荷花基本生産栽培技術之探討，結果顯示：種植密度愈高，切花及種球的單位面積産量愈高，單株産量則愈低，爲求更高生産量，可提高栽植密度至20cm×10cm的行株距。遮光度對切花品質影響爲：70%遮光可增加切花品質，尤可增加切花長度，甚至減少花苞末端綠斑，但過度遮光則降低所生産種球的品質。種球大小對於生長、切花和子球數、品質沒有顯著影響。但種球愈小其子球愈重，直徑在1.2cm以下的小種球，可産生每球平均重達31.3g的子球。但在生長調查中，發現種球所帶之貯藏根愈多，則萌芽開花愈早，切花及種球生産量較多、品質較高，顯示種球所帶之貯藏根數對薑荷花生産的重要性。

These experiments were carried out from 1994 to 1996 to determine the influence of planting densities, shading level, seed corms and number, of storage roots on the production of cut flowers and corms of curcuma. The results were that the higher the planting density was the higher the yield of corms and was the lower the cores produced per plant, and the planting density of 20cm×10cm produced the highest yield of corm. The flowers produced from the treatment of 70% shading appeared the best quality due to these flowers having longer stalks and smaller green area at the end of inflorescence of flowers. In contrast, the quality of coons was low when the plants were grown at heavy shades, The influences of seed coon on plant growth, flower and corm production were insignificantly different, even the plants grown from the seed corms, diameter less than 1.2 cm, still had a good growth and produced good corms, The more the number of storage roots of corm appeared the earlier the flowering and the better the quality of flowers, therefore, the number of storage roots of coons appeared an important factor on the production of cut flowers.
