【摘要】 本文主要报道张家口半干旱地区龙眼葡萄浆果可溶性固形物与早期产量、果/梢比及单位蔓截面积载果量的相关性。研究表明,浆果可溶性固形物含量与株产、果/梢比、单位蔓截面负载果实量呈极显著负相关。在13～19度浆果可溶性固形物范围内,3～5年生单株产量越高,浆果品质越低。而适当地控制单株产量是提高浆果品质的关键。更多还原

【Abstract】 The results of the present study showed very significant negative correlations between the total soluble solids content ( TSS ) , yield, fruit-shoot ratio and the ratio of fruit to trunk cross-sectional area. With an increase in yield,there was a lowering of the quality of the grape juice on 3 ~ 5 year-old plants within the range of 13~19% of TSS.There-fore, appropriate control of crop size is one of the key factors in the improvement of grape juice quality.更多还原
