| 中文摘要: |
| 对五年生滕稔葡萄进行了六个水平的氮磷钾复合肥对果实生理生化指标和光合速率等的影响试验，测定和比较了果实品质相关指标、以及叶柄氮磷钾含量、叶片净光合速率等。结果表明，果实在施肥量为20 kg/667 m2时综合表现较佳，而且有些果实指标如固酸比，随着施肥量的增加反而明显下降；同时，增加施肥量对叶柄氮磷钾含量和叶片净光合速率没有显著影响。所以，对藤稔葡萄来讲，过量施肥有害无益，建议的施肥量应为20 kg/667 m2。 |
| 英文摘要: |
| NPK compound fertilizer of six levels was top-dressed to ‘Fujiminori’ grapes. Leaf net photosynthetic rate, and related indexes of fruit quality were investigated and compared. The results showed that, the better fertilizer level is 20 kg/667 m2, besides, some indexes of fruit quality, especially the ratio of total soluble solid and titrate acid (TSS/TA) significantly declined when the fertilizer amount was increased. Furthermore, increase fertilizer had no significant effect on leaf photosynthetic rate. Concomitantly, the content of leaf petiole NPK remained unchanged. Thus, more fertilizer will be deleterious but not beneficial. The feasible fertilizer amount may be 20 kg/667 m2 to these two grape cultivars. |
