摘　　要：以4年生"霞多丽"葡萄为试材,设置改良霍格兰营养液正常、0.5倍、2倍3个浓度,探讨了不同养分供应量对"霞多丽"葡萄N、P、K吸收量,光合特性,果实品质的影响。结果表明:"霞多丽"葡萄在各个时期改良霍格兰营养液2倍浓度处理下叶片N含量最高,盛花期比0.5倍浓度下N含量高3.02mg·g^(-1),膨大期正常浓度处理下果实N含量最高,为10.26mg·g^(-1),其它时期2倍浓度下N含量最高;2倍浓度下叶片P含量在各个时期均为最高,膨大期时达到最大值,比最低的0.5倍浓度处理高0.5mg·g^(-1),正常浓度下各个时期果实P含量最高,膨大期时为最大值3.41mg·g^(-1);正常浓度下叶片K含量在各个时期高于0.5倍处理,成熟期2倍浓度处理下K含量最高;膨大期和转色期的果实K含量2倍浓度下最高,均为6.00mg·g^(-1),2倍浓度下K含量在成熟期为最高。综合考虑净光合速率、气孔导度、蒸腾速率和胞间二氧化碳浓度等指标,2倍浓度处理下葡萄的光合效率最高,且果实品质较其它处理优,其中可溶性固形物含量分别比0.5倍浓度处理和正常处理高2.1个百分点和0.534个百分点,可滴定酸为0.165%,单宁和总酚含量较高。The four-year-old ＇Chardonnay＇ was used as material. Hoagland nutrient solution of normal, half, two times concentrations were set, the effects of different nutrient supply on nitrogen, phosphorus and potassium uptake, photosynthetic traits and fruit quality in grapes were studied. The results showed that the nitrogen uptake of ＇Chardonnay＇ leaves in times as compared concentration were the highest in different control, in the period of fullblossom the N uptake of double concentration was higher than the control of 0. 5 time about 3. 02 mg ·g^-1. The N uptake of fruit in expand period was the highest with 10. 26 mg·g^-1 ,the content about the control of two times was the highest in other period. The P uptake of leaf under two times control was the highest in different period,in expand period the content was the highest,and higher than 0. 5 time about 0. 5 mg·g^-1. Normol concentration control had the highest P uptake in different period, in expand period the highest content of P was 3. 41 mg ·g^-1. The K uptake of normal control in leaf was higher than 0. 5 time in different period,in mature period,the two times control was the highest. The content of K in fruit were highest in the period of expand and veraison, both of them were 6. 00 mg ·g^-1, and the K uptake in mature period was highest of two times control. Considering the net photosynthetic rate,stomatal conductance, transpiration rate and intercellular CO2 concentration,the photosynthetic efficiency of two times control was the highest. And the fruit quality was better than others. The content of soluble solid was higher than 0. 5 time concentration about 2. 1 percentage point,and higher than normal concentration about 0, 534 percentage point. The content of titratable acid was 0. 165% ,and the content of tannin and total phenols were rather high.
