英文摘要	以2年生葡萄为供试作物进行盆栽试验，研究不同用量腐植酸复合肥对葡萄叶片养分积累及其生理指标的影响。结果表明，不同肥料用量对葡萄体内各种生理活动均有明显影响，且与等养分的无机肥相比，腐植酸复合肥表现出明显优势。施肥量低于1．75g／株时，超氧化物歧化酶活性随施肥量的增加显著提高，但当施肥量超过1．75g／株后，超氧化物岐化酶活性开始显著降低；当施肥量为3．50g／株时，过氧化物酶活性达最高，之后再增加肥料用量，腐植酸复合肥处理过氧化物酶活性急剧下降，而无机肥处理过氧化物酶活性变化平缓，对葡萄叶片蒸腾速率的影响与对过氧化物酶活性的影响趋势基本一致；施肥有利于植株叶片养分的积累及吸收利用。; The effects of different application rates of humic acid compound fertilizer （HA） on nutrient accumulation and physiological characteristics of two-year old grape（Kyoho） were studied. The results show that different application rates of HA can affect the physiological activities and nutrient accumulation of grape. Superoxide dismutase（SOD）activity is improved significantly when the application rate of fertilizer is lower than 1.75g/plant, and decreases gradually when the application rate is higher than 1.75g/plant. The peroxidase（POD）activity reaches the highest point when the application rate of fertilizer is 3.50g/plant, then with the increasing of application rate, POD activity in HA treatment is decreased significantly. That of inorganic compound fertilizer treatment changes smoothly. The change of transpiration rate is consistent with that of POD activity. Compared to inorganic fertilizer, HA compound fertilizer can promote N,P, K to be absorbed and utilized by grape.
