芦苇醋液对‘富士’苹果品质改良作用研究

本文采用田间试验法，研究了芦苇醋液对富士苹果果实品质改良作用，以期为开发绿色环保型果树液体肥提供依据。实验结果表明：芦苇醋液对富士苹果叶片生长和光合特性有直接影响，在适宜浓度时，分别比对照提高叶片的百叶重18.03%，净光合速率325%；进一步研究结果显示：一定浓度（800倍）的芦苇醋液能明显增加套袋或不套袋富士苹果的着色指数、花青素含量、单果重、糖酸比、Vc含量和可溶性固形物含量。由此可见，芦苇醋液作为苹果的品质改良剂具有很好的应用前景。

Studies of Application Effect of Reed Vinegar on Improving Quality of Malus domestica ‘Fuji’

In order to develop a kind of environmental protective liquid fertilizer for apple, quality improvement of reed vinegar on ‘Fuji’(Malus domestica Borkh.) apple have been studied in field. Research result showed, there was a direct effect of reed vinegar on leaf growth and photosynthesis of apple. Under a proper density, hundred leaf weights and net photosynthesis higher than control 18.03% and 325% respectively. further research also indicated that, color index, anthocyanidin content, individual fruit weight, ratio of sugar and acid, Vc content and soluble solids content under certain density(800 times ) have been significant improved compared to control. Form this research we can concluded that reed vinegar would be a good quality improvement fertilizer in apple production.
