以5年生“赤霞珠”葡萄为试材,研究了不同叶幕高度的“厂字”架式对酿酒葡萄光合效率和果实品质的影响,以提高贺兰山东麓酿酒葡萄的果实品质。结果表明:与“独龙蔓”架式相比,“厂字”架式处理提高了酿酒葡萄叶片比叶重和叶绿素含量,120cm和150cm叶幕高度的“厂字”架式处理显著提高了叶片光合效率、果实中总糖、花色素和总酚含量,没有显著影响平均单果重和可滴定酸含量,使果实品质得到显著提高。因此,在宁夏酿酒葡萄产区,120cm叶幕高度“厂字”架式可通过调节叶片的发育和光合效率,进而显著提高了酿酒葡萄果实的品质。
The effects of different characters of “Cui Zi” frame on the photosynthetic efficiency and fruit quality of wine grape were studied with 5-year-old “Cabernet Sauvignon” grapes as test material to improve the quality of wine grape Fruit quality. The results showed that compared with the “Dulong Man” frame type, the “frame word” rack treatment increased the specific leaf weight and chlorophyll content of the grape leaves, and the height of the leaf curtain at 120 cm and 150 cm The leaf photosynthetic efficiency, total sugar, anthocyanin and total phenolic content of fruit in the treatment did not significantly affect the average fruit weight and titratable acid content, and the fruit quality was significantly improved. Therefore, in the Ningxia wine grape region, 120cm leaf curtain height “plant characters ” frame can significantly improve the quality of wine grape by adjusting leaf development and photosynthetic efficiency.
