以酿酒葡萄“贵人香”为试材,连续2年研究了模式化修剪保留不同叶幕厚度处理对葡萄果实产量、品质和枝条贮藏营养等生长发育指标的影响,以期为葡萄简化修剪技术的研发提供理论依据。结果表明,叶幕厚度90cm处理产量最高,其次为60cm处理,两者无显著性差异,30cm处理最低。叶幕厚度60cm处理果实的可溶性固形物、总糖、糖酸比和维生素C含量均最高,显著高于其他处理,其次为90cm处理,30cm和120cm两个处理最低。可滴定酸含量表现相反趋势。叶幕厚度60cm处理单宁和总酚含量均最高,其次为90cm和30cm处理,120cm处理最低并显著低于其他处理。叶幕厚度60cm、90cm和120cm 3个处理枝条的可溶性糖、淀粉和可溶性蛋白含量均无显著性差异,显著高于30cm处理。2014年叶幕厚度60cm处理的游离氨基酸含量最高,其次为90cm处理,两者无显著性差异,显著高于120cm和30cm处理,30cm处理显著低于其他各处理。综合分析,在辽宁省朝阳市气候条件下,模式化修剪叶幕厚度保留60cm时,贵人香葡萄表现最佳,其次为90cm处理,30cm和120cm处理最差。
The effect of pattern pruning with different leaf thickness treatments on growth and development indexes of grape fruit yield and quality and vegetative storage of branches was studied for two consecutive years with wine grape Provide the theoretical basis for the research and development. The results showed that leaf thickness of 90 cm was the highest, followed by 60 cm. There was no significant difference between the two treatments and the lowest was 30 cm. The soluble solids, total sugar, sugar acid ratio and vitamin C content of leaves with the thickness of 60 cm were the highest, which were significantly higher than those of other treatments, followed by 90 cm and the lowest of 30 cm and 120 cm respectively. Titratable acid content showed the opposite trend. Leaf thickness of 60cm and tannin were the highest, followed by 90cm and 30cm, the lowest was 120cm and significantly lower than the others. There was no significant difference in the content of soluble sugar, starch and soluble protein among the three branches with leaf thickness of 60cm, 90cm and 120cm, which was significantly higher than that of 30cm. In 2014, the content of free amino acids in leaves with the thickness of 60 cm was the highest, followed by 90 cm. There was no significant difference between the two treatments, which was significantly higher than that of 120cm and 30cm treatments. The 30cm treatment was significantly lower than the other treatments. Comprehensive analysis, in the climate conditions in Chaoyang City, Liaoning Province, the pattern of pruning leaves the thickness of the curtain to retain 60cm, Gui elegant grapes best performance, followed by 90cm treatment, 30cm and 120cm treatment worst.
