高丛蓝莓冬剪不同留花量对产量和品质的影响

摘要

In order to find out the best number of buds per plant of north high bush blueberry during winter pruning in Jiaodong peninsula, in this paper, we designed 4 treatments to prune the 5-year-old Duke at Jiaonan in Qingdao, and discussed the effects of the fruit yield and quality of north high bush blueberry with different winter pruning, and counted the yield per plant, the rate of fruit which diameter was more than 18 mm, single fruit weight, the hardness of fruit, the soluble solid of fruit and the acidity of fruit to evaluate the fruit yield and quality of north high bush blueberry.The results showed that the fruit yield and quality of north high bush blueberry was best when the number of buds per plant was 4 in Jiaodong peninsula.%为摸索出胶东半岛北高丛蓝莓结果枝最合适的留花量,以4种修剪处理对青岛胶南露天基地5年生公爵进行冬剪疏花试验,研究了冬剪时不同疏花处理对北高丛蓝莓果实产量和品质的影响,并统计了当年不同处理单株产果总重量、果径大于18 mm的果实所占比例、单果重、酸度、硬度、可溶性固形物作为其产量和品质的衡量指标.结果表明:单个结果枝4个花芽的植株,单株产量高、果实品质佳;适合山东胶东半岛蓝莓单个结果枝的留花量为4个.
