摘  要:
采用3种方式对天然黑果枸杞进行了整形修剪试验。研究表明,整形修剪一方面使黑果枸杞短结果枝比例增加,最高达到50.8%,另一方面使结果枝分布均匀;树高、地径和冠幅生长指标的增长量与修剪最具相关性的是冠幅(R2为0.965);3种修剪方式即保留丛生枝1枚(Ⅰ)、3枚(Ⅱ)、5枚(Ⅲ)和不修剪7枚(CK)相比,修剪方式Ⅲ的单株鲜果产量增加量和百果重最高,分别为29.0 g.a-1和23.8 g。

摘  要:
Three kinds of methods were adopted on the pruning of natural Lycium ruthenicum.The proportion of shorter fruit bearing banches increased after pruning with a maximum value of 50.8%.The pruning made the distribution of fruit bearing branches more even.Crown growth was mostly correlated to the pruning(R2=0.965) compared to the tree height and.Among three kinds of pruning method,i.e.,retaining 1(Ⅰ),3(Ⅱ) and 5(Ⅲ) overgrowing branches,the yield of fresh fruit of a single plant and 100-fruit were the highest in the last pruning method,and with the values of 29.0 g per year and 23.8 g respectively.
