短枝富士苹果树体结构及相关因素分析

为了明确不同整形修剪模式下短枝富士苹果树体结构及各因素间的相关性,在河北省行唐县苹果标准示范园内,分别对自由纺锤型短枝富士、细长纺锤型短枝富士2个树形结构的树干尖削度以及其上着生小主枝轴的总粗度、平均粗度、总长度和平均长度进行了调查,并通过SPSS分析探讨了不同树形树干尖削度与其小主枝轴各生长指标的相关关系。结果表明:自由纺锤型短枝富士苹果的树干尖削度与其着生小主枝轴的总粗度、平均粗度、总长度和平均长度均呈负相关,但相关性均不显著;细长纺锤型短枝富士苹果的树干尖削度与其着生小主枝轴的总粗度呈负相关,与其他因素呈正相关,其中与小主枝轴平均长度的相关性达到了显著水平。本研究结果可为指导矮砧密植短枝富士苹果树整形技术提供科学依据。

Related Factors Analysis on Tree Structures of Short Shoot Fuji Apple

The objective of this study is to determine the correlation between the stem taperingness and small central shaft by different pruning mode on short shoot Fuji apple, which selected two pruning mode, free spindle short shoot, and slender spindle short shoot in Xingtang County of Hebei Province. The stem taperingness and the small central shaft for its total roughness,average roughness,total length, and average length were investigated. By SPSS analysis, this paper analyzed the correlation between the different tree trunk taperingness and its correlation of small central shaft of each. The results showed that the stem taperingness on free spindle short shoot was negative correlation with the total roughness,average roughness,total length,and average length of its small central shaft,but its correlation was neither sig-nificant. While the stem taperingness on slender spindle short shoot was negative correlation with the total roughness of small central shaft,but was positive correlation with other element,of which the correlation between the taperingness and the average length of the small central shaft reached the significant level. The results provided scientific theoretical basis for guiding the short anvil dense planting short shoot Fuji apple tree pruning technology scientifically.
