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。
In order to clarify the correlation between the tree structure and the various factors of Shuji Fujifilm under different plastic pruning patterns, we studied the effects of free-spun short-stem Fuji, slender spindle-spur Fujifilm in Apple Standard Demonstration Garden in Xingtang County, Hebei Province, The trunk taper of the two tree structures and the total coarseness, average roughness, total length and average length of the main axis of the tree were surveyed. SPSS And its small main axis of the growth of the relevant indicators. The results showed that the taper of trunk of Fuji apple with short spindle was negatively correlated with the total thickness, average thickness, total length and average length of its primary axis, but the correlation was not significant. The spindle tapping degree of spindle-spur apple Fuji apple has a negative correlation with the total thickness of its primary branch main axis, and is positively correlated with other factors, and the correlation with the average length of small main branch axles has reached a significant level. The results of this study may provide a scientific basis for guiding the plastic technology of short-rooted shrubs and Fuji apple trees.
