作者（2019）在《Analysis on Factors Related with Slender Spindle Shaped Apple Trees》一文中研究指出：[Objectives] This study was to determine the correlations of stem taperingness with small central shaft total roughness,average roughness,total length,and average length by slender spindle pruning mode on different apple cultivars. [Methods]A total of 2 tree structures were selected,namely,the slender spindleshaped Zhongqiuwang from Shen County of Hebei Province and slender spindle-shaped short shoot Fuji from Xingtang County of Hebei Province,to investigate the growth indicators of the small central shafts. SPSS analysis was used to compare the correlations between the taperingness with the growth factors of the small central shafts. [Results]The stem taperingness on slender spindle-shaped Zhongqiuwang was positively correlated with the various growth factors of the small central shaft,and the difference in the positive correlation with average roughness reached the extremely significant level. The stem taperingness of slender spindle-shaped short shoot Fuji was negatively correlated with the total roughness of small central shaft,but was positively correlated with the average roughness,total length and average length. [Conclusions] The results provided scientific and theoretical basis for guiding the dense planting of dwarfing apple tree pruning technology.
