摘要
为明确自由纺锤形整形修剪模式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调查了自由纺锤形短枝富士天红二号、自由纺锤形长枝富士长富二号2个苹果品种的生长数据,通过SPSS对数据进行统计分析,比较尖削度与主枝轴各生长因素的相关关系及显著性差异,结果表明:自由纺锤形短枝富士天红二号的尖削度与主枝轴各因素均为负相关,其中中心干尖削度与主枝轴总粗度的相关系数为-0.228,与主枝轴平均粗度的相关系数为-0.033,与主枝轴总长度的相关系数为-0.411,与主枝轴平均长度的相关系数为-0.430;而自由纺锤形长枝富士尖削度与各因素均为正相关,具体为中心干尖削度与主枝轴总粗度的相关系数为0.475,与主枝轴平均粗度的相关系数为0.181,与主枝轴总长度的相关系数为0.120,与主枝轴平均长度的相关系数为0.258。
Abstract. The objective of this study is to determine the correlation between the stem taper- ingness and small central shaft by free spindle pruning mode on Fuji apple, by investigating free spindle short shoot Tianhong 2 and free spindle long shoot Changfu 2 in Xingtang County of Hebei Province. SPSS analysis results showed that the stem taperingness on free spindle short shoot had a negative correlation with small central shaft, with the correlation of thestem taperingness among the central shaft total roughness, the central shaft average rough- ness, the central shaft total length, and the central shaft average length being --0. 228, --0. 033, --0. 411 and --0. 430,respectively. while the stem taperingness tended to a posi-tive correlation with free spindle long shoot, reaching 0. 475, 0. 181, 0. 120, and 0. 258 cor- relation of the stem taperingness among the central shaft total roughness the central shaft average roughness, the central shaft total length, and the central shaft average length, respectively. The results provided scientific theoretical basis for guiding planting Fuji apple tree at short anvil dense by pruning technology scientifically.
