苹果细长纺锤形树体结构及相关因素分析

RELATED FACTORS ANALYSIS ON APPLE TREE STRUCTURES BY SLENDER SPINDLE PRUNING MODE

为明确细长纺锤形整形修剪模式下苹果树体结构与小主枝轴总粗度、均粗度、总长度、均长度之间的相关性,于河北省行唐县和深县苹果标准示范园内分别调查了细长纺锤形中秋王、细长纺锤形短枝富士共2个树形结构的小主枝轴生长数据,通过SPSS分析,比较尖削度与小主枝轴各生长因素的相关关系。结果表明,细长纺锤形中秋王苹果的尖削度与小主枝轴各因素均为正相关,且与平均粗度之间正相关的差异性表现为极显著水平;细长纺锤形短枝富士的尖削度与小主枝轴总粗度为负相关,而与小主枝轴均粗度、总长度、均长度表现为正相关。本研究结果可为指导矮砧密植苹果树整形技术提供科学的理论依据。

The objective of this study is to determine the correlation between the stem taperingness and small central shaft total roughness,average roughness,total length,and average length by slender spindle pruning mode on different apple cuhivar,which selected two cuhivar,such as slender spindle Zhongqiuwang in Shen county of Hebei province and slender spindle short shoot in Xingtang county of Hebei province. By SPSS analysis,The results showed that the stem taperingness on slender spindle Zhongqiuwang was positive correlation with small central shaft,and the correlation is significant at the 0. 01 level,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 the average roughness,the total length,and the average length. The results provided scientific theoretical basis for guiding the short anvil dense planting apple tree pruning technology scientifically.
