为明确自由纺锤形整形的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整形的‘惠民短枝’‘长富二号’‘华冠’3个苹果品种的树基部粗度、顶端粗度、树高和主枝数、主枝长、主枝粗,分析了3个苹果品种中心干尖削度与其上着生的主枝长、粗的相关性。结果表明,‘惠民短枝’‘华冠’中心干尖削度与主枝长、粗均为负相关,但相关性不显著;‘长富二号’中心干尖削度与主枝长、粗均表现为正相关,其相关性也不显著。
In order to clarify the relationship between the structure of free-spindly apple-shaped apple tree and the various factors, free spindle-shaped ’Huimin spur’ ’Changfu II’ was investigated in Apple Standard Demonstration Park in Xingtang County, Hebei Province, The root thickness, top thickness, tree height and main branch number, main branch length and main branch diameter of three apple varieties of ’Arima’ were analyzed. Branch length, coarse relevance. The results showed that there was a negative correlation between the stem sharpening degree of the ’Huamuan’ center of Huimin short sticks and the main sticks and the rough ones, but the correlation was not significant. The sharpening degree and main stick length of ’Changfu No.2’ , Crude showed a positive correlation, the correlation is not significant.
