本试验通过定期测定以M_7,MM_(106),M_4为中间砧,山定子为基砧的紅星苹果树叶片内矿质营养元素的含量表明:年周期内不同中间砧红星树叶片内矿质营养元素的季节性变化很大,而各砧木之间在同一季节具有一定的差异。M_7中间砧紅星树叶内K、Ca、Mg、Na含量显著高于M_4和MM_(106);而Zn、P、Nn、Ca的含量M_4中间砧树高于MM_(106)和M_7;MM_(106)中间砧叶片中N含量高于M_7和M_4;Fe在各不同中间砧树叶片内含量大致相同。各矮化中间砧红星叶片內矿质营养元素含量虽存在着一定的差异,但在年周期内的变化规律大致相近;各常量元素含量的年周期变化曲线具有特定的模式。
In this study, the content of mineral elements in the leaves of Red Star apple trees with M_7, MM_ (106) and M_4 as the anvil and the mountain statues as the rootstocks were determined regularly. The results showed that the contents of mineral elements in the leaves of Red Star apple Seasonal changes vary greatly, while the rootstocks in the same season have some differences. The contents of K, Ca, Mg and Na in leaves of M_7 interstock were significantly higher than those of M_4 and MM_ (106), while the content of Zn, P, Nn and Ca was higher than that of MM_ (106) and M_7 ) N content in the middle anvil leaves is higher than M_7 and M_4; Fe content in the leaves of different middle anvil leaves is about the same. Although there are some differences in the contents of mineral nutrients in the leaves of Dwarfing Interstocks, the variation regularity in the annual cycle is similar; the annual cycle variation curve of the content of each constant element has a specific pattern.
