摘  要：
盐肤木幼嫩复叶萌发早晚不同 ,其内含可溶性糖、单宁和维生素C的浓度有较大的变幅 ,与角倍蚜的致倍率呈正相关关系 ,氨基酸总量则变化较小。不同产量水平典型样地的调查与分析结果表明 :含氮较高的叶片不利于角倍蚜的寄生 ,而土壤的有机质含量或氮素水平与叶组织的氮浓度有着密切的联系。通过调控寄主林的营养环境 ,削弱盐肤木的抗蚜性 ,可视为提高倍蚜致倍效果的增产新途径

摘  要：
The concentration of some contents in the leaves of Rhus chinensis has a great variation range due to the different breaking period of host tree. These contents including soluble sugar, tannin acid and vitamin C are relevant to the order number of the leaves. The earlier breaking leaves have much more contents than that of the later. But the concentration of amino acid has less relation to the order number of leaves. A serial investigation and analysis showed that the host leaves with higher concentration of nitrogen are much more resistible to the gall aphid than the lower. And the concentration of nitrogen of host tree's leaves has a close relation to the soil. For these evidences, the concentration of nitrogen of host tree's leaves can be regulated by selection the condition of soil and application of fertilizer. The susceptibility or resistance of host tree to gall aphid can be controlled to some extent. Consequently, it could be supposed that a new way to improve the yield of horn gall is actable by means of regulation the susceptibility or resistance of Rhus chinensis to Schlechtendalia chinensis .
