摘要
为选择对花椒窄吉丁具有抗性的优良花椒单株,设置优树选择标准,在陕西凤县12个乡镇72个花椒样地进行了调查。结果表明,大红袍花椒品种对花椒窄吉丁的抗性优于小红袍,花椒抗虫性与树龄、坡向、海拔有关,但地形对花椒的抗虫性影响不显著;经过逐步淘汰、评优,初步选出了对花椒窄吉丁具有抗性的优树7株。
Based on the preliminary investigation of 72 sample lands of Chinese prickly ash (Zanthoxylum bungeanum) in 12 towns, Fengxian County, Shaanxi Province, to select superior individual according selection criteria. The results showed that: Resistance to Agrilus zanthoxylumi of Da Hongpao variety was superior to Xiao Hongpao. Pests Resistance had close relationship with ages, slope directions and altitudes. The influence of topography on pests resistance was not remarkable. Finally 7 superior trees were selected for further study based on elimination and evaluation.
