通过对河北张家口丘陵地区果树引种试验可以得知,果树在引种的时候会受到品种与地域的影响。通过对多个果树品种进行对比试验从而培育出适合该地区发展的果树品种,这些果树品种包括石榴、枣树等,并且在抗旱、耐贫中起到重要的作用。对果树的引种从根本上为河北张家口生态林业的发展奠定基础,从根本上实现生态环境的恢复以及建设,为建设河北张家口物质资源基础提供理论基础。
Through the introduction of fruit trees in Zhangjiakou hilly areas in Hebei Province, it can be learned that fruit trees will be affected by varieties and regions when introduced. By comparing multiple fruit tree species to cultivate suitable fruit tree species for the development of the region, the fruit tree species include pomegranates, jujube and so on, and plays an important role in drought resistance and poverty alleviation. The introduction of fruit trees fundamentally laid the foundation for the development of ecological forestry in Zhangjiakou of Hebei Province, and fundamentally realized the restoration and construction of ecological environment, which provided the theoretical basis for building the material resources base of Zhangjiakou in Hebei.
