In recent years the jujube has played an important role in making the jujube-probucing areas rich and improving the whole province’s economy. So many farmers prefer to grow this plant. On the basis of the principle of climatic similarity and by using the method of similar distance, a tentative regionlization is made for introducing and popularizing several famous high-quality varieties of the jujube from Cangzhou, Zanhuang Fuping Counties. The aim of this study is to avoid the waste of manpower and material resources resulted from blind introduction and popularization of the jujube.更多还原
