山东枣树栽培区的区划研究

Study on cultivation zoning of jujube tree in Shandong

自 1978年开始对山东栽培的近百个省内外枣树良种的生长结果习性和生态适性进行观察、调查 ,结果表明 ,不同的枣树品种 ,对气候、土壤的适应能力相差很大 ,要发挥良种的生产性能 ,实现优质高产 ,必须满足其对气温、日照、降水和土壤等环境因素的要求。根据不同品种类群对生态因素的要求和山东省各地的气候、土壤特点 ,将山东省划分为 6个枣树栽培区 ,并提出每个栽培区发展规划的特点。

The growth and fruiting habit and ecological adaptation of one hundred jujube cultivars were observed and investigated since 1978 The result showed that there were great differences among various varieties In order to make use of good variety's performance and achieve good quality and high yield, the environment factors such as temperature, sunshine, rainfall, soil and so on should be satisfied with its need According to various varieties' need to ecological factors, climate and soil characteristics of different areas, Shandong Province was divided into six cultivation zones, and the characteristics of development programing of each cultivation zone was put forward
