| 摘 要： | 采用典型抽样的调查方法,在河北省山区核桃分布区17个县内不同立地条件下,调查了698块标准地,在综合分析影响核桃生长发育的环境因子的基础上,选择了7个立地因子,运用数量化理论Ⅰ方法,构建了河北省山区核桃地力指数模型,编制了河北省山区核桃地力指数表。检验结果表明,达到了精度要求。利用这一模型可对河北省山区核桃立地质量进行数量化评价,为河北省山区核桃的栽培生产管理提供了理论依据。

| Abstract: | This paper used the means of typical samples and investigated 698 sample plots in 17 counties in the mountainous area of Hebei Province under the different condition of local growth.It chosed 7 vertical factors and utilized the method of mathematical quantification theory I in the foundation of analysing comprehensively the influence of walnut growth environment factor.This paper constructed the mountainous area walnut soil fertility index model of Hebei Province,and established the soil fertility index table,the result of examination indicated that the model met the precision requirements.Using this model to appraise the Hebei Province mountainous area walnut vertical quality,it provided the theory basis for Hebei province mountainous area walnut management of cultivation production. |
