京东板栗生态地球化学环境比配模型与适应性区划

京东板栗是河北省优势农产品之一,由于板栗生长环境的地质地球化学方面的研究较少,致使目前板栗的种植、规划等缺乏理论依据。本文以河北迁西优质板栗产区75件样品为例,分析探讨了温度、地形地貌、岩石土壤类型和部分地球化学元素对优质板栗种植区的控制作用和影响程度,在此基础上建立了上述生态地质地球化学环境因素与板栗之间的比配模型,划分了板栗种植的优质区、适宜区和非适宜区域,为当地板栗种植和规划提供了理论依据和参考。

Ecogeochemical dosing model and adaptability regionalization of Jingdong chestnut

Jingdong chestnut is one of the advantageous agricultural products in Hebei Province;nevertheless,chestnut planting and planning lack theoretical foundation due to insufficient research on geological-geochemical environment for chestnut growth.Based on 75 samples collected from the high-quality production area of chestnut,this paper systematically discusses the temperature,topography,rock soil type and some factors controlling and affecting the high-quality chestnut.On such a basis,the authors established the ecogeochemical dosing model of Jingdong chestnut and classified chestnut planting areas into three kinds,i.e.,qualified areas,suitable areas and unsuitable areas.The results obtained will provide theoretical basis and reference for local chestnut planting and planning.
