河北省土壤全锌平均73ppm,低于全国平均值(100ppm),高于世界平均值(50ppm).土壤有效锌平均0.53ppm,全省78.8%的耕地土壤有效锌低于临界缺乏值0.50ppm.微量元素锌是横亘在河北省农林牧业生产面前的潜在障碍因子.本文讨论了成土母质、土壤机械组成、土壤有机质、土壤碳酸钙、土壤有效磷以及水热条件对土壤有效锌消长与分布的影响,确定了它们之间的统计学数量关系.编制了土壤有效锌分布图.根据锌肥的经济效益拟定了土壤有效锌利用分区.
Soil zinc in Hebei Province average 73ppm, lower than the national average (100ppm), higher than the world average (50ppm) .Average soil zinc average 0.53ppm, the province 78.8% of the soil available zinc below the critical shortage of 0.50ppm. Trace elemental zinc is a potential obstacle to the development of agriculture, forestry and animal husbandry in Hebei Province.This paper discussed the effects of soil parent materials, soil mechanical composition, soil organic matter, soil calcium carbonate, soil available phosphorus and hydrothermal conditions on soil Zn depletion and distribution The relationship between them was established and the statistical relationship between them was established.An effective zinc distribution map was compiled and the effective Zinc utilization zones were formulated according to the economic benefits of Zinc fertilizer.
