河北省土壤全锰平均值569ppm,低于全国和世界平均值.对5,253个土壤样本用DTPA提取的有效锰平均5.8ppm.全省73.7%的样本,79.8%的耕地有效锰低于临界缺乏值(7ppm).这预示施用锰肥有着巨大的增产潜力.本文讨论了成土母质、土壤质地、碳酸钙、pH、有机质和土壤湿度等对土壤锰含量和消长的影响以及它们之间的统计学关系. The mean total manganese in soils in Hebei Province was 569ppm, lower than the national average and the world average.The average effective manganese extracted by DTPA in 5,253 soil samples was 5.8ppm.About 73.7% of the samples in the province and 79.8% (7ppm), which indicates that there is a huge yield potential for applying manganese fertilizer.This paper discussed the effects of soil parent material, soil texture, calcium carbonate, pH, organic matter and soil moisture on the soil Mn content and its growth and their statistical relationship.
