河北省土壤全钼含量平均为0.61ppm,低于全国平均值(1.7ppm和世界平均值(2.3ppm).土壤有效钼平均0.19ppm,全省68.6%的耕地土壤有效钼低于临界界缺乏值(0.15ppm),含有效钼0.16—0.20ppm的中钼耕地占8.6%,>0.20ppm的高钼耕地占22.8%.本文讨论了成土母质,土壤质地、有机质、碳酸钙、pH等对土壤钼含量消长及分布的影响.根据3982个土壤样品编制了河北土壤有效钼分布图.
The average soil total molybdenum content in Hebei Province was 0.61ppm, lower than the national average of 1.7ppm and the world average (2.3ppm). The available soil active molybdenum was 0.19ppm on average, and 68.6% of available soil available molybdenum in the province was below the critical boundary deficiency (0.15ppm), 8.6% of Molybdenum cultivated land with 0.16-0.20ppm of effective molybdenum and 22.8% of high molybdenum cultivars of> 0.20ppm.This paper discussed the effect of soil parent material, soil texture, organic matter, calcium carbonate, Molybdenum content and distribution.According to 3982 soil samples, a map of soil available molybdenum in Hebei was compiled.
