中国土壤中钼的含量与分布规律
- CONTENTS AND DISTRIBUTION OF MO IN SOILS OF CHINA
- 摘要：中国土壤的全钼含量为0.1—6ppm,平均为1.7ppm.钼含量因土壤类型而异,且受成土母质的影响.中国许多土壤具有缺钼和低钼特征.绘制了中国土壤中有效态钼分布图.根据土壤和农作物的钼供给情况,对缺钼土壤和地区进行区划,绘制了缺钼土壤分区图.
- Abstract：Soil Mo contents in soils of China ranges from 0.1 to 6 mg/kg and the variation is primarily due to soil type and secondly, parent material. Soil Mo deficiency was observed in many soils mainly in two regions. Both total and available (oxalic acid and ammonium oxalate extractable) Mo contents are low in loessial soils and alluvial soils along the Yellow River, whereas only available Mo is low in acidic soils in the south of China. Soil available Mo contents was mapped into 5 grades on a scale of 1: 10,000,000. A map of delineation of Mo deficient soils was compiled as well.
- Key words：molybdenum soil Mo deficiency.
