钼是植物、动物生长发育必不可少的微量营养元素。土壤中钼不足或过量,都将使植物的正常发育受阻,降低农作物的产质量,同时还会导致人、畜发生某种特殊病症。1979～1980年,我们对上海郊区土壤中钼的含量、分布及其有效性作了如下的研究。一、钼的全量与分布上海主要土壤类型有青紫泥(沼泽型)、夹沙泥、黄泥头和沟干泥(草甸型)及滨海盐土等土壤。土壤钼的全量见表1。从土壤分析结果来看,郊区土壤钼的含量普遍偏低。
Molybdenum is a plant, animal growth and development of essential micronutrients. Insufficient or excessive amounts of molybdenum in the soil will obstruct the normal development of the plant and reduce the yield and quality of the crop, and at the same time it will cause certain special diseases in humans and animals. From 1979 to 1980, we studied the content, distribution and availability of molybdenum in the soils of Shanghai suburbs as follows. First, the total amount of molybdenum and distribution of Shanghai’s main soil types are brucite (marsh type), sand clip, yellow mud and ditch dry mud (meadow type) and coastal saline soil. The total amount of soil molybdenum in Table 1. From the soil analysis results, the suburbs soil molybdenum content is generally low.
