本文研究了黑龙江省17个市县的暗棕壤,白浆土、黑土、黑钙土全锰和有效锰含量。结果表明,这4种土壤全锰含量较高,平均含量为843 ppm,但有效锰含量较低,平均含量为18.6ppm。有效锰含量土壤类型间有显著差异:暗棕壤和白浆土含量较高,平均含量为27.3 ppm 和34.3 ppm;黑土平均含量为9.3 ppm;黑钙土平均含量为3.8 ppm。土壤反应状况、水分状况、CaCO_3和有机质含量都对土壤有效锰含量有影响。
This paper studied the contents of total manganese and available manganese in dark brown soil, albic soil, black soil and chernozem soil in 17 cities and counties in Heilongjiang Province. The results showed that these four kinds of soils had a higher total manganese content with an average content of 843 ppm, but a lower available manganese content with an average content of 18.6 ppm. Available Manganese content Significantly different soil types: Dark brown and Albaline contents were higher with average contents of 27.3 ppm and 34.3 ppm; Blacks with an average content of 9.3 ppm; and Chernozem with an average content of 3.8 ppm. Soil reaction status, water status, CaCO_3 and organic matter content affected soil available Mn content.
