摘要
Abstract
[ Objective] To find out the distribution and spatial variation patterns of trace elements in the black soil of Central Jilin Province, thus to provide theoretical basis for the rational utilization and degradation of black soil resources. [ Method] Hie black soil was collected from Central Jiiin Province to be analyzed in the laboratory. [Result] Compared with leisure black soil and the second time black soil census, the distribution of soil available micronutrients changed and varied in different regions. The contents of effective iron, zinc., and manganese were low in the middle area and high in the south and north. The content of effective copper showed a decreasing trend from south to north. The content of available micronutrients was lower in the black soil of all the three areas than in the leisure black soil of Gongzhuling, showing a decreasing tendency. The distribution of microelements in the black soil of Centra) Jilin Province showed a spatial variation, different elements had different variation laws. [Conclusion] The appropriate application of zinc and copper can provide guarantee for the yield and income increase in Central Jiiin Province.关键词
