典型农田黑土剖面理化性状分析

Investigation of the black soil physical and chemical properties in northeast China

东北黑土区是我国重要的商品粮基地。为了更好地认识和利用黑土,在整个黑土区,从北向南,选取有代表性的剖面采样,对其理化性状进行测定、分析。结果表明,不同地域黑土的理化性状差异显著。阐明农田黑土在整个区域的空间差异。表2,参7。

The black soil area in northeast China is one important grains production base. In order to good understand and utilize the black soil resource, physical and chemical properties in four typical profiles were measured from noah to south in the black soil region.The results showed： there were significant differences of physical and chemical properties in four typical profiles.
