选取中厚层黑土、中层黑土、侵蚀黑土、薄层黑土4种典型黑土进行定点定位研究,根据测定结果进行横向和纵向比较,分析黑土障碍因子的形成以及对土壤生产力的影响。

Four typical black soils, black soil medium-thick in soil layer, black soil medium in layer, eroded black soil and black soil thin in layer were selected for stationary study. Based on the results, horizontal and vertical comparisons and analysis of formation of the impedient factors in the black soils and their effect on soil productivity were carried out.
