the law of soil erosion blackland of Changbei mountain
northeastern China
was expounded in this paper
and the conservation and yield increasing benefit under different controlling measures in hilly sloping field of national commodity grain base were analyzed. The effective measures for transforming middle and low yield field and increasing the agricultural developing Stamina were proposed. The achievemment of this experiment had a great value for popularizaton and utilization
