论坡耕地不同治理措施的保土增产效益

On the benefit of soil conservation and yield gain in sloping field under different controlling measures

本文通过试验实测结果,论述了东北长白山区黑土地带的水土流失规律。同时对国家商品粮基地的低山丘陵区坡耕地,在采取不同治理措施后,保持水土的效果和增产效益进行了分析,以及对如何改造中低产田,增强山区农业发展后劲,提出了有效的防治措施。此试验成果有普遍推广应用的价值,并对实现农业发展新突破,具有重要的战略意义。

Based on the experimental results. the law of soil erosion in 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 achievement of this experiment had a great value for popularization and utilization, and for new steps of agriculture development.
