综合安塞、定西、米脂、河曲4个试区,多年多项目的田间研究结果,分析了不同肥料的增产效益及肥料利用率,计算了不同类型区主要作物的最高施肥量和最佳施肥量及不同R值下的经济合理施肥量。根据雨量和土壤肥力的差异,将黄土丘陵区分为三大片,提出了不同地区的建议施肥量及施用技术。

Both N and P are Iack in the soil in loess hilly region, in which there was a lower and unstable yield, To realize the producing all one’ s own grain and developing agriculture, forestry and stock raising overall, it is necessary to increase material put into the farmland, According to the research results of four experimental areas, the highest yield, a higher fertilizer utilized rate, a better economic efficiency and investing benefit were obtained by atching of N/P with organic manure applied and the result of doing N with manure take second place, The result of experiments points out that the amount of N/P applied decided by different R valure that have been counted with the mathamatic modls gained by the compute. It was advanced that the suggested appliction a mount corresponding R=0-0.5 and R=0.7-1 could be adopted separately in basic farmland and hillside fields in the area with 500mm rain per year and corresponding R=0.7-1 or over 1 a litter could be accepted in basic fareland in the area with 400-450m m rainfall per year,On the base of the above soil fertility and rainfall, loess hilly region was divided into three areas and particular suggestion about amount of fertilizer applied were given respectively.
