摘要
黄土高原地区土壤养分从黄土丘陵区、鄂尔多斯台地风沙区向内环辐射，由低增高；但是黄土高原地区氮磷缺乏，钾肥在一些地区和一些土壤上有显著增产效果，并能提高作物的品质，微量元素在一些土壤上也是缺乏的。今后在肥料上要进行二元或多元复合肥的施用。
The soil nutrient radiated from the loess hills,Oreduos platform sand blown by thestand region to the inner ring,from low to high in the loess plateau region;but be short of N,P inthe loess plateau region,potassium fertilizer has remarkable effect of increase production and raisedquality of plant in some region and some soils,also be short of microelement in some soils.Carry outuse of two and many element complex fertilizer on the fertilizer in the future.
