Effects of different amount of manure on soil nutriment,spring maize growth and nutrient absorption were studied in this research.The result indicated that: the organic fertilizer combined with chemical nitrogen fertilizer could increase yield of Spring Maize on dry land but not significantly.In a certain range,with the increasing of organic fertilizer amount applied,100grain weight,rows per ear and dry matter of grain were significantly increased,and photosynthetic characteristics were improved.Yield of T4 treatment with highest amount of organic fertilizer increased by 15.4% and 48.4%,compared with those of T1 treatment with equal chemical nitrogen and CK.Application of manure increased the contents of soil organic matter,total nitrogen,available nitrogen,available phosphorus and available potassium,effectively promoted the absorption of N，P，K by plants,and maize root development was enhanced.
