With the use of longterm locatiou experiment research method,this paper discussed the influence of nutrient and the effects of corn yield of the application of nitrogen and phosphate fertilizers,green manure and organic fertilizers on the red soil highland.The results showed that： With 96 kg/hm2 of P2O5 on the basis of the same amount of N fertilizer application,the yield of corn was 159 times of the yield of corn with the N fertilizer.It illustrated P was the main obstacle factor of red soil highland,the application of phosphate fertilizer significantly increased the yield.With nitrogen and phosphorus fertilizers and green manure or organic fertilizers,it could significantly increase the content of soil organic matter，improve soil structure，reduce soil unit weight,increase the content of soil available potassium,maintain soil potassium balance.With the Longterm application of phosphate fertilizer,it could significantly increase the content of soil available phosphorus.With phosphorus fertilizer and green manure or organic fertilizers,it could reduce the soil on phosphorus fixation，improve the ability of phosphorus natural supply.There was the fundamental measures of improving fertility of red soil drylands and productive potentialities of land.
