Grey relational degree analysis was adopted to investigate the influence of soil nutrient content of 3 types of soil on wheat yield in Huaibei region.The results showed: important factors influencing ear number per hm2,grain number per ear,1000-grain weight and grain yield were respectively available phosphorus,available potassium and alkali-hydrolyzed N and organic matter in alkalescency silty sand soil;available phosphorus,available potassium,alkali-hydrolyzed N and available potassium in silti-subsurface layer loam soil, available potassium,available phosphorus,alkali-hydrolyzed N and alkali-hydrolyzed N in silt.Furthermore,3 fertilization schemes was outlined according to the influence level of the 3 necessary elements on wheat.
