In order to provide theoretical basis of scientific and effective utilization zeolite resource on improving sand land and environmental protection， the effects of adding different particle composition of zeolite to plough layer of sandy loam soil on corn（Zea mays L）growth，NPK absorption were studied in this research.PVC tube with 100 cm long and 10 cm in diameter was adopted to simulate sandy soil column in this experiment with 8 treatments: CK0: No fertilizer+0 g zeolite powder;CK:Fertilizer+0 g zeolite powder;A: Fertilizer+8 g zeolite powder a;B: Fertilizer+8 g zeolite powder b;C: Fertilizer+8 g zeolite powder c;D Fertilizer+8 g zeolite powder d;E: Fertilizer+8 g zeolite powder e;F: Fertilizer +8 g zeolite powder f.Original soil was added in the lower 80 cm pipe layer and the soil mixed fertilizer or zeolite was addid in upper 20 cm pipe layer.Before sowing，the soil columns were irrigated with 500 mL tap water，and during the growing period，they were irrigated 3 times which were 2 000，1 000，1 000 mL respectively.Results showed that: Although there were no differences for plant heights with treatments A，B，C，D，E，F comparing with CK，but their shoot biomasses were higher than that of CK，and the treatments E and F which with the highest particle content in <0.002 mm were significantly higher than that of CK by 71.36% and 63.69% respectively.The results also showed that there was a multiple regression relationship between biomasses and 5 particle composition distributions x1，x2，x3，x4 and x5 which express the percentage of 0.05~0.25 mm，0.02~0.05 mm，0.01~0.02 mm，0.002~0.01 mm and <0.002 mm of powders，which was Y=3.69-0.050 6x1 +0.082 5x2 -0.093 4 x3 -0.009 44 x4 +0.064 86 x5.This equation showed that there was a close relationship between the corn biomasses and particle composition.These coefficients indicated that the biomasses had the strong positive correlation with fine particles，and negative correlation with the coarse particles.Comparing with CK，all treatments of adding powder A，B，C，D，E，F had improved N，K absorption，but only the improved N absorptions for treatment F and improved K for treatments E and F got significant levels，which were improved by 74.52%，63.39% and 63.62%，respectively.There was no influence on P absorption by adding powder.This could be concluded that in this soil condition，only the zeolite powder which clay particle content exceed 39% in the composition could significantly improve corn growth，and increase N，K uptake and utilization.
