Abstract: To explore different cropping system on the effects of the circle of sandstorm sprinkler irrigation farmland soil wind erosion in potato-unimproved-corn crop rotation (PT), corn-unimproved-corn continuous cropping (SF), potato-oatmeal-corn crop rotation (WF) three circle of sprinkler irrigation farmland planting system as the research object, and in the fixed sand (CK) as contrast, before spring collection surface 0-5 cm soil, by screening method was developed for the determination of soil mechanical composition, analysis of soil grain size parameters and particle fractal dimension. Results show that compared with CK, the three cropping system of cultivated land of 0-5 cm soil layer under the sand soil (< 0.1 mm) particles by 12.83%-42.45%, the content of coarse sand particles content increased by 284.12%-502.86%, the phenomenon of soil particles showed obvious coarsening, sorting sex good, kurtosis to sharp narrowing development, serious soil degradation, shows no matter adopt what kind of cropping system all can cause the soil desertification. Compared different cropping systems, SF, WF PT were significantly improved the arable land, 0-5 cm soil layer under the sand soil (< 0.1 mm) particles content, soil particles appear trend of refining, sorting sex good, kurtosis to develop in the sharp narrowing, fractal dimension values increase, showed that corn stubble and after harvesting the potato planting oats in the monsoon season can decrease the surface wind erosion, reduce the loss of arable land, surface soil fine particles. There was no significant difference among the three planting systems, indicating that different planting systems were not enough to make a great difference in the soil particle size distribution of irrigated farmland.
