1. a method for arid biogeographic zone Desertification Soil ecological recovery, its step comprises:

  • A. soil sorting;

    divide according to soil particle diameter size 3 ~ 4 grades of hanking by the soil of 5 ~ 30cm by mechanical grading;

    cobble (1) particle diameter is 5 ~ 10mm;

    Granule (2) particle diameter is 0.66 ~ 2.50mm;
