A desert or sand control method. Water spraying and spreading of solid organic substances are manually or mechanically performed on the surface of a desert or sand in any sequence, or a solution having cohesiveness and adhesion and formed by solid organic substances is directly sprayed. A sand body on the surface of the desert or sand that is sprayed with the solution formed by solid organic substances or spread with the solid organic substances and sprayed with the water is uniformly stirred by using a stirring apparatus, so that the sand body on the surface layer of the desert or sand is modified into a modified sand body. The control method can be directly performed on a desert or sand needing to be controlled, and the sand body modified by means of stirring does not need to be individually paved, so that numerous construction costs are saved, and the construction efficiency is improved. In addition, the process of stirring the surface layer of the desert or sand can also be used as a farming process on th
