Abstract The “Vallerani System” invented by Italian experts, a technology of mechanical land preparation, rainfall collecting and afforesting in arid area, was used in experiment and demonstration of afforestation in Chifeng, Inner Mongolia, China. Compared with the traditional manual land preparation and domestic mechanical land preparation for afforestation, the superiority of the "Wallerani System" in land preparation and afforestation was obvious: the rainfall collection efficiency increased 2 times, the soil moisture increased 60%, the soil compact degree reduced 82%, and the survival rate of planted trees increased 30%. Therefore, the "Vallerani System" was successful in land preparation and afforestation in Inner Mongolia, and it was a valuable afforestation technology in China.
