This study investigated the effects of mechanization cultivation on the growth of cassava and the physical and chemical character of soil. The cassava cultivar ‘Xinxuan 048’, SC5 and SC205 which had been produced on the wide use of large area was used as materials, and the mechanization cultivation and traditional manual cultivation were compared in the studies. The emergence, the growth of stem and leaf, the leaf physiological and biochemical characteristics, the unit weight, the hole percent and the soil three phases were analyzed during the experiment. Results showed that, not only can the mechanization cultivation promote the germination percentage, promote the stems and leaves of cassava growth but also decrease the soil unit weight, increase the holes percent of soil, promote microbe activity in the soil. Mechanized planting compared with hand planting, the soil bulk density decreased 0.16 g/cm3, soil porosity increased 7.46%, the germination rate of seed-stem increased 4.06%. It was effective way to promote cassava growth, improving the soil physical and chemical character.
