Abstract:

This study investigated the effects of mechanization cultivation on the root tubers yield of cassava and the fertility of soil. The cassava cultivar ‘Xinxuan 048’, SC5 and SC205 which had been producted on the wide use of large area was used as materials, and the mechanization cultivation and artificial cultivation were compared in the studies. The root tubers yield of cassava and the fertility of soil were analyzed during the experiment. The results showed that, the contents of soil available nitrogen, available phosphorus, available potassium, organic matter and the yield of cassava with mechanization cultivation were significantly higher than those of artificial cultivation. The contents of soil available N, P, K and organic matter increased respectively by 7.23%, 6.27%, 16.76%, 4.46% in ‘Xinxuan 048’, increased respectively by 11.09%, 32.58%, 21.80%, 3.73% in SC5, and increased respectively by 9.21%, 14.28%, 16.80%, 5.21% in SC205. The cassava cultivar ‘Xinxuan 048’, SC5 and SC205 which the root tubers yield increased respectively by 14.02%, 5.86% and16.70%. This showed that the mechanization cultivation play a positive role in improving soil fertility, promoting cassava growth and increasing the yield of cassava, it should be applied extends in the planting of cassava. In addition, the cassava cultivar ‘Xinxuan 048’ and SC205 whose yield increased significantly in the mechanization cultivation, so they are worthy of spreading.
