摘要：

为了探讨机械化种植对木薯生长和土壤理化性状的影响，以‘新选048’、‘华南5号’和‘华南205’ 3个已在生产上大面积推广应用的木薯品种为材料，分别采用机械化种植与传统手工种植2种不同的种植方式，观察测定了不同种植方式木薯的出苗、茎叶生长、叶片生理生化特性、土壤容重、土壤孔隙度、土壤三相比等。结果表明：木薯机械种植不仅能提高木薯发芽率、促进木薯茎叶生长，而且能降低木薯地土壤容重，提高土壤孔隙度，增加土壤通气性。机械化种植比人工种植土壤容重降低0.16 g/cm3，土壤孔隙度提高7.46%，‘新选048’和‘华南205’两个木薯品种种茎发芽率平均提高4.06%。机械化种植是促进木薯生长、改善木薯地土壤理化性状的有效途径。

Abstract:

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.
