通过研究木薯对中微量元素的吸收规律,得到了木薯中微量营养元素的丰缺指标.对广东、广西木薯主产区110个土壤样品中微量元素含量进行测定,发现土壤微量元素含量处在缺乏水平.种植木薯除施用氮磷钾肥料的同时还应加大中微肥的施用,来解决土壤中缺乏的状况.

Pot trials were conducted to study the effects of secondary-micro nutrients on growth and development of cassava, thus searching for their critical criterion. Meanwhile, 110 soil samples were collected from major cassava growing regions in both Guangdong and Guangxi for testing status of main secondary-micro nutrients, through which it was clear that Cu, Zn, Mn were under deficient level. These results indicated that in order to improve fertilization efficiency in cassava production, fertilizers with secondary-micro nutrients should be applied apart from NPK.
