Mineral elements in one year old pitaya seeding were analyzed to provide scientific basis for fertilizer and water management.The results showed that mineral elements content showed N>K>Ca>P>Mg>Fe>Mn>B>Cu>Zn in root,Ca>K>N>P>Mg>Fe>Mn>B>Zn>Cu in cutting wood,and K>Ca>N>P>Mg>Fe>Mn>B>Zn>Cu in young stem.Accumulation of mineral elements in young stem was significantly higher than that in other parts,and root had the lowest accumulation of mineral elements,which indicated that accumulation of mineral element clo...
