摘要
为了对火龙果幼苗期的肥水管理提供科学依据,对1年生火龙果幼苗进行了树体营养分析。结果表明,根系中各营养元素含量大小表现为N>K>Ca>P>Mg>Fe>Mn>B>Cu>Zn,主干中各元素含量表现为Ca>K>N>P>Mg>Fe>Mn>B>Zn>Cu,幼茎中各营养元素含量表现为K>Ca>N>P>Mg>Fe>Mn>B>Zn>Cu。不同矿质元素的累积量大小均表现为幼茎>主干>根系,且各部位的矿质元素累积量差异显著。矿质元素的累积与各部位的生物量大小、矿质元素本身的含量和特性密切相关。
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 NKCaPMgFeMnBCuZn in root,CaKNPMgFeMnBZnCu in cutting wood,and KCaNPMgFeMnBZnCu 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 closely related to its content and properties,and biomass of parts in pitaya seedling.
