为了给扁桃合理施用微量元素肥料提供科学依据,以9年生‘叶尔羌’扁桃品种为试材,采用彻底刨根、分解取样的方法,研究了生物量的构成特点、各器官微量元素含量和累积分配特性。结果表明,扁桃树总干质量为112.13 kg/株,其中当年新生营养器官占14.14%,果实占7.72%,老营养器官占78.14%;B、Zn、Fe、Mn、Cu的含量均表现为新生器官(叶片、新梢、种仁、青皮、硬壳、细根)高于老营养器官(多年生枝、主干、主根、粗根),但主要在老营养器官中分配累积;扁桃树B、Zn、Fe、Mn、Cu总累积量为B3115.56 mg/株、Zn 2167.36 mg/株、Fe 14242.71 mg/株、Mn 3039.86 mg/株、Cu 519.12 mg/株,每生产1000 kg干商品扁桃需吸收B 227.27 g、Zn 155.87 g、Fe 526.73 g、Mn 163.56 g、Cu 36.08 g。
In order to provide a scientific basis for the rational application of trace element fertilizers to Almond, 9-year-old’Yalqiang’Almond varieties were used as materials to study the compositional characteristics of biomass, the content and accumulation of trace elements in various organs Distribution characteristics. The results showed that the total dry weight of almond trees was 112.13 kg / plant, of which 14.14% were new vegetative organs, 7.72% were fresh fruits and 78.14% were vegetative organs. The contents of B, Zn, Fe, Mn and Cu all showed as newborn The organs (leaves, shoots, seed kernels, green skins, crusts and fine roots) were higher than the old vegetative organs (perennial branches, trunk, main roots and coarse roots), but mainly distributed in old vegetative organs. , The total accumulated amount of Fe, Mn and Cu was B3115.56 mg / plant, Zn 2167.36 mg / plant, Fe 14242.71 mg / plant, Mn 3039.86 mg / plant, Cu 519.12 mg / plant, B 227.27 g, Zn 155.87 g, Fe 526.73 g, Mn 163.56 g, Cu 36.08 g.
