摘　　要：通过箱式砂砾培养法,对阳春砂(Amomum villosum Lour.)进行不同营养条件的栽培实验,研究氮、磷、钾、钙、硼、锌6种不同矿质元素丰缺时对植株生长发育的影响。结果显示,在6种不同的矿质元素中,当氮为15.0 mmol/L、磷1.0 mmol/L、钾6.0 mmol/L、钙0.5 mmol/L、锌8.0×10^(-5)mmol/L、硼0.46 mmol/L时,能满足阳春砂植株基本的生长与发育;10.0 mmol/L的磷、8.0×10^(-3)mmol/L的锌以及0.46 mmol/L的硼,可促进植株的生长发育;而施用50.0 mmol/L的氮、6.0×10^(2)mmol/L的钾以及50.0 mmol/L的钙时,则会对植株的生长发育产生极大的毒害作用。因此阳春砂植株生长与发育过程中矿质元素应合理施用。A series of cultivation experiments under different nutrient conditions were carried out on Amomum villosum Lour. plants through sand culture. The effects of nitrogen(N), phosphorus(P), potassium(K),calcium(Ca), boron(B), and zinc(Zn) concentrations on the growth and development of A. villosum were studied. Results showed that 15.0 mmol/L N, 1.0 mmol/L P, 6.0 mmol/L K, 0.5 mmol/L Ca, 8.0 × 10^(-5)mmol/L Zn,and 0.46 mmol/L B were sufficient for the growth and development of plants, and 10.0 mmol/L P, 8.0 ×10^(-3)mmol/L Zn, and 0.46 mmol/L B showed better performance. However, harmful symptoms appeared when the nutrient concentrations were increased to 50.0 mmol/L N, 6.0 × 10^(2) mmol/L K, and 50.0 mmol/L Ca. Therefore, reasonable concentrations of mineral salts for fertilization should be used during the growth and development stages of A. villosum.
