摘要
在陇中半干旱区坡耕地大田栽培条件下,以兰州百合为试验材料,研究了硝酸稀土对兰州百合植株的生长特性及鳞茎产量的影响。结果表明,硝酸稀土具有降低兰州百合植株高度、增大茎秆粗度和单叶面积、提高鳞茎产量的作用,其中以浸种和叶面喷施相结合的处理效果最为明显,田间植株高度较对照降低5.4%,茎秆粗度、平均单叶面积分别较对照提高15.3%和13.8%,鳞茎增产率达7.9%。
Under field cultivation condition in semiarid sloping tillage in Longzhong,taking the Lilium davidii var.unicolor as experiment materials,study the effect of the rare earth nitrate on growth characters and bulb yields of Lilium davidii var.unicolor.The results showed that the application of rare earth nitrate reduced height of plants,increased stem diameter and single-leaf area and enhanced the bulb yields,espetially the treatment of combined the two ways of soaking and spraying was most apparent.Field plant height reduced 5.4% than that of control.Stem diameter,the average single leaf area and bulb yields respectively increased 15.3%,13.8% and 7.9% than of the control.
