摘要
本文用86RbCl标记经盆栽和大田设区对枸杞进行了施钾试验,初步结果表明:在富钾的土壤区施氮、磷化肥的同时施用钾肥可增产10%左右,钾肥利用率为8%左右,施钾肥对其它养分的吸收有促进作用,对维持土壤钾素平衡有积极作用.
Potassium application test of Lycium barbarum was done in pots and outdoor plots by means of utilization of indicator Rb_(86) CL. As the initial rsults shown, application of nutrogen and phosphorus along with potassium fertilizers in K-riched soils achieved a output rise of 10%; a potassium use rate of 8% or so, a promotion function of obsorption of the other nutrients and a positive effect on maintaining potassium balance in soils.
