摘要
为探索钾肥不同施用量对紫云英鲜草产量的影响,进行了6个不同钾肥水平的试验研究.结果表明：紫云英在中等肥力情况下,在施用P2O5 45kg/hm2的基础上,每增施1 kgK2O,增加鲜草73.43～101.4 kg.在福泉市生产条件下最佳施用量为K2O 68kg/hm2.
6 different potassium fertilizer rate were carried on in test aimed to explore the effects of different potassium fertilizer rate on yield of Astragalus sinicus L.. The resutls showed that under the condition of medium fertility soil, with application of P2O5 by 45kg/hm2, increase lkg of K2O could increase fresh Astragalus sinicus L. by 73.43-101.4kg. Its indicated that the best fertilizer rate was K2O 68kg/hm2 under the condition of Fuquan.
