摘　　要：研究了施加N、P、K及NPK复合肥对移栽假俭草(Eremochloa ophiuroides)草丛匍匐茎生长的影响.结果表明,施加NPK复合肥后,假俭草匍匐茎及蘖密度增长明显,各处理结果匍匐茎伸长生长、新枝生长、茎密度、新蘖密度及总蘖密度的大小顺序为NPK复合肥>K肥>N肥>P肥.本研究显示,K肥及NPK复合肥能显著提高假俭草匍匐茎及糵密度.Experimental treatments,i.e.4 treatments of fertilizer applying（applying N,P,K and NPK）,were carried out in this paper.The effect of applying N,P,K and NPK to the stolon growth of the transplanted tuft of Eremochloa ophiuroides was studied in this paper.The treatment of applying NPK had a most significant effect on the stolon elongation,new branch development,stolon density,new tiller density as well as total tiller density,followed by the treatments of applying K,N and P,respectively.The study revealed that the both the stolon and tiller density in E.ophiuroides increased significantly after applying either K or NPK.
