摘　　要：通过施加N、P、K和NPK复合肥,对马蹄金Dichondra repens匍匐茎生长的影响进行研究.结果表明:各施肥处理组新茎的生长、茎伸长、茎增长都高于CK组,其中NPK处理组最明显,其余4组依次是P>N>K>CK;各施肥处理组的叶密度、新叶数量都显著高于CK组,其中施加NPK复合肥处理组的叶密度最大,其余4组依次为K>N>P>CK,新叶数量为N>P>K>CK.Taking Dichondra repens as research subject,this thesis had a systematic study of the influence on the growth of D.repens by transplanting and applying N,P,K and NPK compound fertilizer.The results showed that the growth of new stems,the stem elongation and the stem growth in each fertilization treatment group were higher than the CK.The NPK group was the most obvious,followed by P,N,K and CK.The leaf density and the number of new leaves in each fertilization treatment group were significantly larger than the CK.The leaf density in NPK group was the largest and the order of the other groups was K,N,P and CK;the order of the number of new leaves was N,P,K and CK.
