| 摘 要： | 土壤速效磷浓度对白三叶地上部的垂直分布影响显著。结果表明,白三叶构件密度、分枝密度、分枝角度及总能量均与土壤速效磷浓度呈极显著正相关,节间长度则与之呈极显著负相关。叶片和匍匐茎的能量与土壤速效磷浓度呈正比。花序的能量则随着有效磷浓度的增加而减少。茎能量分配随着有效磷浓度的增加呈铃形曲线型变化。

| Abstract: | The effect of quick acting phosphorous (QAP) concentration in soil on vertical distribution of T.repens was significant.The positive correlation between the QAP and density of modules,branch density of T.repens ,branching angle and total energy(P<0.01),and the negative one between QAP and the internode length were observed.The caloric content of leaf and stolon increased while that of inflorescence decreased with the rising of QAP.The energy allocation pattern of T.repens was similar to the shape of a bell. |
