Abstract: Based on the data collected from field tests and lab experiments, the effect of nitrogen fertilizer on recovery growth of Zoysia japonica trample stressed was studied. The results showed that nitrogen fertilizer was beneficial to the recovery growth of Z. japonica trample stressed. Applying nitrogenous fertilizer with the condition of 8 g/m² could increase the density, plant height, aboveground biomass; and total chlorophyll content was increased significantly than the control.

Key words: Zoysia japonica, nitrogen fertilizer, trample stress, recovery

摘要： 以日本结缕草草坪为试材，采用田间试验，研究在不同践踏胁迫下，施用氮肥对草坪生长的影响。结果表明，施氮肥有利于受践踏草坪的恢复生长，在不同程度践踏胁迫下，施氮素8 g/m2，可不同程度地增加草坪的密度、株高生长量和地上生物量；总叶绿素含量比对照明显增加。
