摘 要 ：2000年9月~2002年7月在北京地区研究施氮对高羊茅(Festuca arundinacea)种子产量组分和产量的影响。结果表明,随着施氮量的增加,生殖枝数/²增加,施氮150 kg/hm²(2001)和120 kg/h²(2002)生殖枝数/²达到最高,施氮量继续增加,生殖枝数/²反而下降;2001和2002年种子产量都随着施氮量的增加而增加,其中以施氮150kg/h²(秋季75kg/h²+春季75kg/h²)种子产量最高,分别为1864 kg/h²和1954 kg/h²。

Abstract:Effect of fertilization-N on tall fescue seed yield and yield components of seed crop were studied in the Beijing area during 2000～2002. The results showed that fertile tiller/m² achieved the maximum quantity when 150 kg/hm² N in 2001 and 120 kg/hm² N in 2002 were applied. However, further increasing of N fertilizer decreased the number of tall fescue fertile tiller per square meter. Maximum seed yields of 1864 kg/hm² and 1954 kg/hm² were garnered when 150 kg/hm² N(Autumn75 kg/hm²+Spring75 kg/hm²)was applied in 2001 and 2002 respectively.
