Abstract: The response of seed components and yield to different applied nitrogen rates in tall fescue were studied at biological experiment farm of Ningxia agricultural and forestry academy in Yingchuan city of Ningxia during 1999 2000.The results indicated that the optimum applied rate of nitrogen was 90 kg/hm2(45 kg/hm2 in autumn +45 kg/hm2 in spring) and it's seed yield was 3533 kg/hm2.In contrast with CK(0 kg/hm2 in autumn +0 kg/hm2 in spring),the fertile tillers/m2,spikelets per fertile tillers,florets per spikelets,seeds per spikelets were increased.

摘要： 1999年8月～2000年7月在宁夏农林科学院生物中心实验基地研究施肥对草坪型高羊茅种子产量及产量组成的影响.结果表明,施氮肥可显著提高高羊茅种子产量,以施氮量90kg/hm2(秋季45kg/hm2+春季45kg/hm2)种子产量最高,达3533kg/hm2,与对照相比,生殖枝数/m2、小穗数/生殖枝、小花数/小穗、种子数/小穗均显著增加.
