| 摘 要： | 通过研究不同氮肥用量对二年生结缕草种子产量的影响,初步结果表明:结缕草的草高随着施氮量的增加而增高,草高与施氮量间存在极显著的正线性关系.当氮肥用量为8g/m2时,结缕草单位面积穗数、穗粒数最多,结缕草种子产量也最高,达到761kg/hm2,发芽率为96%.

| Abstract: | The influence of the nitrogen quantity to the seed yield of two year old Zoysia japonica was studied. The preliminary result showed that the plant-height had significantly positive linear relation to the nitrogen quantity. When nitrogen quantity was 8 g/m~2, the thickness of particles was the largest, so was the grain number per particle, and the yield was 761 kg/hm~2, the germination rate was 96%. |
