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%.
The effects of different nitrogen rates on the yield of biennial Zoysia japonica were studied. The preliminary results showed that the grass height of Zoysia japonica increased with the increase of nitrogen application rate, and there was a significant positive linear relationship between the grass height and nitrogen application rate. When the amount of nitrogen fertilizer was 8g / m2, the number of panicle per spike, the number of spikelets per plant and the seed yield of Zoysia japonica were the highest, reaching 761kg / hm2 with the germination rate of 96%.
