以三倍体狗牙根为材料，研究施氮量和施氮频率对成坪速度、成坪质量及对杂草竞争力进行综合评价。结果表明，施氮量以4g/m2×4次/月成坪快，质量佳，杂草出现率低。施氮频率以4次/月较好。一次施氮量在3周内以4g/m2建坪速度快，质量高。低施氮频率时则以8g/m2为佳。
The triploid bermudagrass was used as material to study the nitrogen application rate and nitrogen application frequency to evaluate the forming speed, the quality and the weed competitiveness. The results showed that the nitrogen application rate was 4g / m2 × 4 times / month, the quality was good, and the incidence of weeds was low. Nitrogen frequency to 4 times / month is better. A nitrogen rate in 3 weeks to 4g / m2 Ping building speed, high quality. Low nitrogen application rate is better when 8g / m2.
