| 摘 要： | 在大田情况下，以香茅草为材料，研究了不同施肥水平对香茅草生物量和香茅油产量的影响。结果表明：施肥对香茅草生物量和香茅油产量都有明显的提高，最佳施肥水平在中肥区，即硫酸钾400 kg/hm2，钙镁磷肥1 500 kg/hm2，尿素750 kg/hm2，此施肥水平鲜草产量和香茅油出油量最高，分别达60 622.2 kg/hm2和372.5 L/hm2。

| Abstract: | Lemongrass was selected as materials to study effect of different fertilizer application level on the biomass and citronella oil output under field conditions. The results indicated that a significant increase in biomass and citronella oil output at different fertilization levels was found. The best fertilization level is in the middle fertility zone which is potassium sulphate 400kg/hm2, calcium-magnesium phosphate 1 500 kg/hm2, urea 750 kg/hm2. The grass production and citronella oil output raise the maximum to respectively 60 622.2 kg/hm2 with 372.5 L/hm2 in the middle fertility zone. |
