| 中文摘要: |
| 为探索人工种植管理下桂闽引象草的高产高效施肥模式，以氮、磷、钾肥为试验因子，采用“3414”平衡施肥方法对桂闽引象草的高产施肥模式进行研究。结果表明，桂闽引象草通过合理的氮、磷尧钾配比平衡施肥，能够达到较好的生产效果，充分发挥其生产性能，其中以N2P2K3施肥效果最佳，即每公顷施用氮肥300kg、磷肥150kg、钾肥200.1kg，年鲜草产量达262.63（±29.75）t，折合干草产量56.41（±4.03）t，比对照（无肥处理）分别增产118.30%和121.81%；桂闽引象草蛋白质含量为12.15%，比对照增加69.69%，效果显著。 |

| In order to quest an efficient fertilizer application for Pennisetum purpureum cv. Guiminying under the condition of artificial plant and management, using the nitrogen, phosphate and potassium as experimental factors, conducted the study by the way of野3414冶balance fertilization. The result showed that, by introducing the proper proportion of nitrogen, phosphate and potassium application, Pennisetum purpureum cv. Guiminying could have a better productive result, and exerted production performance fully. Among them, the N2P2K3-fertilizer application performed best, namely, nitrogen 300 kg/hm2, phosphate 150 kg/hm2 and potassium 200.1 kg/hm2, and zhe yearly fresh forage yield was up to 262.63 (±29.75)t/hm2, dry mass yield was 56.41 (依4.03)t/hm2, with 118.30% and 121.81% higher respectively by comparison with the control group (none fertilizer).The protein content was 12.15%, and was 69.69% higher than the control group, and the effect was remarkable. |
