| 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. |
