| 摘 要： | 施氮肥可明显增加牧草产量,略增加蛋白产量,随着施氮水平的提高,两者都呈现先上升后下降的趋势。施碳铵优于施尿素,合理施肥应为每次刈割后施碳铵821.4kg/hm2,在此种施肥处理下,鲜草、干草、蛋白产量分别为110328.6、14366.0、2110.7kg/hm2,产值可达14342.7元/hm2。

| Abstract: | The results showed that N fertilizer could increase the yield of napiergrass,and slightly improve the protein content of napiergrass.Along with the application level of N increased,the yield and protein content of napiergrass manifested the trend of rising firstly and decline finally.Applying ammonium carbonate is better than carbamide.The reasonable application method is applying 0.821t/hm~2 ammonium carbonate after cutting every time.The yield of fresh grass,dry grass,protein content of dry grass were 110.329,14.366 and 2.111t/hm~2 respectively.And the production value of hybrid napiergrass "Guimu 1" is 14342.7 yuan(RMB)/hm~2. |
