| 摘 要： | 饲用玉米以中原单32、龙辐208和高油115三个品种为材料,研究氮肥用量对饲用玉米生物干重和营养能量价值的影响,探讨氮素用量与饲用玉米产量、可消化总养分产量、净能的关系以及各器官占总产量的分配率.结果表明:三个品种生物干重均N250为最佳氮素用量,品种问龙辐208表现最好;不同氮素用量下各器官生物干重分配率品种问存在差异;氮素用量与饲用玉米生物干重、可消化总养分产量和净能之间均呈二次曲线关系.

| Abstract: | The effects of nitrogen application on dry yield and nourishment energy value of silage maize with Zhongyuandan 32,Longfu 208 and Gaoyou 115 were carried out; the relationship between nitrogen application and yield,total digestible nutrients (TDN),net energy (NE) and distribution of every organ accounted for yield in silage maize were investigate too. The results showed that N250 was the optimal nitrogen application on dry yield,Longfu208 was the optimal variety on dry yield. The distribution of organ dry w... |
