| 摘 要： | 2003~2004年采用二次通用旋转组合设计研究了氮、磷、钾不同施用水平对苇状羊茅鲜草产量的影响,获得优化回归模型为y=3426．86 623．07x1 220．75x3;主效应分析表明,增施氮、钾肥的增产效果十分明显,而增施磷肥的作用很小。经模拟寻优,获得年产鲜草4 864kg／667m2的施肥方案为每667m2施纯N 50kg、纯K2O 55kg。

| Abstract: | The mathematical model, y= 3426. 86 623. 07x1 220. 75x3 was built by using the quadratic general rotary combination design to investigate the effects of different application norm of N, P and K on fresh yield of Festuca arundinacea. The results showed that the fresh yield was significantly improved by applying of N and K, and 4864kg/667m2 of fresh yield can be gained by applying 50kg/667m2 of pure N and 55kg/667m2 of pure K2O. |
