- 摘要:
- 随着生态农业和畜牧业的发展, 寒地牧草的种植正在以迅猛的速度发展, 而牧草施肥相对比较落后。通过试验表明:牧草专用肥可以促进禾本科牧草的生长发育, 使其地上部分生长迅速。 N10P5K3 表现最好, 株高73.7 cm , 增高9.8 cm 。N10P5K3 增产幅度最大, 鲜草增产18 486 kg · hm-2 , 增产率为77.0%;干草增产8 433 kg · hm-2 , 增产率为78.7 %。每kg 肥料增产最高的是 N10P5K3 为61.62 kg , 增加了47.9 kg , 产投比也最好为5.60∶1 。所以N10P5K3 是寒地禾本科牧草生产的最佳施肥配方。
