| 摘 要： | 采用小区试验方式,在管理、密度一致的条件下,对奥玉5102和农大3188两个青贮玉米品种进行了追施纯氮300、375、450、525kg/hm24个水平的施肥试验研究。结果表明：4个施肥处理水平对夏播青贮玉米的物候期、草产量无显著影响;纯氮300kg/hm2水平的株高最高、绿叶比例最大、单株重最大,成本最低;纯氮525kg/hm2水平的植株成活率最高。

| Abstract: | District on a pilot basis by the management,under the same density,Aoyu 5102 and nongda 3188 two varieties of silage corn were fertilized nitrogen 300,375,450,525 kg/hm2 respectively.The results showed that 4 fertilization levels of the summer corns' phenology and yield had no significant effect on the grass;nitrogen level of 300 kg/hm2 had maximum height,largest proportion of green leaves,maximum weight per plant,and lowest cost;nitrogen 525 kg/hm2 level had the highest survival rate of plants. |
