| 摘 要： | 为了探讨施肥对青贮玉米原料及青贮饲料的影响,在撒施羊粪的田间,青贮玉米栽培管理时,分别单独施用氮肥（N-150kg/hm 2）、磷肥（P2O5-120kg/hm 2）、钾肥（K2O-150kg/hm 2）,以不施用化肥为对照,经田间测产和取样,并对其青贮发酵后进行分析。结果表明,增施氮肥能极显著提高青贮玉米产量（P<0.01）,Milk2006奶亩指数显著高于单施磷钾肥和对照处理（P<0.05）;增施钾肥显著提高了青贮玉米的产量（P<0.05）。增施氮肥除了提高玉米青贮饲料氨态氮含量外（P<0.05）,玉米青贮饲料的其他发酵品质参数差异不显著。青贮不仅保存了原料的养分,同时降低了硝酸盐含量。

| Abstract: | The effects of fertilizer N (150kg/hm 2), P2O5 (120kg/hm 2), and K2O (150kg/hm 2) on maize raw material and silage at sheep manured soil were studied. The results indicated that the yields of maize silage were increased significantly (P<0.01) with the N fertilizer, which had the higher milk per mu index compared that of the CK, P2O5 and K2O (P<0.05). Compared to the treatments of CK and P2O5, the yield of maize with K2O application increased significantly (P<0.05). The fermentative quality of silage maize had no significant difference except achiving a higher ammonia nitrogen content of silage with N fertilizer. Silage not only preserved the nutrient content of the maize raw materials, but also reduced the nitrate content. |
