摘要
2008年夏季,选用豫单2002,采用了随机区组、重复3次设计,在陕西省凤翔县进行了玉米肥料效应实验以研究沼液与氮肥不同配比对玉米产量和品质的影响。结果表明,与传统的施肥方式相比,沼液与氮肥以一定比例配比施肥对青贮玉米增产作用明显,营养品质也显著提高。根据当地的生产实际,以效益为主,综合产量与营养品质,其最佳施肥配比为沼液90 m3.hm-2,碳酸氢铵2568 kg.hm-2。
A field experiment was conducted to study the effects of different proportion application of biogas slurry and nitrogen fertilizer on the yield and nutrients of silage maize in Fengxiang County, The results showed that the biogas slurry mixed with nitrogen fertilizer at a certain proportion could obviously improve the yield and nutritional quality of silage maize comparing with traditional fertilization. The best proportion are 90 m^3 · hm^ -2 of biogas slurry combine with 2568 kg · hm^ -2 of ammonium bicarbonate in integrated considering of local situation.
