| 摘 要： | 摘要：采用田间试验研究有机肥（基肥）施用量对饲用高粱（Sorghum bicolor）青贮饲料品质的影响。结果表明，在施氮量相等的条件下，随着有机肥施用量的增加，青贮饲料的发酵品质先增高后下降，施用量以75和150 t/hm2为最好；同时，青贮饲料的酸性洗涤纤维和中性洗涤纤维含量不断增加，粗蛋白含量和干物质体外消化率不断下降。综合青贮饲料的发酵品质和饲用品质，饲用高粱青贮利用栽培时，施用有机肥基肥75～150 t/hm2较适宜。

| Abstract: | A field experiment was designed to determine the effect of organic fertilizer application on silage quality of forage sorghum(Sorghum bicolor).The results showed that under the same nitrogen application amount,as organic fertilizer addition increasing,the fermentation quality of silage decreased after initial increase,the best fermentation quality was obtained at the organic fertilizer rates of 75 t/ha and 150 t/ha.Meanwhile,the contents of acid detergent fiber and neutral detergent fiber increased,while th... |
