摘要
以多花黑麦草为试验材料,探究有机肥(发酵鸡粪OF)与无机肥(尿素IF)配施对多花黑麦草产量及饲用价值的影响,本研究设置4个处理,即对照组ck(不施肥)、100%IF、50%IF+50%OF、100%OF。结果表明,3个施肥组多花黑麦草的产量和营养价值均显著高于ck,50%IF+50%OF组具有最高的株高、产量、CP和NDF含量,并且鲜草产量高达26166.67 kg/hm^(2),比100%IF处理组和100%OF处理组分别提高了71%和55%。综合分析,在实训牧草场,尿素与发酵鸡粪配合施用能提高多花黑麦草的产量和营养价值。
To explored the effects of different proportions of organic fertilizer(OF:Fermented chicken manure)and inorganic fertilizer(IF:Urea)on the yield and feeding qualities of Italian ryegrass.The study included four treatments:control(CK,no fertilizer),100%IF,50%IF+50%OF and 100%OF.The results showed that the yield and nutritional value of Italian ryegrass in the 3 fertilization treatments were significantly higher than that of CK,the 50%IF+50%OF treatment had the highest plant height,yield,CP and NDF content,and the fresh grass yield reached 26166.67 kg/hm^(2).Compared with 100%IF treatment and 100%OF treatment,the fresh grass yield of 50%IF+50%OF treatment was improved by 71%and 55%,respectively.In conclusion,urea combined with fermented chicken manure can improve the yield and nutritional value of Italian ryegrass.
