| 摘 要： | 依据贵州省乌蒙山区的气候特点和牧草种植需要,用北林202紫花苜蓿与黔南扁穗雀麦、黔草4号鸭茅分别进行混播试验,从生育期、产量、营养品质、饲用价值等方面对混播群体与3种牧草单播进行比较分析,探讨北林202紫花苜蓿与黔南扁穗雀麦、黔草4号鸭茅这2种不同禾本科牧草混播后的增产效益。结果表明,混播群体较黔南扁穗雀麦、黔草4号鸭茅单播牧草鲜草产量分别提高7.57%、8.00%,经济效益分别提高14.01%、15.34%。综上所述,北林202紫花苜蓿与禾本科牧草混播,既能提高牧草产量,又可提升牧草饲用价值,获得了较好的经济效益。

Effect of Mixed Seeding of Medicago sativa with Bromus catharticus and Dactylis glomerata |
| |
| Abstract: | Based on the climate characteristics and the forage requirement in Wumeng mountain area of Guizhou Province, the mixed seeding experiments of Medicago sativa cv. Beilin 202 with Bromus catharticus cv. Qiannan and Dactylis glomerata cv.Qiancao No.4 were conducted, respectively. Furthermore, in order to evaluate the increasing production benefit of Medicago sativa cv. Beilin 202 with Bromus catharticus cv. Qiannan and Dactylis glomerata cv. Qiancao No.4 in mixed seeding system, a comparative analysis was carried out between the mixed seeding population and the single seeding mode of the three kinds of forage grass from the aspects of growth period, yield, nutritional quality and feeding value. The results showed that the yield of mixed seeding grass with Medicago sativa cv. Beilin 202 was increased by 7.57% and 8.00% than that of the single seeding of Bromus catharticus cv. Qiannan and Dactylis glomerata cv. Qiancao No.4, respectively, and the economic benefits were increased by 14.01% and 15.34%, respectively. In conclusion, the mixed seeding of Medicago sativa cv. Beilin 202 with gramineous forage not only increases the herbage yield but also elevates the herbage feed value, and good economic benefit is gained. |
