摘要
为探究高寒地区建植一年生禾本科和豆科饲草混播饲草地的最佳组合及比例,以燕麦、饲用豌豆、箭筈豌豆为试验对象,设置不同混播组合及比例,对饲草生产性能、营养品质及土壤养分等指标进行测定分析,采用灰色关联度综合评价。结果表明:燕麦(Avena sativa)与箭筈豌豆(Vicia sativa)、饲用豌豆(Pisum sativa)混播时,各混播组合鲜、干重较单播燕麦略有降低,高于两种单播豆科处理。随着各混播豆科饲草比例增加,饲草粗蛋白含量升高,而酸性洗涤纤维、中性洗涤纤维含量均降低,土壤中全磷、有机碳的含量呈增加趋势。通过灰色关联度评价对混播草地饲草产量及品质指标进行综合判定,各混播组合中燕麦+箭筈豌豆(7∶3)处理、燕麦+饲用豌豆(6∶4)处理的综合评价较高,鲜、干草产量与饲草营养品质较优,适合在三江源区一年生混播饲草地建植应用。
This study aimed to explore the best combination and proportion of mixed forage land of annual gramineae and leguminous forage.The production performance,nutrient quality,and soil nutrients of Avena sativa,Pisum sativa,and Vicia sativa were analyzed with different mixed sowing combinations and ratios and evaluated comprehensively by grey correlation degree.The results showed that the fresh and dry weight of Avena sativa mixed with Vicia sativa and Pisum sativa was slightly lower than that of unicast Avena sativa,and higher than that of the two unicast legumes.With the increase of the proportion of mixed legume forage,the crude protein content of the forage increased,while the acid detergent fiber and neutral detergent fiber contents decreased,and the contents of total phosphorus and organic carbon in soil showed an increasing trend.By grey relational comprehensive evaluation to the mixed seeding grass forage yield and quality indexes comprehensive judgment,the mixed portfolio,Avena sativa+Vicia sativa(7∶3)processing,Avena sativa+Pisum sativa(6∶4)dealing with the comprehensive evaluation of high,fresh,hay yield and forage grass has better nutritional quality,suitable for in the three-river source area annual mixed planting forage grassland application.
