摘要： 在西藏日喀则地区,将燕麦(Avena sativa L.)与箭筈豌豆(Vicia sativa L.)种子按不同比例进行混播试验,通过对混收牧草产量和品质的测定分析,研究适宜在当地生长的燕麦与箭筈豌豆的最佳混播比例,以期获得最大的生物产量和营养价值。结果表明:在燕麦播种量不变的情况下,随着箭筈豌豆混播比例的增加,粗蛋白质(CP)含量随之增加,而中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量降低。在49种混播组合中,混播播种量为燕麦210kg·hm-2和箭筈豌豆75kg·hm-2(G1)混播组合的干草产量和营养成分的综合指标最高,可在西藏日喀则地区推广应用。

Abstract: The yield and quality of both Vetch(Avena sativa L.)+Oat(Vicia sativa L.) artificial grassland were measured and analyzed based on forage yield and crude protein(CP),neutral detergent fiber(NDF),acid detergent fiber(ADF).Results showed that mixture sowing was an effective measure to increase and maintain higher yield,and increase crude protein yield per hectare.As the sowing ratio of vetch increased,the content of CP increased but the content of NDF and ADF decreased.The best sowing ratio was 210 kg·hm-2 vetch plus 75 kg·hm-2 oat among the different mixtures.This ratio has higher forage yield and better quality.It is a practical recommendation to introduce in the Shigaste region of Tibet.
