摘　　要：为提出拉萨河谷饲草数量性短缺的解决方案,采用多元统计分析法对不同播量、不同灌水方式燕麦、箭筈豌豆混播的干重数据进行对比分析,研究播量与灌水方式对饲草产量的影响。结果表明,在燕麦、箭筈豌豆混播播量一致的情况下,喷灌产量大于畦灌产量;畦灌条件下,燕麦、箭筈豌豆混播225+90 kg/hm^(2)的组合方式产量最高,比传统混播模式增产13.4%;喷灌条件下,燕麦、箭筈豌豆混播255+75 kg/hm^(2)的组合方式产量最高,比传统混播模式增产21.1%。该研究结论可为缓解拉萨河谷饲草数量性短缺提供解决方案,并为高产、稳产的人工饲草发展提供技术支撑。In order to put forward the solution to the quantitative shortage of forage grass in Lhasa River Valley,the dry weight data of oat and arrow pea Mixed Sowing with different sowing amount and irrigation method were compared and analyzed by using multivariate statistical analysis method,and the effects of sowing amount and irrigation method on forage yield were studied.The results showed that the yield of sprinkler irrigation was higher than that of border irrigation under the condition of the same mixed sowing amount of oat and arrow pea;Under border irrigation,oat and arrow pea were mixed at 225+90kg/hm^(2) The combination mode had the highest yield,which was 13.4%higher than the traditional mixed sowing mode;Under the condition of sprinkler irrigation,the mixture of oat and arrow pea was 255+75kg/hm^(2) The combination mode has the highest yield,which is 21.1%higher than the traditional mixed sowing mode.The research conclusion can provide a solution to alleviate the quantitative shortage of forage in Lhasa River Valley,and provide technical support for the development of Artificial Forage with high and stable yield.
