摘  要：
为了研究‘陇中1号’肥披碱草早期的生产性能，试验以同德短芒披碱草、‘陇中1号’肥披碱草和野生肥披碱草为研究对象，测定了甘肃天水试验点、甘肃兰州试验点和新疆昌吉试验点2021年和2022年的鲜草产量和干草产量。结果显示，在天水、兰州和昌吉3个试验点，‘陇中1号’肥披碱草两年的平均鲜草产量较同德短芒披碱草分别高71.86%、68.94%和24.92%(P<0.05)，平均干草产量分别高63.03%、70.44%和22.74%(P<0.05)；野生肥披碱草两年的平均鲜草产量较同德短芒披碱草分别高37.47%、28.45%和15.58%(P<0.05)，平均干草产量分别高22.70%、20.53%和8.93%(P<0.05)；‘陇中1号’肥披碱草两年的平均鲜草产量较野生肥披碱草分别高25.01%、35.02%和8.08%(P<0.05)，平均干草产量较野生肥披碱草分别高32.88%、41.41%和10.91%(P<0.05)。综上，‘陇中1号’肥披碱草的草产量最高，说明其具有更大的生产利用价值。

摘  要：
To study the early productivity of the planted E. excelsus Turcz.‘Longzhong NO. 1'grass,this experiment used Elymus breviaristatus Keng cv.Tongde,E. excelsus Turcz.‘Longzhong NO. 1'and wild Elymus excelsus as the test subjects. Fresh and dry grass yields of E. excelsus Turcz.‘Longzhong NO. 1'were measured at the Tianshui experimental site in Gansu,Lanzhou experimental site in Gansu,and Changji experimental site in Xinjiang in 2021 and 2022. The results showed that at the three experimental sites in Tianshui,Lanzhou,and Changji,the average fresh grass yield of E. excelsus Turcz.‘Longzhong NO. 1'for two years was 71.86%,68.94%,and 24.92% higher than that of E. breviaristatus Keng cv.Tongde respectively,and the average dry grass yield was 63.03%,70.44%,and 22.74% higher respectively;the average fresh grass yield of wild Elymus excelsus for two years was 37.47%,28.45%,and 15.58% higher than that of E. breviaristatus Keng cv.Tongde respectively,and the average dry grass yield was 22.70%,20.53%,and 8.93% higher respectively;the average fresh grass yield of E. excelsus Turcz.‘Longzhong NO. 1'for two years was 25.01%,35.02%,and 8.08% higher than that of wild Elymus excelsus respectively, and the average dry grass yield was 32.88%, 41.41%, and 10.91% higher respectively. In summary,E. excelsus Turcz.‘Longzhong NO.1'had the highest grass yield,showing its greater utilitarian value in terms of grass yield.
