摘 要：
[目的]筛选出青海省不同地区适宜种植的小黑麦种质以及适合种植小黑麦的地区.[方法]采用甘农4 号、甘农2 号、品系C25(简称C25)小黑麦种质为材料,比较青海省不同地区(同德县、湟中区、格尔木市)小黑麦生产性能和营养品质,筛选适合青海种植的小黑麦种质和地区.[结果](1)C25 的生产性能指标显著高于甘农4 号、甘农2 号;C25 的中性洗涤纤维含量(46.75%)最低,显著低于其他2 个小黑麦品种;甘农2 号的酸性洗涤纤维含量(32%)最低,C25 的酸性洗涤纤维含量(32.77%)次之,显著低于其他小黑麦种质.(2)同德县试验点小黑麦的生产性能指标(干草产量、株高和枝条数)显著高于其他2 个试验点;同德县试验点小黑麦的可溶性糖含量(9.41%)显著高于其他2 个试验点.(3)同德县C25 干草产量(11.19 t/hm2)最高,显著高于其他水平;湟中区甘农4 号可溶性糖含量(11.60%)最高,同德县C25 次之,显著高于其他水平;湟中区C25 中酸性洗涤纤维含量(41.67%)最低,显著低于其他水平.(4)同德县C25 排名第1,湟中区C25 排名第2 和同德县甘农4 号排名第3.[结论]同德县试验点适合种植的小黑麦种质为C25,甘农4 号次之;湟中区试验点适合种植的小黑麦材料为C25,甘农4 号次之;格尔木市试验点适合种植的小黑麦种质为C25,甘农 2号次之.3 个试验点中,同德县最适合种植小黑麦;3 个小黑麦种质中,小黑麦C25 最适合在青海种植.

摘 要：
[Objective]To screen the suitable triticale materials in different areas of Qinghai Province and the most suitable triticale areas in Qinghai.[Methods]Using Gannong No.4,Gannong No.2,and line C25 triticale germplasm as materials,through the comparison of production performance and nutritional quality in different areas of Qinghai Province(Tongde,Huangzhong,Geermu),thus concluding that suitable for Qing-hai Triticale germplasm and region of cultivation.[Results](1)The three triticale germplasms,the produc-tion performance index of C25 was significantly higher than that of Gannong No.4 and Gannong No.2;the neutral detergent fiber content of C25(46.75%)was the lowest,significantly lower than the other two triti-cale varieties;Gannon 2 had the lowest ADF content(32%),followed by C25(32.77%),significantly low-er than other triticales germplasm.(2)The production performance index(hay yield,plant height,number of branches)of triticale in Tongde experimental site was significantly higher than that in the other two experimen-tal sites;the soluble sugar content(9.41%)of triticale in Tongde experimental sitewas significantly higher than that in the other two experimental sites.(3)Tongde C25 had the highest hay yield(11.19 t/hm2),which was significantly higher than other levels;Huangzhong Gannong 4 had the highest soluble sugar content(11.60%),followed by Tongde C25,which was significantly higher than other levels;Huangzhong C25 had the lowest NDF content(41.67%),which was significantly lower than other levels.(4)Tongde C25 ranks first,Huangzhong C25 ranks second and Tongde Gannon 4 ranks third.[Conclusion]The triticale material suitable for planting at the Tongde test site is C25,followed by Gannon No.2;The triticale material suitable for plant-ing at the Huangzhong test site is C25,followed by Gannon No.4;The triticale material suitable for cultiva-tion at the Golmud test site is C25,followed by Gannon 2.Among the three test sites,Tongde is the most suit-ablefor growing triticale;Among the three triticale germplasm,triticale C25 is the most suitable for planting in Qinghai.
