摘　　要：本试验以‘甘农4号’小黑麦(×Triticale Wittmack)品种为试验材料,‘石大1号’(CK1)和‘中饲1048’(CK2)为对照,通过研究在青海省不同区域(海晏、湟中、平安)的干草产量和营养价值,以评价其适应性。结果表明:从单因素看,‘甘农4号’在3个试验点的平均干草产量(14.07 t·hm^-2)显著高于CK1和CK2;海晏点3个小黑麦品种的平均CP含量(10.54%)显著高于湟中和平安点;2018年3个小黑麦品种的平均干草产量(12.98 t·hm^-2)显著高于2019年(9.23 t·hm^-2)。2因素间,品种×试验点交互作用中,‘甘农4号’在海晏试验点的平均CP含量(11.08%)显著高于其他处理;品种×年份交互作用中,2018年‘甘农4号’小黑麦的平均干草产量(16.26 t·hm^-2)显著高于其他处理;试验点×年份交互作用中,平安点2018年3个小黑麦品种的平均干草产量(15.20 t·hm^-2)显著高于其他处理。3因素交互作用中,2018年平安点‘甘农4号’小黑麦的干草产量(20.45 t·hm^-2)显著高于其他处理。综合评价表明,‘甘农4号’小黑麦更适宜于在青海省低海拔且水热条件丰富的地方推广种植,这是获得小黑麦高产优质饲草的首要条件。In this experiment,Triticosecale Wittmack‘Gannong No.4’was used as the experimental material,triticale varieties‘Shida No.1’(CK1)and‘Zhongsi 1048’(CK2)were used as controls,by studying its hay yield and nutritional value in different regions of Qinghai Province(Haiyan,Huangzhong,Ping'an),the adaptability was evaluated.Results showed that,the average hay yield(14.07 t·hm^-2)of‘Gannong No.4’at the 3 experimental sites was significantly higher than that of CK1 and CK2;the average CP content of the 3 triticale varieties in Haiyan(10.54%)was significantly higher than Huangzhong and Ping'an;the average hay yield of the 3 triticale varieties in 2018(12.98 t·hm^-2)was significantly higher than that in 2019(9.23 t·hm^-2).For the interaction of 2 factors,the averaged CP content(11.08%)of‘Gannong No.4’at Haiyan experimental site was significantly higher than the other treatments for the interaction of varieties and experimental sites;The averaged hay yield(16.26 t·hm^-2)of‘Gannong No.4’in 2018 was significantly higher than the other treatments for the interaction of variety and year;And the averaged hay yield(15.20 t·hm^-2)of 3 triticale varieties at the Ping'an experimental site in 2018 was significantly higher than the other treatments for the interaction of experimental sites and years.In the interaction of the 3 factors,the hay yield(20.45 t·hm^-2)of triticale in Ping'an site‘Gannong No.4’in 2018 was significantly higher than other treatments.Comprehensive evaluation showed that‘Gannong No.4’triticale is more suitable to be planted in places with low altitude and rich water and heat conditions in Qinghai Province.This is the first condition for obtaining high-yield and high-quality triticale forage.
