‘甘农2号’黑麦品种在青海省不同区域的适应性评价

Adaptability Evaluation of Secale cereale ‘Gannong No.2 ’ in DifferentRegions of Qinghai Province

本试验以‘甘农2号’黑麦(Secale cereale L.)为试验材料,以‘冬牧70’和‘黑饲麦’为对照,来评价‘甘农2号’在2018-2019年在青海省不同区域(海晏县、湟中县、平安区)的适应性。结果表明:3个黑麦品种中,‘甘农2号’在3个试验点的平均干草产量(13.04 t·hm-2)显著高于‘冬牧70’和‘黑饲麦’,平均纤维含量显著低于‘冬牧70’和‘黑饲麦’;3个试验点中,海晏点3个黑麦品种的平均干草产量(12.06 t·hm-2)显著高于湟中和平安点;品种×年份交互作用中,2018年‘甘农2号’黑麦的平均干草产量(14.38 t·hm-2)显著高于其他处理;试验点×年份交互作用中,2018年海晏点3个黑麦品种的平均干草产量(14.47 t·hm-2)显著高于其他处理。综上所述,‘甘农2号’黑麦干草产量和营养品质高且较稳定,适应青海省海晏县、湟中县和平安区以及其他气候相似区种植。

In this study,Secale cereale L.‘Gannong No.2’was used as the experimental material,and‘Dongmu 70’and‘Black feeding rye’were used as controls to evaluate the adaptability of‘Gannong No.2’in 2018-2019 in different regions of Qinghai Province(Haiyan,Huangzhong,Ping'an).The results showed that,from a single factor point of view,the averaged hay yield(13.04 t·hm-2)of‘Gannong No.2’were significantly higher than the 2 controls at 3 experimental sites,the average content of fiber was significantly lower than the 2 controls;among 3 experimental sites,the average hay yield(12.06 t·hm-2)of 3 rye varieties in Haiyan was significantly higher than that of Huangzhong and Ping'an.For 2 factors,the average hay yield of‘Gannong No.2’(14.38 t·hm-2)in 2018 was significantly higher than other treatments when consider the interaction of varieties and years;for the interaction of experimental sites and years,average hay yield of 3 rye varieties at Haiyan in 2018(14.47 t·hm-2)was significantly higher than that of other treatments.In conclusion,‘Gannong No.2’had the highest hay yield and best nutritional quality among the 3 varieties,and is suitable to be cultivated in Haiyan,Huangzhong,and Ping'an districts of Qinghai province and other regions with similar climate.
