摘　　要：为了探究青海省不同海拔生态区3种饲用小黑麦在不同播种时间下的生产性能,本试验设3个不同海拔生态区(乐都生态区,2016 m;湟中生态区,2630 m;同德生态区,3251 m),3个播种时间(早播,适播,晚播)和3个自育品系(ZHS2,ZHSI,GY197),测定和分析3个生态区的3个品系小黑麦在不同播种时间后的生育期、群体动态、草产量、穗部性状、籽粒产量和经济系数等指标的差异。结果表明,ZHS2在乐都生态区,3月5日播种综合生产性能最好;ZHS2在湟中生态区,4月10日播种综合生产性能最好;GY197在同德生态区,4月25日播种综合生产性能最好。本研究结果可作为青海农牧交错区高效种植小黑麦研究提供理论依据。In order to explore the production performance of three kinds of Forage Triticale under different sowing time in different altitude ecological regions of Qinghai Province,three ecological regions(Ledu ecological region,2016 m;Huangzhong ecological region,2630 m;Tongde ecological region,3251 m),three sowing time(early sowing,suitable sowing,late sowing),and three lines(ZHS2,ZHSI,GY197)were set up in this experiment.The growth period,population dynamics,grass yield,ear traits,grain yield and economic coefficient of three Triticale lines in three ecological regions at different sowing time were mearsured and analyzed.The results showed that,ZHS2 had the best comprehensive benefit on March 5 th in Ledu ecological region;ZHS2 had the best comprehensive benefit on April 10 th in Huangzhong ecological region;GY197 had the best comprehensive benefit on April 25 th in Tongde ecological region.The results of this study can provide theoretical basis for the study of efficient cultivation of Triticale in the farming pastoral ecotone of Qinghai Province.
