14个多年生牧草品种在川西北高寒牧区适应性研究
|
摘要
采用田间小区方法,以2014~2017年在四川省甘孜州道孚县乾宁种畜场对早熟禾(Poa pratensis)、多年生黑麦草(Lolium perenne)、雀麦(Bromus inermis)、猫尾草(Phleum pratense)、细茎冰草(Agropyron trachycaulum)、扁穗冰草(Agropyron cristatum)和紫花苜蓿(Medicago sativa)共14个品种同期播种,连续4年进行田间观察和产草量测定。结果表明:在川西北地区种植的14个牧草品种细茎冰草因越冬率低,不适应当地环境,在2016年低全部死亡,其余13个草品种都可安全越冬,正常生长,但不同品种产草量差异显著或极显著。从产量总趋势分析,诺言猫尾草、乌苏1号无芒雀麦、热销多年生黑麦草、新速Ⅱ多年生黑麦草、三得利紫花苜蓿等5个品种产量较高,值得在本区生产上应用推广。
The adaptability of 14 perennial grasses including 2 Kentucky bluegrasses(Poa pratensis),3 perennial ryegrasses(Lolium perenne),4 smooth bromegrasses(Bromus inermis),1 timothy grass(Phleum pratense),1 slender wheatgrass(Agropyron trachycaulum),1 crested wheatgrass(Agropyron cristatum)and 2 alfalfaes(Medicago sativa)was studied by using field plot test from 2014 to 2017 in Daofu County,Ganzi Prefecture of Sichuan Province.The results showed that the wintering rate of slender wheatgrass was 0%,the rest of tested grasses could overwinter,but the yield variation was significantly great.In general,Promise timothy,Wusu No.1 smooth bromegrass,Caliente perennial ryegrass,NewspeedⅡ perennial ryegrass,Sanditi alfalfa had high yield and quality.
