优良豆科牧草引种对比试验研究

摘要

本文通过在新疆塔城市灌溉条件下,2007-2009连续三年对阿尔冈金苜蓿、和田苜蓿、红豆草、小冠花和百脉根5种豆科牧草的生产性能进行了观测研究。结果表明,各牧草一般于4月份返青,7月中旬至8月初种子成熟,生育天数110～150d。最后一次刈割后再生草大部分于10月枯黄,生长天数150～180d。干草产量排序为：阿尔冈金苜蓿〉小冠花〉和田苜蓿〉红豆草〉百脉根;茎叶比资料显示,叶量所占比例分别为阿尔刚金苜蓿41.3%、小冠花44.8%、和田苜蓿48.5%、红豆草58.3%、百脉根52.9%,各种牧草表现出了不同的生态适应性。%Under the condition of irrigation in TaCheng,the production performance of five leguminous forages such as Argangjin alfalfa,Hetian alfalfa,sainfoin,coronilla varia and lotus japonicas were observed during the three years from 2007 to 2009.The result shows that the forage turns green in April in general and the seed grow to maturation from mid July to early August.The whole growth period is 110～150d.What＇s more,the aftermath turns yellow in October after the final cutting and the whole growth period is 150～180d.The yield of the dry forage is arranged,which is Argangjin alfalfa coronilla varia Hetian alfalfa sainfoin lotus japonicus.According to the data of stem and leaf ratio,the proportion of leaf quantity is that 41.3%（Argangjin alfalfa）,44.8%（coronilla varia）,8.5%（Hetian alfalfa）,58.3%（sainfoin）,52.9%（lotus japonicas）.Each herbage showed different ecological adaptability.
