| 摘 要： | 陇东野生紫花苜蓿Medicago sativa为根茎-平卧型多年生苜蓿,分布于甘肃清水、定西半阴湿山脚地带,经植物学、生物学特征特性观察,结果表明:陇东野生紫花苜蓿与栽培紫花苜蓿相比,其生长速度慢,叶片小且数量少,根系为根茎型,无主根,茎纤细且平卧或半平卧生长,分枝能力强,耐践踏,抗寒、抗旱,有许多栽培苜蓿所没有的植物学和生物学特征特性.

| Abstract: | Longdong wild alfalfa is a kind of rhizome-slantwise,perennial forage,which grows in the semi damp mountainous area in Dingxi and Qingshui county of Gansu province.The results of cultivation experiment showed that: compared with cultivated alfalfa,Longdong wild alfalfa had a slower growth rate and a stronger branching ability with smaller leaf size and less leaf numbers.Its roots were rhizome type and grew slant-wise or horizontally without main taproot.It was tolerant to trample and drought and had many other botanic and biological characteristics that cannot be found in cultivated alfalfa. |
