| 摘 要： | 通过对引进的3个俄罗斯黄花苜蓿品种(达菲、秋柳和雅酷)与国内的锡盟野生黄花苜蓿形态进行的比较分析表明,锡盟黄花苜蓿呈半直立生长,适合驯化栽培利用;而3个引进品种匍匐生长,适合与其他牧草混播或放牧利用。达菲、秋柳和雅酷具有极强的分枝能力,生长至第二年分枝平均可达每株73.7、88.6和88.1个,并且根系特别发达,其中表层土壤侧根数量是锡盟黄花苜蓿的1.5～2倍,侧根生物量是锡盟黄花苜蓿的3～4倍。

| Abstract: | The morphological variation of three Medicago falcata L.cultivars-Darviluya,Syulinskaya and Yakuskayayellow introduced from Russian and one wild yellow-flowered alfalfa Ximeng from Inner Mongolia was compared.The results showed that: 1.Because of the character of semi-erect,Ximeng should be domesticated,while three cultivars should be used in mixture grassland or Grazing Pastures for the creep character.2.Both the branchs and the roots of Darviluya,Syulinskaya and Yakuskayayellow are excellent.In the second year,the branch number of Darviluya,Syulinskaya and Yakuskayayellow is 77.7,88.6 and 88.1/plant.The number of three cultivars lateral roots is 1.5~2 times more than Ximeng's,and the biomass is 3~4 times.3.the three cultivars can absorb the nutrient and water in relative shallow soil,but Ximeng can absorb the nutrient and water in relative deep soil. |
