[目的]了解4种进口紫花苜蓿的抗逆性特点,为其在不同区域内种植提供基础性数据。[方法]对从国外引进的4个苜蓿品种进行抗胁迫比较试验,通过分析其出苗情况来了解它们的抗胁迫特点。[结果]4种紫花苜蓿的耐酸能力为:金皇后>飞马>阿尔冈金>维多利亚;4种紫花苜蓿的耐碱能力为:飞马>阿尔冈金>金皇后>维多利亚;4种紫花苜蓿的耐盐能力为:飞马>金皇后>阿尔冈金>维多利亚;4种紫花苜蓿的耐盐碱能力为:飞马=阿尔冈金>金皇后>维多利亚。[结论]应根据4种紫花苜蓿的抗逆特点,分别选择合适的土壤种植。
[Objective] The research aimed to understand the stress tolerance of four kinds of imported alfalfa and provide basic data for planting in different regions. [Method] The four alfalfa varieties introduced from abroad were tested for their anti-stress effects and their anti-stress characteristics were analyzed by analyzing their emergence. [Result] The acid resistance of four alfalfa varieties was: Golden Queen> Pegasus> Algonquin> Victoria. The alkali tolerance of the four alfalfa varieties was Pegasus> Algonquin> Golden Queen> Victoria. Four species of alfalfa The salt tolerance of four species of alfalfa was: Pegasus = Algonquin> Golden Queen> Victoria. [Conclusion] According to the resistance characteristics of four kinds of alfalfa, the suitable planting of soil should be selected respectively.
