| 摘 要： | 在温室条件下,应用反复干旱法,连续干旱法和“电导”法,对10个优良牧草品(草)种进行了抗旱性与耐热性鉴定。试验结果表明:用3种方法测定的结果基木一致。以伊犁蒿、驼绒藜抗旱耐热性最强。4种禾草中以老芒麦、无芒雀麦抗旱耐热性较强,苇状羊茅居中,布顿大麦最弱。4个苜蓿品种中以阿勒泰杂花苜蓿、新牧1号杂花苜蓿抗旱耐热性最强,贝维尔杂花苜蓿次之,北疆苜蓿表现最弱。结论表明,今后对牧草抗旱耐热性鉴定可采取本文使用的两种以上方法对照测定。

| Abstract: | In the greenhouse conditions, the drought resistance and heat resistance of ten kinds of forage varieties were measured by means of the redrought method, continuousdrought method and electric-rate method in Urumchi city in 1988～1989. The restults were as follows, 1. the drought resistance and heat resistance of Seriphidium transillensis and Ceratoides latens were the best in ten forage varieties, those of Bei Jiang alfalfa were the worst; 2. in the four grasses, the drought resistance and heat resistance were Elymus sibiricus>Bromus inermis>Festuca arundinaceu>Hordeum bogdanii; 3. in the four alfalfas, the drought resistance and heat resistance were Aleitai alfalfa>Xin Nol alfalfa>Bei Weiai alfalfa>Bei Jiang alfalfa. |
