As a result, synthesizing the comparison of the characteristics of drought resistance, cold tolerance, barren resistance and production of these ten grasses, we have found that the resistance of Bromus inermis,Festuca arundinacea was better , and consequently Bromus inermis , Festuca arundinacea were proofed to be favorable grasses for developing pasture in northern China in the future. Whereas, Bromus biebersteinii, Festuca rubra,Dactylis glomerata,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea were worse, and therefore measures to local conditions and prudence in the production practice were advocated.

因此,综合抗旱性、耐寒性、耐贫瘠性及田间的生产性能的比较研究,10种牧草中的无芒雀麦、苇状羊茅的抗性表现较好,是今后我国北方地区进行人工草地建设的良好牧草种类;而草地雀麦、紫羊茅、沙生草、蓝茎草、长穗偃麦草、猫尾草、鸭茅和草芦表现不好,在生产实践中应因地制宜、谨慎推广。

In the aspect of grass cold tolerance, these ten grasses were classified into three types by the cluster analysis, based on winter survival adaptability and LT50 measured under low temperature treatment. High cold tolerance: Bromus biebersteinii,Bromus inermis,Festuca arundinacea, Agropyron desertorum,Elytrigia elongate, Phleum pretense; medium cold tolerance: Festuca rubra, Agropyron smithii,Dactylis glomerata; low cold tolerance: Phalaris arundinacea.

禾本科牧草在耐寒性方面,根据牧草越冬适应性表现和低温处理下用电导法得出的半致死温度, 10种牧草进行聚类分析结果表明:耐寒性强的是草地雀麦、无芒雀麦、苇状羊茅、沙生草、长穗偃麦草、猫尾草;耐寒性中等的是紫羊茅、蓝茎草、鸭茅;耐贫瘠性最弱的是草芦。

By the cluster analysis, 10 grasses were classified into three types—of high barren resistance: Bromus inermis,Festuca arundinacea, Dactylis glomerata; of medium barren resistance: Bromus biebersteinii,Phleum pratense,Phalaris arundinacea; of low barren resistance: Festuca rubra, Agropyron desertorum,Agropyron smithii,Elytrigia elongate.

对10种牧草进行聚类分析,得出耐贫瘠性强的是无芒雀麦、苇状羊茅、鸭茅;耐贫瘠性中等的是草地雀麦、猫尾草、草芦;耐贫瘠性最弱的是紫羊茅、沙生草、蓝茎草、长穗偃麦草。

In order to select a kind of eminent grass which is adaptable to the northern China, the present thesis studies ten kinds of grasses from Gramineae, Bromus biebersteinii,Bromus inermis,Festuca arundinacea ,Festuca rubra,Dactylis glomerata ,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea,and also explores the physiological aspects of their drought resistance, cold tolerance and barren resistance. The drought resistance experiment was conducted to study 10 grasses under water stress during seedling stage by simulating indoor drought environment.

为了能选适应我国北方地区的抗旱、耐寒、耐贫瘠特性的优良牧草,本研究以草地雀麦、无芒雀麦、苇状羊茅、紫羊茅、沙生草、蓝茎草、长穗偃麦草、猫尾草、鸭茅、草芦为材料,在抗旱、耐寒和耐贫瘠性特性三方面的生理方面进行了探索研究。
