利用主成分分析，结合模糊聚类的方法进行谷子的抗旱性综合评价，不仅可以避免单一指标的片面性和不稳定性，而且可以较好地揭示谷子抗旱相关性状与其抗旱性的关系。

The results showed that "Green Drought Resistance agent NO.1, NO.2 and NO.3" harmonized ear number, spike number and 1000-seed weight of winter wheat in dry land, they have good yield-improving effects. The drought-enduring experimentation showed that with the raising of the PEG density, the restrain that burgeon and rootage got on each treatment were more obvious. The drought resist of burgeon ratio, length of bud, rootage ratio, number of root and length of root treated by GDR1 was better than check's.

结果表明：GDR1号、GDR2号和GDR3号抗旱剂较好地协调了旱地冬小麦的穗数、穗粒数、千粒重，具有较好的产量效应；耐旱性试验表明，随着PEG浓度的增高，各处理发芽和生根受到抑制作用越明显，GDR1号处理的发芽率、芽长、生根率、根数和根长的抗旱性优于对照；不同土壤水分条件下绿色抗旱剂GDR1号的出苗率、幼苗和根系生长与不同PEG浓度条件下的处理结果相一致。

There were so huge roots and rhizome system under ground that they could absorb water from deep soil; Stems and leaves on ground could decrease water loss. The huge biomes of G.uralensis had strong drought resistance superiority. In the same time, drought stress significantly restrained the growth of G.uralensis. On the contrary, in some extent, drought stress could improve the growth of roots under ground and resulted in increasing the rate of root/shoot; moreover, made the color of velamen become red and enhanced the output and the quality.

主要结论如下：(1)在形态与生长反应方面，观察发现甘草地下和地上两部分都具有适应干早环境的特征，地下有庞大的根和根茎系统，吸水能力很强，地上茎叶形态表现出很强的节水能力，并且甘草群体抗旱优势很强；同时也观测到干旱对甘草地上茎叶生长抑制较为明显，但在一定程度上对地下根系生长起到了促进作用，导致根冠比增大、根皮颜色变红，即在产量和质量方面都有了很大地提高。

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、沙生冰草、蓝茎冰草、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。

In this paper, Cerasus humilises in Huangshandian was used to investigate effects of NaHCO3 and drought stress. Several physiological during the trgatment with NaHCO3, drought as well as NaHCO3/drought combination for 25 days.
