On the basis of clean cultivated Pasture of Perennial Lucerne and mixture pasture of perennial awnless brome and Lucerne, the effect of Pasture species and mixing method on Pasture drying rate was analyzed.

用多年生的紫花苜蓿单播草地牧草和多年生无芒雀麦与紫花苜蓿的混播草地牧草，研究牧草种类及调制方法对牧草干燥速度的影响。

The results indicated that the seed vigor of Brudzynska, Bezenchukii Bromus inermis is lower under the level of 5%, but it is high under the level of 10%-20%.

在5%PEG的干旱胁迫下，Brudzynska、Bezenchukii无芒雀麦的种子活力较低，但在10%~20%PEG的干旱胁迫下，两者的种子活力较高，而内蒙古正镶蓝旗野生沙地雀麦和内蒙古克什克腾旗野生沙地雀麦种子活力较低。

In this paper, we studied community stability, forage quality and yield character about the mixed-sowing of Medicago sativa and Bromus intermis from 2003 to 2004 and using Factor Analysis, Principal Components Analysis methods and getting the yield forecast model with linear regress multianalysis method. The study provided theoretical foundation for establishing high yield and good quality artifical pasture.

本试验以紫花苜蓿与无芒雀麦为供试材料，于 2003~2004 年对 6 个不同混播处理的群落稳定性、牧草产量及质量性状进行了系统的研究，并运用因子分析法、主成分分析法和多元线性回归的方法，建立了产量预测预报模型，结合经济效益评价和提高土壤肥力的因素，确立最佳混播处理。

Every treatment combination has 4 replications.(1)The germination indexes of the former are higher than that of the latter; the germination of the former is stimulated by NaCl density of 0.3 %, while that of the later is restrained by all kinds of NaCl density.(2)With increasing of temperature and PEG indesity,the order of germination rate and vigor of Bromus stamineus and Bromus inermis is decreaced.(3)Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), Bromus stamineus has the highest bud rate, fresh weight, seed yield, while treated with 25cm row spacing and 412kermels·m~(-2) plant densities, tillers, plant height, growth rate increased to the top;(4) Under treatment of broadcast sowing and plant density of 549kermels·m~(-2), its growth rate is took second place, while treated with 15cm row spacing and 824kermels·m~(-2) plant densities, it has the highest seed yield

3撒播时，引进种在播种密度为549粒·m~(-2)处理下单位面积出苗率最高，分蘖数最多，鲜重最大，单株最高，种子产量最大；生长速度在播种密度为412粒·m~(-2)处理下生长最快，密度为549粒·m~(-2)处理下稍次之，结合方差分析可以初步确定它在撒播时的播种密度为549粒·m~(-2)；(4)条播时，在行距为25cm、播种密度为412粒·m~(-2)处理下单位面积分蘖数最多，鲜重最大，单株最高，生长速度最快；种子产量在行距为15cm、播种密度为824粒·m~(-2)处理下最大，在行距为25cm、密度412粒·m~(-2)处理下次之；结合方差分析，就3种规格的行距来说，引进美国无芒雀麦条播时的行距为25cm，播种密度为412粒·m~(-2)；就这两种播种方式来说，应该选择撒播。

Transpiration rate、transpiration quantity and ground evaporation quantity of plants and leaves of Avena Sativa, Pisum Sativum, Bromus Innermis, Medicago Sativa are measured by using improved QCWC (quick and continuous weighting after being cut off method) in July, August and September.

采用改进的离体连续快速称重法对7~9月燕麦、豌豆、无芒雀麦(Bromus、Innermis)、紫花苜蓿枝和叶片的蒸腾速率、蒸腾量及土面蒸发量进行了测定。

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、沙生冰草、蓝茎冰草、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。

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、沙生冰草、蓝茎冰草、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。

On the leaving farmland, by surviving the seedling out rate, the feeding grass surviving rate, reviving rate, growth speed, tillering numbers, cluster measurement, degree of cover, root measurement, root Weight, fresh grass yield and hay yield, and so on, four kinds of feeding grasses which were Medicago sativa L., Dactylis glomerata L., Cichorium intybus L., Astragalus adsurgens Pall., were confirmed that can adapt the native ecosystem term and acquire good economic benefits in that year ; Bromus inermis Leyss. growed slowly in the first year, but Behaved well in the next year; Silpniumperfoliatum L.

弃耕地上通过对牧草出苗率、存活率、来年返青率、株高、分枝分蘖数、丛幅、根幅、根量、鲜草产量及干鲜比等的量测，确定苜蓿王、沙打旺、菊苣、鸭茅这四种牧草能适宜当地生态条件并于当年获得好的产量；无芒雀麦第一年生长较慢，但第二年表现良好；串叶松香目前为止表现不佳，能否引进成功有待观察。
