Under the different sowing seeds way the soil ulmin, the alkaline hydrolysis nitrogen, the fast-acting phosphorus content present the tendency which in 0-40cm various soil layers increases along with the soil layer depth reduces, take 0-10cm soil layer soil content as biggest; The change tendency which the colleague mixes broadcasts mixes with the interlacing broadcasts the change tendency which the lawn fast-acting potassium presents reduces, after the unicast awnless brome lawn presents falls first, increases again falls, take 0-10cm and 20-30cm soil layer soil content as biggest, is 80, and achieves the extremely remarkable difference with other soil layers between; pH presents increases the tendency.

混播草地上牧草根系死亡后，能在土壤中遗留大量的有机质，在土壤微生物的作用下形成土壤腐殖质，其中有丰富的氮、磷、钾等元素。无芒雀麦，又名禾萱草，无芒草，是世界上分布较广，应用较多的优良牧草；是草地补播和建立人工草地的理想草种。无芒雀麦生长快，竞争力强，在杂草较多的草荒地上种植，也能获得成功，为我国温带和寒温带建造人工草地的当家草种。

In the test 5 treatments of single-sowed alfalfa or smooth brome grass, and their mix-sowing with different ratios of 50%+50%, 60%+40% and 70%+30% were set up to analyze pH, CP, NDF, ADF, acetic acid, butyric acid, lactic acid and total acid of the silage in each treatment and study the effect of alfalfa and smooth brome grass with different mix- sowing ratio on silage quality.

方法］试验设5个处理，即紫花苜蓿单播、无芒雀麦单播、紫花苜蓿＋无芒雀麦以50%+50%、60%+40%和70%+30%比例混播，分析各处理青贮材料的pH值、CP、NDF、ADF、乙酸、丁酸、乳酸和总酸的变化，研究无芒雀麦与紫花苜蓿不同比例混播对青贮品质的影响。

In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

引进美国无芒雀麦是农业部948项目&旱生灌草植物资源的引进及开发利用&的引进草种之一，为了合理开发和利用它，本论文对引进无芒雀麦和本地无芒雀麦的种子萌发、田间种植和栽培技术3个方面进行了对比研究，比较了两种无芒雀麦生长特性；结合方差分析，确定了引进美国无芒雀麦种子萌发指标和栽培技术指标。
