This shows that the DPR of Atriplex canescens is reducing with the escalationof soil water stress, and its physiological activities obviously became weak.

说明四翅滨藜随土壤水分胁迫的加重，其DRR出现明显的下降趋势，生理活动明显减弱。

The growth of radical and hypocotyls time of seed was delayed by long time natural store and refrigeration, and the condition of long time natural store for Atriplex canescens seed's vigor was the worst.

长时间自然存放和冷藏均会推迟四翅滨藜种子胚根和胚轴的延伸日期，且长时间自然存放推迟的更晚。得出长时间自然存放使种子的活力降低最快。

National Forestry Corporation to policy-oriented and give full play to the advantages of private enterprises, and take the road of combination, the introduction of new varieties Poplar, gold-banded fast-growing grass, Atriplex canescens and other high-tech eco-products, and a large area throughout the country Promotion, a high starting point, high standard construction of fast growing high-yielding forest and pasture resources base, to the development of an investment recovery period is short, quick, significant benefits of the green industry, thus promoting regional economic development.

公司以国家林业政策为导向，充分发挥民营企业的优势，走强强联合之路，引进了新品种速生杨、天香速生牧草、四翅滨藜等高科技生态产品，并在全国范围内进行大面积推广，高起点、高标准建设速生丰产林及高产牧草资源基地，力求发展一个投资回收期短、见效快、效益显著的绿色产业项目，从而促进地区经济发展。

An experiment was conducted to study the cold and alkali resistances of Atriplex canescen from Colorado, Wyoming, Utah, and California provenances, and superior provenance was selected in terms of cold resistance indexes.

对科罗拉多州、怀俄明州、尤他州和加利福尼亚州4个不同种源的四翅滨藜进行了耐碱性、耐寒性试验以及优势种源的选择。

Atriplex canescens is an evergreen shrub introduced from the United States. Trials onits ecophysiological and drought-resistance features were conducted.

从美国引进的准常绿灌木(2年生实生苗)—四翅滨藜在民勤干旱沙区进行抗旱生理生态试验。

The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done

从干旱沙区民勤治沙综合试验站的栽培来看，四翅滨藜在此地表现出了耐旱、耐寒、耐盐碱、耐低温且年生长量大的优良特性，因此可以在有灌溉条件的沙区和降雨较多且蒸发较小的黄土丘陵区进行推广，作为该地区的水土保持和草场更新的新物种，具有一定的推广潜力，但推广地域范围的划分，仍需进一步的试验研究和充分的科学论证。

Two-year old plants of Atriplex canescens Nutt introduced from the west of America were planted at China flowerpots under the different moisture contents at soil in pot. Plant growth and biomass distribution characteristics were researched.

从美国西部引进2年生准常绿灌木四翅滨藜分别定植于含水量不同的陶瓷花盆土壤中，通过人工控制土壤水分研究其生长和生物量的分配特性。

In August,there are obvious changes among different treatments under soil water stressconditions. Vs, and Vs/Va obviously raised while Va reduced, and tissue water contentalso changed. Comparing with that in July, water content of leaves in differenttreatments in August decreased by 18.06%, 2.57%, 4.82% and 9.94%, respectively.In August and September, diurnal average Tr under different treatments (light,medium, heavy and no soil water stress conditions ) are 80.90 mmolh_2Om~(-2)s~(-1)、76.37mmolh_2Om~(-2)s~(-1)、65.46 mmolh_2Om~(-2)s~(-1)、42.11 mmolh_2Om~(-2)s~(-1) and 40.60mmolh_2Om~(-2)s~(-1)、33.92 mmolh_2Om~(-2)s~(-1)、30.44 mmolh_2Om~(-2)s~(-1)、23.29 mmolh_2Om~(-2)s~(-1),respectively. It shows that the Tr of Atriplex canescens leaves takes a tendency ofdeclining under long-term soil water stress conditions.

随着土壤水分胁迫时间延长到8月份，各处理间相比发生了显著变化，其中Vs、Vs／Va显著升高，Va的降低，而组织含水量也发生了显著的变化；8月份各处理间(无土壤水分胁迫、轻度土壤水分胁迫、中度土壤水分胁迫和重度水分胁迫)与7月份相比叶片含水量分别降低了18.06％、2.57％、4.82％、9.94％；在8月份和9月份轻度土壤水分胁迫、中度土壤水分胁迫、重度土壤水分胁迫和无土壤水分胁迫的Tr的日均值分别为80.90 molh_2Om~(-2)s~(-1)、76.37mmolh_2Om~(-2)s~(-1)、65.46 mmolh_2Om~(-2)s~(-1)、42.11 mmolh_2Om~(-2)s~(-1)和40.60 molh_2Om~(-2)s~(-1)、33.92 mmolh_2Om~(-2)s~(-1)、30.44 mmolh_2Om~(-2)s~(-1)、23.29 mmolh_2Om~(-2)s~(-1)，说明四翅滨藜在长期的土壤水分胁迫胁迫下叶片的蒸腾速率呈现出下降的趋势。

Under soil water stress, the biomass of Atriplex canescens reduced, ratio betweenroot and stem increased, the main root becomes long, branches and lateral rootsreduced, and its growth is restrained.

土壤水分胁迫下四翅滨藜的生物量显著降低，根茎比增加，主根伸长，分枝数和侧根数明显减少，生长发育受到抑制。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
