| 1 | Characteristics of ^(137)Cs deposition in steppe area显示文摘Soil wind erosion in the semiarid steppe area was studied using the 137Cs tracing technique. Comparisons of 137Cs deposition characteristics between different soil profiles indicated that slight aeolian activities occurred on sandy grasslands and semi-fixed dunes with erosion/deposition rates of less than 0.108 cm/a, whereas they were intense on semi-shifting dunes with erosion/deposition rates of higher than 1.35 cm/a. | ZHANG Chunlai, ZOU Xueyong,DONG Guangrong, ZHANG Xinbao & QIN ZhiLaboratory of Blown Sand Physics and Engineering, Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences, Lanzhou 730000, China China Center of D | 2002 | Chinese Science Bulletin2002，47，10： | 5 |
| 2 | Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature. | D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) | 1997 | 畜牧与饲料科学1997，22，S1： | 3 |

| 12 | Some Aspects of Macromineral Nutrition of Grazing Sheep in Northern China显示文摘A study was undertaken to evaluate the macromineral nutritional status of the grazing sheep at the three farms in northern China. On each farm 140, 2 or 3 -year - old reproducing ewes were used. The results obtained showed that Potassium, Magnesium and Phosphorus in the pasture were all lowest in winter and early spring. However, the ewes were given some grain - based supplements. hay and silage during this period. Of these supplements, concentrates contained high levels of phosphorus, and both hay and silage contained high levels of potassium, so that, severe deficiency of these elements during winter or spring was not likely- The results also found that summer and autumn may be when sheep were at most rise of a macromineral deficiency. Although pasture was plentiful and both protein and digestible energy were higher than other seasons of the year, sodium, in both summer and autumn, and phosphorus in autumn, were below published requirements.So, supplementation of both the elements during summer and autumn seasons are so important to improving growth and wool production as well as reproduction of the grazing ewes. | D X Lu,(Inner Mongolia Academy of Science.Hohhot City,Inner Mongolia Autonomous Region,PRC)S X Yut,(Institute of Animal Science,Chinese Academy of Agricultural Science,Malianwa,Haidianqu,Beijing,PRC)R Z Yang,(Xinjiang Institute of Animal Science,Xinjiang Academy of Animal Science.Yiu Hou Rd,Urumqi,Xinjiang Uygur Autonomous Region,PRC)K Shao(Inner Mongolia Academy of Science.Hohhot City,Inner Mongolia Autonomous Region,PRC)D G Masters(CSIRO Division of Animal Production.Private Bag,P.O.Wembley,Western Australia 6014) | 1997 | 畜牧与饲料科学1997，22，S1： | 0 |
