中文摘要	探讨了阿拉善干旱荒漠区强旱生植物霸王Zygophyllum xanthoxylum、红砂Reaumuria Soongorica地上部分可食嫩枝的有机养分如蛋白质、脂肪、纤维素、无氮浸出物和无机养分钙、磷、粗灰分含量的季节动态,以及各营养物质间的相关性.研究结果表明,生长前期纤维素含量较低,其余各养分含量均呈增加趋势,进入生长末期,各养分含量呈下降趋势,纤维素含量则达到最高值.在整个生育期,粗蛋白与粗纤维、粗纤维与粗灰分之间呈显著的负相关关系,粗蛋白与粗灰分、粗蛋白与磷、钙与粗灰分之间均呈显著的正相关关系.
英文摘要	A study was carried out on the seasonal change in content as well as relationships between organic nutrients such as protein, fat, cellulose, and nitrogen-free extract, and inorganic nutrients including Ca, P, and ash in the aboveground edible spray of the strong xerophils Zygophyllum xanthoxylum and Reaumuria Soorgorica in the Alashan desert area. In the early stage of growth, the cellulose content was relatively low, and the content of other nutrients all showed increasing trends. In entering the last growth stage, the differ-ent nutrient contents showed decreasing trends, but the cellulose content reached its highest value. For the entire growth and development period, there were significant negative correlations between crude protein and crude fibre, and between crude fibre and crude ash, and significant positive correlations between crude protein and crude ash, crude protein and P, and Ca and crude ash.
