Abstract: The nutrition of Astragalus adsurgens, Hedysarum laeve, Astragalus melilotoides, Lespedeza davurica and Artemisia desertorum were measured. The nutrition of the five species of sandy plants showed obvious seasonal dynamic changes. As the growing season progressed, crude protein, crude fat and phosphorus content in the leaves and stems gradually declined, whereas ADF, NDF, and calcium content increased. Nitrogen free extract content at the beginning of July was higher than at other times, e.g. it reached 53.5% (P＜0.05) in leaves of A. adsurgens. At the beginning of August, fibre showed an upward trend, e.g. NDF and ADF contents of A. adsurgens and H. laeve reached 55.3% and 50.5%, respectively, a significant (P＜0.05) increase. Therefore, to obtain high-quality forage, the best harvest time would be from the end of June to the middle of July. Although crude protein content in leaves of A. desertorum was low, crude fat and calcium content were relatively high, 3.3% and 4.1% (P＜0.05) respectively. High-quality forage can be produced with timely mowing and processing modulation.
