本试验连续四年研究了北京地区在依靠自然降水的条件下，沙打旺在沙荒地上的生长情况。结果表明，沙打旺长势良好，每年可产干草11250kg·hm-2。在沙打旺生长期间，迟干旱年份时，土壤水分状况0～40cm土层为干上层．0～200cm土层的土壤重量含水量低达3％；在雨季期间．土壤的水分状况得以恢复。土壤的肥力状况表现为全氮、全磷、碱解氮、速效磷以及土壤有机质含量都有减少；仅速效钾含量增加。本试验还研究了沙打旺抗旱的生物学特性，如沙打旺根系在不同土层中的分布特点、根毛与细土粒之间的紧密结合、沙打旺以基都叶脱落的方式来减少蒸腾躲避干旱等等。本试验为北京地区沙荒地的利用以及沙打旺的种植提供了参考的依据。
This experiment for four consecutive years studied the Beijing area under the conditions of relying on natural precipitation, sand Wang Wang in the desert growth conditions. The results show that the sand prosperous prosperous good annual output of hay 11250kg · hm-2. During the growing period of Astragalus mongholicus and in later dry years, the soil layer of 0-40 cm soil moisture condition is the dry upper layer. Soil moisture in 0-200 cm soil layer is as low as 3% of water content; during the rainy season. Soil water conditions have been restored. Soil fertility conditions showed total nitrogen, total phosphorus, available nitrogen, available phosphorus and soil organic matter content has decreased; only available potassium content increased. The study also studied the biological characteristics of Astragalus adsurgens drought resistance, such as the sand Wangwang in different soil layers in the distribution characteristics, root hair and fine soil between the close combination of sand Astragalus to base leaves off Reduce transpiration and avoid drought. This experiment provides a reference for the utilization of deserted shrubs and planting of Astragalus adsurgens in Beijing.
