摘　　要：为探索半干旱沙化荒漠地区牧草生态系统重建与保持技术，在甘肃省张掖典型沙化撂荒地，采用固沙保土有机肥与草原3号杂花苜蓿相结合的方法进行野外试验。结果表明：在半干旱沙化荒漠地，草原3号杂花苜蓿（Medicago varia cv．caoyuan No．3）条播后，随即喷施50～60倍的具有黏结、吸湿、保水功能的“固沙保土有机肥”溶液90～120t／hm2，同时完成浇水、施肥、铺膜（自然形成的可降解生态地膜）3道工序，基本满足草原3号杂花苜蓿发芽生长所需的水分和养分，从而初步形成牧草生态系统。This paper aims maintain the reconstruction and to explore the semi-arid sandy desert vegetation forage production systems to model of new technologies. Zhangye in Gansu Province in the western desert of abandonment to the typical use of sand and organic fertilizer and soil nitrogen--fixing perennial pasture plant drought combination of field tests. The results showed that. in the semi-arid sandy desert, the choice of having the above-mentioned characteristics of the ＂Prairie flower miscellaneous 3 lobular Alfalfa＂drilling after spraying 50 to 60 times with adhesive, moisture,water features ＂organic fertilizer and soil-fixing＂ solution of 90~120t / ha,while the completion of watering, fertilization, Filming （naturally occurring biodegradable eco-plastic）3 process,basic to meet the growth of forage plants germination moisture and nutrients required in order to shape pasture vegetation ecosystems.
