摘　　要：在西部甘肃张掖典型沙化撂荒地,采用固沙保土有机肥与多年生抗旱固氮牧草植物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,选用具有抗旱固氮特性的"草原3号杂花小叶苜蓿"条播后,随即喷施"固沙保土有机肥",可初步形成牧草植被生态系统。This paper makes the field test on the typical abandoned desert land of Zhangye in Gansu Province by using the method of combining the sand-fixation and soil-protection organic fertilizer and the perennial drought-resistant and nitrogen-fixating pasture plants. The results show that on the semiarid desert land, spreading the sand-fixation and soil- protection organic fertilizer after the row planting by selecting the Grassland No.3 Clover with drought-resistant and nitrogen-fixing features can form preliminarily the pasture vegetation ecological system.
