摘　　要：以青藏高原山地草原类草场为研究对象,通过对草地进行液体复合肥-绿迪乐喷施,分析施肥对天然草地牧草产量及高度的影响。结果表明:喷施液体复合肥-绿迪乐可大幅度提高牧草产量和群落高度。从生产角度考虑,结合不同喷施量处理效益对比分析,山地草原类草场进行液体复合肥-绿迪乐喷施时,喷施量为300kg/hm2比较经济合理。Based on mountain pastureland in Qinghai -Tibet pleatau as experimental field, applying LuDiLe - Liquid composite fertilizer to pastureland, Analyzing effect of applying fertilizer on forage yield and height on nature pastureland. The results showed that applying liquid composite fertilizer can increase forage yield and community height preatly. Considering from production angle, comparing treatment effect of applying different fertilizer amount, optimum applying fertilizer amount is 300kg/hm2 for mountain pastureland.
