摘　　要：通过在草甸草原轻度退化割草地上喷施多功能肥料,对比施肥前后割草地草群的高度、盖度和地上生物量变化情况,分析轻度退化割草地喷施肥料后的植物群落特征变化趋势。研究结果表明,喷施叶面肥对割草地草群的盖度影响不大,但能够明显提高草群的高度和地上生物量,施肥2年割草地的草群高度较对照草群平均增加了7.32 cm,草群地上生物量增加了39.42 kg/667 m^2。This study analyzed the changing characteristics of plant community in mowed grassland of slightly degraded meadow steppe before and after spraying the multi-functional fertilizer,including the height,coverage and above-ground biomass of grasses.The results showed that the application of foliar fertilizer had minor effect on the coverage of grasses in the mowed grassland,but it could significantly increase the height and above-ground biomass of the grasses.The grasses height of the grassland receiving 2-year-long fertilization was averagely 7.32 cm higher than that of the control,and its above-ground biomass of the grasses had an increase of 39.42 kg/667 m^2.
