摘要
1998年在中国科学院内蒙古草原生态系统定位研究站进行的试验结果表明,施N肥和P肥均使草地生产力显著提高;N肥以225kg/hm2尿素较为适宜,P肥以150kg/hm2过磷酸钙较为适宜;在混播草地中,施N肥和P肥对羊草+草原2号苜蓿草地与无芒雀麦+草原2号苜蓿草地增产效果都很显著,相对来说前者比后者更好。
The experiment was conducted at IMGERS in 1998. The results showed that applied fertilizer N and P could significanty increased biomass of artificial grassland. The suitable amount of urea and superphosphate was 225kg/hm\+2, 150kg/hm\+2 respectively. N and P fertilizer could remarkably increased biomass of mix sowing grassland. The biomass of mix sowing Leymus chinensis and Midicago was more than mix sowing Bromus inermis and Midicago.
