| 摘 要： | 通过对苜蓿 无芒雀麦混播人工草地进行了株高动态、产草量动态研究,结果表明:从整个生长季采看,混播降低了苜蓿的草层高度,增加了无芒雀麦株高.播种当年混播草层产草量高于单播草层,第二年,混播草层产草量低于单播苜蓿产草量,混播草层最高产草量到达时间晚于单播草层. |

| Abstract: | The dynamical studies on the height and yield of mixed grassland were conducted.The results showed that in all seasons,mix-sowing decreased the Medicago's height,but raised those of Bromus inermis.The yield of mixture grassland was lower than that of corresponding single Medicago grassland in first year.The yield of mixture grassland was higher than that of corresponding single Medicago grassland in the second year.The time when mixture grassland reached its maximum biomass was later than that of single grassland. |
| Keywords: | mix-sowing grassland height yield |
