提高多年生人工草地建植当年产草量的研究

Study on the Grass Output Increasement in the Establishing Year of Artificial Perennial Grassland

研究结果表明，在高寒牧区建植多年生人工草地，适当混播燕麦不仅可显著提高播种当年的产草量，而且对提高前两年产草总量亦有效果。在老芒麦与燕麦的混播组合中，以老芒麦每公顷用种量３０ｋｇ、燕麦每公顷用种量７５ｋｇ，可形成较合理的群体结构。

When establish an artificial perennial grassland in the cold highland pastoral area,sowing mixed with oats (Avena sativa) properly not only can increase the grass output in the first year but also can improve the total output in the first two years.Sowing Elymus Sibiricus Svi 30Kg per hectare mixed with oats 75Kg per hectare can form a reasonable population composition.
