摘  要:
通过人为控制种群密度的盆栽实验,研究羊草的高度生长和播种比例的关系以及羊草、冷蒿的地上生物量与播种比例的关系。结果表明:羊草的高度生长不受单播、混播的影响,其增长曲线为H=a+bt+ct2;不同的播种比例,羊草的生长速率不同。当两者株丛数接近相等时,冷蒿对羊草的高度生长有明显的抑制作用;株丛数相差较大时,冷蒿促进羊草的生长。对总生物量而言,羊草的混播比例增大不利于总体生物量的积累。

摘  要:
In artificial experiment,the population density was controlled to determine the interspecific relationship between Leymus chinensis and Artemisia frigida.The results was as follows: the height increase of Leymus chinensis was not effectel by single souing or mix-sowing,the regression curves equation of height increase of Leymus chinensis is H=a+bt+ct2(H is height,t is time of measuring).Rate of increased height of Leymus chinensis was affected by mix-sowing in different proportion.As to the total biomass,the increased proportion of Leymus chinensis is not favour for the total biomass accumulation,but on the other hand,mix-sowing is favour for the height increase of Leymus chinensis,but not good for Artemisia frigida.
