【摘要】 研究结果表明 :蒌蒿群体的茎粗、分枝数和单株鲜重随扦插密度的升高而降低 ,单位面积叶片数和生物产量随扦插密度的升高而升高。产量与扦插密度间呈二次抛物线关系 ,扦插密度以 3 7.1 9～ 50 .0 0万株 /hm2 较佳。蒌蒿群体随扦插密度的不同在生物产量上表现出较强的自动调节能力更多还原

【Abstract】 The study results showed that the stem diameter,branch number and fresh weight per plant of the population of Artemisia selengensis decreased as its cutting density rose,the leaf number and dry matter weight per m\+2 rose as the cutting density rose. The relation between yield and cutting density could be simulated by quadratic parabola equation, the suitable cutting density of A.selengensis in protective cultivation is 37.19～50.00 ten thousand cutting wood per hm\+2.The population of A.selengensis could strongly autoregulate its dry matter weight under the condition of different cutting densities.\;更多还原
