| 摘 要： | 为评价能源型植物柳枝稷Panicum virgatum在贫瘠沙化的边际土地生境上的适应性,采用盆栽试验研究了壤土(对照)、3种边际土(面砂土、粗砂土、砾石土)和3种移栽方式(营养钵、裸苗、裸苗+营养土)对柳枝稷苗期生长的影响。结果表明:在3种沙化贫瘠的边际土壤中柳枝稷幼苗均能正常生长,随着土壤养分含量升高,柳枝稷的株高、分蘖数、主茎叶片数和干物质积累量均显著增加;裸苗移栽方式较营养钵移栽方式不利于柳枝稷苗期生长,其成活率、株高、分蘖数和干物质积累量均显著降低;裸苗+营养土移栽较裸苗移栽显著提高了柳枝稷裸苗的成活率,建议作为柳枝稷边际土地种植方式。

| Abstract: | Switchgrass (Panicum virgatum) is a widely adapted perennial (C4) grass and a potential bioenergy crop. The objective of this study was to determine the effect of marginal land types and transplanting methods on the establishment of switchgrass seedlings. One loam soil (CK) and three typical marginal land soils(sandy soil,coarse sand,and gravel soil) as well as three transplanting methods(nutrition pot,root-naked and root-naked plus nutrient soil) were used in this study,which was carried out using potted e... |
