Arundo donax Linn.was selected as representation of giant grass.The main growth factors,planting materials and soil texture were analyzed by several spot experiments in Beijing.The result showed that A.donax was able to endure drought and leanness.The survival rate was above 85%.It grew normally in the soil where the organic matter level was 0.413%.Moreover,depending only on precipitation,A.donax grew with high biomass.The overwintering survival rate of A.donax increased significantly if some protection measures were taken,and harvesting in March of next year was one of the most feasible measures.

通过田间小区实验, 研究了栽培措施(遮荫强度、移植时间和修剪时间)对观赏植物狼尾草生长的影响。结果表明: 狼尾草株高和冠幅随着遮荫强度的增加而增加, 但花序数却明显减少; 不同移植时间对狼尾草的成活率均无影响, 成活率可达100%; 越冬前修剪后覆土的养护措施显著降低株高与花序数, 延迟了生育期。
