摘要
研究了不同采伐季节对沙柳平茬后再萌生能力的影响,分析了沙柳春夏秋冬四季平茬后再萌生的枝条数量、平均直径及成活率。结果表明:春季平茬沙柳再萌生枝条成活率最高,而且枝条生长状况良好,平茬后枝条数量多且平均直径大,因此春季沙柳平茬后的再萌生能力最强。
The effect of different harvest seasons on the re-sprouting ability of Salix psammophia are studied, the number of re-sprouting branches,average diameter and survival rate of Salix psammophia forest after stumping in four seasons, with the result showing that in summer,survival rate of re-sprouting branches is the highest,in good condition,with the largest number of branches and the largest average diameter,indicating the strongest re-sprouting ability of Salix psammophia in summer.
