| 摘 要： | 在长白山林区通过野外调查、固定样地对比试验与分析,对水曲柳人工更新方式进行了研究。结果表明:水曲柳天然更新的幼苗幼树呈群团状分布,死亡率高;在皆伐迹地、荒山荒地等裸地栽植水曲柳,鼠害、冻害极为严重,幼苗、幼树死亡率高,幼树普遍枯稍,幼林生长缓慢。水曲柳在林隙环境下生长无霜冻等危害,可达到保存率高、速生、丰产、优质的目标。

| Abstract: | Artificial regeneration of Fraxinus mandshurica in forest range of Changbai Maintain was studied based on the survey and analysis of fixed plots in field contrast trial.The results are as follows: The seedlings and saplings by natural regeneration appear group in distribution with lower survival rate;Planted at cleared area or bare bill and(wasteland),the seedlings and saplings suffer from serious rats damage and freeze injury which resulted in higher(mortality) rate to the seedlings,topdrying to many saplings,so the young stand developed more slowly;Planted it(under) forest gap and frost-free zone,the stand would attain the goal of high preserving rate,fast-growing and high-yield as well as high-quality.It concluded that the artificial regeneration under forest gap created by secondary(stand) reformation is a scientific management mode. |
