适宜水曲柳造林的主要方式

Suitable methods for Praxinus mandshurica afforestation

水曲柳(Praxinusmandshurica)是黑龙江省山河屯林区人工更新造林的主要树种之一,其具有很高的经济价值。通过多年的生产实践与试验研究,证明应用一年生苗进行春季人工植苗这一常规方法造林,幼苗缓苗期较长,幼林期生长缓慢,未能充分发挥出水曲柳优良的遗传特性;而应用水曲柳直播造林技术和水曲柳与落叶松混交造林,可以促进幼林生长量的提高,提高林地生产力。

Praxinus mandshurica is one of main afforestation species and has high economic value.According to many years' production practice and research,the results show that young period is long and growth speed is slow using conventional method of stock planting forestation at spring.And Praxinus mandshurica's excellent features can't be exhibited.But using the technique s of direct seeding afforestation and mixed forest forestation with larch,young plantation growth and productivity of forest lands can be improved.
