黑地膜覆盖对闽楠切杆裸根造林幼林后期生长的影响

The Effect of Black Mulching on the Growth of Seedling in the Late Stage of the Seedling of Phoebe bournei Cutting Bole

在劳动力短缺和造林抚育费用不断走高的情况下,探索黑地膜覆盖对闽楠人工幼林生长及抑制杂草生长的影响,为提高闽楠人工造林成效,以及降低造林后人工管护成本提供直接参考。用1年生闽楠裸根切杆苗进行黑地膜覆盖造林,3年后对树高、地径和树冠进行了单株调查和统计分析,试验结果表明:黑地膜覆盖对幼林后期地径生长有促进作用,但能抑制树高生长;可以有效减少人工除草等生产管护成本,有利于提高幼林生长质量,对幼林生长前期并无显著影响。

The effects of black film mulching on the growth of young artificial forest and the growth of weeds in Phoebe bournei were studied in this paper in order to improve the effect of artificial forestation and reduce the cost of artificial forest management after forestation. After planting with black plastic film, the experiment of cutting stem seedlings of one-year-old Phoebe bournei bare root seedlings has been carried out. After three-year growing, the tree height, ground diameter and crown of Phoebe bournei hare root seedlings were investigated and statistically analyzed. The results showed that： covering black plastic film on young artificial forest of Phoebe bournei can reduce the production cost of artificial weeding, which is positive to improve the growth quality of young forest, and has no significant effect on the early growth stage of young forest.
