天然阔叶林皆伐迹地人工封促成林试验研究

Study on artificial regeneration in cleared areas of the natural broad-leaved forest

本文通过对天然阔叶林皆伐迹地,采用人工封促成林与自然更新二种不同更新方法的对比试验,结果表明:采用人工封促成林的更新方法具有明显的优点,即投资少、效益大,林木生长快,单位面积蓄积量可提高50.7%,建议有条件的地方应推广使用该方法,为发展阔叶林生产,保持生态平衡提供了一条有效的途径.

In the natural broad-leaved forest clearing areas, there is compared test between artificial regeneration and natural regeneration. The result shows that the artificial regeneration is lower investment, gaining more benefits, and seadlings growing faster than natural regeneration and the former cause the stand volume per hectare increasing to 50. 7 percent. Based on these results the anthor give a certain of recommendations of using artificial regeneration in broad -leaved forest clearing areas.
