建国以来,黑龙江省更新造林面积已过275万公顷,孟家岗、通天一、青山、林口场局成为我省更新造林的典范。但就全局而言,我省在更新造林速度,造林保存率及生长率三方面与预计目标存在着差距。为加速林木生长,提高更新造林成效,建议采用生物措施,提高更新质量。
Since the founding of the People’s Republic of China, the area for afforestation in Heilongjiang Province has exceeded 2.75 million hectares. Mengjiagang, Tongtian I, Castle Peak and Linkou Bureau have become the model for reforestation in our province. However, in terms of the overall situation, there is a gap between our province and the projected target in terms of the rate of afforestation, the rate of afforestation preservation and growth rate. In order to accelerate the growth of trees and improve the effectiveness of afforestation, it is proposed to adopt biological measures to improve the quality of renewal.
