我国南方亚热带地区广泛分布的红壤和黄壤适于多种林木生长,但由于侵蚀严重,有的地方甚至底土裸露,沟壑纵横,急需植树造林,恢复植被,保持水土。今年西南五省区遭遇了百年一遇的特大旱灾,林业损失惨重。科学抗旱保苗,提高造林成活率显得尤为重要,这里简要介绍几种实用抗旱造林技术,供各地参考。 Red soil and yellow soil, which are widely distributed in the southern subtropical region of China, are suitable for growing a variety of trees. However, due to the serious erosion, some areas are bare and ravines are sometimes exposed. Trees are needed for afforestation, vegetation restoration and water and soil conservation. This year, five provinces and autonomous regions in Southwest China suffered a serious drought once in a century, and the forestry suffered heavy losses. Scientifically drought-resistant and seedling raising afforestation survival rate is particularly important, here a brief introduction of several practical drought afforestation techniques for reference.
