北方干旱地区抗旱造林实用技术研究

Research on Practical Techniques for Drought Resistant Afforestation in Arid Areas of Northern China

我国北方地区气候比较干旱,有的地区有效降水少,土壤含水量低,采用常规造林技术难以实现一次造林即成林的目标。在干旱地区造林,需要根据当地气候条件以及立地条件采用抗旱造林技术,提高造林成活率。因此,从抗旱树种选择、整地技术和造林技术等方面总结北方干旱地区的实用造林技术要点,具有现实指导意义。

The climate in Northern China is relatively arid,with some areas having less effective precipitation and low soil moisture content.It is difficult to achieve the goal of afforestation in one go using conventional afforestation techniques.In arid areas,it is necessary to adopt drought resistant afforestation techniques based on local climate and site conditions to improve the survival rate of afforestation.Therefore,summarizing the practical afforestation techniques in Northern arid areas from the selection of drought resistant tree species,land preparation techniques,afforestation techniques,and other aspects has practical guiding significance.
