摘要
为了探索适合在北方干旱地区造林中大面积推广应用的土壤覆盖措施,提高人工造林的成活率,开展了不同土壤覆盖措施对侧柏林间土壤含水量及造林成活率的影响试验,结果表明:土中覆草的处理蓄水能力更强,明显促进侧柏苗木生长,提高苗木的成活率。我国北方干旱地区应用土中覆草技术可明显提高造林成效。
In order to explore the soil cover measures suitable for large-scale application and extension in afforestation in the arid regions of northern China, and improve the survival rate of artificial afforestation, the effects of different soil cover measures on soil water content and afforestation survival rate of Platycladus orientalis were tested. Result shows that: The treatment of soil covering grass is more powerful, which obviously promotes the growth of Platycladus orientalis seedlings and improves the survival rate of seedlings. The application of soil-covering techniques in the arid regions of northern China can significantly improve the effectiveness of afforestation.
