摘要
为研究地被植物对古树周边土壤性状的影响,在古银杏、古广玉兰周边恢复不同的地被,并对土壤的理化性质进行测定。结果表明:古广玉兰周边恢复木蓝1年后,土壤的理化性质得到改善;古银杏周边恢复不同地被植物后,土壤微生物量有显著变化。
For the purpose of studying effect of ground plants on soil behavior around old trees, various ground plants surrounding old ginkgo and widely magnolia were recovered and physical and chemical characteristics of soil were determined. The results shows replanting lily magnolia around widely magnolia can sufficiently improve physical and chemical characteristics of soil after one year; different ground plants covered around old ginkgo, amounts of microbiology in soil. increase remarkably.
