在美国宾夕法尼亚州的东北部,“彭格菲”(Penngift)小冠花已成功地应用于控制山坡侵蚀,人们喜欢小冠花,它不需要更多的管护就能生长。通过对宾夕法尼亚州的实际观察使我们了解到:在贫瘠的土壤上可以种植各种根系发达的灌木和藤本植物,能够有效地防治陡坡(1/2:1)的侵蚀,许多地方种植的日本忍冬有力地回答了这个问题。然而在调查中进一步了解到短时期内,在迅速发展的市郊陡坡种植忍冬是不切合实际的。
In the northeastern state of Pennsylvania, “Pengoift” Crown of the Crown has been successfully used to control hillside erosion and people love small crown flowers that grow without requiring more tube care. Through the actual observations in Pennsylvania, we have learned that we can grow a variety of shrubs and vines rooted in poor soil so that we can effectively control the erosion of steep slopes (1/2: 1) and many parts of Japanese honeysuckle Powerfully answered the question. However, in the survey, it was further learned that in a short period of time it would be impractical to plant honeysuckle on the steeply-growing suburban steep slopes.
