STUDIES ON THE CHARACTERISTICS OF STRUCTURE AND MOISTURE PROPERTIES OF THE SOIL IN COMPLEX AGREFERESTRY MANAGEMENT SYSTEM OF CHINESE FIR.ALEURITES FORDII HEMSL AND EONE CHINESE BENTH

对福建建瓯杉木、油桐、仙人草复合经营的土壤结构特性与水分性质进行较为系统的研究,结果表明,该复合系统运行8年后,由于油桐和仙人草的覆盖,使杉木幼林免遭雨滴直接袭击,加上油桐落叶与根系及仙人草宿根的作用,与未套种杉木林地相比,土壤结构特性和水分性状得到一定程度的改良。

This paper studies the characteristics of structure and moisture preperties of the soil in the a-grotorestry system of Chinese fir. Aleurites fordii Hemsl and Eone Chinese Benth in Jianou County. As a result of beneficial cover of Aleurites fordii Hemsl and Eone Chinens Chinensis Benth where soil of the young Chinese fir stand avoids the straight hit of rainfall, and dur to beneficial effects of fallen leaves and roots system of Aleurotes fordii Hemsl and perennial roots of Eone Chinensis Benth, the characteristics of structure and moisture properties of soil are improved after adopting the comples agro-foestry management system of Chinese fir, Aleurites ferdii Hemsl and Eone Chinensis Benth for 8 years.
