浏阳大围山土壤研究初探

在阐述浏阳大围山森林土壤形成条件的基础上，重点阐明了大围山各类土壤的理化性质、肥力特点及土壤垂直分布规律。大围山土壤土层深厚，质地较轻，pH值为4．5∽5．4，养分丰富，N、P、K含量较高；大围山土壤分布自下而上依次为山地红壤、山地黄壤、山地黄棕壤和山地灌丛草甸土，在海拔1100m以上的山间盆地和凹地间有草甸、沼泽土分布。

Study on the soil of Dawei Mountain in Liuyang City

Dawei Mountain is located in Liuyang County, Hunan Province. In this paper, based on the forming condition of the forest soil, the chemical and physical nature, the soil fertility characteristics as well as the soil vertical distributing law. In this mountain area, the forest soil layer is thick, and the soil texture is loose. The pH of the soil is about 4.5 to 5.4, N-nutrient is abundant, the N, P, K contents is higher.Soil distribution from the foot to the top were: mountain red soil, mountain yellow soil, mountain yellow-brown soil and mountain meadow soil. Above the 1100 m of absolute altitude of the intermountain basin is bog soil.
