晋西黄土丘陵区不同人工林下土壤养分性质研究
Study on Soil Nutrients under Different Plantations in Loess Hilly Region in Western Shanxi
摘要
Abstract
To study the similarities and/or differences of soil nutrients under different plantations in the loess hilly region in western Shanxi, soil surface layer(0 - 20 cm) and lower layer(20 -40 cm) under 4 typical plantation types were chosen,whose organic matter, nutrients (total N,P, K,available N,P,K) and pH value were measured and compared. The result showed that the nutrient content of different plantations had a significant vertical difference,and that in the surface layer (0 - 20 cm) was higher than the lower layer (20 - 40 cm) except total K. By correlation a-nalysis and principal component analysis, a significantly positive correlation was shown between soil organic matter and total nitrogen,available nitrogen. And the general scores of soil nutrients under 4 kinds of plantation mode were ranked as follows; mixed forest,artificial broad-leaved forest artificial coniferous forest and shrub forest.关键词
