辽西北典型人工林地不同坡位土壤养分特征及与林木生长性状的关系
Soil Chemical Properties and Their Relations with Stand Growth of Typical Afforestation Tree Species in Northwest Liaoning Province
摘要
Abstract
An investigation was carried out on the soil nutrients of the forests of Pinus sylvestnis var.mongolica and P.tabulaeformis in 3 locations in Lingyuan,Jianping,and Fuxin of Liaoning Province.Twentyfour sampling plots were set,and soil samples were collected in different slopes (upper,middle and lower slope) and layers (0-15 15-30 cm).The results indicated that 1) the order of the soil nutrients was lower ＞ middle＞upper slope,in which significant differences were observed in total N and total P.2) The relations of soil nutrients in lower slope was higher than those in middle and upper slopes,and all had reached to significant level.3) The correlations of soil nutrients and growth traits in lower slope were more significant than those in middle and upper slope,and all had reached to significant level.Overall,the soil nutrient in surface soil under lower slope could significantly affect the growth traits of the two tree species,and therefore,relative forest management should be adopted.关键词
