摘要
Abstract
Effects of soil on growth and fruiting of trees and biochemical characteristics of the soil were studied by planting non-timber species on both Chinese-fir-clear-cutting land and non-Chinese-fir-clear-cutting land．It's shown that organic matter，total nitrogen，hydrolysable nitrogen，available phosphate and contents of urease，proteinase，hydrogen peroxidase，etc．decreased to different extents，thus soil fortility declining．As a result，early growth of trees was suppressed to some extent，which was particularly obvious in such fast growing species as Vatica astrotricha and Phyllostachys pubescens．When Chinese-fir-clear-cutting land was reutilized，measures such as deep scarification and improvement of soil and application of basal manure were taken，with early fruiting，high yield and good quality obtained in Vatica astrotricha，Castanea mollissima，Ginkgo biloba，etc．Thus the sustainable utilization of Chinese-fir-clear-cutting land could be realized．关键词
