松土抚育对闽楠林地土壤物理性质及林木生长的影响
Effects of Soil Loosening Operation on the Soil Physical Properties and Tree Growth in Phoebe bournei Plantation
摘要
Abstract
In order to cultivate large diameter timber of Phoebe bournei,we conducted a 3-year soil loosening experiment on Phoebe bournei middle-aged stands.The main findings are as follows:loosening the surface soil,causing a decrease in soil bulk density,which increases year by year over time;an increase in soil capillary and non capillary pores,which decrease year by year;an increase in the natural moisture con-tent and maximum water capacity of the soil,and over time,the natural moisture content and maximum water capacity decrease year by year;the growth of stands is accelerated,and the diameter at breast height,tree height,and volume growth are significantly higher than those of for-ests without loose soil,and the larger the soil loosening area,the better the growth.For cultivating large diameter timber of Phoebe bournei,it is recommended to do soil loosening operation every 3-5 years.关键词
