摘要
对 4年生肉桂林和杉木萌芽林的土壤肥力进行对比研究。结果表明 :肉桂林的土壤结构、水分状况、孔隙组成和渗透性能均比杉木萌芽林好 ,土壤有机质、全 N、全 P、全 K和速效养分含量也比杉木萌芽林有所增加。说明肉桂林取代杉木林后 。
In this paper,analysis on soil fertility on fourageyoung Cinnamomum cassia stand,compared with Chinese fir sprout stand.The results showed that soil moisture condition,soil structure,pore space condition,and permeation capacity had been improved,and the content of soil organic matter,total N,total P,total K and available nutrients were increasing.Therefore,the soil fertility were promoted pronouncedly by the replacement of Chinese fir stand by the Cinnamomum cassia stand.
