摘要
对秃杉檫树混交林、秃杉杉木混交林及秃杉、杉木纯林的生产力及其土壤理化性质进行研究,结果表明:秃杉混交林的生产力高于秃杉、杉木纯林,混交林中以秃杉檫树混交林的生产力最高;秃杉混交林对土壤理化性质改善作用强于秃杉和杉木纯林,秃杉檫树混交林改土效果最明显;秃杉生长速度快于杉木。
Productivity and soil physical and chemical properties of mixed forest of Taiwania flousiana with Sassafras tsumu and Cunninghamia lanceolata ,pure stand of Taiwania flousiana and Cunninghamia lanceolata was studied in this paper.Results showed that productivity of mixed forest of Taiwania flousiana was much more than pure stand of Taiwania flousiana and Cunninghamia lanceolata. The productivity of mixed forest of Taiwania flousiana and Sassafras tsumu was the highest of all the mixing stand.Improvement function on soil physical and chemical properties of mixing stand of Taiwania flousiana was greater than pure stand of Taiwania flousiana and Cunninghamia lanceolata. The mixing stand of Taiwania flousiana and Sassafras tsumu had the most significant effect to improve soil fertility. Taiwania flousiana grew faster than Cunninghamia lanceolata.
