| 摘 要： | 通过马尾松与格氏栲、青栲、火力楠及杉木等树种混交试验,13年生时测定不同混交林土壤的持水性、土壤结构和养分。结果表明,马尾松格氏栲和马尾松青栲混交林土壤饱和持水量大于马尾松火力楠和马尾松杉木混交林,土壤结构破坏率以马尾松格氏栲和马尾松青栲混交林较低,而马尾松格氏栲混交林土壤孔隙度最大,且马尾松格氏栲和马尾松青栲混交林土壤有机质、全量养分和速效性养分含量高于其他2种混交组合。格氏栲和青栲为马尾松伴生树种可以促进林分涵养水源,提高土壤肥力。

| Abstract: | Through experiments on Pinu.s massoniana mixed with Castanopsis kawakamii , Cyclobalanopsis myrsinaefolia, Michelia macelurei ＆ Cunninghamia lanceolata etc. , soil water retention, soil structure ＆ nutrient at 13-year-old were determined with different mixed forests. Result shows that ： saturated water content of mixed forest of Pinus massoniana ＆ Castanopsis kawakamii , mixed forest of Pinus massoniana ＆ Cyclobalanopsis myrsinaefolia are more than that of mixed forest of Pinus massoniana ＆ Michelia macelurei, mixed forest of Pinus massoniana ＆ Cunninghamia lanceolata, soil structure destroy rate of mixed forest of Pinus massoniana ＆ Castanopsis kawakamii , mixed forest of Pinus massoniana ＆ Cyclobalanopsis myrsinaefolia are lower; soil porosity of mixed forest of Pinus massoniana ＆ Castanopsis kawakamii are the most;soil organic matter,total nutrient ＆ content of rapidly available nutrient of mixed forest of Pinus massoniana ＆ Castanopsis kawakamii, Pinus massoniana ＆ Cyclobalanopsis myrsinaefolia are higher than that of other 2 mixed combinations. Castanopsis kawakamii ＆ Cyclobalanopsis myrsinaefolia,which could accelerate water conservation of stand and increase the soil fertillty,are associated tree species for Pinus massoniana |
