摘要
通过对永春本地和从广东罗定县引进的马尾松造林后采取的集约经营和一般经营两种措施比较,结果表明,集约经营的本地松和罗定松10年生时其平均木生物量与一般经营的本地松相比提高20%以上,集约经营的马尾松与一般经营相比,土壤容重下降而土壤持水量和孔隙度增加,土壤有机质和速效磷含量提高,集约经营的马尾松林土壤理化性质得到改善。
Two measures of intensive management and general management after reforestation of Pinus massoniana which grew in Yongchun and introducted from Luoding County of Guangdong Province were compared,the results showed that the average wood biomass intensive management of 10-years P.massoniana in Yongchun and Luoding was higher than the general operation of local pine by 20%,and intensive management of P.massoniana,compared with the general,soil bulk density decreased and soil water holding capacity and porosity increased,soil organic matter and content of available phosphorus increased,soil properties of P.massoniana forests with intensive management were improved.
