杉木马尾松木荷混交林生产力研究

Study on Productivity of Mixed Forests of Chinese fir Plantations with Pinus massaniana and Schima puperba

通过对 1 5年生杉木、马尾松、木荷纯林及其 4种不同混交林共计 7种试验处理的调查 ,从林分生长状况、林下土壤养分和生物量空间分布格局 3个方面进行对比分析 ,结果表明 ,4种混交林在以上 3个方面均优于杉木、马尾松、木荷纯林 .

Observation and analysis were made on pure and mixed forests of Chinese fir,Pinus massaniana and Schima puperba from the condition of stand growth, soil nutrient and biomass of mixed plantations were improved while compared with their pure plantations,the forest structure and nutrient status of soil were also improved.So the results could be used to conduct plantations production management.
