| 摘 要： | 以南京溧水林场25年生的杉木人工林为研究对象,探讨了间伐对杉木人工林1～5级细根平均直径、长度和比根长的影响.结果表明:杉木人工林细根平均直径和根长随根序等级的增加而显著增加(p＜0.01或P＜0.05),而平均比根长则显著下降(p＜0.05).在杉木人工林5级根序中,1级细根平均直径最小、根长最短、比根长最高,5级根...

| Abstract: | An experiment was conducted to study the effects of thinning on fine root diameter,length and specific root length(SRL) of the first to fifth order roots in Chinese fir plantations in Lishui Forest Farm of Nanjing.Results showed that,with ascending root orders,the mean fine root diameter and length increased,while the mean SRL decreased significantly.Among the five orders of roots,the first order roots were the thinnest in diameter,the shortest in length,and the highest in SRL,but the fifth order roots were... |
