本文研究了卧龙自然保护区大熊猫栖息地内拐棍竹根系结构特点。结果表明,柺棍竹根系最常见分布区一般在秆基第13节～19节;地下茎龄级越小,根在地下茎上着生的位置越远离秆基竹秆端即节序越大;根系在土壤中的分布与地下茎在土壤中的分布特点基本一致;不同龄级柺棍竹地下茎上根的条数是有差异的,但彼此相差不大,幼嫩地下茎和较老地下茎上的根相对较少;根的直径随地下茎龄级的增加而减小。

In this paper studies were made of the features of roots structure of Fargesia robusta in giant panda habitat of Wolong National Nature Reserve.The results showed that generally the roots of Fargesia robusta were mostly distributed between the 13th and 19th node of the stem base;the smaller the age-class of rhizome,the farther away from the end of rhizome close to the stem base the position of roots on the rhizome;the distribution feature of roots was the same as that of rhizome in the soil;the number of roots on the different age-class were variant,but the difference was not too big,and roots on the young and old rhizomes were relatively less;the diameter of rhizomes decreased with the increase of the age-class.
