    摘要:

    为了解毛竹(Phyllostachys edulis)细根的分布规律,对不同水平距离和土层深度0~1 mm和1~2 mm细根的生物量、比根长、组织密度和根长密度进行了分析。结果表明,随着毛竹年龄的增加,细根生物量和根长密度先上升后降低,根组织密度先降低后升高,比根长呈降低的趋势。细根生物量和根长密度以距竹秆60 cm处最大,根组织密度以20 cm处最大,比根长在40 cm处最大,但他们在距竹秆不同距离间的差异不显著。细根生物量以10~20 cm土层最大,根组织密度以20~30 cm土层最大,细根生物量、比根长、组织密度和根长密度在不同土层间的差异不显著。与1~2 mm细根相比,0~1 mm细根生物量和根组织密度更小,比根长和根长密度更大。因此,毛竹年龄对细根生长具有显著的影响,1年生毛竹有最大的比根长和较大的根组织密度,具有更强的资源利用率。毛竹细根在一定的土层范围内呈均匀分布状态,可更有效地利用特定区域的水肥资源。

    Abstract:

    The aim was to elucidate fine root biomass distribution differences of moso bamboo (Phyllostachys edulis) at different ages. The fine root biomass (WFRB), specific root length (LSRL), root tissue density (DRTD), and root length density (DRLD) were analyzed in the horizontal and vertical direction of different age moso bamboo. The results showed that along the age of moso bamboo, the WFRB and DRLD increased at first and then decreased, the LSRL decreased, and the DRTD decreased at first and then increased. The WFRB and DRLD were the biggest at 60 cm from main stem, the DRTD and the LSRL were at 20 cm and 40 cm, respectively. The differences of WFRB, LSRL, DRTD and DRLD were not significant among different horizontal distances from bamboo stem. The WFRB was the biggest at 10-20 cm soil layer, and the DRTD was at 20-30 cm soil layer. The differences of WFRB, LSRL, DRTD and DRLD were not significant among different soil depthes, too. The WFRB and DRTD of 0-1 mm fine roots were smaller than those of 1-2 mm fine roots, while the LSRL and DRLD were bigger. Therefore, the age of moso bamboo had significant effects on the growth of fine roots. The LSRL and DRTD of 1-year-old bamboo were bigger, which display greater resource utilization efficiency. The even distribution of fine roots of moso bamboo could more efficient use water and fertilizer resources in a particular area.
