中文摘要	对新疆焉耆盆地平原盐漠草地中的黑果枸杞(Lycium ruthenicum)灌丛与根系组成及分布特征进行了研究。结果表明,黑果枸杞灌丛由新老株丛构成,常以几近平行的多行排列分布;其根系为根蘖型,主要由水平根及根蘖形成植株的地下垂直茎组成,不定根作为一个特殊组成部分,具有明显的季节性和特定性,仅在7月后参与木质化的水平根和地下垂直茎组成的根系系统上发生;水平根分布于50cm左右深的土层,具有分蘖和继续分生水平根的特性;地下垂直茎具有在地下多级分生的特性。地下生物量占总生物量的平均鲜重比例为33.2%,根系所在的土壤含水量在13.7~19.1%。
英文摘要	The composition and distribution characteristics of Lycium ruthenicum brush and root system were studied in the desert grassland in Yanqi basin.The results showed that the shrub of L.ruthenicum consists of old and new clump with parallel of multi-line distribution.The roots of L.ruthenicum were root sucker type-underground vertical stem mainly formed by the horizontal roots and root turion.Adventitious roots,as a special part,had obvious seasonal and specific characteristics which involved in the formation root system of lignified horizontal roots and underground vertical stems after July.Horizontal roots distributed in the soil about 50 cm deep and continued to produce other horizontal roots and underground vertical stems.Underground vertical stems with a multi-level underground meristem and other characteristics. The percentage of underground biomass in total fresh biomass was 33.2%,where the soil moisture in the root system was between 13.7 to 19.1%.
