| 英文摘要 | Water is a key limiting factor for vegetation restoration in the semi-arid areas of china. caragana korshinkii kom is a shrub that is widely planted in this region to control soil erosion and land desertification. the objective of this study was to investigate the fine root distribution of mature c. korshinkii and its water consumption, when grown in either silt loam or sandy soils, in order to understand differences between the water cycles of two such soils found in the transition zone between fertile loess hills and desert of the northern loess plateau. fine root distributions were measured using the trench-profile method. soil water dynamics were monitored with a neutron probe during two growing seasons. the results showed that fine root area density (frad) declined with increasing soil depth in both soils, with 70.7% and 96.6% of the total fine roots being concentrated in the upper 1-m layer of the silt loam and sandy soils, respectively. water consumption by c. korshinkii in the silt loam was close to that in the sandy soil. most water consumption in both soil types was from the upper 1-m layer. little variation in plant available water ( paw) occurred in the 3-6 m soil layer during the whole study period. however, in this layer, the paw was significantly lower in the silt loam soil than in the sandy soil. total actual evapotranspiration (et(a)) was slightly higher from the sandy soil plots than from those of the silt loam soil during both growing seasons. our study indicated that mature c. korshinkii effectively uses about the same amount of water from either the silt loam or sandy soils, but that more soil water at depth was extracted from silt loam soil than from sandy soil. |
