摘要：
Research on the measures to conserve soil water and nutrient in the dry-hot valley areas was conducted in order to realize the vegetation restoration of abandoned dreg site of hydropower station. The experiments indicated that soil in the abandoned dreg site with water retaining agent + water-retaining and slow-released fertilizer could achieve the best effect in compasion with the control. The treatment could stimulate the growth and development of Leucaena leucocephala and improve its survival rate in dry season. The increasing rate in plant height, average leaf number, most leaf area, single weightiness and chlorophyl content increased by 32.74%, 23.86%, 11.51%×14.58%(length×breadth), 53.49% and 7.88% compared with CK. The survival rate of Leucaena leucocephala in dry season increased by 94.97%. The disposals of water retaining agent + water retaining and slow-released fertilizer have certain application value in vegetation restoration of abandoned dreg site of hydropower station in the dry-hot valley.
