Abstract
【Objective】 Study on keeping soil water and nutrient measures in the dry-hot valley areas was done in order to actualize the vegetation restoration of subgrade slope abandoned dreg site of hydropower station.【Method】 The experiment was carried out through four disposals for the soil of vegetation restoration experimental plot,and the four disposals were blank control,water retaining agent,water retaining and slowly-release fertility and water retaining agent+water retaining and slowly-release fertility.Jatropha curcas was planted in the plot.Under the same management conditions,the growth status of Jatropha curcas L.4 months later and dry season survival rate 12 months later were observed in order to compare the effects of the various disposals.【Result】 The results concluded that the treatments of water retaining agent,water retaining and slowly-release fertility and water-retaining agent + water retaining and slow-released fertilizer achieved good effect compared with blank control.Among them,the best effect was the disposals of water-retaining agent + water retaining and slow-released fertilizer.The treatments could promote the growth of Jatropha curcas L.and enhance its survival rate in dry season.The increasing rate of plant height,average leaf number,most leaf area,single weightiness and chlorophyl content increased by 43.50%,53.96%,17.60%×28.57%(length×breadth),37.95% and 6.87% compared with CK.The survival rate of Jatropha curcas L.in dry season increased by 96.38%.【Conclusion】 The treatments of water retaining agent + water retaining and slow-released fertilizer have certain application value in vegetation restoration of subgrade slope abandoned dreg site of hydropower station in the dry-hot valley.
