Abstract:: Fiftyone kinds of herbaceous succulents,12 genera of Crassulaceae,two genera of Aizoaceae,one genus of Portulacaceae,one genus of Labiatae were used as test materials,used selection experiment of cultivated varieties in rock desertification.The results showed that most of the winter type succulent plants in the experimental materials could adapt to the low temperature in winter and generally grew well,in addition to individual species include Sedum burrito and Sedum sediforme affected by low temperature leading to a poor growth and the final death.Part of summer type,the spring and autumn type of the succulent plants gone into dormancy,safely crossed the winter.Thirty species of succulent plant were successfully screened for overwintering in rocky desertification.Including 11 genera of Sedum,one genus of Aizoaceae and one genus of Portulacaceae.The experimental results provided valuable basic data for the horticultural production and landscape application of the succulent plant in the rocky desertification of Guiyang.
