Abstract [Background] Water is the main limiting factor of plant growth and ecological restoration in vegetation afforestation in arid area. The inefficient use of soil moisture will lead to the waste of soil water in vegetation construction, soil dry layer, low ecological efficiency and poor vegetation growth. The application of water-retaining agents in arid zones can compensate for these shortcomings, and the best use of it for different plants needs to be studied.[Methods] In order to study the optimal amount of water-retaining agent for the growth of afforestation vegetation in arid area, 4 kinds tree species conserving soil and water, including two kinds of shrubs (Syzygium aromaticum and Swida alba Opiz) and two kinds of trees (Pinus tabulaeformis Carr, and Fraxinus chinensis Roxb.) were selected as the research object. During the growth period, the height and ground diameter of the plants were measured with steel tape and vernier calipers, and the soil water content was measured with a soil moisture meter. Then the plants were separated from the soil, the plants were washed and dried, and the root length, root surface area, root mean diameter, apical number and bifurcation number were analyzed by WinRHIZO root scanner and data analysis software. And the aboveground biomass and underground biomass were weighed.[Results] The soil water content of the test group was higher than that of the control group, and the soil water content increased with the increase of the concentration of the water-retaining agent. For two shrubs, the plant height, ground diameter and root index increased with the increase of water-retaining agent, and the biomass growth rate of clove and red wood was 20.73%-64.40% and 24.92%-98.21% respectively. The optimal amount of water-retaining agent was 20 g/plant. The plant height, ground diameter and root index of P. tabulaeformis and white wax decreased with the increase of the concentration of water retaining agent, the growth rate of biomass was 10.1%-56.58% and 7.04%-35.61% respectively. The higher concentration of water-retaining agent had inhibitory effect on the growth, and the two best water-retaining agent dosages were 5 g/plant and 10 g/plant.[Conclusions] The application of the water-retaining agent significantly affected plant growth and root morphology changes. 5-50 g/plant of the water-retaining agent applied to the clove and red Ruimu can promote the growth, the most suitable amount of 20 g/plant, Chinese pine water-retaining agent application range of 5-20 g/plant, the most suitable amount of 5 g/plant, white wax water-retaining agent application range of 5-30 g/plant, the most suitable amount of 10 g/plant.
