Abstract:
Taking one-year-old seedlings of S.moorcroftiana as experimental materials,the effects of water retainer on the growth,physiology and rooting indexes of Sophora moorcroftiana seedlings were studied by setting five water retainer dosages (CK,T1,T2,T3,T4),in order to provide reference for the best water saving mode of S.moorcroftiana and efficient use of water.The results showed that the height,ground diameter and biomass of S.moorcroftiana seedlings could be increased with the increase of water retainer concentration.The seedling height,ground diameter and biomass of seedlings reached the maximum under T2 treatment,and all increased first and then decreased with the increase of the concentration of water retainer.The application of water retainer increased the chlorophyll content and root activity of S.moorcroftiana.The content of malondialdehyde,superoxide dismutase,peroxidase and proline were decreased by applying water retainer.The root biomass,total length,surface area and volume of S.moorcroftiana seedlings reached the maximum under T2 treatment,and all increased first and then decreased with the increase of water retainer.Within the range of appropriate addition amount,the application of water retainer agent could improve the growth of the seedlings of S.moorcroftiana,but when the application amount was too large,it would hinder the normal growth of the seedlings of S.moorcroftiana. In this study,the amount of T2 (0.2%) water retainer had the best effect.
