For the improvement of saline-alkali soil to overcome Texas greening difficulties, provide an effective way, described as follows: Because of the selection of tree planting in the saline-alkali green, to choose suitable for local growth, but also saline-tolerant species. Salinity in the high water area should also pay attention to choose water-resistant wet tree species. Through the observation and experiment in recent years, the tree species and flowers suitable for Dezhou include: Sophora japonica, white wax, white poplar, weeping willow, Fatong, acacia, Ailanthus altissima, Acacia, Tabor, hibiscus, pomegranate, Euonymus japonicus, crape myrtle, okra, chrysanthemum, rose, celosia, canna and so on.
