Comprehensive measures for improving drought resistance of soil in cultivation of artificial vegetation

Cultivating artificial vegetation under drought circumstances needs to take adequate measures for drought resistance indispensably. Soil is a notable controlled object as carrier of water and nutrients required by plant growth and development, and reasonable treatments of it are closely related with drought resistance. Soil water storage, restraint evaporation, soil improvement and betterment of land fertility are beneficial to the using of limited water. The comprehensive measures for improving drought resistance of soil include several aspects such as soil tillage, soil fertilization, soil mulching and preventing water seepage to deep layer. In the background of the climate warming, in order to enhance the effects of measures for improving drought resistance of soil and raise their technical level, ways and characteristics of soil drought resistance measures concerning water storing, water retaining, water harvesting and water using were analyzed. Based on the synthetical review, issues on application of techniques for soil drought resistance measures and main aspects which needed to research for the future were also presented.
