    摘要:

    干旱条件下培育人工植被,采取适当的抗旱措施是必不可少的,其中作为植物生长发育所需水分、营养的载体,土壤是显著的可调控对象,对其合理处置与抗旱有着密切的关系。以土蓄水、抑制蒸发、改良土壤、培肥地力等有利于对有限水分的利用。提高土壤抗旱性的综合措施包括土壤耕作、土壤培肥、土壤覆盖、防止水分深层渗漏等方面。在气候暖化的背景下,为增强土壤抗旱措施的效果,提高其技术水平,分析了与蓄水、保水、集水以及用水有关的土壤抗旱方式及其特点。在综合述评的基础上,还讨论了土壤抗旱措施的技术应用问题和需要研究的主要方面。

    Abstract:

    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.
