摘要: 本文全面分析了低丘红壤区伏秋旱的成因、特征和抗旱措施。结果表明,降水量超前于潜在蒸发量变化及红壤调控、供水力弱、有效水少,供需矛盾突出是伏秋旱的主因。其特征是频率和强度加大、干热同步、表土干旱。关键对策是建立开源节流为主体、降耗增效为两翼的抗旱技术体系。

Abstract: his paper has analysed the causes and properties of the mid summer and autumn droughts and the countermeasures of drought hazard in the low hill red soil region. The results are as follows.The main causes are that most precipitation occurs earlier than the latent high evaporation in the region, the space in red soil for water storage is limited, and less water is available for crop use. The properties are that drought and high heat occur at the same time, surface soil becomes dry rapidly, and the contradiction between supplying water from soil and requiring water for crops is obvious. The countermeasure is building a technical system for combating the drought. Of which, developing water resource and saving using water are the main body and reducing the unproductive water consumption and increasing the utilization ratio of the water resource by organisms are two wings.
