发展间作套种经济是促进农民增收的有效途径。在水资源严重短缺的情况下，对间作套种的作物如何实施高新节水灌溉问题进行研究具有非常重要的现实意义。为此，引入双支管滴灌系统技术，并以新疆皮山县为例，对红枣套种棉花进行了双支管滴灌的设计。实施和运行结果表明，双支管滴灌系统有效地解决了间作套种情况下的作物灌溉问题，为今后在立体种植模式条件下的滴灌设计提供了重要的技术依据和宝贵的实践经验。

Development of intercropping economy is an effective solution to increase farmers’ income, especially in the area short of water resources. Therefore, the implementation of high-tech water-saving irrigation on the intercropping crops has received more attention and its research is of great practical significance. In this paper, the concept of two-branch-pipe drip irrigation system is proposed and applied to the intercropping of red date and cotton in Pishan county, Xinjiang province of China. The successful implementation and operation of the drip irrigation system can solve the irrigation problems for the intercropping crops, which may provide important technical support and valuable practical experience for the future stereo planting pattern.
