新疆盐碱地棉花膜下滴灌的特性分析

根据新疆的气候特点、土壤结构、水资源现状，研究盐碱地膜下滴灌条件下水分和盐分的运动规律、施肥种类和施肥量、改良盐碱地和利用微咸水滴灌、对棉花产量和品质以及对土壤热环境影响方面的特性。结果表明：在新疆的盐碱地应用棉花膜下滴灌技术既节水、节肥、节能、保墒、改良土壤盐碱化，又有相当明显的经济效益、社会效益、生态效益。对水资源的合理配置和节水灌溉系统的规划布置有基础性意义。

Characteristic Analysis Through Drip Irrigation Under Mulch of Cotton in Saline-Alkali Areas of Xinjiang

According to the climate characteristic, soil structure, and water resources actuality of Xinjiang, the study was made on movement rule of water and salt, fertilizing kinds and fertilizing quantity, improving saline-alkali areas and using brackish water for drip irrigation, cotton yield and quality, soil heat environment through drip irrigation under mulch of cotton in saline-alkali areas. The results showed the application drip irrigation under mulch technology of cotton was of not only saving water, saving fertilization, saving energy, keeping entropy, improving saline-alkali areas, but also having economic benefits, social benefits and ecological benefits. To reasonably distribute of water resources and programming collocation of saving water irrigation system has fundamentally significance.
