水是生物生存之源,是农林业生产发展的必要条件,肥料是农业增产高产的重要保障。近年来,随着人口增长,工业化、城镇化进程的加速,我国耕地减少、水资源匮乏等资源约束日益趋紧,与此同时,大水漫灌、过量施肥现象还比较普遍,因此迫切需要一种能够节水、省肥、提高设施蔬菜产量和品质、保护生态环境的新技术,来解决干旱缺水、水肥利用率低和土壤盐渍化问题。水肥一体化技术是将可溶性肥料与灌溉
Water is the source of biological survival and the necessary condition for the development of agriculture and forestry production. Fertilizer is an important guarantee for the agricultural yield and high yield. In recent years, with population growth, industrialization and urbanization accelerating, resource constraints such as the reduction of arable land and water scarcity in China have become increasingly tighter. At the same time, flood and overflooding is still common, and there is an urgent need for a It can solve the problems of drought and water shortage, low utilization rate of water and fertilizer, and soil salinization, which can save water, save fertilizer, improve vegetable yield and quality in facilities and protect ecological environment. Integrated water and fertilizer technology will be soluble fertilizer and irrigation
