摘　　要：水资源缺乏而农业用水量增加严重制约了我国农业生产的发展,节水灌溉是促进和保持农业可持续发展的重要途径。根据土壤水分运动的原理和作物灌水与土壤水分分布的特点,提出了一套温棚土壤湿度自动控制节水喷灌系统的设计方案,并设计了系统的主要技术参数。该系统符合我国农业生产实际特点,具有理论和实践指导意义。Lacking of water resource and increasing of agricultural using water limited the production of agriculture in China seriously. Under the circumstances, it is very important to irrigate by saving water in order to prompt and keep agricultural sustaining development. According to the principle about motion of soil water and the characteristic about distribution of soil water in irrigation, a design way of a spraying irrigation system to save water auto-controlled by moist degree of soil in greenhouse is developed, some main technology parameters are designed or given at the same time. The system was accord with the reality of agricultural production of our country and has directing meaning both in practice and theory.
