Drip irrigation and integration of water and fertilizer technology of rice dryland cultivation

With agricultural modernization rapid advancement and increasingly prominent contradiction between water resources supply and demand, rice field management mode is facing transitioning development requirements to automation, mechanization, and water and fertilizer saving．To meet modern agriculture development needs, rice dryland cultivation technology has been promoted and applied on a large scale．Aiming at immature field management technology, extensive water and fertilizer management mode, and low automation degree and other problems in current rice dryland cultivation technology．Research on rice dryland cultivation water, fertilizer and pesticide management technology was carried out through field experiments to form a drip irrigation and integration of water and fertilizer technology management model suitable for rice dryland cultivation．Results showed that dryland rice yield was 7261.50 kg/hm², irrigation water in whole growth period was 12750 m³/hm², which was equivalent to paddy field cultivation water consumption and yield．However, drip irrigation and integration of water andfertilizer technology effectively improved field management mechanization degree and water and fertilizer utilization rate, which met modern agriculture development needs．
