水稻优化灌溉技术是在浅湿灌溉研究基础上,应用模糊理论,非饱和土壤水理论和土—植—气连续系统原理,对土壤水分调节与产量关系进行定量分析,将经验灌溉模式上升到优化灌溉模式,得出的一套因土、因苗、因时制宜,浅湿干灵活调节,促控养结合的灌溉技术,它是浅湿灌溉的发展和深化,因此更加完善,具有更 Based on the research of shallow wet irrigation, the optimized irrigation technology of rice is based on fuzzy theory, unsaturated soil water theory and the principle of soil-plant-gas continuous system. Quantitative analysis of the relationship between soil moisture regulation and yield increases the experience irrigation mode to optimization Irrigation mode, derived from a set of soil, because of seedlings, due to the time, shallow wet and dry flexible regulation, and promote the combination of irrigation control technology, it is shallow wet irrigation development and deepen, so more perfect, with more
