寒地水稻超稀植节水高产灌溉制度及其需水规律的试验研究

Studies on the Irrigation System and Water Consumption Pattern of Ultraspare Planting Practice of Rice in the Water-Saving Irrigation Models in Cold Region

本文通过水稻超稀植栽培不同灌溉制度与灌水、田间需水量关系，不同灌溉制度对产量的关系，不同水层对温度的影响和超稀植水稻的需水规律等方面试验研究分析，明确了寒地水稻超稀植栽培的最优灌溉制度和超稀植水稻的需水规律，为应用水稻超稀植栽培的节水高产灌水技术提供了依据。

Through the relationship between irrigation and water consumption in paddy field and the effect of irrigation system on yield in ultraspare planting practice of rice, we ascertained the best Suitable irrigation system and water consumption pattern,which provided scientific basis for high yield of water-saving irrigation technique.
