以农田水位作为水稻灌排指标的研究进展

通过对水稻生长期稻田水分变化的定性分析以及现行水稻灌排调控指标的分析研究,认为水稻的旱、渍、涝与农田水位密切相关,水稻的灌溉排水问题就是农田水位的调控问题。提出了以农田水位作为水稻灌排调控指标的研究框架,设计了研究内容和技术路线,研究成果从理论上证明农田水位可以作为水稻灌排的调控指标,进而形成了水稻灌排的农田水位调控指标体系,丰富水稻高效灌排理论。

Research Advance on Irrigation-drainage for Rice by Using Field Water Level as Regulation Index

Based on qualitative analysis of paddy moisture content variety during growing period and present paddy irrigation-drainage control index,considered that there are close relationship between droughts,waterlogging,floods of rice and field water level,the key problem of paddy irrigation-drainage is water level control.Research scheme of take water level as control index of paddy irrigation-drainage had been pointed out.Research content and technical method had been designed,in theory,expected achievements was proved that water level can be as control index of paddy irrigation-drainage,and then formed water level control index system of paddy irrigation-drainage,enrich the theory of high efficiency irrigation-drainage for rice.
