井灌水稻池内水温分布规律与灌水方法的研究

Research on temperature distribute regulation of well water-irrigated paddy and irrigation methods

井灌水稻池内温度分布特征是靠近进水口处形成一低温区 ;灌水过程中温度变化是一个降温过程 ,停止灌水后水温迅速上升 ;采用单排单灌、间歇灌水、并且更换进水口的灌水方法 ,有利于降低因灌水造成池口附近低温区的不利影响 ;

The temperature distribute regulation of well water irrigated paddy is that there was a low temperature area near the entrance.Temperature of the water in the paddy decreased while irrigating and increased rapidly after finish. Irrigatied the paddies one by one,irrigeated discontinuously and changed the entrance were favorable for minimizing the disadvantage of low temperature near the entrance caused by irrigation.Increased water supply in daytime was adoptable for ear protection water administration.$$$$
