试验初步探讨了井灌水稻晒水池及灌水渠道的增温作用 :晒水池的增温作用与其面积密切相关 ,面积越大增温效果越明显 ,晒水池中约 1/ 3的面积对于增温作用较大 ;灌水渠道也有明显的增温作用 ,渠道越长增温作用越强 ,但断面流量大影响增温效果 ;晒水池、渠道的增温动态与气温变化规律相一致 ,白天的增温作用明显大于夜间 The experiment initially explores the warming effect of well irrigation basins and irrigation channels: the warming effect of basins is closely related to their area, and the larger the area is, the more obvious the warming effect is. The area of ​​about 1/3 in the basins is more important for warming Large irrigation channels also have a significant warming effect, the longer the channel, the stronger the warming effect, but the large cross-section flow affect the warming effect; basins, channels and the temperature changes in the dynamic trends consistent with the daytime warming obvious More than night
