我省中部平原稻区,除了辽河上、中游部分地区有井灌条件外,其余全靠上游水库供水。1983年水库蓄水大大少于往年,水稻用水不足已成定局。为了压潮和减少输水损失,水利及农业部门已经决定,在水稻泡田插秧期将采取一次集中放水的办法。如能适当推迟泡田插秧期,缩短泡田插秧时间,不但可以减少蒸发、渗漏损失,而且能缩 In central plain plains of our province, except for the upper and middle parts of the Liaohe River, there are well irrigation conditions, while the rest rely solely on the upstream reservoirs for water supply. In 1983, the reservoir storage was much less than in previous years, and the shortage of water in rice was a foregone conclusion. In order to pressure the tide and reduce water losses, the water conservancy and agricultural sectors have decided that a centralized water diversion plan should be taken during paddy rice paddy planting. If we can properly delay the bubble soaked transplanting, shortening the time for planting soak, not only can reduce evaporation, leakage loss, and can shrink
