辽河下游平原区淹灌条件下水稻的需水规律研究

下辽河平原的台安地区,水田灌溉用水量,约占农业灌溉用水总量的80%左右。在灌溉用水量中,只有水稻的叶面蒸腾量才是灌溉的有效水量,只有这部分水量被水稻所吸收,其余水量都是损失量。因此水稻叶面蒸腾量的确定对水稻的节水灌溉、对实现水稻生产的可持续发展和农业水资源的可持续利用具有重要的意义,节水灌溉的社会效益、经济效益和环境效益都十分巨大。

The research for the water demand regulation of rice under ponding in Lower Liaohe Plain

The paddy field irrigation water in Tai'an district of lower Liaohe Plain accounts for about 80% of total agricultural irrigation water.In irrigation water,only the amount of transpiration of rice leaves is effective irrigation water,which has been absorbed by rice and the remaining amount of water are lost.Therefore,the determination of the amount of rice leaf transpiration is significance for social,economic and environment benefit to achieve water-saving irrigation of rice,rice production sustainable dev...
