摘要
控水灌溉技术有效地调控土壤水分状况，增强土壤水分效应是节水高产的重要因素之一。提出了全年节水吨粮的主要外部环境条件和灌排调控技术参数及其对水稻的生理效应。这一试验结果为南方类似地区实现节水吨粮持续发展的灌排技术指标提供了依据。
Adopting the controlling irrigation techniqne to strengthen the soil moisture effectiveness is an important approach to the water saving and ton yielding of grain per mu.the main environmental conditions of water saving ton yielding of grain and techniqne parameters of irrigation drainage regulation control as well as its physiological effect on rice are presented.
