Effects of Regulated Deficit Irrigation on Soil Water and Fruit Quality of Pear-jujube Tree in Greenhouse
摘要
Abstract
In order to investigate the effects of regulated deficit irrigation on water use efficiency and fruit quality of pear-jujube tree in greenhouse,nine-year-old pear-jujube trees in greenhouse were studied.The experimental treatments included the sufficient water supply during the whole growing period(treatment 1),moderate water deficits at the bud burst to leafing stage(treatment 2),high water deficits at the bud burst to leafing stage(treatment 3) and moderate water deficits at fruit growth stage(treatment 4).The results indicated that the different deficit irrigation levels at different growth periods had significant impact on the deep growth of root and evaporation among pear-jujube trees.Water deficits treatments at the stage of 2 and 3 had advanced the fruit quality of pear-jujube,stage 2 is better than stage 3.Water deficit during bud burst to leafing stage had deeply advanced the fruit quality and water use efficiency.It is the best stage to deficit irrigation.关键词
