Abstract:
Limonium aureum was used as experimental material,the effect of the different irrigation quota on the biomass of Limonium aureum was studied under the six total irrigation treatments（0.5,10,15,20,25,30 mm),with the treatment of 0 mm irrigation as control.The results showed that,1)With the increasing irrigation quota,the density of Limonium aureum increased firstly and then decreased.2)The aboveground fresh and dry weight of Limonium aureum both reached the lowest point under the 10 mm irrigation treatment,and reached the highest point under the 20 mm irrigation treatment,and the water content of aboveground showed an increased trend on the whole.3)The fresh weight of underground reached the highest point under the 25 mm irrigation treatment,which was significantly higher than the control and the other irrigation treatments.The dry weight of underground under the 15,20,25 mm irrigation treatment was significantly higher than the 10 mm irrigation treatment and control.4)Under the high irrigation quota treatment（25 mm and 30 mm),there were significant differences between the plant height and canopy with the control.
