Fig. 8

Effect of different spring irrigation treatments on cotton plant height, stem diameter, and leaf area index. Figures 8a, 8b, and 8c are the dynamic trends of plant height, stem diameter and leaf area index with time, respectively. FS is freshwater spring irrigation, MFS is magnetized freshwater spring irrigation, BS is brackish water spring irrigation, and MBS is magnetized brackish water spring irrigation. Data are mean value of the five replicates. Error bars mean standard errors. Differences were determined using Duncan’s multiple range test. Different letters above the bars indicate significant differences among treatments at p < 0.05
