Abstract: 【Objective】 The objective of this study was to investigate the effects of different drip irrigation time on the patterns of soil water movement in yellow red soil for 1 year in Cinnamomum camphora plantation under drip irrigation in Yuhang, Zhejiang Province in a subtropical region.【Method】 We measured the movement process of the soil wetting front, soil volumetic water content(SVWC), and the shape of the wetting soil after stopping drip irrigation by observing the soil profile in the field and analyzing soil moisture sensor data with a constant flow rate of 2 L/h.【Result】①The advancing rate of the soil wetting front in both horizontal and vertical directions had an extremely significant power function relationship with infiltration time from continuous drip irrigation of 1-6 h, and the R² values were all above 0.97, and the final movement distance of the soil wetting front for different drip irrigation time in the horizontal direction in various soil levels all were on the surface of the soil. ② Movement duration of the soil wetting front after stopping different drip irrigation time were 1-2 h, and the shape of the wetting soil was similar to that of the hypothesized conicalness into a vertical semi-ellipsoid. ③During continuous drip irrigation of 6 h, the changing process of SVWC at various testing locations at both 20 and 40 cm was monitored. Water had a tendency of rapidly increasing, then slowly increasing, and finally remaining stable after drip irrigation of 1.5, 3.0, 6.0 h, respectively. The SVWC increased over levels of the field water capacity(FWC)at testing locations of 0, 20 and 30 cm from the point source horizontally in soil at 20 cm depth, after drip irrigation of 2.0 and 4.0 h, respectively. The SVWC increased over levels of the FWC at testing locations of 0 and 20 cm from the point source horizontally in soil at 40 cm depth, and the SVWC remained over 70% FWC in 48 h after stopping irrigation at various testing locations at both 20 and 40 cm.【Conclusion】Based on the study of the Cinnamomum camphora plantation under drip irrigation, the flow rate of 2 L/h was reasonable, and the drop of space designed to 40 cm was better. For planting container seedlings, drip irrigation of 2-3 h is needed in the early rooting period and 4-5 h in the late growing period. Irrigation should be timely and adequate to assure stand growth needs.
