Abstract:: The study of soil desiccation in different growth years can provide the theory basis for improving the utilization on the gravel-sand mulched field in the arid zone of central Ningxia. Based on observation of soil moisture contents of fields with 3 years, 8 years, 12 years, 16 years and 25 years of gravel-sand mulch in the arid zone of central Ningxia, soil moisture contents, soil water overuse rate, soil desiccation indexes and thickness of desiccated were calculated, analyzed and compared. The Results showed as follows. Mean soil moisture contents, water storage and available soil water storage were 11.24%, 936.00 mm and 506.27 mm in the fields with the gravel-sand mulched under different years of growing watermelon. With the increase of growing years, soil moisture contents, water storage decreased gradually, soil water overuse rate increased gradually in the 0-600 cm soil layer. Soil moisture showed the overall trend that reduced first, then increased and gradually stable in the 0-600 cm soil layer in the fields with different growth years. The soil desiccation index ranged from 70.09% to 162.36%, the average thickness of the desiccated was 283.33 cm, presenting the moderate and mild drying intensities. The canonical correlation analysis showed that environmental factors such as latitude, longitude, growth years, silt and sand content were the significant factors affecting soil desiccation index and thickness of the desiccated layer.
