Silicon (Si) is used to alleviate abiotic stress in plants. Applying siliceous fertilizer in combination with regulated deficit irrigation may reduce water consumption during plant vegetative growth period. In this study, winter squash ‘East Elite’ was irrigated with 0.5, 1.0, and 1.5 mM SiO2 under a field capacity—that is, the water content of 60% (C60, water-saving irrigation). The SiO2 treatments promoted plant growth including stem diameter, plant height and leaf number; however, the plant growth under water-saving irrigation was slightly (but significantly) lower than that under regular irrigation (C80). Silicon application in the water-saving irrigation can increase the accumulation of fresh and dry weight in the aboveground and underground of plant, but there is no significant difference between the treatments with different concentrations of silicon. Silicon application treatments was significantly higher chlorophyll content (SPAD) than C60, and followed by C80. The SiO2 in the plants increased with increasing SiO2 treatment concentration; however, the difference was nonsignificant. The 1.0 and 1.5 mM treatments increased the leaf transpiration rate and stomatal conductance. The growth of the plants treated with 1.5 mM SiO2 was greater than that of the plants left untreated. The 1.5 mM SiO2 treatment increased the activity of leaf catalase and peroxidase and reduced the leaf malondialdehyde content of the mild water stressed plants. Irrigation with a SiO2 solution in a water-saving irrigation system can stabilize plant growth and increase water use efficiency.
