Effects of drip irrigation on the growth and yield of strawberries were studied inside a plastic greenhouse. The amounts of irrigation water applied were 0·75, 1·00 and 1·25 times water surface evaporation (Ep) measured by a standard 200mm diameter pan, and the corresponding regimes were denoted Ep0·75, Ep1·00 and Ep1·25. During the experimental period, soil moisture tension of regimes Ep1·00 and Ep1·25 at 0·2m depth varied from 5 to 17kPa, and varied from 5 to 23kPa at 0·4m depth; but soil moisture tension of regime Ep0·75 at 0·2m depth changed from 6·5 to 43kPa, and soil moisture tension at 0·4m depth had been over 70kPa at the end. Plant leaves, flowers and fruits, above-ground biomass, runners, total berry yields, marketable strawberry yields (>5g), the size of strawberry fruits all increased when the amount of irrigation water increased from Ep0·75, Ep1·00 to Ep1·25. Irrigated water increased …
