Abstract: The effects of soil moisture on the plant growth , yields , physical and chemical properties of strawberry fruit were studied by use of a new auto-irrigation systemof negative pressure. It was showed that plant height , number of leaves , fruit weight , fruit diameter , fruit number and yields gradually decreased with the decreasing of soil moisture. The physical and chemical properties were apparently different under different soil moisture treatments. The Deficit Irrigation decreased water content of fruit , increased fruit hardness , soluble solid content , titratable acidity , sugar-acid
ratio and the content of ascorbic acid. The correlation analysis indicated that soil moisture has a positive correlation with the fruit diameter and weight , but has a negative correlation with soluble solid content and sugar-acid ratio.

Key words: Strawberry, Soil moisture, Plant growth, Fruit, Properties
