The invention provides a fertilizer and water management irrigation method for tomato growth. According to the method, the fertilizing amount, soil moisture content and irrigation volume at all the stages of tomato growth are controlled; and the stages of tomato growth comprise the seedling stage, the flowering and fruit bearing stage and the fruit mature stage. The method is suitable for tomato fertilizer and water integrated irrigation of facility cultivation. Compared with a tomato fertilizer and water formula currently used in production, it is discovered that the production cost can be reduced by 12.5%, and the total output is increased by 10.6%.
