Abstract:: Taking tomato as test material,the effects of different water and fertilizer management on tomato growth,yield and economic benefit of the facilities were studied.The results showed that the integration of water and fertilizer had obvious advantages in improving tomato yield,water,fertilizer and labor aspects.The yield of tomato was guaranteed and increased,the yield increased by 16.22%.Water use efficiency increased by 33.21%,water saving rate of 21.89%；saved up to 39.50% with fertilizer；laborsaving was 12.20%.Drip fertilization significantly decreased the air humidity in the greenhouse than irrigation fertilization.It was to reduce the occurrence of pests and diseases.Drip fertilization and pesticide dosage the pesticide dosage of drip fertilization decreased by 21.05%.
