Abstract：Taking random sampling and field questionnaire forms，this paper carried out investigation and analysis in 2018 on 643 vegetable farmers from Fuzhou，Xiamen，Putian，Quanzhou，Zhangzhou，Longyan，Sanming，Nanping，Ningde 9 cities in Fujian Province about water-fertilizer integration allocation and current situation of application in vegetable production．The results showed that the main type of vegetable production in Fujian Province was open field cultivation，followed by small arch shed and simple greenhouse cultivation，accounting for 38.10%，33.12% and 24.88% of the total household number investigated，respectively．Vegetable farmers using water-fertilizer integration technology occupied 77.60% of the total household number investigated．The main water outlet mode of water-fertilizer integration was under film sprinkler irrigation，accounting for 42.08%，mainly applied to small arch shed and simple greenhouse．Fertilizer injection modes were mainly pump injection and pump suction，accounting for 34.87% and 29.86%，respectively．These modes were mainly applied to small arch shed，simple greenhouse and open fields．The water-fertilizer integration and filtration system were mainly manual operation，occupying 67.33% and 75.95%，respectively，generally with lower degree of automation．Under the condition of similar yield，the application of water-fertilizer integration could reduce the amount of nitrogen fertilizer about 17%，of phosphorus fertilizer about 9%，and of potassium fertilizer about 14%．Compared with conventional fertilization，the application of water-fertilizer integration could increase the yield by 21.99%-29.90%，and economic benefit by 32.12%-50.80%．
