Abstract: According to needs of large-scale strawberry planting in facility park for improvement of water and fertilizer management model and level，based on construction of intelligent water and fertilizer integration system，planting experiment was carried out in strawberry irrigation and fertilization link of 23 solar greenhouses in the park.Compared with traditional venturi fertilizer absorber technology，result showed that intelligent water and fertilizer integration system in facility park had definite advantages.It improved labor productivity by 12 times and significantly reduced labor intensity.It realized precise regulation of irrigation and fertilization，reduced fertilizer dumping and waste，and had certain ecological benefits.It guaranteed stability of strawberry yield and quality，and strawberry yield increased by 1.7% in this experiment.Economic benefits of pilot park increased by 26 037 yuan/hm2.The result of this experiment provided a reference for construction of intelligent water and fertilizer integration systems and economic benefit calculation in majority of facility parks.
