The integration of water and fertilizer is the development of agricultural standardization, informatization, large-scale and intensive.

China's existing 0.6 million hectares of irrigated area, is the basic traditional channel conveyance and surface irrigation mode, distribution of farmland water resources, irrigation and irrigation system controlled by manual work in the field, not only time-consuming, and serious waste and inefficient. In the mode of integration of water and fertilizer, water delivery pipeline, irrigation to achieve efficient irrigation by spray irrigation. The integration patterns of water and fertilizer can also be very convenient automatic monitoring soil moisture, the electromagnetic valve is equipped with automatic control, remote information transmission and other modern equipment, automatic control of irrigation and fertilization, increased with irrigation and fertilization uniformity, timeliness and convenience, and promote the standardization of agricultural production, information and intensive development.
