[0002] Water-fertilizer irrigation is the process of applying fertilizer through an irrigation system. Crops absorb nutrients while absorbing water. Water-fertilizer integration is a new agricultural technology that combines irrigation and fertilization. It is a process of mixing soluble solids into fertilizer liquid, which is mixed with irrigation water and then used to form drip irrigation through pipes and drippers through a controllable pipe system to evenly, regularly, and quantitatively infiltrate the crop root development and growth area.
