Integration of water and fertilizer

The technology of integration of water and fertilizer refers to the new agricultural technology integrating irrigation with fertilization. With the help of the pressure system, the integration of water and fertilizer uses the fertile solution mixing soluble solid or liquid fertilizer according to the law and characteristics of soil nutrient content and crop species with irrigation water to supply water and fertilizer through the controllable pipeline system. After the integration of water and fertilizer, the pipes and water droppers are formed into drop irrigation to evenly, regularly, and quantitatively infiltrate the crop root development and growth area and keep the main root soil loose and suitable water content all the time. Meanwhile, the demand of different growth periods is designed according to the characteristics of fertilizer demands of different crops, the status of the soil environment and nutrient content, the water demands of different growth periods, and the law of fertilizer demand to provide the water and nutrients directly to the crops in proportion.
