Water-fertilizer integrated technology is a new agricultural technology that integrates irrigation and fertilization. Water-fertilizer integration uses a pressure system (or natural terrain drop) to deliver soluble solid or liquid fertilizers, formulated according to soil nutrient content and crop nutrient requirements and characteristics, along with irrigation water,

Water-fertilizer integrated technology is a comprehensive water and fertilizer management measure in modern agricultural production, with significant advantages in water saving, fertilizer saving, labor saving, high quality, high efficiency, and environmental protection. Water-fertilizer integration is a new irrigation method that combines irrigation and fertilization. The fertilizer itself will not flow through the pipeline and must be dissolved in water to flow through the pipeline, which is easy to distinguish from traditional fertilization. According to the specific irrigation form, it can also be called "drip irrigation fertilization", "sprinkler irrigation fertilization", etc. I. Theoretical basis of water-fertilizer integrated irrigation The transpiration of plants and ground evaporation cause crops and soil to lose a lot of water, so to ensure the normal growth of crops, a continuous supply of water is necessary.

The basic concept of water and fertilizer integration technology is that the goal of crop production is to obtain higher yields, better quality, and higher economic benefits at lower production costs. From the perspective of crop growth elements, the basic growth elements include light, temperature, air, water, and nutrients. Under natural growth conditions, the first three factors are difficult to control artificially, while water and nutrient factors can be artificially controlled. Therefore, in order to realize the greater production potential of crops, it is very important to reasonably adjust the balanced supply of water and fertilizer. Intelligent water and fertilizer integration technology is mainly based on irrigation equipment and fertilization equipment, and the formula is mixed with water and fertilizer and transported to crops. The system composition of intelligent water and fertilizer integration technology. The use of water and fertilizer integrated machines improves water and fertilizer. Compared with traditional field irrigation methods, intelligent water and fertilizer integration technology uses drip irrigation technology to evenly deliver fertilizer liquid to crops. According to relevant experimental data: water use efficiency comprehensive fertilization method, water use efficiency is increased by 40%~60%, compared with traditional large flood irrigation, saving labor and labor costs, and is conducive to large-scale planting. Water and fertilizer integration technology is an advanced and practical technology that saves costs and increases efficiency. In areas with conditions, as long as the initial investment is solved and there is technological support, its promotion and application will become an effective measure to increase farmers' income. Saving fertilizer and water, saving labor and effort, reducing humidity, reducing diseases, increasing yield and efficiency; traditional watering and topdressing methods, crops starve for a few days and then support for a few days, unable to "eat and drink" evenly. Using scientific irrigation methods can provide water and fertilizer according to the law of crop needs at any time, ensuring that crops "eat comfortably and drink happily"!
