Water and fertilizer integration technology is a new agricultural technology that integrates watering and fertilization. It has the characteristics of saving fertilizer and water, saving labor and labor, saving time and electricity, and increasing production efficiency. Compared with traditional flood irrigation, it can save more than 30% of water, 30%-50% of fertilizer, labor cost by about 70%, water and fertilizer utilization rate of more than 90%, and large-scale application and application will be considerable. Economic and social benefits.
Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. Water and fertilizer integration is based on the pressure system (or natural topography), the soluble solid or liquid fertilizer, according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, together with the fertilizer solution and irrigation water.
Through the water supply and fertilizer supply of the controllable pipeline system, the water and fertilizer are blended, and drip irrigation, uniformity, timing and quantification are formed through the pipeline and the dripper to infiltrate the root growth and growth area of the crop, so that the main root soil always maintains a loose and suitable water content. At the same time, according to the characteristics of fertilizers, soil environment and nutrient content of different crops; the demand for water in different growth periods of crops, the demand for fertilizers, and the design of different growth stages, the water and nutrients are regularly quantified and directly supplied to the crops in proportion.
Water and fertilizer integration scope
The technology is suitable for fixed water sources such as wells, reservoirs, reservoirs, etc., and has good water quality, meets micro-irrigation requirements, and has been built or conditionally built for the promotion and application of micro-irrigation facilities. It is mainly suitable for cultivation of large-scale economic crops such as facility agriculture cultivation, orchard cultivation and cotton, as well as other crops with good economic benefits.
