Water and fertilizer integration is the use of pipeline irrigation system, the fertilizer is dissolved in water, irrigation, and fertilization at the same time, timely and appropriate to meet the demand for water and nutrients of crops, water and fertilizer synchronous management and efficient use of water-saving agricultural technology, with the help of pressure system Or the natural drop of the terrain, the soluble solid or liquid fertilizer, according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, the fertilizer solution is mixed with the irrigation water. Through the water supply and fertilizer supply of the controllable pipeline system, the water and fertilizer are merged, and the micro-irrigation, uniformity, timing, and quantification are formed through the pipeline and the dripper to infiltrate the root growth and growth area of the crop.

Water and fertilizer integrated drip irrigation technology consists of irrigation first (water pump, power machine, filtration equipment, fertilization system, control valve, etc.), water distribution network (including dry pipe, branch pipe, capillary three-stage pipeline), emitter (divided into dripper, drip irrigation) Tube, etc.) and flow, pressure control components and measuring instruments. The fertilization system includes a venturi fertilizer, a fertilizer pump, a fertilization tank, and a smart fertilization system. Commonly used filtration systems include mesh filters and laminated filters. The water source with a lot of sand needs to be equipped with a centrifugal filter, and the water source containing moss or debris is required to be equipped with a media filter.
In fact, the growth of crops is inseparable from the resources of soil, water, fertilizer, etc. The ability to use these resources efficiently is related to the sustainable development of agriculture. Compared with the traditional model, the integration of water and fertilizer has realized a revolutionary transformation of water and fertilizer management, that is, the conversion of channel water to pipeline water, the conversion of watering to pouring crops, the fertilization of soil fertilization to crops, and the separation of water and fertilizer into water and fertilizer. Therefore, some experts pointed out that water and fertilizer integration technology is a major technology for developing high-yield, high-quality, high-efficiency, ecological and safe modern agriculture, and an important way to develop modern agriculture.
Water and fertilizer average
It can be supplied at any time according to the requirements of crops requiring water and fertilizer to ensure balanced crop absorption!
Water-saving and fertilizer saving
The integration of drip irrigation and water and fertilizer directly transports the fertilizer needed by the crop to the root of the plant evenly, which greatly improves the utilization rate of the fertilizer, and can reduce the amount of fertilizer by about half. The water volume is only 30%-40% of the furrow irrigation. about.
Save time and labor
The traditional ditch irrigation and fertilization costs are very troublesome. With drip irrigation, just open the valve and close the switch, almost no work.
Prevent the occurrence of pests and diseases
Many diseases in the greenhouse are caused by soil-borne diseases and spread with running water. Such as pepper blight, tomato blight, etc., drip irrigation can directly and effectively control the occurrence of soil-borne diseases. Drip irrigation can reduce the humidity in the shed and reduce the occurrence of diseases.
Temperature control and humidity control
Drip irrigation in winter can control the amount of water, reduce humidity and increase ground temperature. The traditional furrow irrigation will cause soil compaction and poor permeability. The root system of the crop is in the anoxic state, causing the rooting phenomenon. The use of drip irrigation avoids problems such as crop roots and yellow leaves caused by excessive watering.
