Water & Fertilizer
Core functions
Soil moisture monitoring
To guide farm irrigation and agricultural drought mitigation and to determine the timing and amount of irrigation based on soil moisture deficit in order to avoid over-irrigation and improve water use efficiency.
Intelligent Water and Fertiliser Control
According to the crop growth prediction model, through the intelligent control management of the water and fertilizer integration system, the implementation of regular and quantitative irrigation and fertilization, precision planting, maximizing agricultural productivity and achieving high-quality, high-yielding and environmentally sustainable agriculture.
Agricultural Internet of Things Platform
Combining IoT, big data and mobile connectivity, the smart agriculture solution supports computer and mobile applets, which can remotely measure and remotely monitor air, temperature and other crop growth environments in real time, and provide manual and intelligent control of control equipment, early warning functions, live streaming, control and capture of video, which helps to precisely control production cycles, reduce manpower and material inputs, and improve crop quality and yield.
Advantages of water and fertilizer technology
Compared with traditional irrigation and fertilization measures: water and fertilizer machine technology can improve the utilization rate of water and fertilizer, to ensure a balanced supply of water and nutrients to each crop, thus saving water and fertilizer, reducing the amount of pesticides and making agricultural products safer. In the case of grapes, for example, the use of water and fertiliser requires 5-10m³/mu of water, saving 30%-40% of water compared to traditional diffuser irrigation;
Water and fertiliser implementation programme
Water and fertiliser is a comprehensive technology, involving farm irrigation, crop cultivation and soil cultivation, etc. Its main technical elements must be noted in the following four aspects.
1. Establish a drip irrigation system
In terms of design, the depth, length and area of the irrigation area of the pipeline system should be designed according to the basic conditions of the terrain, field, unit, soil texture, crop cultivation method and water source characteristics. Water and fertiliser irrigation can be done by pipe irrigation, sprinkler irrigation, micro-spray irrigation, pump pressurised drip irrigation, gravity drip irrigation, percolation irrigation, small pipe outflow, etc. Especially avoid using large water irrigation, which is easy to cause nitrogen loss, but also reduce the water utilization rate.
2. Fertiliser application system
In the field to be designed for quantitative fertilisation, including the location, capacity, outlet, fertiliser pipeline, distributor valve, pump fertiliser pump, etc. of the reservoir and mixing pool.
3. Operation of irrigation fertilisation
Fertiliser dissolution and mixing: no stirring or mixing is required when applying liquid fertiliser, generally solid fertiliser needs to be mixed with water and stirred into liquid fertiliser and separated if necessary to avoid problems such as sedimentation.
4. Fertiliser volume control: the dose should be mastered when applying fertiliser, and the appropriate concentration for injecting fertiliser is approximately 0.1% of the irrigation flow. For example, if the irrigation flow rate is 50m³/acre, the fertilizer solution injected is about 50 litres/acre; excessive application may kill the crop and pollute the environment.
The irrigation and fertiliser application procedure is divided into 3 stages: in the first stage, fertiliser-free water is used to wet the crop; in the second stage, the crop is irrigated with the fertiliser solution; and in the third stage, the irrigation system is cleaned with fertiliser-free water.
The effect of using water and fertiliser in one machine
1. Uniformity of water and fertiliser
The traditional way of watering and fertilising is to starve the crop for a few days and then hold it for a few days, without being able to "eat and drink" evenly. The use of scientific irrigation, according to the crop needs water and fertilizer law at any time supply, to ensure that the crop "eat comfortable, drink painful"!
2. Save labour and time
Traditional furrow irrigation and fertiliser application is time consuming and very troublesome. With drip irrigation, all you need to do is open the valve and close the electric gate, hardly any work is required.
3. Save water and fertiliser
The drip irrigation belt directly transports the fertiliser needed by the crop to the roots of the plant evenly with the water, so that the crop "drinks slowly", which greatly improves the utilisation rate of fertiliser and reduces the amount of fertiliser by 50%.
4. Reduce diseases
Many diseases in greenhouses are soil-borne and spread with the flow of water. Such as pepper blight, tomato blight, etc., the use of 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.
5. Temperature and humidity control
The use of drip irrigation in winter can control the amount of watering, reduce humidity and increase the ground temperature. Traditional furrow irrigation can cause soil caking and poor permeability, leaving the crop roots in a state of oxygen deprivation, resulting in root composting, while using drip irrigation avoids problems such as root composting and yellow leaves caused by excessive watering.
6. Increase yield, improve quality and increase economic efficiency
Water and fertilizer machine future development prospects
When water fertilizer machine irrigation water, we should adhere to the water management and scientific scheduling according to the law, and crack down on water theft, water grabbing and other acts. Maintain the order of water use and the legal right to use water, and create a good environment for the irrigation area. After the end of the irrigation period, carry out timely data compilation, flow monitoring and dispatching situation analysis, calculate the water utilisation coefficient of each canal system, and carry out reward and penalty assessment. At the same time, the problems of irrigation are carefully analysed and countermeasures are proposed to improve the efficiency of water utilisation in irrigation.

The staff concerned have a certain level of political quality and high business ability. Dispatch staff understand the basic situation of the system, such as unit configuration, outflow capacity, location of water intake and water transmission capacity. In recent years water allocation in irrigation districts has achieved significant results, meeting agricultural water use during critical water demand periods, improving water use efficiency, expanding the market for water use and achieving a win-win situation in terms of water savings and increased production.
