What is the concept of water and fertilizer integration, and what are the absolute advantages?

Agricultural planting is inseparable from irrigation and fertilization, we are a big agricultural country, has always been China's agricultural irrigation and fertilization are based on is dependent on the traditional way, for the integration of water and fertilizer equipment, I believe that many growers have heard of it, the main role of water and fertilizer integration equipment is used for rational irrigation and fertilization in planting, through reasonable irrigation and fertilization, effectively improve the growth environment of crops, so what are the benefits of using water and fertilizer integration equipment in planting? Let's find out about this!

The integrated irrigation equipment of water and fertilizer makes irrigation more reasonable, and the traditional irrigation is generally determined by experience, such as feeling that the crops in the field need to be irrigated, so turn on the irrigation equipment to irrigate the crops, or it is a fixed irrigation mode, such as irrigation once when the crops are just planted, and then irrigate again after a month or two months, such a fixed irrigation time, but such an irrigation mode is often irrigated in a timely manner, or the waste of irrigated water resources, The integrated irrigation equipment of water and fertilizer itself is determined by the data monitored by the sensor, and the soil moisture data can be monitored in real time through the soil moisture sensor, and when the moisture in the soil is monitored to be lower than the standard value, the system can automatically open the irrigation system to irrigate the crops! When the soil moisture reaches the standard value, the system can automatically turn off the irrigation system, and through such automatic control that can be relied on by data, the irrigation in your planting will be more reasonable!

In terms of fertilization, traditional fertilization and irrigation are not much different, and they are both based on experience or a fixed fertilization mode! Therefore, the disadvantages of such fertilization are also the same as irrigation, the integrated fertilization system of water and fertilizer is actually the same principle as irrigation, the nutrient data in the soil can be monitored in real time through the soil nitrogen, phosphorus and potassium sensor, when the nutrients in the soil are monitored to be lower than the standard value, the system can automatically open the fertilization system for crop irrigation, when the nutrients in the soil are monitored to reach the standard value, the system can automatically close the fertilization system, through such automatic control that data can be relied on, greatly improve the efficiency of planting!

The above is the introduction to the benefits and advantages of using water and fertilizer integration equipment, in fact, water and fertilizer integration equipment has been tried in many large agricultural planting bases many years ago, after several years of development, many functions of the system have been very perfect, the current water and fertilizer integration system has been able to achieve the docking of the mobile phone, through the mobile phone can understand the environmental elements of the plant in real time. It allows users to understand the environmental conditions of planting anytime and anywhere, and greatly improves the efficiency of planting!

The integration of water and fertilizer is the fertilization of the drip irrigation system, and the water and fertilizer integration of Netafim, the inventor of drip irrigation technology, is to dissolve the fertilizer and mix it with water through the fertilizer applicator and inject it into the drip irrigation pipe, and then directly transport the nutrients to the crop roots through the dripper, so that the plants can absorb and utilize the fertilizer faster and more accurately.

The biggest advantage of water and fertilizer integration: because of the characteristics of drip irrigation and slow feeding, most of the nutrients in the fertilizer can stay around the crop roots, and will not infiltrate to cause waste and groundwater pollution, which greatly improves the utilization rate of fertilizer.

Advantages of water and fertilizer integration technology: 1: water saving.

2: Improve fertilizer utilization. 3：

Reduce the amount of pesticides used. 4: Improve crop yield and quality.

5: Save irrigation and fertilization time and labor. 6：

Improve the soil microenvironment.

The operation law of soil water and fertilizer under micro-irrigation condition is very different from that under flood irrigation condition, and the theory and method of irrigation and fertilization have undergone revolutionary changes, becoming a new irrigation and fertilization technology. Its main characteristics are small flow, long time, high frequency, local sail number irrigation, and on-demand distribution.

This technology requires more equipment and a large one-time investment in the early stage; The requirements for management personnel are high, and professional training is required; Due to the short application time of this technology, there are few purchase channels for digital equipment and special fertilizers in the market; The long-term application of water and fertilizer integration technology may cause salt accumulation at the edge of the humid zone and cause a certain degree of root restriction effect on crops.

Israel Netafim invented the drip irrigation system in 1956, and on the basis of the drip irrigation system, the integration of water and fertilizer is a more water-saving, efficient and environmentally friendly irrigation method. The advantages of its water and fertilizer integration are:

Water and fertilizer saving:The integration of water and fertilizer can mix water and fertilizer and irrigate it into the roots of plants through the drip irrigation system to achieve precise irrigation, avoid wasting fertilizer, and avoid excessive water evaporation, so as to achieve the purpose of saving water resources.

Increase crop yieldsThe integration of water and fertilizer can provide crops with accurate and appropriate amount of water and nutrients, avoid the loss and fixation of nutrients in the soil, and avoid the growth obstacles caused by lack of water or too much water in the crop, thereby improving crop yields.

Reducing environmental pollution:Netafim's water and fertilizer integration can reduce environmental pollution caused by excessive fertilizer use, and at the same time avoid soil erosion and water pollution caused by fertilizer loss.

Reduced production costs:The integration of water and fertilizer can reduce the amount of fertilizer and water used, avoid the cost caused by the waste of fertilizer and water, reduce the input of labor, and improve production efficiency.

Now agriculture advocates the integration of water and fertilizer, and the stove is quickly selectedWater-soluble fertilizerBetter, water-soluble fertilizer to achieve water with fertilizer, high absorption and utilization rate, do not clog the filter and dripper, can save water, fertilizer dosage, improve crop growth, reduce diseases, etc.

Water-soluble fertilizer can be completely dissolved in water, containing a large number of micronutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, zinc, boron, etc., which are divided into two types: solid water-soluble fertilizer and liquid water-soluble fertilizer. From the nutrient content, there are a large number of elements of water-soluble fertilizer, medium hidden lead and this amount of element water-soluble fertilizer, trace element water-soluble fertilizer, amino acid-containing water-soluble fertilizer and so on.

Water-soluble fertilizer is widely used in modern agriculture and is suitable for all kinds of crops that need top dressing. However, when choosing, it is necessary to pay attention to the selection criteria of water-soluble fertilizer, such as good water-solubility, good fertilizer efficiency, and nutrient distribution ratio in line with the nutritional law of crops.

The integration of water and fertilizer is now vigorously promoted by the state, because the integration of water and fertilizer not only saves water and fertilizer, but also has a high utilization rate, but also ecologically teases and protects the environment. If you want to buy it, I strongly recommend the needle-shaped fertilizer, especially the instant needle-shaped fertilizer, such as the high-cost Novusch Western instant needle fertilizer. This is really good.

Not only for large-scale planting bases, but also for the surrounding farmers and friends, because of the high cost performance, 500-1000 yuan per ton cheaper than the general water-soluble fertilizer.

Differential pressure fertilization.

Fertilization scene in cotton field in Xinjiang (courtesy of Juguang Agrochemical).

Differential pressure fertilization method, through two thin pipes connected with the main pipe, a stop valve is set between the two thin pipe nodes on the main pipe, a pressure difference is generated, a part of the water flow is applied to the fertilizer tank, the water inlet pipe goes directly to the bottom of the tank, and after the fertilizer in the tank is dissolved in water, the water and fertilizer flow out from another thin pipe into the main water and fertilizer main pipe.

Schematic diagram of differential pressure fertilizer tank.

Merit. The equipment cost is low, the size is small, the operation is simple, and the maintenance is convenient. Liquid fertilizer and solid fertilizer can be directly poured into the tank for use, and it is convenient to use fertilizer.

Shortcoming. In the process of fertilization, the fertilizer concentration is not uniform or uniform, and it is easy to be affected by the size of water pressure, and the fertilizer concentration is high in the early stage and low in the later stage. The fertilizer tank is seriously corroded and has poor durability, and it needs to be poured many times each time the fertilizer is used in large amounts.

Venturi fertilization.

Venturi fertilizer applicator model.

The venturi fertilizer applicator is simple and consists mainly of jet tubes, which does not require additional power, and is widely used in the production of our country. When the water flows through a pipe that changes from large to small, and then from small to large, the flow velocity increases as the water passes through the narrow part, the pressure drops, and a negative pressure is formed between the atmospheric pressure, so that the fertilizer is sucked into the water pipe. Fight Book Round.

Merit. The equipment cost is low and the maintenance is simple. The concentration of fertilizer solution is uniform.

Shortcoming. The head pressure loss of the fertilization system is large. The greater the amount of fertilizer absorbed, the greater the pressure loss.

Relationship between pressure loss and fertilizer uptake in Venturi fertilizer applicator.

2.Solid fertilizer cannot be used directly, and fertilizer must be dissolved before use.

Fertilizer suction method before pumping.

Schematic diagram of the fertilizer suction method before pumping.

The pre-pump fertilizer suction method uses a centrifugal pump to directly suck the fertilizer solution into the irrigation system, and the principle of the method is relatively simple, using the water pump to suck the fertilizer water into the irrigation equipment at one time.

Merit. It does not need external power, the structure is simple and the operation is convenient. The fertilization rate can be controlled and the fertilization concentration can be adjusted.

Shortcoming. When the fertilizer is used up, the valve on the suction pipe needs to be closed, otherwise the air will enter the pipeline and affect the operation of the pump. The fertilizer needs to be dissolved well in the fertilizer pool, and the fertilizer inlet needs to have a filter to prevent blocking the pipeline.

Gravity self-pressure fertilization.

Gravity self-compression fertilizer applicator model.

Gravity self-pressure fertilization is more widely used in mountainous and hilly areas, and water and fertilizer are pressed into the fertilization pipeline through gravity.

Merit. Take advantage of the natural height difference to keep the liquid on its own, and only need to build a fertilizer pond or fertilizer tank at a higher position to apply fertilizer.

Shortcoming. The flow of water is not uniform, the flow rate at the low place is larger, the foundation collapse, and the flow rate at the high place is smaller. As a result, crops grow unevenly.

There is a better, scientific, economical and practical fertilization method, welcome to exchange.

1. The main technology of the integrated application of water and fertilizer: it is to automatically control irrigation and fertilization through sensors, soil moisture sensors to monitor the moisture in the soil, and automatically turn on the irrigation equipment when it is lower than the standard, and the same is true for the principle of fertilization, using soil nitrogen, phosphorus and potassium sensors to monitor the soil. Methods of integrated application of water and fertilizer:

It can provide sufficient nutrients for the nutrient critical period of fruit trees, and the integration of water and fertilizer can be used for water-soluble fertilizer spraying, as well as the practice of fertilization guns.

2. The integrated technology of water and fertilizer refers to the new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the soluble solid or liquid fertilizer with the fertilizer solution and irrigation water together with the soil nutrient content and the fertilizer demand law and characteristics of the crop type, and supply water and fertilizer through the controllable pipeline system, so that after the water and fertilizer are integrated, drip irrigation is formed through the pipeline and dripper, and the crop root development and growth area is infiltrated evenly, regularly and quantitatively, so that the main root soil always maintains loose and suitable water content; At the same time, according to the characteristics of fertilizer demand of different crops, soil environment and nutrient content, water demand of crops in different growth periods, and the law of fertilizer demand, the demand design of different growth periods is carried out, and the water and nutrients are regularly and quantitatively provided to crops in proportion.

The use of water and fertilizer integrated system irrigation and fertilization can make the fertilizer of crops more reasonable and uniform. Depending on the plant's fertilizer requirements and soil fertility sensors, nitrogen, phosphorus, potassium, etc. in the soil can be monitored. The proportion is automatically and manually set by the water and fertilizer machine to fertilize the crop reasonably.

The fertilizer utilization rate is higher, the phosphate fertilizer utilization rate is increased to 40% to 50%, the nitrogen fertilizer and potassium fertilizer are increased to more than 60%, and the crop nutrients are more comprehensive and efficient. Reduce unnecessary waste in Darby Fees. You can install the mobile application software in the integrated water and fertilizer system.

Irrigation and fertilizer can be managed remotely on a remote mobile phone. On the mobile phone, you can check the growth of crops and soil moisture anytime and anywhere. According to the data in reality, control the operation of the water and fertilizer machine, and water and fertilize the crops at any time.

In the traditional watering and fertilization project, a lot of manpower will be consumed. The use of water and fertilizer integration system can greatly reduce labor intensity. Greatly reduces labor costs and labor.

It also saves working hours. Proper watering and fertilization of planted crops through an integrated water and fertilizer system. It can accurately ensure that the moisture and fertilizer of the crop are sufficient, and the fertilizer required is sufficient.

On the premise that the water and fertilizer required for crop growth are sufficient and there are bad costs, the yield and quality of crop cultivation should be improved. The integration of water and fertilizer refers to the technology of dissolving fertilizer in water and spraying fertilizer and water on the leaves of crops at the same time through the irrigation system, or transporting them near the roots of crops to meet the needs of crops for water and fertilizer.

Floods erode and squeeze the soil, squeezing the air in the soil, killing roots and soil microorganisms due to lack of oxygen, destroying the structure of soil clumps and condensing soil plates. Through the integration of water and fertilizer, the compression effect on the soil is small, the air emission of the soil is less, and the harm to soil microorganisms is small, so the damage to the soil mass structure is small, and the soil compaction can be effectively prevented. The cultivated layer with soil of more than 30 cm has a large number of absorbing roots, and the temperature of the cultivated soil, drought, flooding, etc., can lead to the death of roots.

After the flooding, the surface air permeability, temperature, moisture content and so on change sharply, and the cultivated layer absorbs a large number of roots and dies quickly, which may lead to temporary nutrient absorption disorders of fruit trees. The integrated irrigation technology of water and fertilizer provides various nutrients and water to crops in a timely and appropriate amount, so that crops will not fall into drought, nutrients are sufficient, and their own resistance can be improved. At the same time, the application of water and fertilizer integration in plastic greenhouses can significantly reduce the humidity in the warehouse, reduce the occurrence of diseases, reduce the use of pesticides, and improve the quality of crops.
