The integration of water and fertilizer has been promoted for so many years, why has it not been wid

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 according to the soil nutrient content and the fertilizer demand and characteristics of the crop type, and the fertilizer liquid mixed together with the irrigation water is supplied with water and fertilizer through the pipeline system, and evenly and accurately transported to the root area of crops. <>

From the diagram, we can understand the operation process of water and fertilizer integration. Therefore, the integration of water and fertilizer requires the help of equipment, and has a certain suitable range, such as suitable for fixed water sources such as wells, reservoirs, reservoirs, etc., and the water source quality is qualified, which can be used for irrigation. In addition to this reason, the farmers did not approve of it, thinking that there were several other reasons.

The first is cognitive constraints. The vast majority of grain farmers lack knowledge and understanding of water and fertilizer integration technology, and their knowledge scope is limited, and their educational level is not high, making it difficult to accept and understand new technologies. The second is economic constraints.

The efficiency of farming is low, the income of farmers is not high, if you need to purchase and install equipment to use the integrated technology of water and fertilizer, the economic level of farmers may not allow the purchase of integrated water and fertilizer equipment. Moreover, more inputs are needed, which farmers do not think is cost-effective. The third is the restriction of farming methods.

The water pipeline belt affects each other with machine broadcasting and machine harvesting, and must be replaced once or twice a year. Fourth, scattered planting constraints. Due to the development of modern society, most of the farmers are elderly, and the planting area is not large, they feel that they can achieve self-sufficiency, and the planting area is much smaller than in the early years, resulting in the input-output ratio of the facility is not appropriate, and the farmers feel that there is no need to install it, and it can be completed by their hands.

Therefore, it is difficult for the integration of water and fertilizer to be widely recognized by farmers, and it is only used in some agricultural product bases or greenhouse vegetable planting areas. Normal farmers prefer to use the primitive way, and the planting can be done in the primitive way.

There are still many restrictions in the countryside, and the terrain and planting methods are not suitable for this, and the farmers do not understand these things, and they also have an attitude of opposition to these things.

I think that first, farmers are accustomed to using old-fashioned fertilizers, and on the other hand, farmers with integrated water and fertilizer feel that it is inconvenient to use!

Although this technology is very advanced, it is difficult to put it into practice when China's rural areas are not very developed.

A good harvest equals a bargain. Who has no brains to do this.

First, there is no technology, and second, there is no money to invest.

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.

Water and fertilizer integration technology.

Water and fertilizer integration technology.

The integration of water and fertilizer is a new concept of scientific application of water and fertilizer in the development of modern agriculture, and it is a new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer in the narrow sense is fertilization through an irrigation system, and crops absorb nutrients while absorbing water. Fertilization is usually carried out at the same time as irrigation, with the help of the pressure system (or the natural drop of the terrain), the soluble solid or liquid fertilizer, according to the soil nutrient content and the fertilizer demand of crop types, the fertilizer liquid is mixed with irrigation water, and then the water supply and fertilizer are supplied by the controllable pipeline system, so that after the water and fertilizer are integrated, drip irrigation, uniform, timing and quantitatively formed through the pipeline and dripper, infiltrate the crop root development and growth area, so that the main root soil always maintains loose and suitable water content. At the same time, according to the fertilizer demand characteristics of different vegetables, soil environment and nutrient content; Vegetables need water in different growth periods, and the demand for fertilizer is designed in different growth periods, and water and nutrients are regularly and quantitatively provided to crops in proportion.

Broadly speaking, it is to apply fertilizer after dissolving, including showering, watering, spraying, pipeline application, etc. At present, the commonly used water and fertilizer integration adopts the forms of sprinkler irrigation and micro-irrigation, and the commonly used form is the combination of micro-irrigation and fertilization, and the combination of drip irrigation, micro-spraying and fertilization is the majority. 1.

Scope of water and fertilizer integration technology The water and fertilizer integration technology is suitable for the promotion and application of areas with fixed water sources such as wells, reservoirs, reservoirs, etc., with good water quality, meeting the requirements of micro-irrigation, and where micro-irrigation facilities have been built or have the conditions to be constructed. It is especially suitable for the cultivation of field cash crops such as facility agriculture and orchards, as well as other crops with good economic benefits.

Generally speaking, it is about the agricultural irrigation and fertilization method of water and fertilizer applied to crops together through certain irrigation equipment, and its advantages are water-saving, fertilizer-saving, labor-saving, and teaching for agricultural production increase, which is the result of the development of agricultural modernization.

The integration of water and fertilizer refers to the new agricultural technology that integrates irrigation and fertilizer. The integration of water and fertilizer is a new agricultural technology that mixes fertilizer and water evenly with the help of a pressure system, and sprays water and fertilizer through irrigation (drip irrigation). At present, the main integration of water and fertilizer is the phase and seedling fertilizer, balance fertilizer, and fruit expansion fertilizer @ subtle legion.

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.

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.

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.

The investment in the integration of water and fertilizer is relatively high, but the application in paddy fields can bring significant economic and environmental benefits.

The integration of water and fertilizer refers to the organic combination of irrigation and fertilization and other agricultural management activities, through refined and intelligent management methods, to achieve efficient utilization of water and fertilizer resources and reduce the discharge of pollutants such as pesticides and fertilizers. The application of water and fertilizer integration technology in paddy fields can make full use of water and fertilizer resources, improve fertilizer utilization rate, reduce the use of pesticides and chemical fertilizers, improve soil quality and microbial community, and thus increase the yield, quality and economic benefits of paddy fields. However, the integrated technology of water and fertilizer requires relatively high costs, including investment in equipment, manpower, technology and other aspects.

In the process of promoting the integration of water and fertilizer technology, it is necessary to formulate corresponding technical solutions and management mechanisms for different regions, different crops and different planting patterns, so as to ensure the effective application and operation of the technology.

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!
