What do you know about the introduction of sprinkler irrigation technology and the three elements of

Sprinkler irrigation is to send the pressurized water formed by the water pump or natural drop to the field through the pressure pipeline, and then spray it into the air through the sprinkler head to form fine water droplets, which are evenly sprinkled on the farmland to achieve the purpose of irrigation. Generally speaking, its obvious advantages are uniform irrigation, less occupation of arable land, saving manpower, and strong adaptability to terrain. The main disadvantage is that it is greatly affected by the wind and the equipment investment is high.

After more than 20 years of efforts, China now has more than 800,000 hectares of sprinkler irrigation. There are many forms of sprinkler irrigation systems, and their advantages and disadvantages vary greatly.

What do you know about the three technical elements of sprinkler irrigation?

Now that the technology is developed, sprinkler irrigation technology is also widely used, what do you know about the three elements of sprinkler irrigation technology?

The first point is to spray the practicality of the irrigation equipment. It can improve the comprehensive utilization rate of water, improve the uniformity of irrigation, and realize the automatic management of equipment. Sprinkler irrigation technology is also known as artificial rainfall.

The use of this technology can achieve obvious effects such as water saving, production increase, and labor increase. It can also improve the microclimate in the field, such as humidification and cooling. Therefore, its practicality is relatively superior.

The sprinkler sprays into the air to form small water droplets, which drip evenly in the field to achieve the purpose of irrigation.

The second point is the type of sprinkler irrigation machine. Application of Sprinkler Irrigation Machine Sprinkler irrigation has many uses, mainly for crops, forestry nurseries, livestock meadows, vegetables and fruit trees, cash crops, garden lawns and flowers. In addition, it is also used for environmental control, sewage treatment, fish pond oxygenation, liquid fertilizer, herbicides, chemicals, pesticides, pesticides, comprehensive spraying, etc.

Sprinkler irrigation is highly adaptable and can be adapted to almost any crop, soil, terrain, region and climatic conditions. Commonly used sprinkler irrigation machines include small sprinkler irrigator, large sprinkler irrigator, translational sprinkler irrigator, circular sprinkler irrigator, double cantilever sprinkler and other types.

The third point is the strength of sprinkler irrigation. Irrigation intensity refers to the amount of water sprayed per unit area per unit time, or the depth of water sprayed on a green space per unit time. The average irrigation intensity when multiple nozzles with the same working pressure are combined in some form.

When the ground vegetation cover is good, the maximum allowable intensity can be increased. The selection of the system pipe diameter minimizes the annual cost of the pipeline, which includes investment cost and operating cost.

The fourth point is the determination of the sprinkler irrigation time. The working time of the sprinkler truck to meet the weekly water requirement of the plant must be calculated, and in order to achieve maximum soil water absorption, the interval between each watering must be more than 1 hour. Among them, soil permeability and plant perimeter water requirement can refer to the corresponding data comparison table.

Selection of water pumpWhen the water pressure and water volume of the water source cannot meet the requirements of sprinkler irrigation, the pump should be pressurized.

Sprinkler irrigation is a modern type of agricultural irrigation that has many advantages. First of all, sprinkler irrigation can save water resources because it can control the flow of water and the area sprayed, avoiding waste and abuse. This is especially important in water-scarce or water-scarce agricultural areas.

Second, sprinkler irrigation can improve agricultural production efficiency. It allows water and fertilizer to be sprayed more evenly on crops, promotes the growth of crop compounds, reduces land waste and improves soil quality. At the same time, it can control the intensity of water irrigation, reducing soil erosion and soil erosion.

Finally, sprinkler irrigation can reduce labor costs and improve labor efficiency in agricultural production. Irrigation systems can be automated and do not require a lot of manual work, which is important in areas where there is a shortage of labor and where farming is busy.

In general, sprinkler irrigation is an efficient, water-saving and labor-saving irrigation method, and it occupies an important position in modern agricultural production. With the continuous development of science and technology, the quality and efficiency of sprinkler irrigation systems are also improving, which will bring greater development space and opportunities for agricultural production.

A complete irrigation system is generally composed of a water source, a head hub, a pipe network and a sprinkler. 1.Water source:

Generally, the urban water supply system is mostly used as the sprinkler irrigation water source, in addition, wells, lakes, reservoirs, and rivers can also be used as water sources. Throughout the growing season of the lawn, the water source should be guaranteed to be reliably supplied. At the same time, the water quality of the source should meet the requirements of the irrigation water quality standards.

2.The first hub: its role is to take water from the source and pressurize it, treat it, inject fertilizer, and control the system.

Generally, it includes power equipment, water pumps, filters, fertilizer applicators, pressure relief valves, check valves, water meters, pressure gauges, and control equipment, such as automatic irrigation controllers, balanced pressure conversion control devices, etc. The number of first equipment can be increased or decreased depending on the type of system, water source conditions and user requirements. When the pressure of the urban water supply system can not meet the requirements of the sprinkler irrigation working pressure, a special water pumping station or a pressurized water pump room or a special water tower can be built, and sometimes tap water can be used.

Sprinkler irrigation plays a pivotal role in agricultural irrigation, has the role of saving water, saving labor, increasing yield, improving quality, etc., greatly promoting the development of agricultural economy, let me analyze the specific advantages of sprinkler irrigation.

1.Water conservation.

According to the experimental research, the irrigation water utilization rate of sprinkler irrigation can reach 72 93, which is generally 30 50 more water-saving than ground irrigation, and the water-saving effect is more obvious on the sandy soil with strong permeability and poor water retention capacity, which can reach more than 70. Sprinkler irrigation is less affected by terrain and soil, and the ground is moist after sprinkler irrigation, and the uniformity can reach 80 90.

2.Adaptable.

Sprinkler irrigation is suitable for a variety of terrain and soil conditions, not necessarily requires the ground to be flat, for the mountainous areas, hills, slopes and other areas with complex terrain and local high hills and potholes that are not suitable for surface irrigation, sprinkler irrigation can be applied; In addition, sprinkler irrigation can be applied to a wide range of crops, including all densely planted shallow root crops, such as leafy vegetables.

Sprinkler irrigation can be used for vegetables, root vegetables, potatoes, etc. At the same time, sprinkler irrigation technology is most suitable for highly permeable or subsident soils and sandy soils with thin tillage topsoil and strong permeability of subsoil.

3.Save labor and land.

The mechanization degree of sprinkler irrigation is high, and it is convenient to adopt small electronic control device to realize automation, can save a lot of labor, if the sprinkler irrigation fertilization technology is adopted, its effect of saving labor is more significant, in addition, the use of sprinkler irrigation can also reduce the labor such as repairing field channels, irrigation ditches and furrows. At the same time, sprinkler irrigation uses pipelines to transport water, and fixed pipelines can be buried underground, reducing the land occupation of field ditches, ditches, furrows, ridges, etc., and saving land 7 15 than surface irrigation.

4.Increase yield and improve quality.

Sprinkler irrigation can control the amount of irrigation in a timely and appropriate amount, adopt the method of less irrigation and frequent irrigation, so that the soil moisture is kept within the appropriate range of normal growth of crops, and at the same time, sprinkler irrigation irrigates crops like rain, which will not have a mechanical damage effect on the cultivated soil, maintain the soil aggregate structure, and effectively regulate the soil water, fertilizer, gas, heat and microbial status.

Sprinkler irrigation can regulate the field microclimate and increase the humidity of the air near the ground.

Adjust the temperature and the temperature difference between day and night, and avoid the harm of dry and hot wind, high temperature and frost to crops, which has an obvious yield increase effect, and the yield of general vegetables is increased by 1 2 times.

Sprinkler irrigation can flexibly adjust the irrigation time and irrigation amount according to the water demand of crops, the overall irrigation is uniform, and the fertilization plan can be adjusted in a timely manner according to the growth needs of crops, effectively improving the yield and product quality of agricultural products.

In short, good use of sprinkler irrigation is conducive to saving costs, improving income, and promoting the development of agricultural economy.

The advantage of sprinkler irrigation is that it is very water-saving, it can control the amount of water, and can make the irrigated area more uniform, which can generally save about 30 50% of water. At the same time, it can also play a very good role in increasing yield and creating a good growth environment for crops. In addition, the adaptability is very strong, especially the land saving, and the efficiency is also very high.

The advantage should be that it can ensure that every crop will basically have water, and it will ensure that every crop will grow normally and will not die due to lack of water. With this kind of sprinkler irrigation, it may make the whole watering process particularly convenient and allow us to save water.

The advantage of sprinkler irrigation is that it can save water, can save water, irrigate a large area, do not waste any drop of water, can save time, can save physical, can save costs.

1. Water saving. Sprinkler irrigation can control the amount and uniformity of irrigation, without deep seepage and surface loss, and can adjust the amount of sprinkling according to the water demand of crops, thus greatly saving irrigation water consumption. Generally, it can save 30-50 water, and more than 70 can be saved on sandy land with strong permeability and poor water retention capacity.

2. Increase production. Irrigation can be controlled in a timely and appropriate amount to keep soil moisture within the appropriate range for normal crop growth; It does not have a mechanical damage effect on the soil cultivated layer and maintains the soil aggregate structure; Regulate the microclimate, and play a cooling role in the hot season; Effectively regulate the water, air, heat, nutrient and microbial status of the soil; Rinse off the dust on the stems and leaves, which is conducive to crop respiration and photosynthesis; In the cold season, it can prevent frost, increase foliar temperature and ground temperature, create a good growth environment for crops, and achieve obvious yield increase effect.

1) Initiation phase. After the jet passes through the deflector plate jet deflector plate, it turns to 60 ° 120 °, and the deflector obtains the anti-spitting force of the jet, so that the rocker arm obtains kinetic energy and swings outward, and rotates around the rocker arm axis to make the rocker arm spring twist and obtain a torsional moment, which is less than the jet reaction moment, so the rocker arm obtains angular velocity and leaves the jet.

2) Swing out stage. The inertial force makes the rocker arm continue to rotate until the swinger angle reaches the maximum, so as to obtain the maximum torsional moment, at this time the angular velocity changes to 0, and the spring potential energy reaches the maximum, that is, the kinetic energy of the rocker arm swings out is all converted into the elastic potential energy of the spring.

3) Bounce back phase. Under the action of the torsional moment of the spring, the elastic potential energy of the spring is gradually converted into the rotational kinetic energy of the rocker arm, and the rocker arm begins to swing back, and the angular velocity continues to increase until the rocker arm is about to cut into the jet.

4) In the water entry stage, the rocker arm with the maximum rotational kinetic energy re-enters the jet, and the deflector plate begins to accept the water flow first (the water deflector plate is not subject to water), and the reaction force generated makes the rocker kinetic energy increase sharply, and the angular velocity becomes larger and larger.

5) Impact phase. Under the action of the rotational inertia force and the tangential additional force of the deflection guide, the rocker arm begins to collide with the nozzle at a great angular velocity, so that the nozzle rotates 3 ° 5 °, and after the collision, the rocker arm completes a complete rotary motion process. Under the action of the frictional moment, the sprinkler head quickly came to a standstill and stopped.

After that, the rotational motion process is repeated.

The pressure of the water jet is used to strike the spring, and the power of the spring is used to rotate.
