1. When laying the drip irrigation tape, keep the labyrinth side up (that is, the embossed protrusion side up) and lay it flat on the film. Next, don't shop, don't twist.
2. When laying the drip irrigation belt, if it is laid by machinery, bearings must be placed on the pulley and the rotating mechanism to ensure that the pulley rotates flexibly, and the drip irrigation belt cannot be pulled, which will cause labyrinth deformation and affect the drip water.
3. After the system is installed, water should be delivered to the drip irrigation system in time to prevent the explosion of solar ultraviolet rays and accelerate the aging of pipelines and drip irrigation belts.
4. When installing, the staff should read the instructions of each component carefully and connect each component with the correct installation method.
5. Once the main pipe, branch pipe and auxiliary pipe are installed in the plot, agricultural machinery and tools should be strictly rolled and scraped to avoid external damage and reduce service life.
6. After the installation of drip irrigation equipment is completed, special personnel shall be arranged for management. It is forbidden for others to disassemble and open and close the valve without permission.
7. The plot where drip irrigation equipment is installed should be carefully prepared and the stubble should be cleared. Stubble, stones, weeds and other things are easy to pierce the drip irrigation belt and hold up the plastic film, which leads to the accumulation of water vapor in the plastic film and forms a lens effect.
8. When laying, the drip irrigation belt can be buried shallowly to avoid focal burns. You can also spread a layer of soil with a thickness of about 1 mm on the drip irrigation tape or plastic film to destroy the formation of lenses and avoid scalding.
Irrigation should be carried out in strict accordance with the rotation irrigation group, otherwise it may cause uneven water output or poor pump work, resulting in energy waste and failure to achieve the purposes of saving water, electricity, fertilizer and labor.
10. After the drip irrigation, the trunk, the main pipe and the joint should be recycled for use next year.
1 1. After the dirt in the filter accumulates, the loss of overcurrent increases. When the pressure difference between the two ends of the filter is 0.2-0.3MPa, it must be cleaned.
12. Open the end of the drip irrigation pipe regularly to wash the dirt in the dropper.
What should I pay attention to when buying drip tape? First of all, we should know the manufacturers and operators.
Need to know whether the purchased drip irrigation tape is produced by a regular manufacturer, whether the operator has a regular business place and business qualification, and what is the quality of the drip irrigation tape operated by its operator in the past? Do not know the manufacturer's drip irrigation tape, unfamiliar mobile operators and salesmen can not buy it.
Second, we should consult the quality and technical supervision department and the water conservancy department.
Before you want to buy the drip irrigation tape, you should consult the technical supervision and management department above, so as to be more familiar with the performance and application technology of the drip irrigation tape and avoid being cheated.
Thirdly, the product was tested on the spot.
When purchasing, touch it by hand first to understand the quality problems such as the thickness and firmness of the drip irrigation belt; Then cut out more than ten meters long sections from different packages, and directly connect them to the faucet of drip irrigation to add water and try to drip. When observing, if the drip hole on the drip irrigation belt drips very evenly and there is no water leakage in other places, it means that the drip irrigation belt is fine; If the drip tape drips unevenly, some are small, some are big, some are fast, some are slow, some are not dripping, and some even leak water. , is not a qualified product and cannot be purchased.
Fourth, don't blindly covet cheap.
As the saying goes, "cheap goods are not good, and good goods are not cheap." Cheap things often hide defects of poor quality or inferior quality, so you must be careful when buying them.
Fifth, we must sign a formal contract.
Before buying the drip irrigation tape, a formal contract should be signed to ensure the product quality. There must be three guarantees of quality (return, replacement and repair) in the contract, and what kind of responsibilities should be taken after breach of contract to ensure the normal performance of the agreement.
In order to ensure that your field crops grow well, save water and increase income, and achieve remarkable benefits, please carefully choose drip irrigation belts.
What should I pay attention to when using patch drip irrigation tape? Matters needing attention in using patch drip irrigation tape:
First, the drip irrigation pipe and the emitter are easy to block, which requires high water quality, so filters must be installed;
Second, drip irrigation can not adjust the microclimate in the field and is not suitable for irrigation during the freezing period. In vegetable irrigation, drip irrigation system can not be used for topdressing.
Third, the investment in drip irrigation is high, and the economic benefits of crops should be considered;
4. Burn of drip irrigation belt Pay attention to the compaction of mulch film when laying drip irrigation belt, so that mulch film can be as close as possible to drip irrigation belt, and there is no gap between mulch film and drip irrigation belt. Avoid the focus of sunlight through water droplets. Before sowing, the land should be leveled to reduce the phenomenon of many pits and depressions in the land. Prevent clods, stones and weeds from lifting up the plastic film, causing water vapor to accumulate under the plastic film to form a lens effect and burn the drip irrigation belt. When laying, the drip irrigation belt can be buried underground to avoid focal burns.
The width of plastic film is 1.4m, and the amount of drip irrigation tape per mu is calculated according to the laying of double-layer drip irrigation tape. At first glance, you are also a farmer. How can you calculate the sowing width without you? If it is film theory, it needs 953M, which is mainly related to the mechanical broadcast you use.
How much it costs to lay drip irrigation pipe drip irrigation belt on farmland depends on your land and drip irrigation pipe. According to the specifications of the drip irrigation belt, the drip irrigation belt of 16 mm is about 0.2 yuan meters.
What should I pay attention to when installing drip tape? The installation steps and precautions of drip irrigation belt account for the largest proportion in the whole water-saving irrigation system, and it is time-consuming and laborious to install drip irrigation belt, but correct and good installation can make drip irrigation belt have more stable and even flow and longer life. The following drip irrigation tape manufacturer Xiamen Huadai Irrigation will explain the detailed steps and precautions in the installation process of drip irrigation tape for you. 1. First, according to the construction drawing of drip irrigation belt installation scheme, check whether all equipment models, specifications and sizes correspond. Keep the equipment to be installed clean inside and outside. Drip irrigation belt belongs to fragile equipment and cannot be transported and installed by violence.
2. After the distance between drip irrigation belt and branch pipe is reserved, drill holes on pe branch pipe according to plant spacing or other regulations. Special drilling tools must be used to drill holes, and the drilling depth should not exceed half of the hole diameter, otherwise the drip irrigation belt may be damaged. Flower-mouth irrigation emphasizes that if it is an embedded drip irrigation belt, pay attention to the labyrinth channel convex surface facing upwards.
3. Install and lay drip irrigation belt according to plant row spacing. When cutting the drip irrigation belt, it should be longer than the length of the plant row in order to keep it. Xiamen Huadai Irrigation said that this is to prevent the joint from consuming the length of the drip irrigation belt due to perforation damage, or to adjust the accurate position of the outlet hole. When cutting, it should be perpendicular to the cross section of the drip irrigation belt.
4. Install drip irrigation belt and branch pipe through special bypass connection, and pay attention to control the relative position of water outlet and plants when connecting.
5. Turn on the water source and slowly open the valve to flush the drip irrigation belt. Don't suddenly open it completely. The most common irrigation explanation in China is to prevent the instantaneous high water pressure from damaging the drip irrigation belt. Rinse residual particles and impurities after water supply, install a special drip tape zipper plug at the other end of the drip tape for plugging, and also install a plug at the end of the branch pipe for plugging.
How to calculate the laying distance of drip irrigation belt? Determine the laying distance of drip irrigation belt according to the distance between plants.
What should I pay attention to when using drip tape? Precautions for installation of drip irrigation belt:
1. Flat emitter drip irrigation belt is an integrated drip irrigation belt with flat emitters embedded in the inner wall of the pipe belt, which is widely used in greenhouse and field cash crop irrigation.
2, the emitter and the pipe belt are integrated, which is convenient to use, low in cost and less in investment.
3. The transmitter has a self-filtering window, which has good anti-blocking performance.
4. The labyrinth flow passage is selected, which has certain pressure compensation function.
5. The distance of the transmitter can be determined according to the needs of users.
Notes on Drip Irrigation Belt: Drip Irrigation Belt uses plastic pipes to send water to the roots of crops for local irrigation through orifices or drippers on capillaries with a diameter of about 10mm, and drip water into the soil near the roots of crops evenly and slowly through drippers or drip irrigation belts with small outflow orifices.
Drip irrigation belt installation is divided into the following procedures:
1. Punch the branch pipe. First, punch holes in PE pipes, PVC pipes and branch pipes of water conveyance belt with special punching objects.
2. The water delivery pipeline is connected with the drip irrigation belt, and the water delivery branch pipe is connected with the drip irrigation belt through a special bypass.
3, cleaning and head
Several use forms of drip irrigation belt/notes on drip irrigation belt 1. Classification of drip irrigation belt
1, patch drip tape
2, maze drip irrigation belt
3. drip irrigation pipe
Drip irrigation is a precise irrigation method, which uses a low-pressure pipeline system to transport water directly to the field, and then drips it into the soil near the root zone of crops evenly and slowly through the dripper, orifice or drip irrigation belt installed on the capillary, so that the soil in the most developed root zone of crops always keeps proper humidity, and the activities of water, fertilizer, gas, heat and microorganisms in the soil are always in a good state, which creates advantages for high and stable yield of crops. Drip irrigation belt is divided into patch drip irrigation belt and labyrinth drip irrigation belt.
Second, the use of drip irrigation belt precautions
1, drip irrigation pipes and emitters are easy to be blocked, which requires high water quality, so filters must be installed.
2. Drip irrigation can not adjust the microclimate in the field, and it is not suitable for irrigation in freezing period, nor can it be used for topdressing in vegetable irrigation.
3. The investment of drip irrigation is high, and the economic benefits of crops should be considered.
Third, the role of drip irrigation belt
It is the most effective water-saving irrigation method in arid and water-deficient areas at present, and the water utilization rate can reach 95%. Drip irrigation is more effective than sprinkler irrigation in saving water and increasing yield, and can be combined with fertilization to improve fertilizer efficiency by more than one time. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-deficient areas. Its disadvantage is that the emitter is easy to scale and block, so the water source should be strictly filtered. At present, domestic equipment has basically reached the standard, and areas with conditions should actively develop drip irrigation.
What should I pay attention to when installing drip irrigation belt in the field? Suitable for cotton, Chinese herbal medicines, watermelons, field vegetables and other field crops, improving the intensity of mechanized planting. The drip irrigation belt can be bent and laid around the ridge, which is convenient to operate. The characteristics of drip irrigation belt are: 1, labyrinth channel and drip hole are integrally formed by vacuum hot pressing at one time, with good adhesion and high manufacturing accuracy. 2. Turbulence produces more water and has strong anti-clogging ability. 3. Labyrinth runner design, uniform water outlet, up to more than 85%, laying up to 80 m.. 4. Light weight, convenient installation and management, and low manual installation cost. However, labyrinth drip irrigation belt has inherent disadvantages. Compared with patch-type drip irrigation belt, it has the following characteristics: 1, and the built-in dripper has its own filter window, which has good anti-blocking performance. 2. Turbulent channel design. Uniform irrigation. 3. The transmitter and pipeline have strong integrity; 4. The distance between transmitters can be flexibly adjusted, with wide application range and low price.
