Drip irrigation tube is a product with a long service life. Mastering the maintenance methods can extend the service life and reduce the cost. Drip Irrigation Accessories supplier will show you how to maintain drip irrigation tape.
Poor water quality and low maintenance frequency can cause blockages caused by low-soluble salts (such as calcium carbonate), bacteria, and algae;
Breakage of drip irrigation pipe caused by the bite of snakes, rats, insects and ants;
The drip irrigation pipe is damaged by external physical damage such as sharp objects and heavy objects falling in the soil;
Improper daily management and maintenance methods such as laying, recycling, and storage.

It is not advisable to fold back and forth frequently during use, and a disc should be prepared for recycling before recycling;
During the period of crop cultivation management, the drip irrigation pipe should be placed aside before cultivating operations, so as not to damage the drip irrigation pipe due to improper operation;
After the fertilizer is applied, clean water should be dripped for a period of time to clean the pipes and drippers to avoid clogging of residues;
During the irrigation season, the drip irrigation pipe should be flushed every 2-3 weeks. Rinse for 30-60 seconds by opening the automatic flushing end until clear water is confirmed. Automatic flushing valve can be used to flush to reduce labor costs and ensure continuous flushing;
It is recommended to use acid treatment as a part of routine maintenance procedures. Acid injection is recommended to reduce blockage caused by low-soluble salts (such as calcium carbonate). 33% hydrochloric acid or 85% phosphoric acid is recommended.
Determine the amount of acid to be injected: take a 10l capacity bucket and inject a small amount of acid several times to test whether it reaches the required pH value. Once the required pH value of 2.0 is reached, by multiplying the amount of acid by 100, the demand for acid injection at 1m³ of displacement can be obtained.
Note: When preparing the acid solution, be sure to add acid to the water, do not add water to the acid; for specific adjustment of the pH treatment, refer to the advice of the agronomist to prevent the impact on the crop.
Treatment instructions: In the irrigation season or when the system discharge drops by 5%, acid treatment should be performed 1-2 times. Rinse all branches and sides before acid treatment. Check the system displacement before processing so that it can be compared with the displacement of the processed system later.
Solution preparation: The volume of the solution (water + acid) should be equal to 1/4 of the hourly displacement of the syringe. This water injection will last 15 minutes. We recommend working with the maximum displacement of the syringe to avoid the use of highly concentrated solutions.
Only start injection after the system is filled with water and the dripper shoots water.
Control: Use a litmus test strip to check the pH value of the residual acid at the outermost part (pH 2.0). A second injection is recommended when no residual acid is detected. Inject within 15 minutes. Irrigate continuously for 30-60 minutes to ensure complete system flushing. Check the system displacement.
Chlorine is a bactericide that destroys microorganisms: bacteria, algae, etc. Chlorine injection can reduce blockages and help keep irrigation lines clean. It is recommended to adopt intermittent treatment or on-site preventive treatment, and use water with high concentration of organic materials during treatment. The most commonly used material is 10-12% sodium hypochlorite. When the water pH is higher than 7.5, the chlorination effect will be reduced, and acidification to pH 6.5 will maximize the effectiveness of the chlorine treatment.
Contact time: The minimum contact time for effective chlorine treatment is 30 minutes to kill microorganisms. This time starts from when free chlorine is detected in the dripper outlet.
Warning: Active chlorine is very dangerous, please follow the instructions.
Storage: Sodium hypochlorite should be stored in a clean and cool place without any fertilizer residue. Its concentration will decrease over time.
