How to maintain water-saving irrigation equipment in a greenhouse during the hot summer?

With the promotion of irrigation products such as water and fertilizer integrated machines, the frequency of their use in vegetable greenhouses has also increased. So, how should water-saving irrigation equipment be maintained in the hot summer days in greenhouses?

  Summer is the stage for soil treatment during the fallow period of changing crops, requiring the fertilization machine and other irrigation equipment to be put away for temporary storage. A reminder again to all vegetable farmers, the following four points should be noted.

  First: Flush the pipes clean of mud and sand before putting them away.

  Most of the filters for water-saving irrigation and fertilization installed in greenhouses are mesh filters and disc filters. These two types of filters have a good filtration effect on larger sand particles, while finer sand will pass through the filter mesh or disc and Enter the pipe, accumulating inside.

Therefore, before putting away the capillary tubes of the water-saving irrigation system, open the closed ends of the capillary tubes and flush out the mud and sand by adding water pressure. During the flushing process, you can lift the capillary tubes and shake them several times before removing them. After draining the water from the capillary tubes, they can be put away.

   Second: After putting them away, store them in a dark, cool place.

   After putting away the pipes, store them in a dark, well-ventilated, cool place. Do not expose them to strong sunlight, as this will severely reduce the service life of the pipes. When communicating with vegetable farmers, the company's engineering and installation personnel have found that many farmers place the pipes on the vine steel wires under the ventilation openings, and leave them there until the next batch of vegetables are planted, as long as it does not get in the way. Some farmers leave the pipes in the greenhouse and then carry out soil fumigation, which will greatly reduce the service life of the pipes.

   The best way is to roll up the pipes and avoid folding them, as the pipe wall at the folded corners is easily worn, and if there is a leak, the entire pipe will be unusable.

   Third: The main pipe of the front curtain can be covered with non-woven fabric.

   The main pipe of the water-saving irrigation equipment installed in the greenhouse is generally located at the front of the greenhouse, where there is less farming work, and basically no further adjustment is needed after the pressure is adjusted during transactions. However, in summer, the main pipe needs corresponding protection. Although the main pipe is relatively hard, it should not be exposed to high temperatures and strong sunlight. It is recommended to cover the pipe with non-woven fabric to avoid direct sunlight.

   Users with intelligent fertilization machines in the greenhouse need to remove them before soil fumigation and store them in a cool and dry place to avoid aging of the components due to high temperature and strong sunlight.

   Fourth: Damaged pipes should be removed promptly.

   After several years of use, water-saving irrigation pipes will gradually show some damage. When putting away and storing the pipes each time, carefully observe whether there is any damage or blockage. If so, promptly remove and replace them.
