With the gradual advancement of agricultural modernization, more and more farmers are using greenhouses to grow vegetables. In addition, compared with other irrigation methods, drip irrigation not only has the advantages of water saving, energy saving, and dehumidification, but also can adjust the microclimate, improve the crop growth environment, and connect irrigation for topdressing and pesticide application. Therefore, the irrigation of vegetable greenhouses mainly relies on drip irrigation technology. In order to smoothly implement the entire drip irrigation process, it is necessary to select appropriate drip irrigation belt equipment and then work together. However, in the actual drip irrigation system, many times the entire drip irrigation system will collapse due to problems with the drip irrigation belt equipment, not to mention accelerating the growth of vegetables in the greenhouse, which is impossible to do. So, how can drip irrigation in vegetable greenhouses be ensured to be implemented smoothly? What are the maintenance and repair measures for drip irrigation belt equipment? The following is an introduction to this aspect brought to you by Shandong Hengxiang Plastic Machinery Co., Ltd. so that you can understand it.

In order to ensure the realization of the drip irrigation system, drip irrigation belt equipment is required, and the drip irrigation belt equipment includes: drippers on the pipe, drip irrigation belts, and drip irrigation pipes; at the same time, in order to prevent the drippers and drip irrigation pipes (belts) from being blocked, filters need to be installed. Common filters include mesh filters, centrifugal filters, sand and gravel filters, etc. So, what are the maintenance and repair measures for drip irrigation belt equipment?

(1) Uneven dripping. It means that the dripping of the micro-tubes at both ends of the greenhouse loses balance, usually manifested as excessive dripping near the water source and insufficient water at the far water source. This is mainly caused by insufficient water pressure or unreasonable branch pipe installation, resulting in reverse slope. In this case, the water supply pressure should be increased and the slope of the branch pipe should be adjusted.

(2) Dripper blockage. The main reason is poor water quality and high sand content, which causes sand to block the micro-tube holes; in this case, what we can do is to check the filter first, then dredge or replace the blocked micro-tube, or flush it with clear acid or add water pressure to dredge it.

(3) Jet and slow drip. In the same microtube surface, the dripper near the branch pipe has jet flow or drips too fast, while the dripper at the branch pipe drips slowly. The main reason is that the spacing and length of the microtubes are unreasonable. The solution is: adjust the spacing of the microtubes, increase the spacing of the microtubes at the head end of the capillary tube, and reduce the spacing of the microtubes at the tail end; or adjust the length of the microtubes, lengthen the microtubes near the branch pipe, and shorten the microtubes at the far branch pipe; if individual microtubes drip too fast, you can temporarily buckle them to increase resistance and control the water volume; if you find a microtube with poor water flow, use your fingers to twist it to make it soft and unobstructed.

(4) At the same time, in order to ensure the smooth flow of water, the filter should be cleaned regularly.
