The control of the corrosion of groundwater by well pipes mainly starts from two aspects. The first is to improve the corrosion resistance of pipes and use materials with good corrosion resistance. The second is to remove or inhibit some of the factors that cause corrosion. There are generally the following anti-corrosion measures: 1. The use of high-quality materials with good corrosion resistance, connecting screws, and copper wire ropes can extend the service life by several times. The same type of metal material should have a smooth surface and should not be rough; it should be annealed and not hardened. Welds at stress concentration sites are prone to corrosion and should be avoided during production and installation. 2. Coating (plating) protective layer The coating (plating) protective layer on the surface of the pipe has the following characteristics: electrical insulation, integrity and durability. The coated material has a certain degree of adsorption force and strength, and is non-toxic and economical. 3. Replace the well pipe connection screw of the deep well submersible pump. Every year we must put forward the wellhead maintenance and replacement. It is better to connect with the galvanized screw. Wire ropes are oiled or covered with plastic tubes. 4. Strengthen regulation In areas where heavy calcium carbonate precipitates heavily, try to take various measures to reduce the water jump in the water supply pipe well and reduce the water inlet speed, that is, increase the size of the filter, increase the water intake area, and use small pumping when the water demand is determined. Drop, upper limit of filler diameter. Ventilation is one of the most important components in a successful greenhouse.

If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
