Lawn requirements of the World Cup are very difficult, for example, the height of grass should be 28 mm, the error should be 2 mm, the turf should maintain moderate humidity, and the rolling tension should reach about 60 kg to 65 kg. Only the lawn certified by FIFA can appear on the stage of the World Cup.
This is very difficult for Qatar in the desert area.
When it comes to lawn irrigation, we have to mention China. The overall irrigation project that Qatar cooperated with us this time is worth more than one billion RMB.
It takes 1 10,000 liters of fresh water to water a stadium every day. In addition, Qatar has reserved 8 competition venues and 136 training venues for this World Cup. With so much water demand, the pressure on Qatar is even greater. Because its region is half desert and half ocean, fresh water resources can be said to be very scarce, with high temperature and little rain all year round, and the average annual precipitation is only 125mm. It is no exaggeration to say that water is more expensive than oil in Qatar. Where does the water come from? In addition to Boss Ka spending huge sums of money to build many desalination plants, China Nengjian Gezhouba Group also came to help. Water storage dams were built in the desert, with 0/5 reservoirs/kloc-,each with a storage capacity of 500,000 cubic meters. It is the largest single reservoir in the world at present, which can meet the water demand of millions of people. But with water, shopping can't be wasted. You should keep it, right? So this time, Ningxia University gave a very good solution to the lawn irrigation of the stadium, that is, underground infiltration irrigation technology. Simply put, water and fertilizer are directly applied to the roots of grass, giving up the traditional ground sprinkler irrigation. The advantage of this is that the evaporation loss caused by spraying can be reduced in hot and dry areas, and the energy supply of the whole system is completed by wind energy and solar energy, which also achieves the technical purpose of reducing carbon. At the same time, it can realize intelligent automatic control of sprinkler irrigation area and sprinkler irrigation time, realize accurate irrigation and efficient water saving, and greatly save labor costs. This technology saves about 40% fresh water compared with traditional lawn planting. In addition, the irrigation equipment is laid underground and is not exposed to ultraviolet rays, so the service life is relatively longer.
More than 90% of the technologies exported to Qatar have independent intellectual property rights. We applied for two international patents in the United States and the United Arab Emirates, and obtained more than 30 invention patents in China.
It is precisely because we have confidence and strength that we will show this black technology on the stage of the World Cup. After all, those who can go abroad are all projects that can be taken.
