According to the beijing morning post, the qingjiang rice research and development centre team led by yuan longping, a member of the chinese engineering institute, recently measured rice planted in the dubai tropical desert, with a maximum acre production of over 500 kg. This was the first global success in piloting rice cultivation in the tropical desert, adding “china's contribution” to improving food self-sufficiency, global food security and the ecological environment in the desert. Many wonder how hard it is to grow rice in the dubai tropical desert. How did the desert grow rice
In an interview with the people's daily newspaper, zhang kuodong, deputy director of the qingdao rice research and development centre, stated that the greatest challenge to local rice cultivation in dubai was the low organic content of desert soils, which could not be protected, and the sea water, which was more than 7. 5 metres underground. The local freshwater is valuable and relies mainly on desalination, so ordinary irrigation methods are not feasible. The xinhua network adds that freshwater seepage collides with underground seawater, which, under high-light conditions, is prone to subsurface seawater rise and secondary salinization. In addition, the daily and night temperatures in the dubai desert range by more than 30 degrees celsius, extreme weather during the day, surface temperatures by more than 50 degrees celsius, humidity by less than 20 per cent and frequent sand and dust storms。
So, how does rice grow in such a bad environment? According to people's daily, the qingdao rice research and development centre team has used its original “4d improvement” land improvement technology to provide technical security. Among them, the ecm is the most critical core technology。
According to the daily mass, the four-dimensional improvement approach, with saline-resistant rice at its core, integrates the four main elements of the network of goods, soil orientation regulators, plant growth adjusters and anti-reversible rice technology in a free mix, tailored to the needs of the species, nutritional mixes, salt management systems, to make the best solutions for the target soil and “live” the soil and crops. In addition to improving coastal and inland salinization, the 4d improvement method allows for the rehabilitation of heavy metal contamination and agricultural waste。
For the core technology of factor network modules, xinhua reported that it consisted mainly of two pipelines with multiple sensors, the first of which automatically delivered the required manure to the root of the rice system, based on the feedback demand of the sensor, and the second of which recovered excess water manure from the soil and transported it to the recovery pool for recycling. Element network modules also have smart spraying irrigation systems on the surface that allow accurate control of jets and shotguns for regular time-spraying of water and nutrients based on the characteristics of the need for fattening over time, soil environment and nutrient content.
