If someone tells you Just sprinkle a layer of "white soil" and add some water It can turn the yellow sand in the desert into soil It is also a "fertile soil" suitable for vegetation growth. Would you believe it? Last year Because of the scientific breakthrough of "turning sand into soil" 58-year-old mechanic Yi Zhijian Won the title of "Most Beautiful Science and Technology Worker in 2021" If it runs according to the normal trajectory Yi Zhijian's life has nothing to do with "sand" He was born and raised in Chongqing. Since I was admitted to university Now he teaches at Chongqing Jiaotong University He has been studying mechanics all the way I was not born on the edge of the desert Second, I don’t study ecology, plants, soil, geology The professional backgrounds of these "counterparts" in sand control Yi Zhijian led a research team in 2016 In the vast sea of sand in the Ulan Buh Desert in Inner Mongolia "Transformed" into an oasis as big as two football fields This is almost a miracle. In 2009, Yi Zhijian's team An original mechanical principle proposed At that time, they found that there was a "Universal Joint Constraint Relationship" Under this constraint Soil particles have a certain flexibility Can retain water, fertilizer and breathable It also has a certain rigidity Can maintain plant stability The desert is so barren. Because the sand particles don't exist. "Universal Joint Constraint Relationship" If there are no constraints, try to establish them. Holding the scientific theory "code" of "turning sand into soil" Yi Zhijian devoted himself to the "desert soilification" experiment In 2013, the research team developed a Plant cellulose adhesive This is the "white soil" mentioned at the beginning. Mix it with sand and add appropriate amount of water "A plate of loose sand" can be obtained Same eco-mechanical properties as natural soil April 2016, Alxa League, Inner Mongolia Ulan Buh Desert Becomes Yi Zhijian's Team The first "experimental field" targeted "Ulanbuhe" means "red bull" in Mongolian Desertification has become apparent since the Tang and Song dynasties "The sand is three feet deep and the horses cannot move forward" In modern times, it has become a mobile desert with no grass growing on it. The Red Bull has been rebellious for thousands of years However, after several months of hard work by Yi Zhijian and his team The first time he showed his docile side—— White clay plays a role By August of that year, a A vibrant "island" with fragrant fruits and vegetables Desert soil field test succeeds in first battle Yi Zhijian led the team to fight again More test sites with harsh natural conditions Taklimakan Desert, Hotan, Xinjiang Desertified grassland in Ruoergai, Sichuan Desertification zone in the suburbs of Lhasa, Tibet Xisha Islands … In the desert with a total area of 17,000 acres Their ecological restoration and agricultural planting experiments All successful The desert is a no man's land "Mechanical sand control" is also a "no man's land" that no one has ever reached before Although the trial was successful However, the theories and technologies created by Yi Zhijian's team are Still facing various controversies The authenticity and value of this technology are questioned A few experts even doubt that it may bring "harm" “When an original scientific achievement is born It is normal to be noticed and even questioned by people.” Yi Zhijian's team insists on speaking only facts Field trials for 6 years They collected a lot of data to answer questions The problem with deserts is drought. Don't we need "white soil"? Can plants grow as long as they are watered enough? Experimental data from Inner Mongolia and Xinjiang show that Water consumption of crops in the "desert soilification" experimental site Lower than the local farmland water-saving irrigation quota Are the materials added to “white clay” polluting? Multiple tests by authoritative organizations have shown that The added materials do not contain any toxic or harmful substances Soil, water and atmosphere All meet the national green food origin certification standards Desert is one of the components of the earth's natural ecology Turn the desert into an oasis Is this an act of destroying the ecology? Regarding the last question Yi Zhijian’s view is: Desertification is called the cancer of the earth It is a major ecological and environmental problem facing mankind. my country has always attached great importance to desertification prevention and control. The purpose of the research and development of the "desert soilification" technology is to It is not to transform all deserts. How to apply the technology after it matures There must be a scientific and reasonable overall planning Yi Zhijian's team insists on speaking with facts In recent years, the number of doubts has gradually decreased. More and more affirmation and support “Seeing high-yield crops grown in the desert I was shocked and moved.” Han Guiqing, the first chairman of the FAO Black Soil Alliance When evaluating the technical achievements of "desert soilification", he said emotionally “No matter what other experts say, as an agronomist I strongly support this disruptive innovation." Mr. Yuan Longping had a dream of "enjoying the coolness under the rice plants" Yi Zhijian, a desert control expert who changed his career There is also a dream of "turning sand into fields" He wants to use his technology Transform 1% of my country's desertified land In exchange for 26 million mu of usable land Mechanics meets the desert It’s the honor of my life.” Waiting for his dream to come true Mechanics meets the desert Or the honor of an era." Salute to scientists! May the dream of “turning sand into fields” come true soon!
