    On October 10th, a joint research and development team of the Institute of Process Engineering of the Chinese Academy of Sciences (hereinafter referred to as the Institute of Process Engineering), Northern University for Nationalities and Ningxia Agricultural Reclamation Helan Mountain Farm (Co.


    In order to solve the problems of coal-burning waste "fly ash" and environmental pollution, researchers from the Institute of Process Engineering and Northern University for Nationalities proposed that fly ash can be used in large areas of salinized land after harmless and targeted selective activation.


    It is understood that the area of ​​salinization in Ningxia is 2.


    In view of the large amount of fly ash produced in Ningxia, the traditional way is difficult to absorb, and the large area of ​​saline-alkali land urgently needs to be improved, a new type of fly ash-based soil conditioner is prepared using fly ash modification and multi-nutrient synergistic integration technology , Carry out research on saline-alkali soil improvement system, repair saline-alkali soil, and simultaneously realize bulk consumption of fly ash


    Ma Shuhua, a researcher at the Institute of Process Engineering, Chinese Academy of Sciences, introduced that the R&D team succeeded in making breakthroughs in multiple core technologies such as low-cost deep removal of heavy metals in fly ash, directional activation of fly ash, structural reconstruction of saline soil and nutrient balance, etc.


    Through the improvement of the five-month planting season, the pH value of the land has dropped to 8.


    It is understood that the total area of ​​the experimental field tested this time is 400 acres, and the planting area is 340 acres


    Ma Shuhua said that the research results of this project can be widely promoted across the country, which can improve the saline soil, increase crop yields, and absorb a large amount of solid waste of fly ash, which will contribute to the sustained and healthy development of the industrial and agricultural economy in the coal industry base in western China.


    The relevant person in charge of the Ningxia Science and Technology Department stated that the development and application of new materials for improvement of fly ash-based saline-alkali land has a significant effect on crop production.
