Zhengsai's Saline-alkali land treatment technology

On January 21, 2024, a top expert team composed of academicians of the Chinese Academy of Sciences and authoritative experts from the Ministry of Science and Technology, the Ministry of Environmental Protection, and others conducted a scientific research evaluation on Zhengsai's technology for improving saline alkali land and restoring green land through tailings pond closure without guest soil. This technology was rated as an internationally advanced level.

In 2023, the General Office of the Communist Party of China Central Committee issued Document No. 44 (2023) on promoting the comprehensive utilization of saline alkali land, emphasizing the important significance of comprehensive management of saline alkali land for national development strategy. The results of this evaluation once again prove the irreplaceability of Zhengsai in the field of ecological and environmental protection!

Experts participating in the evaluation of scientific and technological achievements: Han Buxing, academician of CAS Member, researcher of Institute of Chemistry, Chinese Academy of Sciences Peng Yingdeng, Chief Engineer and Researcher of the National Urban Environmental Pollution Control Engineering Technology Research Center Yang Xiaosong, Professor level Senior Engineer at the Environmental Engineering Research Institute of Beijing Institute of Mining and Metallurgy Li Anding, Senior Engineer of the Environmental Development Center of the Ministry of Ecology and Environment Zhang Huijin, Senior Laboratory, Institute of Botany, Chinese Academy of Sciences Sun Jiayue, Professor of the New Materials Committee of the Chinese Chemical Society Zhou Ying, Researcher at the Torch Center of the Ministry of Science and TechnologyUnit of completion: Wang Fuzhou, Zhengsai Group chairman, senior engineer Zhang Weiran, Zhengsai Group technical assistant Shuli Xing, Technical Assistant of Zhengsai GroupSpecial Guest: Qie Zhihong, Dean of College of Urban and Rural Construction, Agricultural University of Hebei

Before the evaluation meeting, the domestic and foreign experts who visited the salt-alkali land demonstration base and the academician team who participated in the evaluation all praised Zhengsai's technology and gave it a high degree of recognition. This is the affirmation of Zhengsai's unremitting exploration and efforts over the years, but also a clear proof of its technical strength.

Zhengsai's saline-alkali land improvement technology, with innovative, unique, scientific and accurate means, successfully solved the long-term problems of saline-alkali land that plagued local agriculture and ecological construction. Through the introduction of advanced land improvement technology, saline-alkali land has not only been comprehensively managed, but also full of vitality. When the barren land gradually turned into a fertile pastoral scene, when the abandoned farmland came back to life, Zhengsai's technical results were amazing.

And the green restoration technology of tailings pond without guest soil closed reservoir is another masterpiece of Zhengsai! This technology not only effectively solves the safety problem of tailings pond, but also realizes the maximum utilization of resources. Through scientific and reasonable technical means, the tailings pond has been effectively closed and the renewable resources have been fully utilized, which is also a unique initiative in the world.

The successful practice of saline-alkali land improvement and tailings pond restoration has not only won a good environment for us, but also set an example for global ecological construction. Zhengsai's unique technological advancement and persistent research over the years have set a model for technological innovation, which cannot be ignored.

On the road of future development, Zhengsai will continue to uphold the spirit of scientific innovation, take the market demand as the guide, and constantly promote technology research and development to help rural revitalization and ecological civilization construction. Zhengsai's success not only demonstrates the rise of China's science and technology, but also contributes Chinese wisdom to global environmental governance.Let us join hands to witness the gradual global promotion of Zhengsai's technology and contribute China's strength to the sustainable development of human society!
