The first genetically modified salt-resistant poplar that can be used for field production, Zhongtian Yang, was successfully cultivated in Dongying recently. This is the first new species of salt-tolerant poplar tree obtained in China using genetically modified modern biotechnology. It has found a new way for the greening of saline-alkali land. According to reports, Zhongtian Yang is China's first salt-resistant, drought-resistant transgenic Yangshuo (Qingyang School) new species that was successfully developed by the Chinese Academy of Forestry and Shandong Agricultural University over a period of eight years. The test showed that: Poplar Zhongtian grows vigorously under soil conditions with 0.4% or less of salt content, grows normally from 0.4% to 0.6%, grows 2.6-2.8cm in diameter per year, and grows 1.6-1.9 cubic meters per mu per year. . The expert group of the Zhongtianyang appraisal committee, academician of the Chinese Academy of Sciences and academician of the Eurasian Academy of Sciences Zhang Xinshi, confirmed that the research results have reached internationally advanced levels in the salt-tolerance transgenic system and the breeding of salt-tolerant new varieties. Zhongtian Yang is not only resistant to salt and alkali, but also fast-growing. At the same time, it exhibits the characteristics of delicate green and green skin and beautiful tree appearance. At present, Zhongtian Yang has obtained the national patent protection rights for new varieties of plants, and the State Forestry Administration has also classified it as a fine variety of afforestation in the saline-alkaline arid regions and focuses on the promotion of new varieties.
