赵洋与他的“蓝精灵”

Core Viewpoint - The research team at the Northwest Institute of Eco-Environment and Resources has developed a new technology for artificial biological soil crusts using desert cyanobacteria, significantly reducing the time required for desert stabilization from 15 years to as little as 3 years [1][5]. Group 1: Research and Development - The team has successfully created a composite material by mixing seven types of desert cyanobacteria with a substrate, which can grow into a crust when exposed to rainfall [1]. - Initial attempts to cultivate cyanobacteria in the field faced challenges, including the instability of the sandy surface and high costs of artificial irrigation [2][3]. - A breakthrough occurred when the team discovered that simulating natural rainfall could help cyanobacteria establish roots in the sand, leading to the development of a pressurized spraying method that improved efficiency and reduced costs [3][4][5]. Group 2: Innovation and Application - The successful application of the pressurized spraying method resulted in a survival rate of over 60% for the artificial crusts, with the time for crust formation significantly shortened [5]. - The team faced logistical challenges in remote areas where traditional spraying methods were impractical, prompting the development of a solid "seed" form of the cyanobacteria for easier transport and application [6][7]. - The solid inoculum technology has been integrated into the new "Three-North" project, aiming to restore 80,000 to 100,000 acres of desert over the next five years [8]. Group 3: Future Prospects - The research station is capable of producing 5 tons of dry cyanobacteria powder annually, which can restore approximately 5,000 to 7,000 acres of desert land [8]. - The team aims to expand the application of the cyanobacteria crust technology beyond Ningxia, providing a Chinese solution for global desertification issues [8][9].
