Core Viewpoint - The article highlights the successful cultivation of highland forage grass using aerospace breeding technology in Tibet, showcasing its resilience in harsh conditions and potential economic benefits for local farmers [1][2][3]. Group 1: Aerospace Breeding Technology - Seven new varieties of forage grass have been developed using aerospace mutation technology, demonstrating exceptional salt and drought resistance, as well as the ability to withstand temperatures as low as -40 degrees Celsius [1]. - The last experimental variety of protein grass, transplanted on July 17, shows rapid growth, reaching heights of 2.5 meters and an expected yield of 15-25 tons per acre [2][8]. Group 2: Economic Impact - With an estimated yield of 15 tons of forage grass per acre, and considering a dehydration rate of 70%, the potential economic benefit is around 8,000 yuan per acre annually, based on a market price of 1,200 yuan per ton [3]. - The local community is engaged in the cultivation process, indicating a positive impact on employment and local economies [7]. Group 3: Selection and Evaluation Process - The selection process for these varieties involves rigorous testing to ensure stability and unique potential in terms of salt and alkali resistance, yield, and plant morphology [6]. - After returning from space, the seeds undergo a three-year evaluation period to assess their yield and quality before they can be fully utilized [8]. Group 4: Future Plans - The team plans to continue monitoring the growth of the aerospace-bred plants and promote the technology for both forage and vegetable cultivation, alongside establishing an organic fertilizer factory to improve soil quality [10].
