Ramie seedling technology has achieved new breakthroughs

Recently, during the observation ceremony of the "Nettle Young Shoot Hydroponic Industrialized Seedling Technology System" organized by the Institute of Materia Medica of the Chinese Academy of Agricultural Sciences, it was revealed that traditional ramie shoot soil cutting methods have significant environmental impacts and are highly labor-intensive. These techniques face challenges such as high labor costs and low land utilization efficiency. To address these issues, a research team led by researcher Xiong Heping at the Hemp Research Institute has developed an advanced hydroponic seedling technology system for ramie shoots. This innovation has streamlined and simplified the nursery process, significantly improving resource use efficiency in agriculture.

The new technical system employs water-based cultivation methods involving disinfection procedures, nutrient solution formulation, controlled light and temperature environments, variety-specific characteristics, and optimal planting density. It also includes hydroponic growing modes that allow for easy transportation and adaptation, laying the groundwork for mechanized ramie planting. By eliminating soil-borne diseases, this system effectively boosts the survival rate of ramie cuttings, achieving a 92% survival rate after field transplantation. Additionally, it transforms the traditional seasonal soil cutting approach into a year-round, continuous seedling production method. This not only shortens the growth cycle but also enhances the efficiency of water and soil resource use while improving working conditions and reducing labor demands significantly.

At the observation meeting, hemp experts praised the hydroponic seedling technology for integrating the benefits of facility management, vertical farming, and off-season production. They highlighted its potential to meet the needs of modern agricultural industrialization, which requires large-scale and continuous output. Experts recommended increasing government funding for long-term support, further refining the technical parameters, and establishing a demonstration plant for castor hydroponics as soon as possible. These steps could drive the overall development of China's ramie industry and promote sustainable agricultural practices.
