The 2022 annual summary meeting of the national key R&D plan project "Key Technologies for Obstacle Reduction and Quality Improvement and Capacity Improvement in Medium and Low-yield Rice Fields" was held

On January 16, the Institute of Subtropical Agroecology, Chinese Academy of Sciences organized the 2022 annual summary meeting
of the national key research and development plan project "Key Technologies for Obstacle Reduction and Quality Improvement and Capacity Improvement in Medium and Low-yield Rice Fields".
Professor Tan Wenfeng of Huazhong Agricultural University, researcher Zeng Xibai, Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences, researcher Zhang Wenju, Institute of Agricultural Resources and Regional Planning, Chinese Academy of Agricultural Sciences, and Wei Wenwen, researcher of the Institute of Subtropical Agroecology, Chinese Academy of Sciences, attended the meeting and served as commentators
.
More than 40 people, including Director Liu Shoulong of the Science and Technology Management and Planning Department of the Institute of Subtropical Ecology, researcher Wu Jinshui, project leader, sub-project leaders and project backbones, attended the meeting
.
The conference was conducted in a combination of online and offline mode, chaired by researcher Wu Jinshui
.

At the meeting, Wu Jinshui made a report
on the subject tasks, expected results and assessment indicators, task decomposition, experimental progress, achievement outputs, and funding.
The leaders of the five sub-projects reported
on the specific implementation plan and research progress of the technical model of reducing obstacles and capacity improvement in latent and infertile low-yield rice fields.
The Advisory Expert Group conducted in-depth discussions and comments on the details of the implementation plan, task setting and experimental progress of each sub-topic, and put forward suggestions
.
Tan Wenfeng affirmed the achievements made by the project since its implementation for more than a year, and pointed out that the project focuses on the analysis of the improved technical mechanism and model construction of the middle and lower reaches of the Yangtze River, and the proposed technical model should strengthen the cost calculation of benefits, be able to be popularized and demonstrated and applied, and form standards
.
Wu Jinshui said in his concluding speech that he will seriously absorb and understand the opinions of experts, optimize and adjust the implementation plan of the project, strengthen the excavation of bright spots and innovative work, accelerate the exchange and integration between various sub-topics, and promote the efficient implementation of
the project.

This meeting summarized and sorted out the problems existing in the current stage of the plan, and refined and adjusted the project implementation plan in a targeted manner, laying a solid foundation
for the implementation of subsequent projects.
The implementation of this project will eventually form a technical model for the reduction of reducing substances in latent paddy fields, the construction of thick fertile cultivation layers in barren farmland and the directional cultivation of biofertility, which will provide important solutions for the reduction of obstacles and productivity improvement of low- and medium-yield paddies in the middle and lower reaches of the Yangtze River, which is of great significance
to ensure China's food security and increase farmers' income.
