This project belongs to the field of forest cultivation technology, and is an integration and combination of multiple projects including the 11th Five-Year National Science and Technology Support Program of the Ministry of Science and Technology (MOST) entitled *Key Technologies and Demonstration for Restoration of Important Economic Bamboo Forests in Rain-Snow Freeze Disaster Areas*, the 948 Project of the National Forestry and Grassland Administration (NFGA, formerly State Forestry Administration) entitled *Introduction of Bamboo Micropropagation Technology*, the MOST Achievement Transformation Fund Project entitled *Research on Directional Cultivation Technology of Clumping Bamboo in Sichuan and Industrialization Demonstration*, the Forestry Science and Technology Project of the Forestry Department of Fujian Province entitled *Breeding of Excellent Cold-Tolerant Clumping Bamboo Varieties and Research on Tissue Culture and Rapid Propagation Technology*, the Sichuan Provincial Science and Technology Support Program Project entitled *Integrated Research on Modern Industrial Technology of Clumping Bamboo in Sichuan and Industrial Chain Demonstration*, and the Cooperative Project of Sichuan Provincial Industry-University-Research Innovation Alliance entitled *Research and Demonstration of Key Technologies for Cultivation of Rare Ornamental Bamboos in Sichuan*.

This project collected and sorted out the clumping bamboo resources in Southwest China, organized and completed the international registration of 7 new clumping bamboo varieties. Using molecular methods, it clarified the population genetic diversity of major clumping bamboo species in Southwest China, innovatively established a cold tolerance evaluation system for clumping bamboos, and screened out 23 clumping bamboo varieties with strong cold tolerance. It also established a comprehensive evaluation system for excellent clumping bamboo variety breeding, successively bred 13 excellent forest tree varieties of clumping bamboo, and extensively established clumping bamboo resource conservation nurseries and improved variety propagation nurseries, solving the problems of single variety and poor variety quality in clumping bamboo resource cultivation.

It solved the technical difficulties in traditional clumping bamboo seedling cultivation, formed a high-efficiency cutting propagation technology system, overcame the technical bottlenecks of adult bamboo tissue culture, and realized the industrialized production of clumping bamboo tissue culture. It established an intensive management technology system for clumping bamboo forests, and constructed a key technical system for emergency composite disaster rescue and restoration of clumping bamboo forests in Southwest China, filling the domestic technical gap in responding to major environmental disasters.

Improving product quality and processing technology is the core of the development of the clumping bamboo industry. By comprehensively using cultivation and biotechnology, the lignin content of main pulp-use clumping bamboos was reduced, and a new technology for quantitative hormone regulation of lignin was proposed. A number of new Liangshan Cizhu (Dendrocalamus farinosus) materials with low lignin content and high cellulose content were developed. Key technologies for high-value-added processing and utilization of bamboo fiber and high-purity lignin were formed, solving the common problem of low product added value. The "substitute wood with bamboo" pulping production process was optimized, the quality of bamboo pulp was improved, and resources were saved and efficiently utilized. The landscaping techniques and configuration modes of ornamental bamboos were studied, forming a theoretical system for bamboo plant design, which effectively expanded the application scope of bamboo plants.

It integrated the promotion system for directional cultivation technology of excellent clumping bamboo varieties and the industrialization model, explored an "Internet Plus" marketing and logistics model suitable for the bamboo industry. Relying on the construction of experimental and demonstration forests, it developed a "1234 Multi" industrial promotion model, "synchronous vertical and horizontal" promotion approaches, and a diversified bamboo industry development model suitable for Southwest China, which were applied and promoted in major bamboo-growing areas in Southwest China.
