Aiming at the problems in plain forestry development in Jiangsu, such as the decline of woodland productivity in planted forests and low utilization rate of understory resources, this project broke through technical bottlenecks of traditional agroforestry, including single function, low level of scaling and industrialization, and carried out integrated innovation, demonstration and popularization of key technologies for efficient agroforestry management in Jiangsu planted forests according to local conditions.

1. Optimize Efficient Agroforestry Management Models for Planted Forests
Based on a comprehensive investigation of the existing agroforestry management models, crop compositions and main functions of planted forests in Jiangsu, the existing models were optimized and allocated according to the principles of combining efficiency and marketability, and balancing scientificity and practicality. Five efficient agroforestry management models were formed, including intensive forest-medicine composite model, dual-chain forest-animal-poultry composite model, circular forest-fungus composite model, integrated forest-seedling composite model and ecological forest-tea composite model, which effectively promoted the scaling and industrialization development of agroforestry in Jiangsu planted forests.

2. Study Interspecific Regulation Technologies for Planted Forest Agroforestry Systems
Aiming at the eco-economic objectives of planted forest agroforestry management, this project systematically studied interspecific water competition, light energy regulation, soil physical and chemical properties, carbon sequestration capacity and dynamic changes of landscape pattern in planted forest agroforestry systems, which laid a theoretical foundation for innovating key technologies for efficient planted forest agroforestry management.

3. Innovate Key Technologies for Efficient Planted Forest Agroforestry Management
Based on the current status of planted forests and understory resources in Jiangsu, 8 key technologies for planted forest agroforestry management were integrally innovated, including new afforestation of planted forests, high-efficiency matching technologies for forest-animal-poultry agroforestry, using black light traps to attract insects for free-range chicken farming in closed poplar stands, efficient utilization of wood processing waste for edible fungus cultivation, intensive cultivation for forest-medicine agroforestry, ecological planting for forest-tea intercropping, sustainable integrated management for forest-seedling systems, and integrated pest management for poplars. These technologies broke through the technical bottlenecks of traditional agroforestry, such as single function and low benefit.

4. Establish Demonstration Bases for Efficient Planted Forest Agroforestry Management
According to the regional characteristics of Jiangsu, 8 demonstration bases for efficient planted forest agroforestry management were established in Liyang (southern Jiangsu), Hanjiang (central Jiangsu) and Pizhou (northern Jiangsu), which set a benchmark for the comprehensive radiation and popularization of agroforestry models and technologies in Jiangsu planted forests.

Through project research and technical demonstration, 15 improved tree varieties were certified, 5 local agricultural standards were formulated, 10 national invention patents were obtained, 1 monograph was compiled, 1 planning document was developed, 2 research reports were compiled, and 18 academic papers were published. Upon novelty search and achievement appraisal, the overall achievements of this project reached the domestic leading level, with some technologies reaching the international advanced level.
