The project focused on the evaluation of suitable sites for important industrial raw material forest tree species such as Ginkgo, Eucommia, Tung, Litsea cubeba, Lacquer, Taxus, Moringa, Liquidambar, Camptotheca acuminata, etc. Significant progress has been made in research on technologies such as cultivation and high-value resources and deep-processing. (1) The main factors affecting the yield and quality of industrial raw material forest tree species were identified, and 4 suitable site conditions evaluation models for main industrial raw material forest tree species such as ginkgo, eucommia, tung tree, litsea cubeba, and lacquer were established. Eucommia, Tung oil, Litsea cubeba, and sumac cultivation areas and non-suitable areas. (2) The key factors affecting the grafting survival, cutting rooting and tissue culture of Ginkgo biloba, Eucommia ulmoides, Tung tree, Litsea cubeba, sumac, and yew were determined, and 15 technical procedures were developed. (3) The key factors of high-quality and high-efficiency production technology of main industrial raw material forest resources were determined, and the relationship between various technical measures and the production and quality formation of main industrial raw material forests was revealed. 8 standards were developed or promulgated, and the output increased by more than 20%. Different mechanical equipment such as leaf picking, fruit picking, fruit dehulling, and resin harvesting are designed. The harvesting efficiency of industrial raw material forests is increased by more than 3 times, and the harvesting cost is reduced by more than 50%. (4) Established 14 sets of high-value key technologies such as low energy consumption, high efficiency, green extraction and purification of target active small molecules of industrial raw material forest tree species, preparation or extraction of target polymers, production of derivative products, comprehensive development and utilization of resources, etc., developed or promulgated There are 7 product quality standards.
