There has been a lot of rain recently, which is a good time for afforestation. As the most precious wood in China and the only redwood tree species that can grow outdoors in Zhejiang Province, Dalbergia odorifera has a good development prospect in some areas of Pingyang County. On the basis of selecting afforestation sites with better site and habitat in the early stage, Wenzhou Science and Technology Commissioner and Zhejiang Subtropical Crops Research Institute Li Xiaowen newly planted more than 3,500 container seedlings of 2-3 year-old Dalbergia odorifera, a good cold-resistant variety cultivated by the institute, at Shipaiyue Family Farm in Mabu Town of Pingyang County and Fuweige Family Farm in wanquan town, totaling 32 mu. At the same time, according to the requirements of Wenzhou local standards, high-standard afforestation and dry cultivation are carried out. Among them, Fu Weige’s family farm in wanquan town planted Dalbergia odorifera in the rape field planted last year to make full use of the light conditions in the early stage of afforestation, and planted 5 mu of warm turmeric in the open space under the forest.
It is reported that since 1976, the provincial Asian Research Institute has successfully introduced Dalbergia odorifera in Ouhai, Wenzhou, which can grow in the winter outdoors, naturally breed and pass the heartwood quality test. It is the northernmost area reported in the literature that Dalbergia odorifera has been successfully introduced. The precious tree species team of this institute has made a series of achievements in cold-resistant seed selection, seedling breeding, afforestation tending and comprehensive utilization technology of Dalbergia odorifera. In 2022, its selected “Wenzhou Dalbergia odorifera mother forest seed” (Zhejiang S-SS-DO-003-2021) was approved as a provincial-level cold-resistant seed, and it can be planted in a sunny place with extreme temperature above -4℃. As a science and technology correspondent in wanquan town, Li Xiaowen, an associate researcher, guided Kegang Family Farm in Pingyang County to introduce and plant more than 40 mu of Dalbergia odorifera in 2018-2019. Under the scientific guidance and careful management, the rice diameter has now increased to 5-8cm, and some plants have accumulated red heartwood substances. At the same time, in order to make full use of the forest land and guide the farm to plant Polygonatum sibiricum, Anoectochilus roxburghii and other precious Chinese herbal medicines under the forest, it has been guided and highly appreciated by the leaders of provincial, city and county forestry authorities for many times, and has achieved a good scientific and technological demonstration and leading role, truly achieving “storing wealth in the forest and storing wealth in the future”. It is of great practical significance to promote the construction of rural areas in the United States, promote the common prosperity of urban and rural areas and practice the concept of “Lucid waters and lush mountains are invaluable assets”.
