　　Dehua Pears are a new variety developed in 1996 by selecting and breeding from imported varieties such as Shinseiki pears from Taiwan. In recent years, due to the impact of global warming, flower buds of varieties such as Shinseiki pears in the southern part of the Daiyun Mountain range in Dehua County have been unable to go into proper dormancy during winter, resulting in significant yield reductions or even total crop failure. To address this issue, Dehua County conducted pear scion grafting trials. After the trials were reviewed and approved by the provincial science and technology department, the project was approved as a technology transfer initiative by the Ministry of Science and Technology of China. It received an interest-free grant of 700,000 yuan from the 2005 National Agricultural Science and Technology Achievements Transfer Project.

　　From December 1, 2005, to June 30, 2007, the Dehua County Crop Husbandry Center carried out comprehensive high-grafting variety replacement in project areas where the existing pear varieties were of low quality and poor economic returns. Measures taken included expanding planting pits to improve soil, orchard clearing, and applying formula fertilizers. The main variety, Shinseiki, was gradually replaced with a combination of Cuiguan, Xizi Green, Mixue, and Huashan pears. This created a well-balanced early, mid, and late-season variety structure, leading to a gradual improvement in varietal quality. A total of 5,090 mu (approximately 339 hectares) were improved over the two-year period.
