Dewey Wendan pomelo has a long history of planting. According to legend, Wu Yu 1833, a member of Houting Formation in Tanbian Village, Dewey Town, Xianyou County, was admitted to the middle school. The next year, he visited Jinhua Prefecture, Zhejiang Province, and tasted the local grapefruit with friends. He felt that the quality was good, and even asked local friends for grapefruit seedlings and brought them back to his hometown for planting. After several years of careful cultivation, pomelo trees have grown sturdily. The yellow-green fruit weighs about 2 Jin. It tastes good when it is picked, but there is little residue in the juice. There are many grapefruit seeds in the pulp. The shape of fruit is irregular, and the thickness of peel affects the quality. Wu felt that the quality of the grapefruit he planted and the grapefruit eaten by Jinhua had obviously deteriorated. At a friend's party, Wu learned that there was a young woman named Wu Jiemu in Tanbian Village. She is handsome and beautiful, and she is also a famous dancer of Putian Fairy Troupe. A few years ago, when she went out to perform, she brought back a grapefruit seedling and planted it on her side. It has blossomed and borne fruit. Its quality is excellent, not only the taste is good, but also the fruit is not big, only about half a catty. When two people taste each other's grapefruit, they think that only by combining the advantages of both sides can they achieve good quality. Therefore, fruit manufacturers are required to cut pomelo ears from the pomelo trees planted by Wu Jiem and graft them on Wu's pomelo trees. After careful management, the newly grafted pomelo tree finally bears fruit. When harvested at the end of 10, the fruit weighed 65,438+0.5-2 Jin, which looked very heavy, with a bluish yellow color and high yield. When tasting endosperm, it has the advantages of both. It is fragrant and refreshing, juicy and tender, seedless and residue-free, and fragrant, which is a good product in pomelo. After that, they carefully cultivated and constantly bred this excellent variety and gave it to relatives and friends for planting. A few years later, this kind of grapefruit was planted sporadically in several natural villages such as Baoxing, Xincuozi and Chenku in Dewey Town. At that time, because the output of this kind of grapefruit was very small, it was mostly presented to relatives and friends, bosses, VIPs and even as a tribute to the court by the local government. [After successful cultivation in the late Qing Dynasty, the masses raised seedlings by high pressure and spread them to neighboring villages. 1949, Tuwei Wendan pomelo output Figure 2 Tuwei Wendan pomelo planting base
