Fruiting is firm, and the phenomenon of pre-harvest fruit drop is small. This variety is productive, stable, high-quality, suitable for fresh food and juice, canning processing, wide adaptability, anti-cancer effect has been reported. Dongkui, also known as Dongao Dayang, giant plum, is the largest variety of domestic and foreign plum fruit.

Zhejiang Agricultural University and Chengjiang District Citrus Promotion Station from the local late-maturing varieties selected. Fruit color purple-red, single fruit weight 24.7g, maximum fruit weight 51.2g. sweet and sour taste, quality, containing soluble solids 13.4%, edible 92.8%.

Ding plain plum: originated in Wenzhou Chashan. ripe in late June, fruit purple-red, fruit stalk long, green tumor-like protrusion of the fruit tip, single-fruit weight of 15 ~ 18g, containing soluble solids 11.1%, edible 96.4%, top quality. Fruit fixation ability is strong, with stalk picking, more resistant to transportation. Zhejiang Linhai early big plum: for the maturity of the early large fruit-shaped varieties, quality is better. Place of origin matured in mid-June, single fruit weight 15.7g, maximum fruit weight 18.4g, containing soluble solids 11.0%, hard flesh, more resistant to storage and transportation, fruit picking and storage 1 day and night still maintain the original color of the fruit, is a very promising development potential of early varieties. One of the Linhai Xianju plum brand, in the line has been formed "the world plum in China, China plum out of Zhejiang, Zhejiang plum number Xianju" said.

Well-developed root system, strong absorption capacity, barrenness resistance, good productivity. But the resistance to plum cancer disease is weak, the introduction of seedlings should be strictly quarantine. Geographic distribution Yangmei native to China's temperate, subtropical humid climate of the mountainous areas, mainly distributed in the Yangtze River Basin to the south, north of Hainan Island, that is, between 20 degrees and 31 degrees north latitude, and citrus, loquat, tea tree, moso bamboo and other distribution is similar, but its ability to resist the cold is stronger than citrus, loquat. Mainly distributed provinces are Yunnan, Guizhou, Zhejiang, Jiangsu, Fujian, Guangdong, Hunan, Guangxi, Jiangxi, Sichuan, Anhui, Taiwan, etc., of which the cultivated area in Zhejiang is the largest, the quality of varieties is optimal, and the yield is also the highest. Followed by Jiangsu, Fujian and Guangdong. Abroad, such as Japan and South Korea have a small amount of cultivation, Southeast Asian countries, such as India, Myanmar, Vietnam, the Philippines and other countries also have distribution, but because of its small fruit shape, sour taste, more planted in the courtyard for ornamental purposes, or for candied food, not as an economic fruit tree cultivation. Therefore, Yangmei is the characteristic economic fruit of Zhejiang. Yield synthesis Yangmei tree sex strong and healthy, easy to cultivate, long economic life, the production cost is obviously lower than other fruits, therefore, is known as "green enterprise" and "money tree". The main production area of Zhejiang Lanxi Majian, Yuyao, Cixi water chestnut species of prunes, grafted seedlings, such as cultivation, generally 4 to 5 years to hang fruit, 8 years into the fruitful period, the plant yield of 50 to 80 kilograms, the high yield of large trees up to 300 kilograms, up to 500 kilograms, continuous planting of an average of 1,000 kilograms per mu, as high as 2,000 kilograms. Cixi City, three north of the town of Huang Guoyao farmers, contracted collectively 448 plants of prunes, in 1998 (small year) prunes production of 9,000 kilograms, income of 42,000 yuan.
