Extended knowledge: Prunus mume, also known as green sepal plum, is named after its green calyx, white flowers and green branchlets. In the classification system of plum varieties, it belongs to the green calyx type of true plum and is the best among plum strains. I like high air humidity, certain drought resistance, and not strict requirements for soil. However, sandy loam, which likes humidity and is rich in humus, is easy to rot and die when the soil is sticky and the drainage is not smooth.
Small deciduous trees, up to 10 m. The trunk is purplish brown with many longitudinal stripes. There are often thorns, and the branchlets are green or green as the background color. Ye Guang is ovoid to ovoid with a long cone or tail tip at the top. In early spring, the leaves open first in February-March, and peanuts are solitary or clustered in the axils of annual branches, solitary or reborn, with a dark fragrance. Drupe is spherical, with shallow groove on one side, hairy, ripe in June and yellow when ripe. Branchlets are green and have no purple halo.
Common plum diseases and insect pests are more likely to occur on Gongfen plum and Zhusha plum, but less likely to occur on Green Calyx plum. In addition, the survival rate of bud grafting is much higher than other varieties because of its strong growth, strong new branches and full leaf buds. However, Prunus mume also has its shortcomings, that is, the frost resistance of buds is poor, so we should pay attention to cold protection in Ducrey when the cold wave comes.
Be distributed
Originated in Southwest China and Taiwan Province Province, mainly produced in Jiangsu, Zhejiang, Sichuan, Hubei, Jiangxi and other places. "Xiang Xuehai dares to produce ten thousand flowers, and the world is the first tree in spring." Plum blossom has always been regarded as a symbol of being fearless of violence, stronger than struggle, loyal and noble. The ancients often matched pine, plum and bamboo into "three friends who are cold in the old age".
growing environment
Hi-light, suitable for sunny and well-ventilated environment. I like warm climate, but I am cold-tolerant.

Study on the new technology of microwave inactivation and drying of green sepal plum
Taking alcohol-soluble extract, chlorogenic acid, hyperoside and isoquercitrin as evaluation indexes, fresh plums were dried by microwave, and the effect of microwave drying on the quality of plums was discussed. Results: The microwave drying process was optimized. The content of chlorogenic acid in microwave dried samples was higher than that in traditional dried samples, and the difference was significant.
Conclusion: As a new processing method, microwave drying can effectively preserve the effective components of green sepals and improve the product quality of green sepals.
Antidepressant effect of Prunus mume extract on mice
In vivo efficacy evaluation methods such as tail suspension test (TFT) and forced swimming (FST) were used to observe the therapeutic effects of ethanol extract and water extract of ebony on depression model mice. Results The ethanol extract of ebony can obviously shorten the tail suspension time and forced swimming time of mice (P
