Edible
Young leaves can be used as vegetables. In Guangdong, Guangxi and other places, Lycium barbarum buds are already very popular and can be bought in vegetable markets, but in the south, they are basically Lycium barbarum, and there is no Lycium barbarum in Ningxia. In northwest areas such as Ningxia, the tender leaves of Lycium barbarum are rarely used as vegetables.
Lycium barbarum is listed as a "dual-purpose medicine and food" variety by the Ministry of Health. Lycium barbarum can be processed into various foods, beverages, health wines and health products. Lycium barbarum is often added when making soup or porridge.
Seed oil can be made into lubricating oil or edible oil, and can also be processed into health care products and medlar oil.
Main value
Medicinal value
Fruit (called Lycium barbarum in Chinese medicine) has the same medicinal function as Lycium barbarum in Ningxia. Root bark (called Cortex Lycii in Chinese medicine) has antipyretic and antitussive effects.
Harvesting and processing: Lycium barbarum: June-165438+1October. Fruits should be harvested in batches. Spread fresh fruit on reed vines quickly, the thickness should be less than 3 cm, generally 1.5 cm, dry in the shade until the epidermis wrinkles, then expose to the sun until the peel becomes hard and the pulp becomes soft, and then remove the fruit stalks. Lycium barbarum leaves: picked from spring to early summer, washed and used for many purposes.
Main ingredients: Lycium barbarum contains betaine, atropine and betaine.
Lycium barbarum polysaccharide: Lycium barbarum polysaccharide is a kind of water-soluble polysaccharide, which is the most important active ingredient in Lycium barbarum. Its relative molecular weight is 68-200, and it has become a research hotspot at home and abroad.
Among them, the immunomodulation and anti-tumor effects of Lycium barbarum polysaccharide have been studied the most. Many studies show that Lycium barbarum polysaccharide has the functions of promoting immunity, anti-aging, anti-tumor, scavenging free radicals, anti-fatigue, anti-radiation, protecting liver and protecting and improving reproductive function. ?
Betaine: The chemical name is 1- carboxyl -N, n, N- trimethyl aminoethyl lactone, which is similar to amino acid in chemical structure and belongs to quaternary ammonium alkali substances. Betaine is one of the main alkaloids in the fruits, leaves and stems of Lycium barbarum.
The effect of Lycium barbarum on lipid metabolism or anti-fatty liver is mainly caused by betaine, which acts as a methyl donor in vivo. The research on Lycium barbarum betaine is limited to the domestic content determination, extraction technology and physiological effect on Lycium barbarum plants (enhancing salt tolerance), but the pharmacological effect of Lycium barbarum betaine is less. ?
Growth habit
Lycium barbarum likes cold climate and has strong cold tolerance. When the temperature is stable at about 7℃, seeds can germinate and seedlings can resist the low temperature of -3℃.
When the temperature is above 6℃ in spring, spring buds begin to sprout. Lycium barbarum overwinters at -25℃ without freezing injury. Lycium barbarum has developed root system and strong drought resistance, and can still grow in arid desert. In order to obtain high yield in production, it is still necessary to ensure water supply, especially in the flower and fruit period. The low-lying land with long-term water accumulation is not conducive to the growth of Lycium barbarum, and even causes root rot or death.
With sufficient light, the branches of Lycium barbarum grow healthily, with many flowers and fruits, large fruit grains, high yield and good quality. Lycium barbarum mostly grows in alkaline soil and sandy loam, which is most suitable for cultivation in deep and fertile loam.
