The experiment of introducing black wolfberry in our province was successful.

SciDev.Net (Reporter Fan Guangnian) recently, 300 mu of black wolfberry planted in the suburbs of Shijiazhuang are in full bloom and full of fruit. This is the field performance of wild black Lycium barbarum seedlings introduced from Qinghai by the Medicinal Plant Research Center of the Institute of Economic crops, Hebei Academy of Agricultural and Forestry Sciences.

Black wolfberry (Lycium ruthenicumM urr.) It is a perennial shrub of Lycium barbarum of Solanaceae, with a height of 20cm and 250cm. Much branched, the branches are hard, often curved in the shape of a zigzag. The leaves of black wolfberry are lanceolate and fleshy, with purple flowers and self-pollination. The roots of adult trees are more than 200cm into the ground. They are drought-resistant, cold-tolerant, saline-alkali-tolerant, and can withstand 38.5 ℃ of high temperature. The extreme temperature in winter grows well in the area where the extreme temperature is-28 ℃, and the soil requirements are not strict, but the waterlogging resistance is poor. At present, black wolfberry for medicine and health care in China mainly comes from wild species. It grows in Qinghai Chaidamu Basin and the surrounding Gobi Desert, and its natural growth environment is relatively harsh.

Black Lycium barbarum can be called "soft gold". It is rich in anthocyanins, polysaccharides, organic acids, free amino acids, selenium and vitamins C, B1, B2 and other nutrients, and its medicinal health value is significantly higher than that of red wolfberry. It has the effects of cleaning free radicals, anti-oxidation, improving immunity, reducing blood sugar, anti-fatty liver, anti-atherosclerosis and so on. Black Chinese wolfberry anthocyanin (red Chinese wolfberry does not have), its oligomeric proanthocyanidins (OPC) content is higher than blueberry (black Chinese wolfberry contains OPC3690mg/100g, is more than 22 times of blueberry content, is a high-grade health care products raw materials, the market price is not cheap. As a result, predatory mining occurred in the origin, and the wild black wolfberry resources were seriously damaged. In order to protect wild Lycium barbarum resources, the introduction experiment was conducted in our province in 2014.

After the introduction of black wolfberry, multi-site experiments were conducted in the plains and mountainous areas of our province. It was observed that the average annual branch growth of Lycium barbarum was more than 50 cm and could form 3-6 branches, and its growth, plant growth, flowering and fruiting ability were obviously better than those of origin. Xie Xiaoliang, an expert at the chief post of traditional Chinese medicine in Hebei Province, said that black wolfberry blossomed in the same year when it was planted. In the plain area, it generally began to blossom in May and bear fruit in June. At the end of June, the first fruit matured one after another, the branches blossomed for the second time in August, and the second fruit was formed in September. The cultivation and management of black wolfberry is very simple, and there are few diseases and insect pests. 1-2-year-old young trees pay attention to pruning the weak branches at the bottom and cultivate 1-2 central backbone branches to form the trunk. With the growth of the plant, it is generally cultivated into a trunk type multi-layer umbrella crown, which is convenient for future picking and management.

The appearance and internal quality of artificially cultivated black Lycium barbarum fruit in our province is better than that of wild Lycium barbarum. Detected by the Medicinal Plant Research Center of Hebei Academy of Agricultural and Forestry Sciences, the indexes of water, polysaccharide, anthocyanin (sunflower pigment), betaine, citric acid and selenium in dried fruit were higher than those in wild Lycium barbarum L..

The introduction experiment shows that black wolfberry can be planted in the mountain area and plain of our province. The yield of dried fruit is 3 kg per mu in the same year, 30 kg per mu in 2 years and 80 kg in 3 years. It is estimated that the dry fruit yield per mu in the high yield period is more than 200 kg, and the economic benefit is remarkable.

It is understood that black Chinese wolfberry generally does not get sick, does not catch insects, and is easy to manage. It only needs pruning, fruit picking and drying. The planting density is 440-660 plants per mu, and the row spacing is generally 200 cm × 70 cm.
