Propagation methods of Lycium barbarum

Lycium barbarum L. is mainly propagated by seeds, and can also be propagated by cuttings.

(1) Seed breeding

① Seed selection and treatment: select plants with strong growth, big red fruit, no diseases and insect pests, more than 6 years old as seed mother plants, and pick them in time when the fruit is red from June to November. The picked fruits are soaked in warm water at 30~35℃ for 24 hours, taken out and kneaded, and the seeds are washed out in clean water. Remove the flesh and peel, take out the mature and plump seeds that sink to the bottom, and sow them after drying. If not sown immediately, 1 part of seed mixed with 3 parts of wet sand evenly, put into a wooden box, placed in 20℃ indoor stratification germination, the next spring to have 30%~50% of the seeds crack white, take out sowing.

② Sowing: Sowing can be carried out in spring, summer and autumn. Sowing in late March in spring is best. On the tidied nursery bed, transverse sowing furrows are opened according to the row spacing of about 25 cm, the depth of the furrows is 2~3 cm, and the sowing width is 5 cm. Then the seeds are evenly scattered into the furrows, covered with fine soil after sowing, slightly compacted, and the bed surface is covered with grass for heat preservation and moisture preservation. 150~200 grams per 667 square meters.

③ Seedling management: watering frequently after sowing to keep the soil moist. To facilitate seed germination and seedling growth. After the seedlings emerge, remove the grass covering the ridge, then carry out intertillage and weeding for 4~5 times, combine intertillage and weeding to thin the seedlings, pull out the weak seedlings when the seedling height is 5 cm for the first time, and keep the seedlings according to 5~6 cm; for the second time, remove the weak seedlings and keep the strong seedlings according to 10~15 cm in the first and middle of July. At the same time of thinning and fixing seedlings, thin human and animal feces and urine were applied every 667 square meters to promote the growth and health of seedlings. When the seedlings grow to 30 cm high, the lateral branches at the base of the seedlings should be removed in time, and the seedlings should be topped when they are 60 cm high to accelerate the growth of the trunk and the main lateral branches. Spring seedlings can be planted out of the nursery after autumn, summer and autumn seedlings in winter irrigation once sealed ice water, the next autumn out of the nursery planting.

(2) Cutting propagation

selecting plants with large fruit, high yield and good quality before the plants germinate at the end of spring, cutting one-year-old branches with the diameter of 0.5 cm, cutting into cuttings with the length of 15 - 20 cm, quickly soaking the lower ends of the cut with 0.05% rooting powder or 0.05%-0.1% indophoric acid solution for 10 - 15 seconds, and drying the cuttings. Cuttings, in the whole good nursery ground on the ridge surface according to row spacing 40 cm ditch, ditch depth 15~20 cm, with plant spacing 10 cm cuttage, cuttage exposed soil surface about 1 cm. After planting, set up a shed to shade, keep the seedbed moist frequently, strengthen intertillage and weeding, apply fertilizer appropriately, and plant seedlings when they are 80 cm high.
