Experience of Cuttage Propagation of Lycium barbarum L.

What is northern Chinese wolfberry?

Northern Chinese wolfberry (Lycium potaninii Pqark.), also known as northwest Chinese wolfberry, is a wild fruit tree distributed in Northeast China, Inner Mongolia and other places. Its fruit is used for both medicine and food, and has the outstanding characteristics of cold resistance, drought resistance, early fruit, high yield and so on. At present, large fruit type strains have been selected from wild resources, which can also be used for wind prevention, sand fixation or greening and ornamental in addition to artificial cultivation in a large area.

Experience of Cuttage Propagation of Lycium barbarum L.

1. Hardwood cuttings. Hardwood cuttings were carried out in the first and middle of April. Set up a hot Kang or electric hotbed before cutting. Before the end of March, the seed strips were obtained combined with winter pruning, and the seed strips were cut into 15~17cm cuttings, soaked in 150mg naphthylacetic acid at the base of 5cm for 24 hours, washed with clean water and inserted into the hotbed, the plant spacing was 5 × 10cm, the cutting depth was 15~17cm, and the temperature at the base of cuttings was kept at 28030 ℃. The rooting began 25 days after cuttage, and the rooting stage ended 35-40 days after cutting. The average rooting rate of cuttings is 85%, with a maximum of 95%. It moved into the nursery for management in the first and middle of June, and the seedlings grew in the same year, and the robust ones could blossom and bear fruit.

2. Softwood cutting. Softwood cuttings were carried out in late June. Set up a plastic shed (or use an existing plastic greenhouse or greenhouse) before cutting, and use a sunshade net on the outside or inside of the plastic shed to make the light transmittance about 30% of the natural light. The cutting bed with wide 150~200cm and high 25~30cm was made with fine river sand in the shed. The semi-lignified shoots were collected and cut into cuttings with long 10~12cm. The leaves at the base 5~6cm were removed and the upper leaves were retained. The cuttings were quickly dipped in 1000~2000mg solution of rooting powder or naphthalene acetic acid and then cut. The row spacing of cuttings is 5 × 10cm, the cuttings are perpendicular to the bed, and the cutting depth is 5~60cm. Spray water with a small eye pot at 8: 16 every day after cutting to keep the cuttings leaves moist, the relative humidity in the greenhouse above 80%, and the temperature 30: 35 ℃. The cuttings began to take root 20-30 days after cutting and transplanted to the field 40 days later. The average rooting rate of tender wood cuttings is about 80%, up to 95%; the survival rate of transplanting can reach 90%, and seedlings can be formed in the same year.

Analysis of planting projects of Lycium barbarum

Chinese wolfberry is not only a good tree species for soil and water conservation, but also an important traditional Chinese medicine. It is covered with treasures, and its leaves, fruits and skins can be used as medicine. In recent years, with the development and utilization of nourishing drugs and food, the market demand of Chinese wolfberry has increased sharply. In addition, the existing Chinese wolfberry cultivation is sporadic, the management is extensive, the output is low and unstable, the market demand of Chinese wolfberry is in short supply. In order to meet the needs of the market, growing Chinese wolfberry is economical, simple and easy, and is expected to expand cultivation.

Lycium barbarum is a deciduous shrub, more than one meter high, with grayish yellow stem bark, thin branches, often bent and drooping, short lateral branches, and often become short thorns in leaf axils. Leaves rhombic-ovate or ovate-lanceolate, 1.5 li 5 cm long, flowers lavender. Berries bright red, ovoid or oblong, seeds mostly flat-reniform, yellowish, 2.5 mm long. The florescence is 9 months, and the fruit is ripe from August to October.

Light-loving, drought-resistant, cold-resistant and alkali-resistant, it can grow on loess cliffs and the edge of sand wasteland. Produced in the south of Liaoning, north of Yunnan, east from Taiwan, west to Gansu, is a widely distributed tree species, with the most famous cultivation in Zhongning area of Ningxia with a long history. The main excellent varieties are hemp leaf wolfberry, small hemp leaf wolfberry.

Field management of Chinese wolfberry

1. Weeding in mid-tillage should be carried out in time to prevent weeds from competing with plants for fertilizer.

2. Topdressing 3 times at seedling stage, applying urea 7kg / mu each time. After planting, in the blooming and fruiting period, the phosphate plating compound fertilizer was applied twice, and the plant was applied 20g / 100g. From late October to early November every year, a circular ditch was opened on one side of the root to apply organic fertilizer, cover the soil and water.

3. After irrigation and planting, the new branch growing period and flowering and fruiting stage were irrigated once every year from May to June, after fruit harvest in August and in the first ten days of September. From October to November, the combination of topdressing and reirrigation of frozen water. Avoid excessive dampness and poor drainage.

4. The newly planted Lycium barbarum seedlings were fixed to dry when the dry height was 60 cm, and 3-5 lateral branches were selected. In the second year, the selected 3-5 lateral branches were retracted to 30 cm to form the first crown. In the third and fourth year, the overgrown branches on the backbone branches of 2-3 layers were cut short at 20 cm, and the upper crown was gradually formed. After several years of plastic crown formation, withered branches, old and weak branches, disease and insect branches and overlapping branches were cut off every autumn or summer. If bonsai is made, it can be inserted into a sturdy branch shearing rod before germination in the spring of the second year, and it will blossom and bear fruit in the coming year.

5. the main diseases of common diseases and insect pests are black fruit disease, root rot, etc., and the main insect pests are fruit fly, Guoe, niece and so on.

With the continuous development of the rural economy, the planting industry is also developing very well in the rural areas of our country, the threshold of the planting industry is low, and the investment risk is relatively much less, so now a lot of farmers have begun to grow a variety of agricultural products. The rural economy of our country has also been developed as a whole.
