Wellingxian (northeast clematis). 

Northeast clematis. 

Clematis in Northeast China is a perennial herbaceous plant of Clematis genus in Ranunculaceae, which is widely distributed in three provinces of Northeast China, namely Wellingxian, wild pepper seedling, mountain pepper seedling and Polygonum polygonum Clematis. Authentic Wellingxian includes northeast clematis, cotton clematis and Wellingxian. The roots and rhizomes of three kinds of plants are mainly used for the treatment of rheumatism arthralgia, unfavorable joints and so on. Pharmacological studies have shown that Weilingxian has strong anti-inflammatory, analgesic, anti-tumor activities.

Medicinal value. 

Medicinal value. 

The northeast clematis is warm, pungent and salty, and has the effects of removing rheumatism, dredging channels and collaterals, relieving pain and removing bone choking. It is often used in the treatment of wind, cold and dampness arthralgia, joint disadvantage, limb numbness, tonsillitis, esophagus cancer and other diseases. Clinically, it is mostly used for anti-inflammatory and analgesic, relaxation of smooth muscle, anti-tumor treatment and the treatment of limb numbness, immunosuppression, adverse flexion and extension and other symptoms. 

The traditional Chinese medicine Wellingxian is the dry root and rhizome of Clematis in Ranunculaceae, Clematis or Clematis in Northeast China. It is accustomed to traditional Chinese medicine, taste salty, warm, toxic, with the effect of dispelling wind and dehumidification, dredging collaterals and relieving pain. Since ancient times, there have been records of the application of Wei Ling Xian in the treatment of diseases: "the sea test square" Yan Wei Ling Xian "to the wind, through the twelve meridians"; "Taiping Sheng Hui Fang" Wei Ling Xian liquor can be treated "waist and foot pain for a long time." "Materia Medica Justice" carries "Wei Lingxian, to walk and eliminate the gram for the ability, accumulation of dampness to stop phlegm, blood coagulation qi stagnation, all really appropriate." The Compendium of Materia Medica also records that the prescription made by Wei Ling Xian can be used to treat "stopping phlegm and drinking, wheezing cough and vomiting", and in "Anticancer and Therapeutic Materia Medica", it is said that Wei Lingxian can "fight cancer and defeat poison" and so on. 

Beautification value. 

In August, the plant is full of white flowers from top to bottom, and between each node there are several to more than ten flowers blooming, long and warm, showing its enthusiasm on a hot summer day. If planted on flat ground, it will be a white carpet; if you make hedges, corridors, flower racks, arches, it shows you clusters of white flower walls and unique climbing styles, so the northeast clematis is also an excellent landscaping plant. 

Seedling propagation method. 

Sowing and seedling raising. 

Preparation of seeded beds. 

From early October to early November or early April of the following year, sandy soil to medium loam flat plot was selected to remove sundries from the surface, evenly sprinkle farm fertilizer on the surface, apply 3 000 to 4 000 kg per mu (667m2, the same below), turn the ground deep and break the soil blocks. According to 1.2m wide, 0.15m high, 10 to 25m long to make the north-south or other directions of the bed, beat the edge of the bed. 

Fruit picking and seed treatment picked fully mature achenes at any time in July and August, accumulated and dried for 3 to 5 days, picked up sundries, cleaned up seeds and dried them. In the middle and late January, the seeds were soaked in water at 20-25 ℃ for 24 hours, and the seeds were fully mixed with 3 times river sand. It was best to mix a small amount of 50% carbendazim powder in advance, and the water content of sand was 25% to 30%. The planting sand was bagged at 2 ℃ to 7 ℃. The planting sand was taken out in the first ten days of April and could be sown when the seeds germinated. If the seeds do not germinate, they can be dried in the sun and germinated after 3 to 5 days. 

Sowing. 

In the middle of April, the deep ditch of 2cm was opened along the bed or across the bed, and the distance between the ditch and sand was 12 to 15 cm. The seed distance was 3 to 5 cm, the sowing rate per mu was 3.5 kg / mu, and the cover soil thickness was about 1cm. It can also be sown at the beginning of November. In this period, the seedling emergence is early and the seedling growth is large, but if there is no snow in winter or drought in early spring, the emergence rate is very low. 

Post-broadcast management. 

After sowing in spring, the bed was evenly sprinkled with phoxim and methyl tobuzin at the dosage of 1.5kg/100m2 and 0.5kg / 100m2, respectively, in order to prevent mole cricket from turning over the bed and avoiding seed decay. Then cover the bed surface with 1~1.5cm thick peat soil or fine broken leaves and finally spray water on the cover and wet the bed surface 6~10cm deep. The bed weeds are pulled out at any time in the growing season to ensure that the seedlings are not damaged by the grass, and if the disease is found in June and August, the seedling can be sprayed with 10% antibacterial agent 401 acetic acid 1000 times. It is found that there are red spiders and aphids, which can be controlled by spraying 800 to 1000 times of fenitrothion EC. From late October to early November, if the bed surface is dry, it should spray enough frozen water to the bed surface. 

Cutting seedling. 

Selection of cuttings and cutting of cuttings. 

In June and July, the harder shoots with thickness above 3mm were cut from more than 4-year-old plants, the cuttings were cut according to the length of 6~8cm, the leaves and petioles in the lower half of the cuttings were cut off, and the top leaves were retained. The axils of the leaves should have fuller buds or young shoots that have just grown. 

Cuttings dipped in rooting agent. 

The 2cm at the base of the cuttings was dipped in the solution of indolebutyric acid or indoleacetic acid with the concentration of 25~50mg/L for 24 hours. 

Plug in bed preparation. 

Cut the ear at the same time or prepare the bed two days ago. The width of the bed is 1.0 to 1.2 m, the height of the bed is 0.10 to 0.15 m, and the length of the bed is 10 to 25 m. The bed is built with vertical brick around the bed, and the matrix material in the bed is 12~15cm thick coarse river sand mixed with the same amount of grass carbon soil or fine river sand mixed with the same amount of perlite. 

After cutting and cutting, the cutting ear distance was 6 to 7 cm, the cutting depth was 4 to 6 cm, and the sunshade net with 40% and 50% light transmittance was inserted into the bed, and the cutting ear distance was 6 to 7 cm, and the cutting depth was 4 to 6 cm, and the sunshade net with 40% and 50% transmittance was inserted into the bed. Spray 15-20 ℃ water on the net, spray water every 40-50 minutes on sunny days, spray water every 80-90 minutes on cloudy days, and remove the net when cutting 20 to 25 days, 3 to 4 roots have grown at the base of cuttings and the length of roots is more than 5cm. From the beginning of September to the beginning of September, the bed weeds were pulled out at any time, and it was found that powdery mildew was harmful in August and September, which could be controlled by spraying 1 000 times of 25% Penicillium, and 800 times of 20% acaroid was found to be harmful to red spiders. Water the bed once at the end of October, and then cover the thick and fine broken leaves of 6~10cm to prevent the root and bud from wrinkling and drying in winter and spring. 

Strip seedling. 

Selection of striping mother plant. 

The parent plant with secondary branches on the main stem should be selected for striping, which has strong growth, no diseases and insect pests, and the plant age is more than 3 years old. 

Striping method. 

The effect of horizontal striping is better. From the end of May to the first ten days of June, it is far away from the mother plant 20cm. The deep and wide trench of 5~6cm is opened on the surface of the ground, and the main stem is horizontally introduced into the trench. The upper secondary branch is far away from 1 per 15~20cm, and the length is generally 5 to 20 cm. The length of one main stem is 1 to 1.5m, adding humus soil or fine broken semi-decomposed leaves to the ditch, and finally overlying the original soil and stepping on it. During the growing period, the soil should be kept moist. From the end of October to the beginning of November or April of the following year, 5 to 6 seedlings can be cut out from a 1m long main stem. 

Compared with the above three seedling raising methods, the seedling breeding by sowing method can reach 150000 seedlings per mu and the root system is also developed, while the seedling breeding by cutting method has the advantages of 100 to 120 000 seedlings per mu, but the root system is underdeveloped, time-consuming and high cost. Although there are many roots, the seedling number per mu is only about 10000. Therefore, the seeding method should be used to propagate seedlings, and the cutting and striping method should be used to propagate seedlings as a last resort.
