The mode of reproduction of Schisandra chinensis
Schisandra chinensis is mainly propagated by seeds, and it can also be propagated by means of underground horizontal stem ramet propagation, or asexual propagation methods such as cutting and striping, but in asexual reproduction, in addition to rhizome propagation, it is difficult to rooting and the survival rate is low. the conditions required for treatment are not easy to grasp, and the method of seed propagation is simple and easy to master, and a large number of seedlings can be obtained in a short time. Selection of ⑴ Seeds the seeds of Schisandra chinensis should be selected during autumn harvest, leaving large and uniform ears for seed, drying and managing separately. Dry

Propagation methods of Schisandra chinensis
The method of reproduction. In addition to seed reproduction, wild Schisandra chinensis mainly propagates by walking stems underground. In artificial cultivation, the methods of cutting, striping and seed propagation are often used, but it is difficult to take root and it is not as good as seed propagation. The method of seed propagation is simple and easy, and a large number of seedlings can be obtained in a short time. 1. Seed selection: the seeds of Schisandra chinensis should be selected during autumn harvest, and the ears with large and uniform fruit grains should be left for seed, dried and kept separately. Do not roast, bake or stir-fry when dry. Can be dried or overcast

Harvest, processing and use of Schisandra chinensis
Harvest and processing: a large number of fruits are produced 4-5 years after planting. When the fruit is purplish red from September to October, it is picked with ripening, dried or dried, rubbed to remove the stalk, and the black grains are picked out for storage. Usage: 1. It is used in medicine with ripe fruit: it has the function of tonifying qi and lung, nourishing kidney, astringent essence, promoting fluid, stopping diarrhea and sweat. It mainly treats wheezing cough, spontaneous sweating, spermatorrhea, insomnia, chronic diarrhea, thirst and other diseases. Prescription: (1) neurasthenia, insomnia: Schisandra 15-25k, water decoction. Or use Fructus Schisandrae 50g, break it, use 5

Harvest and processing of Schisandra chinensis
Harvesting was carried out from late August to early October, and harvested along with ripening. It can be dried in the sun or dried at 60 ℃ at room temperature. When Schisandra chinensis is half-dry, lower the temperature to 40-50 ℃. When it is 80% dry, move it outside to the sun to be fully dry. Rub the fruit stalk and pick out the black grains and store them in storage.

Diseases of Schisandra chinensis
The common diseases in Schisandra chinensis cultivation are root rot, leaf blight, powdery mildew and so on. When using pesticides in disease control, the varieties of pesticides registered by the Drug Inspection Institute of the Ministry of Agriculture and allowed by the state must be selected to prevent the adverse effects of pesticides on the growth of Schisandra chinensis and the residual harm of highly toxic pesticides. First, the symptoms of root rot: the disease usually occurs from May to August. At the beginning of the disease, the epidermis at the junction of the root and the ground blackened, further cortical decay, shedding, forming a ring, the leaves wilted, and the whole plant died a few days later. Cause: cause of disease

Causes of herbicide damage of Schisandra chinensis
Chemical herbicides are widely used because of their advantages of low investment, quick effect and labor saving. The types of herbicides are increasing year by year, and the amount of herbicides used is increasing continuously. Although the agricultural department has done a lot of publicity and training on the use of herbicides for farmers, according to the recent investigation of the Beijing Drug Office and Yichun Plant Protection Station, due to the influence of the drift of herbicide droplets, the problem of drug damage to Schisandra chinensis planted nearby is particularly prominent. According to the North Pharmaceutical Office and Taoshan Forestry Bureau of Tieli City, Heilongjiang Province

Control of Common Diseases of Fructus Schisandrae Chinensis
Fruit rot and control of schisandra fruit surface with brown or black spots, later black. Control method: spray 500-600 times solution of 50% ammonium bromide every 10 days for 3-4 times continuously. The root rot of schisandra chinensis and its control mostly occurred from early may to early august. After the disease, the root and surface contact rotted, the root bark fell off, and the plant died a few days later. Control methods: 1:1:100 Bordeaux mixture can be used to irrigate roots. Fruit blight and its prevention and control

Harvesting and seed treatment techniques of Schisandra chinensis
The seeds of Schisandra chinensis have the characteristics of dormancy, the seed coat is hard and smooth, and the oil layer under the skin is not permeable and breathable; the naturally mature seeds have fine embryos and post-ripening characteristics. The longevity of the seeds without pulp is shorter, generally stored dry at room temperature for 2 months, the seed vigor decreases, and the shrunken rate of wild seeds is usually very high. there are two common colors of mature seeds, one is dark red, one is dark red, and the other is orange-red, which is easy to germinate. Schisandra chinensis generally enters the coloring period in late July, and the sugar pigment in the fruit increases with the fruit ripening.

Asexual Propagation and Seedling raising method of Schisandra chinensis-tissue Culture
As a new technology and scientific research means, plant tissue culture has developed vigorously in various fields of plant science, and has been widely used in agriculture, forestry, horticulture, Chinese herbal medicine and other production fields, showing great advantages. A large number of seedlings will be provided in a short time to meet the needs of production. As a means of asexual propagation, tissue culture can propagate 60 000 branches in 8 months with one apple bud, 1 million seedlings in one year with one poplar axillary bud and 500000 seedlings in one year with one Schisandra chinensis bud.

The method of asexual propagation of Schisandra chinensis-hard branch splicing propagation
1-year-old shoots were collected as scions from defoliation to pre-sprouting. 1-2-year-old seedlings were used as rootstocks before freezing and stored at low temperature for cleavage in the sprouting period of the following year (or without local splicing of seedlings). Soak the scion and rootstock in clean water for 12 hours before grafting, and cut off the budding part at the hypocotyls of the rootstock. The scion should choose a fully mature branch with a thickness greater than 0.4 cm, with a cutting length of 4 cm to 5 cm, leaving a bud hole, 1.5 cm on the bud and 3 cm under the bud; use a cutter under both sides of the bud eye of the scion
