Schisandra chinensis is a magnoliaceae plant, its dry and ripe fruit has high medicinal value, and has the functions of astringency, nourishing, Shengjin and antidiarrheal. With the destruction of natural resources and artificial over-collection, the Chinese medicine market is currently in short supply, artificial cultivation. The prospect is vast. This is a Chinese herbal medicine project with a large investment, a long period, and a considerable income. Therefore, cultivation technology is particularly important.

First, choose the site preparation. The nursery should choose land that is loose and fertile, near water source and well-drained. The old ginseng land is best. After ploughing and cultivating, 15-15 cm in height and 15-15 cm in depth are produced in a height of 15 cm and a width of 120-150 cm. In addition to fertility, good drainage and irrigation, the planting site requires a slope of less than 15 degrees, digging at a distance of 0.8-1.1 meters, and using semi-artificial cultivation to select a plant with a scaffold.

Second, nursery transplanting. At present, Schisandra is mainly seed-breeding, supplemented by ramets and cuttings.

1. Seed nursery: Seeds harvested in the current year are soaked in warm water for 2-3 days before sowing. The pulp is washed away and the seeds washed out. After being mixed with 3 times the wet sand, the seeds are placed on the outdoor natural stratification treatment. After thawing in the spring of the following year, they are moved into the room and continue to stratify. After most embryos are mature and mature, they can be sown (about the middle of May). According to the line spacing 15 cm trenching, soil covering about 2 cm, a slight repression after the cover grass moisturizing, Mu sowing amount of about 5 kg. After 3-4 weeks of emergence, the cover grass is removed and a shed is erected (removed in late August). The seedling stage is combined with loose soil and weeding for seedling thinning. When the young shoots reach 3-4 leaves, the seedlings are planted at 5-7 cm spacing. , when 5-10 leaves can be transplanted and colonized.

2. Cutting seedlings: Before sprouting in early spring, cut two-year-old shoots to make cuttings. The cuttings are cut to 15 cm in length, each with 2-3 nodes, and then inserted into the seedbed at a spacing of 157-10 cm at 27-31°C. Under conditions, promote rooting. It is also possible to cut twigs in July, cut into 10 cm long shoots, insert 157-10 cm rows of planters, pay attention to moisturizing and shading, and transplant in the fall of the second year.

3, transplanting: Spring and Autumn can be carried out. All during the dormant period. According to the spacing of 70-90 cm 100-120 cm digging points, hole depth 30-35 cm, diameter 60 cm, 2-3 kg each time to apply decayed ring fertilizer, mixed with soil after planting seedlings, when planting to make the root stretch After the practical, pouring water.

Third, field management

1. Stretching: After transplanting and planting, it should be erected for climbing. The stents are divided into natural stents and artificial stents. The trees of the natural stents should have appropriate heights and sparse crowns. The red or mountain sticks are better. The artificial stents are erected with cement columns and a column is set every 4-6 meters. A galvanized iron wire is pulled at a height of 50 cm and the schisandra vine is tied to the iron wire.

2, weeding, top dressing, irrigation: after transplanting, weeding according to field conditions, 4-5 times a year, cultivating depth of about 10 cm, to achieve a good loose soil permeability, and play a role in drought and water conservation, in the weeding process, do not hurt root. Top dressing twice a year, for the first time before the opening of buds in the middle and late May, can increase the fruit setting rate, 25 grams per thiamine, superphosphate can be used; the second time, in the middle and early July, Calcium phosphate 50 grams per plant to facilitate flower bud differentiation. The schisandra flowering season is in the dry season and it should be flooded to prevent falling and fruiting. The soil should be kept moist during fruit enlargement. Before the freezing season, the roots should be filled with water and then the soil should be cultivated in order to facilitate the winter and the following year.

3, pruning: Schisandra is a dry multi-branch plant, in order to continue high yield, in maintaining adequate fertilizer, water, ventilation, light transmission, but also must be completed through pruning. Pruning is mainly done in winter and spring. When trimming, cut out 2-2.5 cm from bud eyes, 30 cm from the ground, and leave no side branches on the plane. Add 2-3 main vines attached to bamboo raft on the ground, and all other parasitic branches. Cut off, when the vines are not covered with shelves, only the immature part of the main vine extensions can be cut off. The pruning of the lateral vines is mainly medium and long shoots, and the spacing is maintained at 15-20 cm. It is better to have about 13 long branches per pole, and the confederate branches do not cut in principle. When the main vines age, they should be selected from the plant basis to keep strong twigs as new vines to prepare for renewal. Cut off parasitic branches, branches, lateral branches, diseased branches, and newly emerged branches. Reasonable pruning can improve structure, rejuvenate plants, and prolong result age.

4, disease prevention and pest control: The disease mainly has blight, root rot, powdery mildew, black spot, etc., insect pests mainly leaf curl insects, borer, red spider and so on. Pest control must adopt pollution-free prevention and control methods to prevent the medicinal value of schisandra. The basic principles for using pesticides are: (1) to ban highly toxic, highly toxic, and high-residue pesticides; (2) to rationally use pesticides; (3) to alternate use of drugs to reduce pests The drug resistance; (4) master the amount of drug and spray time, to avoid the occurrence of phytotoxicity; (5) improve the utilization of pesticides, the right medicine; (6) continuous use of pesticides interval of 7-15 days. The production field of schisandra must prevent the invasion of 2,4-D butyl ester.

Fourth, harvest. When the fruit is bright red during September-October, pick it up, cut it, and put it in the sun and dry it. When it's sunny and night, let it be moist with dew, so that the schisandra oil is of good quality. When the handcuffs are elastic, it's good to loosen and recover. Its handle, impurities can be stored or sold.
