Artificial Cultivation Techniques of Schizandra chinensis

Schisandra chinensis, also known as noodle vine, mountain pepper, belongs to Magnoliaceae, winding vines. The stem can be up to 8 to 10 meters long, reddish brown. Simple leaves alternate, broadly ovoid, petiole often reddish. Flowers unisexual, dioecious or monoecious. Aggregate berries globose, red, clustered on elongated pedicel rachis. The flowering period is from May to June and the fruit ripening period is from August to September. Born in woods on sunny slopes, twining around other plants. Schisandra chinensis generally begins to blossom in the third year, but the number of flowers is small and rarely bear fruit. After growing for 4-5 years, the fruit can be harvested, the yield per mu is more than 400 kg, and its yield is increasing year by year. Its medicinal part is fruit, warm in nature, entering the two meridians of lung and kidney, and has the effect of nourishing kidney and lung, promoting fluid and collecting sweat, astringent essence and calming the nerves. Mainly produces Liaoning, Jilin, Heilongjiang, Hebei and other places. The inherent quality and efficacy of Schisandra chinensis is better than that of Schisandra chinensis, and its market prospect is promising, so it is the first choice for rural areas to adjust the planting structure and farmers to get rich.

The cultivation technique of Schisandra chinensis is suitable for cool and cold climate and should be planted in rich and deep humus soil. Before sowing, 3500-5000 kg of barnyard manure per mu was applied as base fertilizer, and then the soil was ploughed 20-25 cm deep, making a seedbed 1.5 meters wide. There are two planting methods: seed method and cutting method. The seed method is to soak the seeds in water for 3 days, rub off the pulp, and then rinse off the pericarp and inferior seeds with clean water. Spring sowing is from late March to early April, and autumn sowing is from early September to early October. When sowing, it is appropriate to sow 1520 grains per square centimeter, cover the soil with 2cm, cover with straw, water and moist. When strip sowing, first trench the border with a distance of 25cm to 30cm, then sow the seeds into the trench, cover the soil by 1.5cm, cover the soil with straw and water it. When planting with the cutting method, 2-3-year-old branches can be selected from June to August, cut into sections of 12cm to 15cm, inserted directly in the seedbed, and often watered to keep the soil moist, which can promote rooting.

In the growing period of field management seedlings, scaffolding should be set up to shade, weed and loosen the soil in time, and after 2-3 years, it can be transplanted into the field according to the standard of plant spacing of 30 cm and row spacing of 50 cm. If the disease is found, it can be sprayed with lime water and Bordeaux solution. In addition, every two rows of Schisandra chinensis plants should be built with bamboo poles or wooden poles, the bottom should be buried firmly, the upper part of the frame pole should be tied up with iron wire, and the passage should be connected with iron wire, so that the Schisandra chinensis plants can climb and grow on the frame pole.

The harvest period is from September to October, but the harvest in October is the best. After the fruit is picked, the impurities such as fruit stalks are removed and dried directly. You can also use the quick-drying method. The Schisandra chinensis to be picked will be dried for 2-3 days, then boiled in a boiling water pot, and then dried for 4-5 days.
