It has the functions of astringing lung, nourishing kidney, stopping diarrhea and astringent essence. Mainly produced in Northeast China and Hebei, Shanxi, Shaanxi, Ningxia, Shandong, Hubei and other provinces and autonomous regions.

2, cultivation techniques schisandra mainly with seed reproduction, 8 - 9 months after the fruit harvest, remove the pulp, wash out the seeds. Direct seeding dry seeds do not emerge, because the seed coat is hard, smooth with oil layer, opaque, seed treatment is required before sowing, soaking at room temperature for 2 days and nights, mixing evenly with 3 times the amount of clean river sand, buried in a cooler place, 3 - 4 months later, seed cracks exposed radicle, and then sowing, usually in late autumn or early spring seedling drilling, about 5 kg per mu, covering soil 1.65 cm, watering water, and covering grass, keep the soil moist. After emergence, remove the cover grass, set up shade, and maintain a small amount of sunlight. It can be planted in the early spring of the second or third year. There are two cases, one is the use of natural support, the other is artificial support, selected as a natural support tree species with smaller leaves, growth potential is not too prosperous, hawthorn is an ideal tree species, according to the row spacing of 3 meters *3 meters specifications first planted seedlings, and then planted under each tree 2 schisandra seedlings, 67 cm away from the trunk, one on each side. If artificial support is used, schisandra chinensis seedlings can be planted according to the specifications of large row spacing of 1 meter, small row spacing of 67 cm and plant spacing of 50 cm, and the rows are north-south to facilitate ventilation and light transmission. Schizandra chinensis is a fertile plant. When planting, it is necessary to apply sufficient base fertilizer. First dig holes about 33 cm deep and wide, mix fertilizer and soil into the holes, and make the roots stretch when planting seedlings, which is conducive to survival and growth. After planting, irrigate firmly. Seedling period grows slowly, pay attention to weeding and loosening soil, appropriate watering, the second year after the erection of support for branches climbing, so that ventilation and light transmission, promote growth. In addition to planting when applying sufficient base fertilizer, topdressing every spring, manure or compost 1500 - 2000 kg per mu, calcium superphosphate 15 - 20 kg.

3, harvesting and processing of schisandra fruit after 4 - 5 years of planting a large number of results, autumn 8 - 9 months when the fruit into purple picked, dried or dried.
