Techniques of transplanting and protecting seedlings of Schisandra chinensis
In recent years, the demand for Schisandra chinensis has increased, and the price has risen. Many farmers have tried artificial cultivation, but the survival rate is not ideal, which not only affects the enthusiasm of farmers, but also wastes a lot of manpower, material and financial resources. This paper introduces a set of transplanting seedling protection technology, which can be used as a reference for farmers.
First of all, land preparation.
Choose land that is fertile, overcast and does not accumulate water. Change the traditional pit planting into trench planting. Because the root penetration of Schisandra chinensis is poor, the adventitious root absorbs water and nutrients, so it is necessary to activate the soil layer and imitate its original ecological growth conditions. According to the line spacing of 1.5 meters, dig a ditch 50 cm wide and 40 cm deep.
The excavated soil is placed separately according to the surface soil and the core soil. First spread a layer of straw at the bottom of the ditch, which is not only organic fertilizer but also waterlogging and drainage, (5 cm is appropriate). Then a layer of farm manure and a layer of core soil are backfilled, and then biological fertilizer, farm manure and topsoil are backfilled, which should be more than 20 centimeters above the surface to prevent subsidence and depression. After the backfill is settled, it can be transplanted.
The second is transplanting.
It is better in October in autumn, and it can also be transplanted in March-April in spring. In order to obtain high yield in the early stage, about 900 seedlings are needed per mu. It is better to have two-year-old seedlings. The suitable distance between plants is 50 cm. After winning the early high yield, the vines are more developed, and then press 1 meter away from the plant to remove the excess. To prevent the nest root when transplanting, cover the soil and bury it to the neck of the seedling root. After stepping on the ridge and pouring water, it should be covered with 5 centimeters of fallen leaves or straw. Heat preservation, moisturizing and activating the soil layer, at the same time, it can also save the trouble of frequent watering and loosening the soil, and has a certain suppressing effect on weeds. The covering measure is the key to improve the survival rate and yield of Schisandra chinensis.

Seedling raising technique of Schisandra chinensis
As a traditional Chinese medicine, Schisandra chinensis is the top grade of Schisandra chinensis, which mainly grows in the eastern mountainous area of Liaoning Province. The price of Schisandra chinensis has gone up in the market in recent years, and the supply exceeds the demand. The main reasons are: first, with China's accession to the wto, the export volume of traditional Chinese medicine increases, and the market demand for Schisandra chinensis increases; second, with the development of animal husbandry, Wuwei wild resources are destroyed, especially, goats like to eat Wuwei. In the past two years, Schisandra chinensis has been cultivated artificially in Liaoyang, Dandong and other areas, but because the seedling technology is not mature, many farmers do not produce seedlings or come out.

Schisandra chinensis changed from wild to home.
Nowadays, the wild resources of Schisandra chinensis are decreasing day by day, and the market demand is increasing. The research of Schisandra chinensis from wild to home planting has been successful and achieved high economic benefits. First, garden site selection and planting 1. Garden site selection. Schisandra chinensis is suitable for slightly acidic soil, and can be cultivated in large areas where the annual frost-free period is more than 115days and the accumulated temperature is more than 2300 ℃. The garden should choose flat land or shady sloping land with good drainage and low groundwater level. The hedgerow was planted with a row spacing of 0.75 m × 2 m. 2. Preparation work before planting. Enter the winter
