A planting method of Schisandra chinensis growing in the north

Schisandra chinensis is a woody vine of Magnoliaceae, which is distributed in Northeast and North China, and is mainly produced in Northeast China. Schisandra chinensis is a traditional Chinese medicine commonly used in China, which has the effects of replenishing qi, nourishing the kidney, collecting lungs, astringent essence, promoting fluid, relieving thirst, improving intelligence, calming the mind and so on. It is also a good nervous system stimulant that can enhance the body's defense against non-specific stimuli. It has a good effect on the treatment of neurasthenia, myocardial weakness, edge fatigue, drowsiness, hepatitis and so on.

Schisandra chinensis is not only a rare traditional Chinese medicine resource, but also a unique berry resource, which has a very broad development prospect in beverages, food and health products such as alcohol, fructose, fruit tea, jelly, jam and so on. The bud of early spring is a kind of mountain wild vegetable with high nutritional value, and it can also be processed into Schisandra chinensis tea with health care function. Perennial old vines, commonly known as blood vines and mountain pepper, have the effects of promoting blood circulation, relieving pain, removing wind and dehumidification. Folk drying its vines is still a good seasoning. Schisandra chinensis is a kind of multi-functional and multi-purpose economic plant with high development and utilization value. the products that have been developed include Schisandra alcohol, Schisandrin tablets, liver protection tablets, Schisandra syrup, Schisandra tincture and other health products. The cultivation techniques of Schisandra chinensis are introduced as follows:

1. Selection of cultivation garden of Schisandra chinensis.

The land with good drainage, close to water source and convenient transportation should be selected, and the soil should be loam or sandy loam with good drainage, deep soil layer, good permeability and strong water retention. The garden soil and irrigation water for cultivation of Schisandra chinensis are required to be pollution-free, there should be no seriously polluted factories around, and the atmosphere and irrigation water should conform to China's "Atmospheric Environmental quality Standard" and "farmland Irrigation Water quality Standard". It is suggested that the plots with the application of sulfuron-methyl pesticides and pesticides with long residual period should be planted after the pesticide failure period so as to avoid drug damage and affect the survival rate of Schisandra chinensis planting.

Digging planting ditches

To dig planting ditches in the selected garden, the flat land should be oriented north-south, so that the plants can receive uniform sunlight; the slope should be determined according to the topography [www.cyonE.com.cn/], and the planting row orientation should be parallel to the contour line. The planting row spacing is 150 cm, the plant spacing is 40-50 cm, the planting ditch is 60 cm wide and 30 cm deep, and the topsoil and inner soil are put aside. Fertilizer collocation: about 3000 kg of rotten farm manure (pig, chicken, human feces and urine, etc.) and 25 kg of diammonium phosphate are applied to every 667m2 (1 mu). Soil and fertilizer backfill: first fill a layer of topsoil in the ditch, then fill half of the fertilizer into the ditch, then cover a layer of soil, mix the other half of the fertilizer into the upper soil, the backfill should be 10 cm higher than the ground. Only topsoil can be filled in the ditch, not core soil. The trenches should be dug, broken and raked flat at least a week before planting.

III. Prevention and control of diseases, insect pests and weeds in the garden

1. Garden disinfection: in order to better ensure the healthy growth of Schisandra chinensis, we should first disinfect the soil of the garden, which can be disinfected by the following methods:

(1) ferrous sulfate disinfection. Treat the soil with 3% ferrous sulfate solution, 0.5 kg per square meter. After the ferrous sulfate is diluted into a 3% concentration solution with clean water, the surface layer of the soil is sprayed with a sprayer, or directly irrigated into the soil.

(2) carbendazim disinfection. Carbendazim can control a variety of fungal diseases, and has a good control effect on diseases caused by cystic bacteria and half-known bacteria. 50% wettable powder can be used for soil disinfection, 1.5 grams per square meter.

(3) Dysenamine disinfection. Dysenamine has strong bactericidal power, can infiltrate into the plant, and has a certain fertilizer effect after decomposition in the plant. It is generally sprayed with a 350-fold solution of 50% Dysenamine.

two。 Early prevention of weeds in the garden: the specific method is: after disinfecting the garden soil, use Guoer (24% EC), when the weeds have not sprouted, use 50 ml of medicine every 667 square meters with 60 kg of water to seal the soil evenly. During the application, the soil in the field should be kept moist to facilitate the complete formation of the film.

4. Preparation and planting of Schisandra chinensis seedlings

The 1 ~ 2-year-old Schisandra chinensis seedlings with strong growth, complete root system and no disease were selected and planted in spring or autumn. Take spring planting as an example: leave a height of 5 cm from the root upward, cut short, retain 2 full-growing buds, and then plant according to the plant spacing of 40 cm to 50 cm. After planting, gently lift the seedling and fill the soil, pour enough water after it is firm, and cover the soil 1 cm to 2 cm after sinking under water.

5. Plastic film mulching

After planting a row of seedlings, cover the plastic film while breaking the film to release the seedlings. When releasing seedlings, use a knife or stick to cut a small hole in the mulch on the seedling to introduce the film, and then cover the mouth of the film. After releasing the seedlings, seal the pores in the roots of the seedlings with fine wet soil at any time to maintain the temperature and moisture under the film. When spreading the leaves of the seedlings, pour the seedling protection water again, the method is: each seedling is irrigated with 0.51kg water (depending on soil moisture), once frozen water after planting in autumn, and can be carried out according to the requirements of spring planting in the next spring.

VI. Setting up a fight

Schisandra chinensis should be set up in time for its attachment after transplanting. The frame materials can be adapted to local conditions. It is better to have a single-sided frame. Let's take the scaffolding as an example to introduce the construction of the scaffolding: first, a 2.5-meter-long wooden pile is used as a column, and a column is set up every 5 to 8 meters along the bed, which is buried in the ground about 50 centimeters, and then the No. 8 or 10 wire is used to pass through the post 1.5 meters and 2.0 meters above the ground. after being tightened with a wire tensioner, it is tightly wound around the posts at both ends. Then use nylon thin thread or old wool (if possible, it is best to use bamboo pole or frame) to fix one end on the ground of the root of the seedling, and tie the other end to the iron wire, and use it to lead the branch to the frame when the seedling enters the height. Each seedling should be provided with two leads (rods), one vine and one thread (rod). The distance between the vines is about 20 centimeters. The following spring, after pulling an iron wire in the column between the rows, and then pulling two iron wires in the direction of the row to form a scaffolding for the branches to cling to. This type of frame is beneficial to the ventilation and light transmission of the plant.
