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.

I. Garden site selection and planting

1. Garden choice. 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. Dig the hole 50 cm deep according to the definite row spacing before the beginning of winter. 3. A certain plant of seedlings. It was planted in late April. Soak the seedlings in clean water for 12-24 hours before planting and cut off moldy, damaged and overgrown roots (15cm and 20cm). After planting, a soil-water plate with a diameter of 50 cm to 60 cm was made around the stem of the seedling, and the soil was covered with water.

II. Field management

1. Ploughing and weeding. Ploughing and weeding more than 5 times a year, with a depth of 10 cm, keep the soil loose and free of weeds. 2. deep ploughing. After the fruit was harvested, the whole garden was ploughed deeply, with a depth of 20cm and 25cm, ending in late September. 3. Intercropping and removing root tillers. Remove the sprouting tillers from the base of Schisandra chinensis before sprouting. 4. Topdressing. Topdressing twice a year. For the first time, ammonium nitrate was applied before sprouting. The second time in the fruit coloring period, calcium superphosphate and potassium sulfate were applied. The amount of fertilizer is increasing year by year. Ammonium nitrate 25g / plant, calcium superphosphate 200g / plant, potassium sulfate 10g / plant.

Third, overall pruning

1. Stand pole. The branches of Schisandra chinensis are soft and cannot stand upright. Bamboo poles (or wooden poles) can be inserted on both sides of the plant to induce it to grow upward. 2 or 3 fixed main vines can be retained on each bamboo pole. 2. Summer shelf management. When the plant is young, the selected main vine should be entangled on the bamboo pole in time. The new shoots of adult trees with lateral vines need not be bound, and if they are too long, they can be left with about 10 knots to pick the heart. The side vine must be tied up so as not to break. 3. Winter pruning. ⑴ pruning period. It can be cut in winter from 2 to 3 weeks after falling leaves to before bleeding in the following year. ⑵ pruning method. The cut is 2 × 2.5 cm away from the bud. The plant is 30 cm from the ground, leaving no lateral branches. When the branches are not covered with shelf surface, cut off the immature part of the extended branches, leave 6-8 buds in the lateral vines, 1520 cm apart, 10-15 medium-long branches per plant, and the leaf clumps are not cut. The medium-long branches left by last year's pruning should be retracted in time, leaving only one leaf clump branch and medium-long branch in the stem. Find a branch that can replace it in the lower part of the extended branch of the previous year for renewal. When the lower part of the main vine is bald due to the senescence or the upward movement of the fruiting part, the strong sprouting tillers from the stem of the plant should be selected and cultivated into a new main vine.

IV. Pest control

1. Powdery mildew and black spot. The onset period of the two diseases is similar and can be controlled at the same time. Spray the same amount of Bordeaux solution 100 times in late May to prevent, if there is no disease, spray again every 7 to 10 days. If the disease occurs, the powder and mancozeb are prepared into 800x liquid spray by 1:1 method. 2. Strengthen management. The branches should be evenly distributed on the shelf surface, ventilated and transparent. Before sprouting, clean up the diseased branches and leaves in the Schisandra orchard, bury them deeply or burn them, and spray the stone sulfur mixture of 5 Baume degrees in the whole garden once.
