High-yield Cultivation Techniques of Fructus Schisandrae Chinensis

Schisandra chinensis is a medicinal plant. Its wild resources are decreasing and the market demand is increasing. The key points of high-yield cultivation techniques of Schisandra chinensis are as follows:

1. Schisandra chinensis is suitable for growing in slightly acidic soil, the frost-free period is more than 115days per year, and the area with accumulated temperature above 2300 ℃ can be cultivated in a large area. The cultivated garden should choose flat land or shady sloping land with good drainage and low groundwater level. Planted with hedgerow, the row spacing is 0.75 m x 2 m-1.0 m x 2 m. 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-20cm). After planting, water thoroughly and cover the soil.

two。 Field management ploughed more than 5 times a year to keep the soil loose and free of weeds. After the fruit was harvested, the whole garden was ploughed deeply, with a depth of 20 cm-25 cm. Before the sprouting of Schisandra chinensis, the sprouts produced at the base of Schisandra chinensis were cleared and ammonium nitrate was applied. During the fruit coloring period, calcium superphosphate and potassium sulfate were applied. Generally, each plant is given 25 grams-100 grams of ammonium nitrate, 200 grams-400 grams of calcium superphosphate and 10 grams-25 grams of potassium sulfate.

3. Plastic pruning plants should guide the selected main vines to the bamboo pole in time when they are young. The new shoots of adult trees with lateral vines need not be bound, and those that are too long can be left with about 10 knots to pick the heart. The side vine must be tied up so as not to break. Winter pruning is carried out from 2-3 weeks after deciduous leaves to before "bleeding" in the following year, and the cut is 2-2.5 cm away from the bud. No lateral branches are left below 30 cm from the ground. When the branches are not covered with leaves, cut off the immature parts of the extended branches, leaving 6-8 buds on the lateral vines, 15 cm-20 cm apart, 10-15 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. In the previous year's extension of the lower part of the branch to find a replacement for its branches for renewal. When a main vine is senescent or the fruiting part is moved up, the robust sprouting from the stem of the plant should be selected and cultured into a new main vine.

4. In late May, Bordeaux solution (100 times liquid) was sprayed for pest control. If no disease occurs, it should be sprayed again every 7 to 10 days. If the disease occurs, the powder and mancozeb can be mixed into 800 times liquid spray, the effect is better. Pay attention to the uniform distribution of branches and vines on the shelf surface to maintain ventilation and light. Before sprouting, clean up the diseased branches and leaves in Schisandra chinensis orchard, bury or burn them deeply, and spray the stone-sulfur mixture with Baume degree of 5 degrees in the whole garden.
