Schisandra chinensis (Turcz) Baill.Hist.) is distributed in the northeast of China as a wild woody vine fruit tree. The fruit is not only a commonly used rare Chinese medicinal material in China, but also a raw material for processing fruit wine and fruit juice beverage. Due to the destruction of human factors such as long-term predatory picking, wild resources are scarce. While strengthening the protection of resources, large-scale artificial cultivation is the fundamental way to solve the shortage of raw materials. According to years of research results and production experience, provide practical cultivation technology of the North Schisandra for reference only. 8, the application of new results (1) Schisandra Huang Ye Ling This product is a powder, specifically for the treatment of Schisandra yellow leaf disease, white leaf disease, 7-10 days effective.
Size
Because of different growing environment and conditions of itself, the fruit will be different types of shapes and sizes, usually we deliver the size 220/280/320/350 and so on, but can also supply other sizes.

1. Selection of land: Choose a well-drained flatland with a groundwater level of 1 meter or less.
2, planting: cultivated varieties should be selected high-quality seedlings, it is best to adjust the seedlings than the cold nursery base in this area, set the spacing of the plants in line with local conditions, when planting a little biological special fertilizer.
3. Soil management: Weeding and weeding were repeated several times in a year, and weeds were kept loose and weed free. After the fruit is harvested, the whole garden will be deep-cultivated and the depth will be 20-25cm; the sprouting of the plant will be timely removed from the base of the plant. Watering was performed before and during the berry growing period.
4, fertilization: According to the fertility of the earth and Schisandra growth appropriate timely.
5, pruning
5.1 The schisandra twigs of the stand bar are not soft and can not stand upright. They need to be wrapped up with sticks to grow upwards. Therefore, it is necessary to artificially set up the poles and combine pruning to complete them.
5.2 Winter pruning Winter pruning may be performed from 2-3 weeks after the plants fall to the beginning of the injury in the following year, but it is advisable to finish in mid-to-late March. When pruning, cut 2~2.5cm from the eye, leaving no side branches within 30cm from the surface. When the branches are not covered, only the immature part of the main extension branch is trimmed; the trimming of the side branch is dominated by the middle long shoots (leaving 6-8 buds), the spacing is maintained at 15-20 cm, and the individual plants are cut. 10-15 leaves are suitable for the middle and long branches, and the leaf twigs are not cut in principle. In order to promote the germination of the basal buds, the short shoots and the ultra short shoots can be trimmed by cultivating the preparation branches (leaving 1-3 shoots). ). The middle and long branches that were cut off from the previous year must be promptly retracted. Only one leaf branch or middle branch should be kept at the base. Therefore, the pruning should be performed in the important part of the lower part, and most of the nodes on the branch should also form leaf branches. The extension branch of the previous year is also an important part of the result, and most of the nodes on the branch are also susceptible to the formation of leafy branches. Therefore, the pruning branches must be replaced with replaceable branches in the lower part of the tree. When one of the main vines is found to be senescent or parts of the vine are moved upward and the lower part of the body is bare, they should choose to leave the strong scent that is sent from the base of the plant as the new main vine and remove the old vine. When the plants enter adulthood, they often have large, well-developed basal buds at the intersection of the main lateral branches. Most of these shoots are able to extract very strong shoots. This creates good conditions for renewal of lateral branches and should be used with caution. .
5.3 summer shelf management plants in the young age to select the remaining main vines lead to the bamboo rod to promote its upward growth, mature tree side vines in the new students do not need to tie in principle, if there is too long It can leave around 10 knots to pick up the heart. The side vines (results of the mother branch) are left with too long or heavy loads. The necessary binding should be given to avoid breaking the branches.
6. Pest and disease control Powdery mildew and black spot are two common diseases of the schisandra chinensis. They usually occur in early June. The pests that harm North Schizandra are mainly fruitworms, foam bombs, adult beetles, and caterpillars. Most of the hazard period is from late May to late August. The prevention and control methods are as follows.
The origins of the two diseases were similar, and they were sprayed once in late May. The 1:1:100-fold equivalent Bordeaux mixture was used for prevention. If no disease occurred, it could be sprayed once every 7-10 days.
0.3-0.5 degrees lime sulfur or triadimefon, thiophanate-methyl wettable powder 800 times; black spot use mancozeb 50% WP 600-800 times liquid control. If both diseases are developing, triadimefon and mancozeb may be mixed and formulated for one-time control, and the concentration may still be used at the respective concentrations used above.
In management, pay attention to the reasonable distribution of shoots, increase the proportion of phosphorus and potassium fertilizers to increase the disease resistance of the plants; before cleaning, the branches and leaves of the disease are burned or buried deeply. The whole park sprays 1 degree 5 lime sulfur.
7. Fruit-creating and frost-resisting Schisandra chinensis in Heilongjiang and Jilin provinces are vulnerable to late-night frost damage, and even result in the end of the year. Two-year application of fruit-increasing anti-frost agents can not only resist late frost invasion, but also increase fruit yield by 10-40. %. system
(2) Biological special fertilizer According to the growth characteristics of Schisandra chinensis, the bio-fertilizer uses chicken manure with high nutrient content as base material, adds plant micropowder, various trace elements, and acid adjuster, etc., and utilizes more than 80 kinds of microbial flora. A special fertilizer made from biological agents that can be quickly absorbed and utilized by schisandra plants, especially as an oral fertilizer, has a long effective period, and is safe and efficient.
