? 1, line direction
Schisandra chinensis has the best cultivation direction, good lighting and ventilation, which lays the foundation for stable and high yield.
? 2. Dry
The seedlings of Schisandra chinensis grew vigorously in the summer of transplanting. Choose 3-4 robust lateral branches for each plant to lead the vines to the poles. 1 The seedlings have 2 poles, each pole climbs 2 main vines, and the main stems of the original seedlings are cut off. When the main branch of each vine grows to 50cm long, top it and dry it, so as to promote the branches under the incision to grow young branches (that is, short fruit branches, also called secondary branches). When the new shoot grows to 30 cm, 1 strong seedling is selected as the main extension branch, and other secondary branches point to 20 cm. In that year, only the secondary branches were pointed, and the extended branches were not pointed to beginning of autumn.
? 3. Scaffolding
Polygonum multiflorum is monoecious, and the number of female flowers is the key to yield. In cultivation management, improving the ventilation and light transmission conditions of the frame surface by pruning can improve the photosynthetic efficiency of leaves, increase the number of female flowers and ensure stable and high yield. Pruning lays a good skeleton for stable and high yield. Before the sap flows out in early spring, the main branches that were extended last year should be cut off by 30 cm and the auxiliary branches should be shrunk to 20 cm. If there are no auxiliary branches, cut off the protruding main branches 50 cm from the ground and dry them. When the length of each new secondary branch under the cutting is 20cm, 1 secondary branch is selected as the extension branch, and the others all reach the peak at 20cm, so as to promote the main vine branches to be strong and the flower buds on the secondary branches to be full. When the length of the main vine branch is extended to 50cm (including the original 30cm), acupuncture should be carried out again, and the remaining auxiliary branches should be acupuncture 30cm to concentrate nutrition on the main vine branch and each auxiliary branch, which can increase the number of female flowers and make the flower buds fully mature and full. Before and after the third trip to beginning of autumn, we should sharpen the tips to lignify the branches as soon as possible to prevent freezing injury.
In addition, the main vines should not be intertwined, and the secondary vines will always be secondary vines. Don't turn to the main vine, this situation should be corrected in time.
? 4, periodic update
When a large number of fruits are produced, all secondary branches (short fruit branches) shrink to 10~ 15cm before the juice flows out in early spring. When flowering and fruiting, new short fruit branches can be sent out at the intersection of the base and the main vine branches, and the healthy parts are selected as the fruiting branches in the next year, and the rest are removed in time to prevent competition with the mother branches for nutrients. When pruning next year, cut off the old fruiting branches and recycle the new ones. This pruning method will basically be used in the future. In addition, when the main vine branches climb over the pole that is not high enough, the branches will fall, so they should be cut off at the top of the pole 10cm in time to prevent "wearing a straw hat" from being harmful to light transmission.
? 5, spring, summer and autumn scissors
Pruning of Schisandra chinensis can be carried out in spring, summer and autumn, and timely pruning in summer is the key to the three seasons. If you don't prune in summer, the branches on the shelf will compete to grow, and the number will be numerous and messy, intertwined and too lush, which will not only fail to stabilize and produce high yield, but even make the flowers fruitless, which is not conducive to flowering and pollination, and the yield will decrease year by year.
5. 1 spring scissors. Generally, it is carried out before the branches germinate, and the dense and dead branches are cut off. After cutting, the branches are moderately dense and do not interfere with each other.
5.2 summer scissors. Generally, it is carried out from early May to early August, and the basic branches, drilling branches, overlapping branches, pest branches and so on are mainly cut off. At the same time, too dense new branches also need to be thinned or shortened. Summer cutting is going well, and you can cut it lightly or not in autumn.
5.3 autumn scissors. After defoliation, the basic branches after summer pruning are mainly cut off.
Whenever pruning, you should choose to leave 2~3 vegetative branches as the main branches and lead the vines to the shelves.
