What are the latest propagation methods for Kadsura coccinea?
Kadsura coccinea is a new type of fruit that has become popular in recent years. Although its planting area in China is not large, it has a certain market demand. At present, China's Kadsura coccinea market is still in a state of supply falling short of demand, so more and more people are starting to grow Kadsura coccinea. So when we grow Kadsura coccinea, how should we propagate it? Below, the editor brings you the propagation methods for Kadsura coccinea. Let's take a look!
1. Seed propagation
Seed propagation refers to sowing and propagation. Seedlings grown from seed have strong root capacity and fast growth, but the possibility of variation is also relatively high, and quality cannot be guaranteed. After harvesting the seeds, put them in wet sand for heaping and storage to prevent water evaporation from reducing the germination rate. Then sow in spring. Before sowing, apply sufficient base fertilizer to the soil, make beds and shape them, and control the plant and row spacing to open furrows and dig holes for sowing. Place about two seeds in each sowing hole. After sowing, cover with fine soil, then cover with plastic film to improve the soil's moisture-retention capacity. After seedlings emerge, remove the plastic film in time. After three true leaves grow, thin the seedlings once, and when five true leaves appear, finalize the seedlings. Do one intertillage and weeding operation, and topdress about once a month.
2. Cutting propagation
In spring each year, cut off vigorous, pest- and disease-free one-year-old branches, cut them into cuttings about 12 cm long. Each cutting should have about 4 buds, keep one leaf at the top, and cut off excess leaves. Then cut the insertion end into a slanted cut; the larger the wound area, the greater the rooting rate. The cut must be kept smooth, then soak the cut in rooting agent for about half an hour to improve the rooting rate. The seedbed preparation work is the same as for seed propagation. Insert the cuttings obliquely into the seedbed, keep the lateral buds moist, then press the soil firmly and water thoroughly to increase the contact area between the cuttings and the soil. During the rooting period, do a good job of weeding. After rooting, topdress appropriately, mainly with frequent small amounts, to prevent excessive amounts from causing the cuttings to die.
3. Grafting propagation
Grafting propagation is the most commonly used propagation method for Kadsura coccinea, and there are many grafting methods. Taking bud grafting as an example, at a place about 8 cm above the ground on the rootstock, cut a wound about 3 cm long, then cut open half of the outer skin of the cut. Cut the bud upward from the bottom into a bud piece, with the length controlled at about 2.5 cm. Then insert the leaf into the cut, tie it tightly, and after clamping it with a grafting clip, expose the leaf bud. After about a week, if the bud piece is fresh and the petiole falls off loosely, it means it has survived. If it has not survived, then supplement the graft in time. After about 2-3 weeks, remove part of the leaves and vines to promote the growth of the grafted bud.
The above is a brief introduction to how Kadsura coccinea is propagated. Each propagation method has different advantages and disadvantages. Cutting propagation has a high survival rate, but its root capacity is weak and its growth is poor, so it should be planted appropriately densely. Although grafting propagation combines the advantages of seed propagation and cutting propagation, it is rather troublesome to operate. Therefore, everyone should reasonably choose a propagation method according to their own propagation techniques and planting direction.
