How to propagate Michelia alba? Detailed introduction to propagation methods
Michelia alba is a common flowering potted plant, and it has a relatively large market in China. Moreover, Michelia alba has a very wide range of uses. It not only has ornamental value, but is also widely used in various industries such as fragrances and building materials. Therefore, with demand, its planting area is continuously expanding, and the yield requirements are also getting higher and higher. So if you want to expand the cultivation area, how should you propagate Michelia alba? Let's take a look together with the editor below!
1. Grafting propagation
Grafting propagation is one of the most commonly used propagation methods for Michelia alba. First, choose a magnolia of about 5 mm as the rootstock, then do a good job in cultivating the rootstock to improve the grafting survival rate. Then select a branch about one year old from the mother plant as the scion. Next, make a slanted cut on the rootstock for the graft union, ensuring the cut is smooth enough. Then cut an incision on the scion that is the same size as that on the rootstock, align them, and wrap them well with grafting film to prevent water seepage from affecting the healing of the union. Then do a good job in management, keeping the soil moist and preventing direct sunlight.
2. Layering propagation
Layering propagation should be carried out before the start of the dog days. First, choose a tender branch that develops normally, has no wounds, and is free of pests and diseases, and keep its length at about 1.8 cm. Then dig a small trench at the base of the plant, perform girdling on the branch, and be careful not to damage the xylem. Then apply an appropriate amount of rooting agent to the girdled area to promote rooting. Then cover the girdled area tightly with wet soil, wrap a layer of plastic film on the outside, and tie it tightly. The main thing is to ensure the soil is moist enough. Under normal management, rooting generally occurs around May of the following year.
3. Seed propagation
Michelia alba can also be propagated by seed propagation. Harvest the seeds after they mature each year. When the seeds are found to gradually crack and turn red, it means the seeds are gradually maturing. Then store the seeds in sand and sow them in the spring of the following year. When sowing, pay attention to doing a good job in disinfection and germination promotion to improve the seed germination rate and survival rate. After sowing, germination begins in about 4 weeks, but if the germination time is longer, it may take about two months. When the seedlings grow to about 10 cm and have 5 true leaves, transplant them. The transplanting time should be chosen in the evening when the temperature is suitable.
The above is a brief introduction to the propagation methods of Michelia alba. Michelia alba is not suitable for cutting propagation because the survival rate of Michelia alba cuttings is very low. We should reasonably choose propagation methods according to our own conditions, cultivation environment, and other actual circumstances. That is all for today's introduction.
