How to propagate Eucommia ulmoides? A detailed introduction to the commonly used methods
Eucommia ulmoides, also called gutta-percha wood, has as its main medicinal part its dried bark; this is a very precious tonic medicinal material, rich in minerals and trace and macro elements needed by the human body. So how much do you know about this medicinal material Eucommia ulmoides? Do you know how Eucommia ulmoides is generally propagated? Below are several control methods for Eucommia ulmoides that the editor wants to share with you today, and you can briefly learn about them.
1. Seed propagation
When using seed propagation for Eucommia ulmoides, generally choose fresh, plump, pest- and disease-free, yellow-brown, high-quality seeds. The sowing time mainly depends on temperature, usually when the surface temperature reaches about 10 degrees, that is, in November and December each year and in February and March of spring. Before sowing, the seeds need to be soaked in warm water for about 72 hours, changing the water once every 24 hours, and after the seeds have fully absorbed water, take them out, dry off the moisture, and then sow them at a row spacing of 25 cm.
2. Cutting propagation
Cutting propagation is also a relatively commonly used propagation method, and cuttings are mainly divided into two types, namely stem cuttings and root cuttings. Stem cuttings are generally carried out at the transition between spring and summer, then select vigorous one-year-old branches of Eucommia ulmoides, cut them into small sections of about 5 to 10 cm, treat the cut branches with a rooting agent, and then carry out the cuttings. Root cuttings, however, involve selecting the seedling roots of Eucommia ulmoides, then cutting them into small sections of 10 to 15 cm for cuttings. The survival rate of root cuttings is generally higher than that of stem cuttings.
3. Layering propagation
Layering propagation of Eucommia ulmoides is generally carried out in spring. Select vigorous branches of Eucommia ulmoides and press them into the soil, cover with about 15 cm of soil, then compact the soil, and manage moisture appropriately. In this way, generally after about half a month to one month, Eucommia ulmoides will grow new roots, and then when the individual root system is relatively well developed, separate it, forming a separate plant, and at this point it can be used for planting.
4. Grafting propagation
Grafting propagation may be a bit more complicated. First, we must select the rootstock for grafting Eucommia ulmoides well, and then the scion; for the rootstock, generally choose two-year-old seedlings, and for the scion, generally just choose relatively vigorous branches of Eucommia ulmoides. Then carry out grafting in early spring, and during grafting, disinfect and sterilize to avoid bacterial infection and affect the survival rate of grafting. The most commonly used method for grafting Eucommia ulmoides is the cut grafting method, and the survival rate is also relatively high, reaching more than 95 percent.
By reading the above, everyone should have some understanding of the propagation methods of Eucommia ulmoides, and I hope everyone will be more successful in future planting. Of course, if you have other planting methods, you can also share them with us.
