What are the latest propagation methods for Eucommia ulmoides?
Eucommia ulmoides, also called the gutta-percha tree, has as its main medicinal part its dried bark; it is a very precious tonic medicinal herb, rich in minerals and trace and macro elements needed by the human body. So how much do you know about this medicinal herb 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; you can take a brief look.
1. Seed propagation
When Eucommia ulmoides is propagated by seed, generally choose fresh, plump, pest- and disease-free, yellow-brown seeds of excellent quality. The sowing time is mainly related to temperature, usually when the surface temperature reaches about ten 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; after the seeds have fully absorbed water, take them out, drain the water, 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: branch cuttings and root cuttings. Branch cuttings are generally carried out at the turn of spring and summer; then select robust 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 insert them for cutting. Root cuttings, however, involve selecting the seedling roots of Eucommia ulmoides and then cutting them into small sections of 10 to 15 cm for cutting. The survival rate of root cuttings is generally higher than that of branch cuttings.
3. Layering propagation
Layering propagation of Eucommia ulmoides is generally carried out in spring; select robust branches of Eucommia ulmoides and press them into the soil, cover with about 15 cm of soil, then firm the soil, and manage water appropriately. In this way, generally after about half a month to one month, Eucommia ulmoides will grow new roots; then when the individual root system is relatively well developed, separate it, and a separate plant is formed, which can then be used for planting.
4. Grafting propagation
Grafting propagation may be a little more complicated. First, we need to select the rootstock for grafting Eucommia ulmoides, and then the scion; the rootstock generally should be two-year-old seedlings, and for the scion it is generally enough to select relatively robust branches of Eucommia ulmoides. Then carry out grafting in early spring; during grafting, disinfect and sterilize to avoid bacterial infection and affect the survival rate of grafting. For grafting Eucommia ulmoides, the most commonly used method is generally 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 your planting afterward will be smoother. Of course, if you have other planting methods, you can also share them with us.
