The latest breeding method of Acer truncatum

The leaves of Acer frutescens are similar to maple leaves, and the crown shows an oval shape. Acer truncatum leaves have very high ornamental value after they are red. Acer truncatum can be seen in many parks in our country, and there is also a certain planting area of Acer truncatum. It is important to breed when planting Acer truncatum, so how to reproduce Acer sinensis? The following editor has brought you the breeding method of Acer truncatum. Let's have a look!

1. Grafting propagation

First of all, a strong and robust Acer mongolica should be selected as the grafting rootstock, and then the grafting work should be carried out when the rootstock is at its most prosperous. First of all, the seedlings should be transplanted for about 3 times, after the rootstocks are defoliated, and the seedlings should be transplanted with soil when transplanting. The main grafting methods are cutting, bud grafting and so on, and various methods have different treatment measures. For example, the cutting is carried out around March every year, and then cut off the rootstock about 60 cm from the ground for high grafting. This kind of grafting method can ensure that the shoot can reach about 55 cm. It is more troublesome to rely on grafting, but its survival rate is relatively high, and the method of budding is carried out for many times, but it is not easy to survive.

2. Sowing and reproduction

The fruit ripening period of Acer truncatum is about October to November every year, and the seeds are taken out from the fruit after ripening. Then deal with the seeds, do a good job of accelerating germination and disinfection, improve the germination rate of seeds and reduce the incidence of diseases and insect pests. After treatment, control the planting density on the planting soil, dig the sowing hole and sow at the right time, cover the soil properly after sowing, and then pour enough water to promote seed germination and emergence. Then cover a layer of grain crop straw to increase the temperature of the soil and prevent water loss. When the seedlings successfully break the soil, it is necessary to remove the straw and do a good job of sun protection, if the seedlings are exposed to direct sunlight, it will seriously affect the growth of seedlings. When the seedlings grow to about 40 cm, they can be transplanted and planted.

3. Cuttage propagation

First of all, the strong and well-growing Acer should be selected as the mother branch tree, and then the cutting branches should be selected. In the week before cutting off the branch, cut off the terminal bud on the branch, then cut it off and put the base of the branch into the water, about 4 cm in the water. Cut the scion into small segments of about 10-12 cm to keep the wound as smooth as possible and retain the general number of leaves. Then use potassium permanganate to disinfect the soil, and then cover the film for 2-3 days for cutting. Pay attention to the density when cutting, pour enough water after cutting, keep the temperature at about 27 degrees, keep the field humidity at 85%, and then fertilize at the right time. Ensure that there is sufficient water and nutrients for the growth of Acer truncatum.

The above three are the brief introduction of the breeding methods of Acer truncatum. There are many breeding methods of Acer truncatum. Cutting propagation is more common, because cutting propagation is relatively simple and the growth cycle is short. It is not recommended to use sowing and reproduction, because the time of sowing and reproduction is very long and is not suitable for large-scale planting. That's all for today's introduction.
