The Culture method of Elm Leaf Prunus mume (Xiao Taohong)

Elm leaf plum, also known as peach red and elm leaf twig, has a long history of cultivation and high ornamental value in our country, and it has been planted in many parks in our country. So, what is the breeding method of elm leaf plum? Let's get to know it together.

I. growth habits of Prunus mume

The branches of Prunus mandshurica are purplish brown, the leaves are wide oval to Obovate, the flower is single to double purplish red, the drupe red is nearly spherical, the elm leaf plum is light-loving, slightly shade-tolerant, cold-resistant, can survive the winter at a temperature of-35 degrees, and is not strict with soil. It is better to have neutral to slightly alkaline and fertile soil, with well-developed root system, strong drought resistance, but not waterlogging resistance and strong disease resistance, growing on slopes or under trees, shrubs or forest margins at low to medium elevations. In China, it is mainly distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Shanxi, Shaanxi, Gansu, Shandong, Jiangxi, Jiangsu, Zhejiang and other places.

2. Propagation methods of Prunus mume.

1. Grafting

There are two grafting methods of elm leaf plum: bud grafting and branch grafting. Bud grafting should be carried out in mid to late August. Rootstocks can use annual seedlings of elm leaf plum, or seedlings of wild rose, hairy peach or mountain peach. Bud grafting can be used to cut full leaf buds from annual branches from excellent varieties of elm leaf plum. Branch grafting should be carried out in February-March in spring, and scions should be intercepted before the plant sprouts. Winter tenacity can also intercept scions and store them in sandy soil for use in spring.

2. Cuttage

Elm leaf plum often uses the same year's branches for tender wood cutting in late spring and early autumn, or uses last year's branches for old branch cutting in early spring. When the plants are growing vigorously from late spring to early autumn, the sturdy branches of the current year are selected as cuttings. After the branches are cut off, the sturdy parts are selected and cut into a section 5-15 cm long, each section with more than 3 leaf nodes. Hardwood cuttings are cut after the temperature rises in early spring. Select last year's strong branches as cuttings, each cuttings usually retain 3-4 nodes.

3. Pressing strip

Select a sturdy branch and peel off the bark from about 15-30 cm below the top. The width of the peeled wound is about one centimeter, and the depth is limited to just peeling off the epidermis. Cut a piece of film 10-20 cm long and 5-8 cm wide, put some wet garden soil on it, wrap up the ring peeling like a wound, bind the upper and lower ends of the film tightly, bulge in the middle, and take root after about four to six weeks.

4. Sowing seeds

After maturing, the seeds of Prunus mandshurica can be sowed in autumn or in spring after sand storage, and can be planted after defoliation in autumn to before bud germination in early spring. Pruning and fertilization should be paid attention to in cultivation and management to ensure that there are enough flower branches in the coming year.

3. Culture methods of Prunus mume

1. Soil

Prunus mandshurica is not strict with the soil, so it is not resistant to waterlogging, so it is suitable to be planted in neutral to slightly alkaline, fertile and loose sandy loam.

2. Watering

Elm leaf plum avoid waterlogging, in spring planting, if the weather is dry, should be watered 2-3 times, usually do not need watering, at the same time, we should pay attention to rainy season drainage, if waterlogging damage is very easy to rot roots, affecting the growth of elm leaf plum.

3. Sunshine

Elm leaf plum in autumn, winter, spring three seasons can give sufficient sunshine, when indoor maintenance, as far as possible in places with bright light, such as well-lit living room, bedroom, study and other places, summer breeding when the sun is too strong will burn leaves, it is best to do a good shade treatment.

4. Temperature

The elm leaf plum likes the warm climate, the general spring and autumn season is very suitable for its growth, but the summer high temperature, muggy environment is not conducive to its growth, the winter temperature requirements are very strict, when the temperature below 10 degrees will stop growing, can not survive the winter safely under frost, so winter breeding must pay attention to heat preservation.

5. Insect pests

The main diseases and insect pests of Prunus mandshurica are brown spot, white feather, aphids, diamondback moth, red spider, roll leaf moth and so on, which generally occur in summer and autumn.

6. Pruning

In the process of the growth of elm leaf plum, it is especially necessary to pay attention to the exhaustive pruning of the branches, and after the flower fade, it is necessary to make a moderate short cut of the flower branches, leaving 3-5 buds on each strong branch, and then pruning again, and topping and peeling, so that nutrients are concentrated, which can promote flower bud germination.
