Is it easy for Hongfeng to survive after transplantation? What are the planting techniques of Japanese red maple?

Red maple is an important colorful tree species in China, with purple leaves and high ornamental value. Widely used as ornamental trees in gardens, green spaces and courtyards, mainly solitary and scattered. At present, the price of red maple on the market is relatively stable. Generally, a 3 cm sapling can be sold to 20 yuan. So, is it easy for Hongfeng to survive after transplantation? Japanese red maple planting technology, let's take a look!

1. Is red maple easy to survive after transplanting?

1, time

Acer truncatum is best transplanted in dormancy period, because there is less life activity and less body fluid flow during dormancy period, which is beneficial to recovery after transplantation. Generally transplanted from autumn to early spring, Acer truncatum is more likely to survive during this period.

2. Density

In the early stage, Acer truncatum seedlings can be densely planted with a density of 0.8mx0.8m, and about 1000 plants can be planted in one acre, and 6-8kg seeds are needed for Acer truncatum sowing.

3. Survival rate

Red maple has fewer roots when transplanted, so it must have more soil to survive easily. Hongfeng is widely used in urban landscape construction in China. The survival rate of transplanting red maple in spring is relatively high, but some projects with tight construction period need to be transplanted in summer.

Second, the planting techniques of Japanese red maple

1, soil preparation

Acer truncatum likes acidic soil. When planting, you can choose acidic soil with deep soil layer, soft soil and good ventilation and drainage performance, and you can dig holes according to the size of Acer truncatum root system.

2. Temperature

The growth temperature of red maple is between 18-25 degrees, and it has high cold tolerance. It can also overwinter in the open air at the low temperature of MINUS 20 degrees in winter, and has strong cold resistance.

prune

The branches of Acer truncatum grow very fast and will flourish for a period of time, so they need to be pruned regularly every year, usually once in April-May in spring, so that all the side branches, old branches and diseased branches can be cut off.

4. Disease

Leaf spot disease often occurs, which will seriously affect the ornamental value of red maple, and some small white spots will appear on the leaves. Mainly because of the humid environment, it is important to keep ventilation often.
