How should hydrangea reproduce? Propagation method of Hydrangea

Hydrangea is a kind of shrub plant of Saxifragaceae, and its cultivation time is relatively early in China. At present, most parks in our country are inseparable from the embellishment of hydrangea, which also forms a beautiful landscape. Its ornamental value is very high, and now it has a large cultivation area in our country. However, when we are cultivating hydrangea, we should do a good job in breeding, so the editor has brought you the breeding method of hydrangea today, let's take a look!

1. Ramet propagation

The common propagation method of Hydrangea is ramet propagation, which is relatively simple, and the rooting survival rate is relatively high. The ramet time of Hydrangea should be chosen at the time of sprouting in early spring. First of all, we should choose a strong plant free from diseases and insect pests, and then select the branches that have already taken root. If it is separated from the mother plant, it can be planted directly into a pot, and then properly watered to shade. However, watering should not be too much to avoid the branches from rotting, and when the branches sprout new buds, they can be maintained normally.

2. Striping propagation

Striping propagation is also a common propagation method in the planting of hydrangea. Compared with ramet, striping propagation is a little difficult to operate, but the survival rate is also relatively high. Striping propagation can generally be carried out throughout the year, but it mainly depends on the sprouting of new shoots. To press the new bud when it is sprouting, select a strong branch, then cut it around to the xylem, then wrap the wet sand at the ring cut and tie it tightly. It can grow in about a month or so, and it can be separated in the spring of the following year and transplant with soil. if it is carefully protected, it can blossom that year.

3. Cuttage propagation

In addition to ramet and striping, Hydrangea can also be propagated by cutting. In fact, the success rate of cutting propagation is also relatively high, but it is not suitable for large area planting. The time of cutting propagation is generally carried out in the annual plum rain season, first of all, high-quality branches are selected. Cut off the top twigs and keep the length at about 20 centimeters. Then cut off the leaves at the bottom of the cuttings and apply the rooting agent appropriately. Then the cuttings are directly inserted into the sand bed, and the temperature is controlled at about 15 degrees, which can take root in about half a month.

4. Tissue culture propagation

Tissue culture is troublesome to operate, but it is not a high-quality method of propagation. First of all, we have to select dormant buds from the plant as explants. Then it was routinely sterilized and inoculated, and then an appropriate amount of benzylaminoadenine and indole acetic acid was added to the culture medium to promote the formation of adventitious buds. When the seedlings grow to about 3 cm high, they can then be transferred to the medium of indole acetic acid to promote the growth of complete plantlets.

The above is a brief introduction to the breeding methods of hydrangea. There are many breeding methods of hydrangea, and we should choose the appropriate breeding method according to the actual situation. That's all for today's introduction.
