The breeding method of Yingshanhong

Yingshanhong is a kind of flower with high ornamental value. When it blossoms in spring, it is everywhere, very beautiful and spectacular, and some of them are specially planted in their own courtyard. What are the breeding methods of Yingshanhong?

1. Cuttage propagation

(1) cutting time: choose the cutting time reasonably according to the planting variety.

(2) Cuttage method: choose the branches that are not completely lignified or just lignified for a long time. After cutting it, cut off the leaves at the base of the cuttings, keep about 4 top leaves, and put them in water to prepare for cutting. Then use humus-rich soil around the cutting substrate to keep the cutting mouth smooth and insert it around. After cutting, the cuttings should be watered thoroughly and covered with plastic film to improve the moisturizing capacity of the soil and promote the rooting of cuttings.

2. Striping propagation

(1) crimping time: the crimping propagation of Yingshanhong is mainly high-altitude crimping, which is generally carried out before and after Ching Ming Festival.

(2) the method of striping: select the sturdy, pest-free branches that are about two years old. Then peel the branches around the upper 11 cm, peel off the sieve tube, prevent nutrients from continuing to transport downward, and concentrate on the ring to promote root bud germination. Then wrap the wet soil in a plastic bag or film, wrap it around the ring and fasten the ends of the bag. Then put it in a place where there is no direct sunlight for management, to keep the soil in the bag moist, to promote wound healing and rooting. In about 3 months, after the root grows to about 3 cm, the mother plant can be separated and a separate plant can be formed.

3. Grafting propagation

The main results are as follows: (1) grafting time: grafting propagation is generally carried out around May every year.

(2) grafting method: the two-year-old Yingshanhong plant was selected as the rootstock, and the thickness of the rootstock was not much different from that of the scion. Then cut off the tender shoots of about 4 cm on the mother plant, retain about 4 top leaves, and then cut the base of the tender shoots into wedges. Then cut it short when the new shoot of the rootstock grows to about 3 cm, remove the leaves, cut it longitudinally by about 1 cm, and then connect it to the scion to ensure that the cortex is right to it. Wrap the joint with a grafting film, wrap it in a plastic bag for moisturizing, and put it in a shaded place. After about a week or so, it is found that there are water droplets in the bag and there is a high probability of survival. Remove the plastic bag after 60 days and untie the rope in the spring of the following year.

4. Sowing and reproduction

(1) seed selection: when the seed color of Yingshanhong gradually turns brown, the top of the fruit is cracked, and the seed falls out, it should be harvested in time. And those that are not cracked can not be retained, put them in a cool and ventilated place for storage to promote cracking. Remove impurities from the seed after picking up the seed.

(2) sowing time: sowing around March every year.

(3) sowing method: do a good job of disinfecting the soil, and mix the fine soil properly to improve the germination rate of seeds. When sowing, we should pay attention to the sowing density, cover a layer of fine soil after sowing, do a good job of management, and improve the germination rate of seeds.

Generally speaking, there are four propagation methods of Yingshanhong: cutting, striping, grafting and sowing, of which cutting is the most common and simplest, and the specific methods can be seen in detail.
