How to reproduce delphinium, what are the propagation methods / sowing / cutting

Delphinium is a kind of flower plant originating in Europe, which was introduced to China. Nowadays, there are many people planting it in our country, but with more and more people growing it, people are more concerned about its reproduction. So how does delphinium multiply? What are the breeding methods of delphinium? Next, the editor will take you to learn about it.

First, how does delphinium multiply

About how to reproduce swallow grass, there are two commonly used methods: sowing reproduction and cutting propagation. These two methods have been tested countless times, and the survival rate is still relatively high. As for how these two propagation methods need to be operated, the details are below. Let's move on.

Second, the propagation method of swallows.

Sowing and reproduction

1. Sowing time

In the breeding method of delphinium, sowing and reproduction is a commonly used method, but there are many places that need to be paid attention to. The time of sowing is very important. Choosing a correct time for sowing can greatly improve the survival rate. The appropriate sowing time is from August to September of each year.

two。 Seed germination

Before sowing swallows, we need to soak the seeds in warm water for a day, and when the seeds begin to absorb water and swell, we can take them out and sow them, which can promote the germination of the seeds.

3. Sowing method

Compared with cuttage propagation, sowing and reproduction is a little more complicated in the breeding method of delphinium. First of all, we should evenly sow the seeds of delphinium and fine sand, then cover them with 1-2cm soil, and then water them. When watering, pay attention to watering thoroughly, about 7-12 days after watering can sprout.

Cuttage propagation

1. Cuttings selection

Before the cuttage propagation of delphinium, we should first choose the cuttings, that is, the branches of delphinium. We had better choose the branches with strong growth and no diseases and insect pests, so that the survival rate will be greatly improved.

two。 Cutting method

Among the propagation methods of delphinium, cutting propagation is relatively simple. when cutting, we can first use chopsticks to cut a hole in the soil, and then insert the cuttings, so as to avoid the damage to the cuttings. after that, the soil can be flattened and watered once, and then it can take root in about 15-20 days.

What are the breeding methods of swallows?

The mode of reproduction of delphinium: sowing

The optimum temperature for swallow germination is about 15 ℃, and the best soil temperature is below 20 ℃, which will germinate in about two weeks.

Autumn sowing in late August to early September, first sowed into the open field seedbed, before winter into the cold bed or cold room to winter, warm spring planting. The seedlings were directly broadcast in the open field in early spring in the south, and the distance between seedlings was kept at 25cm.

In the north, seedlings are generally raised beforehand and planted in April, 2-4 true leaves and 4-7 true leaves. Pay attention to drainage on rainy days.

The soil must be kept moist after sowing. The easiest way is to cover some grass and gradually remove the mulch after emergence.

The propagation mode of swallows: cuttings

The cuttage propagation of delphinium is carried out in spring. When the new branch grows above 15cm, the cuttings are cut and inserted into the sandy soil.

Do not rush to water after inserting sand. Water properly after 2-3 days.

The mode of reproduction of swallows: ramets

It can be carried out in both spring and autumn. When the new buds grow to 15-18cm in spring, they can be transplanted after rooting, and the new branches at the base can also be cut after flowering.

Ramets should pay attention to fate, some delphinium does not grow new buds for 3 years, and some delphinium grows a lot of seedlings in a year to cling to the base of the mother plant.

Ramet is usually carried out once every 2-3 years, otherwise it is easy to lose the vitality of the mother plant. Just after Mother's Day, we also give more care to the mother plant, so that she can spend more time with the children, so that the children will be strong after they are independent.

Whether it is the use of sowing, cutting or separate propagation of delphinium, we should pay attention to the lodging of plants. The main stem of swallow plant is tall, easy to grow without light, easy to lodge or bend the main stem, after growing to a certain stage, we should pay attention to support and fix, you can use twigs and sticks or small bamboo poles to gently bind the main stem. Remember not to push hard to avoid hurting the stem skin.

Introduction to the propagation method of swallow grass

Swift grass can be used for flower bed decoration and edge greening, and can be cultivated in pots or containers. In general, delphinium can be propagated by sowing, cutting or ramet. The editor will introduce you to the breeding method of delphinium, and friends who like it can learn about it together.

Swallow grass

There are many seeds in the fruit, and the seeds are small, which are collected and dried and stored in a cool and dry place in the room. In order to blossom in many seasons, the seeds can be sown by stages, but the cultivation in the south should stagger the flowering period in midsummer and hot days. Delphinium is a straight-root plant with few whisker roots and is not resistant to transplantation. In the south, the winter can be overwintered by direct broadcast in autumn or spring. The cold regions of the north should be sown in spring; autumn sowing in the warm areas of the north can cover the open field for the winter, or need to move cold beds or low-temperature greenhouses to survive the winter. Sow seeds in a seedling tray, pour enough bottom water, sow about 20 grams per square meter of seedling bed, and control the suitable temperature. the germination time of delphinium seeds is one of the longest species of herbaceous flowers in the open field in 2012, which usually takes 15 minutes and 20 days. After emergence, the seedlings should be transferred to a container (7-8 cm in diameter) as soon as possible.

In addition, perennial swallows of the same species can also be propagated by cuttings and ramets. Cutting seedlings are raised in spring and picked and planted in wet sand beds or sand tables. Ramet can be carried out in spring and autumn, the seedlings germinated around the old plant, dug up with roots, divided into small plants, if the spring ramet can blossom in the same year.
