What is the blue witch? how to plant the blue witch?

The blue rose is one of the rose varieties that have undergone cosmetic surgery, because it is not blue itself, but has become blue after being manually processed by science and technology.

First, the origin of the blue witch

"Blue Banshee" first came from the Netherlands as a kind of processed flowers, which is mixed into a colorant with a dye and auxiliary that is harmless to the human body. when the white rose (or white rose) is nearing flowering, it begins to irrigate the flowers with dyes, allowing the flowers to absorb water and inhale the colorant for dyeing.

According to experts, there are few naturally growing blue roses in the world, and the "blue witches" sold on the market are finished products after artificial dyeing. The regular "blue demon" begins to dye during the growth period, and the color can be uniformly attached to the petals, which looks more natural; there are also bad vendors who directly dye ordinary white roses directly into blue roses, not only the color distribution is uneven, and it is very easy to fade. We must pay more attention to observation when buying.

It is said that the Australian branch of Suntory of Japan began to cultivate blue flowers such as blue roses and blue carnations in 1990. The first batch of transgenic blue roses were successfully cultivated in the laboratory in 2004. scientists extracted the blue pigment gene from blue clover and used gene recombination technology to change the genetic factor arrangement of roses. The petals of this rose contain blue pigment with a purity of nearly 100%.

Second, the main role of the blue witch

Watch: blue rose, also known as the blue witch, it belongs to the upstart in the flowers, flirtatious and charming, but also means to keep each other is a commitment.

Pigment: the blue witch is a colorant mixed with a dye and dye aid that is harmless to the human body. when the white rose or white rose is nearing flowering, it begins to irrigate its flowers with fuel, making the flowers as if they are absorbing water. the dye is inhaled to achieve dyeing. According to flower experts, we introduce very few naturally growing blue roses. The blue witch sold on the market is basically the product of artificial dyeing, while the more formal blue witch begins to dye during the growing period of flowers, and the color will be more natural and not easy to fade. There is also a blue witch covered with blue gold powder, the color is not natural and is easy to fade and not easy to preserve.

Third, the planting method of the blue witch

Planting: cuttings are selected from one-and-a-half-lignified branches with short and sturdy nodes that are not heading, and cut off at the top 8-10 cm as cuttings. The incision should be close to the stem node, and the callus anticorrosive film should be applied around the incision to protect the integrity of the phloem, and the cuttings should be soaked with 800-fold solution of new high-fat film (to prevent wound decay, virus infection, restore plant physiological vitality, and promote germination and rooting).

Land selection and land preparation: the blue witch likes sunshine, heat resistance, cold resistance, hail resistance and saline-alkali resistance. Before planting, she should select a good plot, apply sufficient base fertilizer, irrigate enough water, prepare the land, make beds according to the requirements, and do a good job in the treatment of soil diseases, insect pests and weeds. Planting method: the blue witch has direct broadcast and cymbal insertion, which is mainly used in production, which is generally selected in spring.

Because the blue witch itself is not a natural rose variety, but is dyed by white roses and roses, so when planting, you can choose the planting method of white roses, and then send the flowers to render.
