Seed planting method of blue thorn head

selection matrix

Because the vitality of the blue thorn itself is very tenacious, its adaptability to the environment is also very strong, so it can also adapt to different planting substrates. The soil must choose sandy soil with good air permeability and strong water retention ability. Because blue thorn head is very afraid of waterlogging, waterlogging for a long time will lead to root rot, so the soil must not accumulate water for a long time. It is not necessary to apply a lot of fertilizer when planting, and the nutrients in the soil are generally sufficient to ensure its normal development.

selection context

Blue thorn prefers cool, airy environments and cannot grow in hotter areas. If you choose potted plants, it is best to adjust the temperature indoors and avoid summer sun exposure. The best temperature is 20 to 25 degrees, choose a sunny place to plant, can not choose too dark environment.

planting method

First, prepare a container, the size of which depends on the number of trees planted, pour the soil into the matrix, and flatten it with a shovel to ensure its permeability. Then slowly place the seeds on the soil, cover them with a layer of substrate, and then pour a small amount of water to ensure that the soil is moist and give the seeds a suitable germination environment.

If there are flower friends who choose to plant, first of all, dig several small holes in the selected planting place, put 1 to 3 seeds in each hole, pay attention to the small hole can not be dug too deep, 1 to 2 cm is enough, gently put the seeds into the dug small holes, cover the seeds with a layer of substrate, and moisten the soil with a shower. If you choose a large number of flowers planted in the ground, it is recommended to deeply plow the land, irrigate the ground with sufficient water, and finally sow seeds.

After learning how to plant these bluethorn seeds, do you know what other breeding methods bluethorn has?

Breeding method of blue thorn

Seed propagation of Echinops nigra

The optimum temperature for seed germination is 20℃~25℃, and the emergence rate is high. This method can get a large number of plants, but this method will make the offspring characters separate, which will reduce the ornamental quality of Echinops occidentalis to a certain extent.

Cuttings of Echinochloa glauca

The roots of C. nigrum have strong regeneration ability. A large number of adventitious buds can be obtained by cutting roots, and the traits of the progeny obtained by cutting propagation are relatively stable.

The suitable soil for cuttage of C. nigrum could be selected by mixing substrate, river sand and peat in the ratio of 1∶1∶1, and then cutting the root segment into 2~3cm length. Root segments are inserted into seedling trays and covered with plastic film to create a microclimate to maintain humidity.

In the greenhouse, about 10 days, the upper end of the insertion section will form callus, white, and then will differentiate adventitious buds, about 20 days, the lower end will differentiate adventitious roots; in the open air propagation can be carried out in March of spring, cutting seedlings grow for about two months, can be planted. Select a well-drained area for planting, and then irrigate it thoroughly. Pay attention to intertillage and weeding in the later stage, properly control the watering amount and watering frequency, and drain it in time after rain to avoid ponding.

Tissue Culture of Echinops nigra

The tissue culture propagation of Echinochloa nigra is mostly used in scientific research and large-scale production, which can realize rapid propagation and screening of excellent varieties of Echinochloa nigra, screen virus-free plants, maintain original excellent characters and stably inherit; in addition, new varieties can be bred by mutation by tissue culture technology. However, it should be noted that the seedlings of tissue culture are relatively weak. If they need to be transferred to field cultivation, they need to be refined in the early stage to enhance the adaptability of seedlings.

The ecological habits of blue thorn head are strong adaptability, drought resistance, barren resistance, cold resistance, cool climate and sandy soil with good drainage, avoid heat and wet waterlogging, and can be extensively managed. Is a good summer flower perennial flowers. Blue thorn head cultivation techniques Blue thorn head can adopt seed propagation, root cuttings and tissue culture propagation methods. 1. Seed propagation is simple, the seeds of Echinops nigrum germinate easily at 20℃~25℃, and the emergence rate is high, but the characters of the offspring obtained by this propagation method are separated greatly, which reduces the ornamental quality of Echinops nigrum. 2. The roots of root segment cuttings have strong ability of adventitious bud regeneration. A large number of adventitious buds can be obtained through root segment cuttings, and more stable progeny can be obtained through cutting propagation. Generally, root cuttings are used to reproduce, which can maintain the excellent characteristics of the mother plant. The method was: substrate: river sand: peat =1∶1∶1, root segment was cut into 2~3cm length. After rooting, plastic film can be covered on the seedling plate to maintain humidity. After 10 days, white bulged calli were formed at the upper part of the insert, then adventitious buds were differentiated, and adventitious roots were differentiated at the lower part after 20 days. The method can be carried out all year round in greenhouse, or in March in spring if it is open field, and the cuttings can be planted after two months of growth. Select the well drained area according to 40cm×40cm plant spacing planting, and then irrigate once permeable water. Pay attention to intertill weeding, properly control watering, timely drainage after rain. 3. Tissue culture The technology of tissue culture can be used for industrial production, realize rapid propagation of excellent varieties of blue thorn, obtain virus-free plants, keep the original excellent characters unchanged, and cultivate new varieties by tissue culture mutation. Cultivation: suitable for planting in the sun foot, good drainage soil. The distribution area of blue thorn head is distributed ** Tianshan area. Born on the edge of a hillside forest or canal. It is widely distributed in the Soviet Union (Central Asia, Caucasus, Siberia), Central and Southern Europe.

The garden use of blue thorn head as an ornamental plant, blue thorn head also known as blue planet, color is blue-gray, shape has "single head type" and "multi-head type" two kinds, can also be made into natural dried flowers (must first remove a part of the leaves, upside down in the ventilation place, a week to complete drying). At present, the plant is less used in China. However, due to its unique flower shape and color, I believe that in the near future, it will be deeply loved by Chinese people. The role of blue thorn 1. Flower decoration blue thorn can be used as fresh cut flowers and dried flowers. Due to its peculiar flower type, colorful and rich colors, and long viewing period, it can be applied to flower decoration in families, hotels and restaurants. After its cut flowers are listed, they are loved and recognized by consumers, especially foreign friends, and are expected to enter the international market. 2. Landscape application Blue thorn is a wild flower endemic to high altitude grassland and mountain area. After introduction, it shows the characteristics of extensive management, strong adaptability and low maintenance cost. Moreover, it has high ornamental value such as colorful flowers and unique inflorescences. Therefore, it has a very broad application prospect in landscaping. Ornamental blue thorn planted per plant has beautiful plant type, its flower stalk is extracted from leaf cluster, and there are many branches, ranging from 3 to 12 branches; the number of flower bulbs is few, and the number of flowers reaches 40; the diameter of flower bulbs is 4~8cm; the colors are blue, blue-purple, white and other colors; the single plant is planted in lawn green land, road corners and other places very eye-catching, attracting visitors 'attention. Because the ground part of blue thorn gradually withers after flowering, it should be paid attention to planting reasonably with other plants to create a continuous landscape. Scirpus communis has good cluster character, and its root has strong ability of regeneration adventitious bud, and it will present a kind of cluster landscape after a few years. The blue thorn grows in the lawn green land or under the sparse forest, which makes the dull green space full of wild interest and gives people the psychological satisfaction of being close to nature. Planted as a flower border; planted along both sides of the road. Softens stiff road curves and avoids regular hedge lines. If planted with evergreen shrubs, it can create a variable landscape, far better than the single shrub green belt planting form. In addition, planting flower beds can also meet the needs of diverse colors. With the rapid development of urban landscape construction, ground cover plants, as a carrier of landscape and ecological functions, are increasingly valued by designers. As a ground cover greening plant, Echinops nigrum L. has many excellent characteristics. It has wide ecological distribution, strong adaptability and resistance, can grow well in arid and barren land and hillside sparse forest, and can be viewed for many years once planted, greatly saving management costs. It can be planted in flower bed, flower border and slope protection of mountain, especially in sparse forest space, which can not only reasonably use space, but also create continuous landscape, so it has great development potential as a ground cover greening material.
