The method of breeding all over the sky

The main propagation methods of Mantianxing are cutting propagation and sowing propagation, of which the half-and-half propagation method is cutting propagation.

The method of Cuttage Propagation of Mantianxing

Mantianxing commercial cut flower production, seedling propagation is mainly tissue culture, can also be cuttage,-the propagation of some single-petal available seeds. Most of the plants in southern China are planted in autumn, with about 2000 plants per mu.

The new branches of the plant are cut off about 10 cm in spring, 3-4 cuttings are sprayed in the sand bed to moisturize, take root in about 15 days, and then transplant to the soil for more than 20 days to grow into large seedlings for sale. Take root in about 30 days. Softwood cuttings can be used in the rainy season, select the top softwood cuttings in the current year, and take root 2-3 weeks after cuttage.

The rooting rate of cuttings (qian) is not too high, so it is suitable to choose cuttings with 4-5 pairs of leaves and cuttings treated with rooting powder or other auxins on perlite as substrate, but the best period is from mid-late March to early July and from late September to early November. When the temperature is above 15 degrees Celsius, it will take 20 days to root.

Tissue culture: using stem tip culture, the propagation coefficient is high, the root growth condition is good, the seedling quality is good. Cut flowers are produced by tissue culture seedlings with tall and straight branches, pure color and high quality.

The method of sowing and propagation of all over the sky

Choose loose soil as bed, sow in September, cover fine soil slightly, germinate in about 10 days, and move to cold bed before winter. The optimum temperature for germination is 15-20 degrees. The suitable temperature for growth is 10-25 degrees. Sowing time: early autumn-early spring.

Seedling planting: after living in the sky, the seedlings were transplanted to the open field with soil in the following spring. After the seedlings were planted and survived, the seedlings were harvested for a time to promote their multi-branching. When the height of the plant is more than 20 cm, the amount of irrigation is reduced appropriately, and a little drought can promote flowering, which will blossom in mid-late May.

It is suitable for spring sowing in cold areas and autumn sowing in non-frozen soil areas. The optimum temperature for germination is 21-22 degrees Celsius. The seedlings were unearthed after 7 days and 10 days. After planting, the heart is removed when it grows to about 8 nodes, and when the lateral bud grows to 5: 10 cm, wipe the bud, remove the weak and stay strong. Irrigation frequently at the initial stage of planting, and proper water control when flower buds begin to form.

This species can also be directly broadcast in the open field before freezing in November or sown in early spring.

The method of breeding all over the sky

For commercial cut flowers produced by Mantianxing, the propagation of seedlings is mainly tissue culture, and it can also be propagated by cuttage, and some single-petal species can be propagated with seeds. Today, I would like to introduce the breeding method of Mantianxing.

The method of breeding all over the sky:

1. Tissue culture: using stem tip culture, the propagation coefficient is high, the root growth condition is good and the seedling quality is good. Cut flowers are produced by tissue culture seedlings with tall and straight branches, pure color and high quality.

2. Cutting propagation: the rooting rate is not too high, so it is suitable to choose cuttings with 4-5 pairs of leaves and cuttings treated with rooting powder or other auxins on perlite as substrate, but the best period is from mid-late March to early July and from late September to early November. When the temperature is above 15C, the root can be rooted in 20 days.

3. Sowing and propagation: sprouting on the 10th day of the month under the condition of 21-27 ℃. The sowing time requires that the florescence varies in the morning and evening and is carried out in stages and batches. Sowing at the beginning of September, moving into the cold bed in early winter, planting in the open field in late March of the following year, and flowering from the end of April to the beginning of May.

The breeding method of all over the sky is introduced here. I believe we all know something after reading it.

The culture method of all over the sky.

Originally from the coast of the Mediterranean, Caucasus. Sex likes to be dry, avoid warm and humid environment.

Cultivation techniques

Cutting propagation: hardwood cutting in spring, cutting the mature branches of the previous year 10 to 15 centimeters long, inserted into the sand bed, generally about 30 days to take root. Softwood cuttings can be used in the rainy season, select the top softwood cuttings in the current year, and take root 2-3 weeks after cuttage. When changing the basin every spring, add fresh and fertile soil, keep the basin soil moist during the growing period, and apply fertilizer once every 2 weeks to promote multiple branches and leaves and blossom. Pay attention to pruning the whole plant in autumn to maintain the excellent plant shape.

Cultivation and management: the width of the border is 0.9-1.0 meters, and the length is suitable according to the conditions. There are 2 rows in each row, the plant spacing is 35 cm to 45 cm, and the row spacing is 50 cm. Cross-planting is carried out with 2 000 to 2 500 seedlings per mu. After 30 days of planting, the plant grows rapidly and the demand for fertilizer and water increases, so it should be watered. At the same time, combined with watering and topdressing compound fertilizer containing nitrogen, phosphorus and potassium, topdressing was done every 10 days, and the topdressing was stopped 20 days before flowering. Usually when the seedling grows 7-8 leaves, remove the terminal bud and retain the lower leaf axil. After 2 weeks of coring, the lateral branches grow to 10% m, wipe off the thin buds and retain the strong and consistent buds. Generally, you can keep 1520 flowers per square meter. When half of the florets bloom on the flower branches, they can be harvested. First cut the central flower branch, 60-80 cm long, leaving side branches, harvested in stages and batches.

Viewing and application

The white flowers bloom all over the sky in early summer, and the flowers are luxuriant and well-distributed. Like stars, hazy and charming, but also like trees covered with snow, beautiful and lovely. It is suitable for planting flower beds, roadsides and hedges, as well as potted plants and bonsai production. The full sky star is also an indispensable filling material in the flower arrangement, and several branches of the sky star are inserted into a bunch of flowers, which adds a bit of charming beauty.

The full sky star is the flower that people like. Hundreds of delicate and flawless little flowers gather loosely together, just like the stars in the endless night sky, hazy like fog, with graceful and elegant beauty, breeze blowing, fragrance four Yi, more warm. The flower language is full of stars: pure, far away, romantic.
