The reproduction of a string of red

1. Sowing and reproduction

The potted soil is prepared before a large string of red seeds are planted, usually in March, and can be sown indoors in areas with lower temperatures. Pour the pot soil thoroughly, leave it for 1-2 days and then sow. Sprinkle the seeds evenly on the soil surface and cover with 1-2 cm of soil. Do not need watering, you can cover the basin with plastic film to increase humidity.

A short string of red seeds is usually planted outside the sowing room in August, prepare the pot soil in advance, choose the soil with good drainage, loose and fertile soil, and add a small amount of organic fertilizer to the soil. Water thoroughly and set aside. Spread the seeds evenly in the basin and cover with 1-2 cm fine sand. 2-3 days later, cover with a layer of fine sand. After 6-7 days, the seeds can germinate and seedlings will grow in 10 days.

If you encounter a rainy day, you should cover it with another layer of soil to avoid rain. 5-6 leaves will grow in late September, and the plant will be moved indoors for maintenance.

2. Cuttage propagation

Select a strong plant, cut 12-15 cm branches from June to July and put them in a cool place. Prepare the potted soil and insert the branches in the basin, usually 1-2 branches in a pot, immediately after planting, watering shade to reduce water evaporation. Keep the temperature around 20 ℃ and spray water 2-3 times during the day. The branches can take root and sprout in 3-5 days, and then gradually transfer to the sun.

The breeding method of a string of red when will a string of red bloom

A string of red, also known as firecracker red, is a plant of the genus Salvia of Labiatae. When will a bunch of red blossom? Let's take a look at the answer and a string of red breeding methods.

The breeding method of a string of red:

1. Cutting method

The propagation of a bunch of red by cutting can be carried out from May to August in summer and autumn. Cuttings take twigs with full tissue, remove the terminal buds and then plant them, which is easy to take root. In the summer high temperature and dry season, pay attention to shade cooling, often spray water, keep moist, about 15 days can be transplanted, is a relatively fast and relatively simple string of red breeding method.

2. Cultivation method

A string of red reproduction can also be carried out by cultivation, with a planting distance of about 40 cm, preferably in fertile, loose, humus-rich soil or sandy soil. A string of red in the growing season, can be applied phosphate liquid fertilizer 1 to 2 times, to promote flowering. A string of red usually do not like flood, otherwise it is easy to produce yellow leaves, fallen leaves, resulting in large plants and sparse flowers. During the growth period, plastic surgery should be often removed to control the height and branching of the plant. Cause the inflorescence to grow and enlarge and blossom neatly.

3. Sowing method

Sowing method is also a common breeding method of string red. In the south, it is usually the best time to sow seeds in a string of red open fields from late March to early April. The sandy soil with good drainage conditions is selected as the seedling bed, and the border surface is loosened, broken and flattened. Let it be exposed to the sun for a few days, and then disinfect the seedling soil with potassium permanganate solution. Sow a bunch of red seeds on the seedbed, and then sprinkle an appropriate amount of carbofuran on the seedbed (the drug can kill ants, earthworms and other pests, without any harm to the seeds). Usually keep the seedbed moist, seedlings can emerge in 6-7 days under the condition of 16 ℃-21 ℃, and pot seedlings can be transplanted when 3-4 true leaves are planted.

When will a string of red blossom:

A string of red is a perennial herb or subshrub for annual cultivation. Red flowers, flowering in summer and autumn. A string of red can use short-day treatment and coring to control the flowering period of a string of red. Short-day sunshine is beneficial to the differentiation of a string of safflower buds. If sowing early in spring, short sunshine is beneficial to reproductive growth, while seedlings sowing later can be shaded sooner or later to promote early flowering. It usually shines for 8 hours a day and blossoms after 57 days. If the light is 16 hours a day, it will blossom after 82 days.

In addition, timely coring can also control the flowering period, generally can be picked twice, the second should be in late August, leaving 16 branches 20, it is expected to blossom on National Day.

Sowing and breeding method

Sow seeds with red bunches

Prepare potted soil before planting, usually in March, and sow indoors in areas with lower temperatures.

Pour the pot soil thoroughly, leave it for 1 or 2 days and sow the seeds.

Sprinkle the seeds evenly on the soil surface and cover with 1cm or 2cm of soil. Do not need watering, you can cover the basin with plastic film to increase humidity.

Short string red sowing

Usually potted outside the sowing room in August, prepare the pot soil in advance, choose the soil with good drainage, loose and fertile soil, and add a small amount of organic fertilizer to the soil. Water thoroughly and set aside.

Spread the seeds evenly in the basin and cover them with 1 cm of fine sand. 2-3 days later, cover with a layer of fine sand. After 6-7 days, they can germinate and seedlings will grow in 10 days.

If you encounter a rainy day, you should cover it with another layer of soil to avoid rain. 5-6 leaves will grow in late September, and the plant will be moved indoors for maintenance.

Cuttage propagation

Select a robust plant, cut 12cm branches from June to July and put them in a cool place.

Prepare the potted soil, insert the branches in the basin, usually 1 or 2 branches in a pot, water shade immediately after planting to reduce water evaporation. Keep the temperature around 20 ℃ and spray water 2 or 3 times during the day.

The branches can take root and sprout in 3 to 5 days, and then gradually transfer to the sun.
