How to plant a bunch of red, how to plant a bunch of red

1. Reproduction methodA bunch of red is propagated by sowing or cuttings to sow more. The sowing season in North China is not limited, and the rest of the region is suitable for spring. A bunch of safflowers is late, spring sowers 9 October flowering, if you want to advance the flowering period or harvest the seeds, the seeds should be sown in a greenhouse or hotbed in early March.

A small amount of basal fertilizer is applied in the seeding bed, the bed surface is leveled and watered thoroughly, sowing is sown after water infiltration, covered with a thin layer of soil, and the seeds germinate 8 to 10 days after sowing. It blooms in about 100 days and blooms for about two months. Cuttings are mostly used with shoots, and it is more suitable to take March 5 or 9 October, combined with the picking of top buds.

2. FertilizationBasal fertilizer is required for planting sites or potting soils.

3. WateringIn order to prevent overgrowth, it is necessary to water less, loosen the soil frequently, and apply top dressing <>

Speaking of how to plant a bunch of red, first of all, we must choose to sow from March to June every year, and then prepare suitable soil, control the temperature and moisture after sowing, not too dry, otherwise it will cause a bunch of red germination is very slow, and after it grows 6 true leaves for division, it can be transplanted into pots.

A bunch of red sowing time is generally in late March to early June every year, this period can be sown, pay attention to the sowing to avoid rainy days, rain will affect the germination of a bunch of red seeds and the growth of seedlings.

Before planting, it is necessary to choose the appropriate culture soil, generally choose to use garden soil, rotting manure, bean cake and other amounts of mixture, so that the soil is loose and fertile, good water retention and water retention, and top dressing after planting, which can make a bunch of red branches and leaves flourish.

Bury a bunch of red seeds in the substrate and cover it with a thin layer of medium, preferably coarse vermiculite. No fertilization is required, and radicles can grow after 4-5 days.

After sowing, the temperature should be kept at 24 26, if there is enough light, it is better to help germinate and grow with seeds. It is advisable to keep the potting soil moist and not too dry.

According to the above steps to plant, generally 8 10 days after sowing can germinate, wait until the seedlings grow 2 3 true leaves for transplantation, 6 true leaves when the topping, can promote the growth of more branches, at this time can be potted for transplanting.

Ground planting should be selected in a well-drained place, and manure should be applied before planting. Plant row spacing 30-45cm. The potting soil is mixed with 4 parts garden soil, 3 parts humus, 2 parts of sand and 1 part of manure.

Flowers can be potted in mid-May for October use. The basin diameter is 25 30cm, and the horseshoe horn piece or hemp residue is used as the bottom fertilizer. 1 plant per pot.

In the growth period, 3 to 6 times of topping and budding should be carried out for ordinary varieties to promote their multi-lateral branches, and the topping and budding should be stopped about 25 days before the scheduled flowering period.

It will be ready to bloom after 35 days. Water once a day on sunny days in summer, preferably in the early morning or evening. Apply thin liquid fertilizer once every 2 weeks.

May Day flowers, should be potted indoors, maintain room temperature 20 zhang during the day, 15t at night, watering to see dry and wet. Re-pruning is feasible after flowering in May. Cut off half of the branches and maintain them so that they can bloom again in October.

To bloom on the National Day, you can use the spring sowing seedlings of the same year, use the method of topping and budding, control the flowering period, stop picking buds around September 5, and reach full bloom before and after the National Day.

The fruit is easy to fall off when ripe, and when the calyx is whitish, pay attention to timely harvesting. When harvesting, the inflorescence can be covered with a large paper bag and vibrated to make the mature seeds fall into the bag, so that the seeds are received and the flowering period is extended. After the seeds are harvested and dried, they are stored in a cool place.

During the growth period, the red butterfly is often harmed by hot and poor ventilation, which can be killed with dicofol with 1000 to 1500 times of water. Aphids can be eliminated with 1000 times of dimethoate water.

Whiteflies can be killed by adding 1000 times more water to the enemy, and then adding a small amount of Tween shake spraying to kill.

A string of red is also called ivory red, bursting red. If you listen to its name, you can tell that its flower color is very bright, it is red, and it is very festive. The fruit is a small nut with oval shape and black seeds. When the seeds are ripe, they can fall off on their own and reproduce on their own.

<>2. Land preparation: Choose a sunny area for sowing, and the soil requirement is sandy soil with good drainage. After selection, the soil should be turned over, the soil ball should be broken, leveled, and then exposed to the sun for a few days and disinfected with potassium permanganate solution. Be sure to disinfect before sowing, otherwise it will affect the emergence of seedlings.

3. Sowing: After the soil is prepared, the seeds can be scattered on the surface of the soil, and they should be sprinkled evenly, and then sprinkled with an appropriate amount of insecticides, just use carbofuran.

4. Maintenance: Keep the seedbed moist in the later stage, provide an environment of about 16 degrees to 21 degrees, and the seedlings can emerge in about a week, and they can be transplanted when three or four true leaves grow.

A bunch of red seeds should be planted in March every year, select the seeds with full appearance and no damage and soak them in warm water for 12 hours in 21 24, plant them in the sandy soil with good ventilation and good drainage, control the growth temperature at 20 25, water every 7 10 days and apply thin fertilizer every 10 15 days during the growth period.

When many people ask how to plant a bunch of red seeds, they must first know that a bunch of red seeds need to be planted in March every spring, and the climate in this time period is particularly suitable for the growth climate of a bunch of red, which is suitable for seed germination and healthy growth of plants.

When planting, it is necessary to select seeds with full appearance and no damage to soak them in warm water at a temperature between 21 and 24 for 12 hours, and then clean the surface of the seeds to avoid impurities affecting seed germination, which is conducive to the healthy development and growth of seeds.

The choice of soil for seeding requires a sandy soil that is loose, breathable, well-drained, and rich in nutrients as the base bed for seed planting. It can be planted with a mix of sandy and humus soil and manure in a 4:3:3 ratio to allow the seeds to germinate and grow better.

A bunch of red is not cold tolerant like warm environment of the plant, after the seed planting germination to ensure that the growth temperature is between 20 25, the temperature below 15 will cause the growth of the plant to slow down, resulting in the yellowing of the leaves of the seedlings and fall off, the growth temperature above 30, it will cause the growth of the leaves too small.

After the seeds germinate, they need to be watered every 7 10 days during the growth period, and they should be watered according to the actual situation to avoid water accumulation, which will lead to rotten roots and affect the growth; In the growing period, it is necessary to apply thin liquid fertilizer every 10 15 days or so to avoid root rot caused by excessive fertilizer concentration, and ammonium lucrate can also be diluted 1500 times and sprayed, which can make the leaf color more green and shiny.

Basal fertilizer is required for fertilization of planting sites or potting soils.

Watering In order to prevent overgrowth, it is necessary to water less, loosen the soil frequently, and apply top dressing.

Temperature, light.

The optimal growth temperature is 15 30 , below 12 growth is stagnant, the leaves turn yellow and fall off, and the flowers gradually fall off. If you plant a bunch of red in a greenhouse, if you have high temperature, high humidity or insufficient light indoors, it is easy to rot disease, and you must pay attention to adjusting the temperature to make the air circulate. In addition, a string of red is prone to insect pests such as red spiders and aphids, and can be sprayed with 1500 times of dimethoate emulsion for control.
