A string of red, also known as western red, ivory red, etc., is a very beautiful flower, often cultivated in one or two years.

How to choose a bunch of red seeds?

Yihong is one of the main flower materials in flower bed and flower border in China, which is mainly red dwarf type, and its color and plant type are relatively single. The excellent varieties of white, pink, orange, purple and complex color introduced abroad are basically dwarf plant type, and the seed price is higher. Of course, there are some newly approved varieties, the ornamental effect is unique, no pruning, should be extensive management, especially suitable for flower beds, flower border application. Therefore, when choosing seeds, we must clearly recognize the varieties and synthesize all aspects of the actual conditions, which is conducive to the follow-up planting work.

What are the methods of raising seedlings?

1. Sowing and raising seedlings

A bunch of red seeds per gram 250-280, generally choose 200 or 288 hole plate, sowing medium generally choose imported seedling soil or sterilized domestic seedling soil, matrix PH:5.8-6.2 ECRV 0.5-0.75, need to cover soil after sowing, generally 6-7 days seed germination, the temperature is best maintained at 20-25 ℃.

2. Seedling management

The radicle appeared in the first stage of germination within 4-5 days. It is necessary to maintain proper moisture, but not soaked, and the substrate temperature is 22-24 ℃ to provide light for 100Lux.

The second stage of germination: cotyledons grow completely. The substrate should be slightly soaked but not soaked. After the emergence of cotyledons, the temperature dropped to 20-21 ℃, generally without fertilization.

Germination stage 3: the first true leaf appears. It is necessary to keep moderate moisture, improper watering can lead to early flowering, temperature control at 18-20 ℃, and application of about 3500 times 14-0-14 or 20-10-20 alternately.

Germination stage 4: drooping leaves indicate that the substrate is too dry, the EC concentration is too high or the temperature is too low. When the root system is basically formed, when there are two true leaves, the moisture and temperature are in the same three stages and pay attention to ventilation, which can make the plant more robust and prevent overgrowth.

3. Transplant into pot

When there are 3-4 true leaves, you can go to the basin, generally choose the nutrition bowl above 13cm, and the substrate generally choose garden soil plus organic fertilizer and compound fertilizer. When transplanting seedlings, it is best to let a string of red new roots bring more matrix to slow down the seedlings. It is necessary to use a shading net to cover the shade in order to shorten the slow seedling period. After about 10 days, remove the shade net and let the plant receive all-day sunlight.

4. Pest management

The main disease is mosaic disease, which can be sprayed with stomach poisons such as 1000 dichlorvos, 90% trichlorfon and 80% dimethoate emulsion. The main pests are red spiders and planthoppers, which can be sprayed with 2% dicofol 1000 times or 40% monocrotophos 2000 times, once every 5 to 7 days.

After a string of red blossoms fail, the petals contain some small seeds, and the seeds can be used for sowing or reasonable storage. if properly managed, a string of red flowers will bloom at the top of the branches, which is worth looking forward to.
