What are the cultivation methods of flowers?
The network introduces the cultivation methods of flowers and the introduction of common flower cultivation techniques in the field of green plants and flowers. Next, the editor of this site will introduce to you.
The sowing time should be determined based on the characteristics of the flowers themselves, market needs, local climatic conditions, and seedling raising conditions.
Spring sowing flowers. Annual herbs, most perennial flowers, and woody flowers are suitable for spring sowing. In the northern regions, sowing is usually done from late March to mid-April.
Autumn sowing flowers. Flowers that bloom the following year and some woody flowers are suitable for autumn sowing. In the north, sowing is often done from late August to early September. In the Changchun area, biennial flowers need to be protected from the cold in winter or cultivated as annuals.
Sow immediately after harvesting. Some flower seeds have high water content, a short lifespan, and lose their germination ability easily after losing water, so they should be sown promptly after harvesting. For example, calamus, Hippeastrum, kaffir lily, camellia, and Begonia semperflorens.
Staggered sowing. Some warm-loving flowers with short growing periods can be sown in installments according to needs.
Year-round sowing. Greenhouse flowers can be sown in the greenhouse all year round according to needs.
Ensuring the normal growth of flowers requires disinfecting the sowing soil.
Sun exposure. In the summer, spread the culture soil thinly on a clean cement floor and turn it over 1-2 times a day, allowing it to be exposed to the strong sun for 15-20 days, which has a certain disinfecting effect.
Steam disinfection. This is the use of the heat released by the steam for disinfection. This method is the most effective and reliable. Keeping the temperature at 100 degrees Celsius for 10 minutes can achieve the purpose of disinfection. A small amount of soil can also be placed in a steamer for 2 hours to achieve the same purpose. A pressure cooker can also be used for disinfection.
Chemical disinfection. Commonly used chemicals include formalin, methyl bromide, and trichloronitromethane. The method of disinfection is to dilute the chemical with water (concentration according to the instructions on the bottle), spray it on the soil, mix it evenly, then cover the soil with plastic film, remove the film after several days, spread the soil, and turn it over multiple times, so that the chemical gas can fully volatilize within about 1 week without leaving any residue.
Manual germination before sowing is very important. Germination refers to breaking seed dormancy through artificial methods to make them germinate. Germination can shorten the seedling emergence period, make seedlings emerge uniformly, and improve the quality of flower seedlings.
Soaking seeds for germination. For seeds with short dormancy and easy germination, soak them in warm water and sow directly without germination; while some flower seeds are soaked in warm water at 30-40°C before sowing, then placed in a constant temperature incubator for germination, and sown immediately after the seeds start to germinate.
Low-temperature treatment. Some flower seeds need to go through a period of low temperature (0-10°C) treatment to promote maturity and break seed embryo dormancy to germinate.
Hormone treatment. Some flower seeds have the characteristic of epicotyl dormancy, and only the young roots can grow in autumn sowing. They must go through a period of low temperature in winter, and the epicotyl can grow out of the soil in spring. If soaked in a solution of 50-100 mg/L of gibberellin for 24 hours, an aerial stem can grow in about 10-15 days.
Physical methods. For seeds with hard seed coats that are not easy to absorb water, manual methods can be used to abrade the seed coat or nick the seed coat to promote germination.
The above is the detailed introduction of the cultivation methods of flowers and the introduction of common flower cultivation techniques. Do you understand now?
