Introduction to the characteristics of a bunch of safflower
Salvia splendens is a perennial herb with opposite leaves on the stem. The leaves are green, oval or triangular with serrated edges. The flowers are red. Of course, there are mutations now. Flowers are white or purple, but red is more common and dense. A bunch of red plants can be divided into small and medium-sized plants, the small ones are 20 to 40 cm, and the medium ones are generally less than 100 cm. A bunch of red fruits are small nuts, oval, with tiny black seeds in them.
Propagation method of a bunch of safflower-sowing method
Sowing method: In addition to the self-sowing propagation of a bunch of red seeds, there are two methods of sowing or inserting propagation, and sowing is generally more common. Spring is generally suitable for sowing.
A bunch of red flowers met late. If you sow in spring, the flowering period will be in autumn. If you want to bloom early or harvest seeds, you should sow in a greenhouse or hotbed when it is not too cold after the New Year. Apply a small amount of base fertilizer to the seedbed, level the bed surface and water it. After the water permeates, you can sow. After sowing, the seeds are covered with a thin layer of fine soil, and the seeds germinate 8~ 10 days after sowing. Cutting method: Cutting method is generally suitable for breeding a bunch of safflower in March-May or September-65438+1October. Cutting is a tender branch with full tissue, and the terminal bud needs to be removed before cutting to facilitate rooting. In summer, due to the high temperature and dry climate, attention should be paid to shading, cooling and spraying water to keep the soil moist so as to facilitate cuttings to take root. /kloc-Roots will grow in about 0/5 days and can be transplanted. Cutting is a faster and simpler propagation method than sowing.
Matters needing attention in the cultivation of string red wine
When a bunch of safflower grows 3-4 pairs of true leaves from sowing to germination, the stem tip should be removed and each seedling with at least 4 lateral branches should be transplanted into a flowerpot. When it is moved to the flower bed, it is appropriate to have flowers at the end of the branches. Generally, a flower bed is planted with a bunch of red flowers, with a spacing of about 40 cm.
Soil: Raising a bunch of red grapes requires higher soil.
Because a bunch of red sage is suitable for growing in weak acid soil, it is required to use sandy weak acid soil with loose soil, fertile soil and good drainage. Lighting: A bunch of safflower is a plant that likes sunshine and is also tolerant to semi-shade, so indoor planting should be placed in a place with sufficient lighting conditions.
Temperature: beam red has poor cold tolerance, and the suitable growth temperature is about 23 degrees Celsius. If the temperature is lower than 15℃, a bunch of safflower will stop growing. If the temperature is below 5℃, their leaves will turn yellow and fall off.
Fertilization: During the growth period of a bunch of red flowers, we can apply phosphorus-containing liquid fertilizer 1 2 times, which can make a bunch of red flowers flourish and have a magnificent appearance at flowering stage.
Watering: A bouquet of red flowers should not be watered too much. Too much water will cause the leaves to turn yellow, even cause the leaves to fall off, and also cause the plants to be big and have few flowers.
Summary: The above is the cultivation method of a bunch of safflower introduced to you. In the growth period of a bunch of safflower, we should always pay attention to the growth dynamics of a bunch of safflower, always pay attention to pinching and shaping, control the height and branches of the plant, make a bunch of safflower grow fat and tidy, and ensure the beauty of a bunch of safflower.
