Culture methods of Chrysanthemum

Soil

Chrysanthemum likes sandy soil with loose soil and good water retention capacity. The pH of the soil is preferably between 5.5 and 7. However, the chrysanthemum is very adaptable to the soil and belongs to the flowers that are easy to raise.

Light

Chrysanthemum is a kind of short sunshine flower. It only needs to receive 14 hours of light a day during the nutrition period, and at other times it should be kept indoors to avoid summer sun exposure to prevent petals from being burned.

Temperature

The suitable temperature for chrysanthemum growth is about 21 degrees. It is resistant to low temperature, can bear the low temperature of minus 5 degrees in winter, but can not bear high temperature, so we need proper shade treatment.

There are so many effects and functions of chrysanthemums. Flower friends raise a pot at home as soon as possible. If you have any questions, you are welcome to leave a message and ask!

Cultivation methods of chrysanthemum soil

The pot soil for planting chrysanthemum had better choose the sandy soil with loose soil, fertile soil and good water retention capacity. And the chrysanthemum has a strong ability to adapt to the acidity and alkalinity of the soil, so we can choose the soil with PH value between 5.5 and 7.

Light

Chrysanthemums are shade-tolerant, do not like light, and belong to short-sunshine flowers. If it receives light for a long time every day, it is difficult for its stems and leaves to blossom, and it can sprout and blossom only when the light time is short. But it should be noted that it needs 14 hours of light a day during its vegetative period and 12 hours of sunshine a day during flower bud differentiation.

Temperature

The most suitable temperature for chrysanthemum growth is 21 degrees. And ornamental chrysanthemum is very cold-resistant and low-temperature, can withstand the low temperature of minus 5 degrees, but not resistant to heat, the temperature will grow slowly when the temperature is more than 32 degrees, so it can be moved to indoor breeding in the hot summer.

Fertilizer application

Chrysanthemums love nitrogen fertilizer and should apply thin fertilizer frequently when applying fertilizer. However, in the bud period, we should pay attention to stop nitrogen fertilizer, apply potash fertilizer, and keep it once a week.

After learning how to cultivate chrysanthemums, the editor will tell you a little trick that can help your chrysanthemums grow more exuberant.

Propagation methods of Chrysanthemum morifolium

Chrysanthemum is generally propagated by cutting, ramet, grafting and tissue culture. One of the most commonly used is the cutting method, and we describe the breeding methods one by one:

The main results are as follows: (1) Cuttage can be divided into bud cutting, tender branch cutting and leaf bud cutting. Bud cutting, cutting plant foot buds in autumn and winter. The standard of bud selection is far away from the plant and the bud head is plump. Remove the lower leaves, according to the plant spacing of 3-4 cm, row spacing of 4-5 cm, inserted in the greenhouse or greenhouse flowerpot or bed, keep 7-8 ℃ room temperature, planted outside after spring warm.

This method is the most widely used, more than 4-5 months cuttage, cutting 8-10 cm as cuttings, at the temperature of 18-21 ℃, about 3 weeks to root, about 4 weeks can be planted. Insert the bed in the open field, the medium should be plain sand, and the bed should be shaded. Full light spray plug bed without shade. Leaf bud cutting, cutting a leaf with axillary bud from the branch, this method is only used to breed rare varieties.

(2) the ramet is usually dug up before and after the Qingming Festival, separated according to the natural shape of the root, and planted in the basin.

(3) in order to make chrysanthemum grow strongly, it can be used to make "Shixiang brocade" or Dali chrysanthemum. Artemisia annua or Artemisia annua can be used as rootstock for grafting. Artemisia seed in late autumn, sowed in greenhouse in winter, or raised in hotbed in March, moved to pot or planted in late April when the seedling height was 3mur4cm, and spliced in sunny day from May to June.

(4) tissue culture uses tissue culture technology to propagate chrysanthemum, which has the advantages of rapid propagation, large number of seedlings, detoxification and keeping variety characteristics. The basic medium was MS, with appropriate amount of plant hormone, pH5.8. Use the stem tip, tender stem or bud of chrysanthemum as explants, cut into 0.5 cm segments and inoculate. The temperature of the culture room was 25 ℃ + 1 ℃. The light intensity is 3000mur4000 lux for 8 hours a day. After 1Mel culture for 2 months, the plantlets could be induced.
