Method for accelerating germination of chrysanthemum seeds

The seeds of chrysanthemum need to be soaked before sowing. First , soak the seeds in warm water at 30~35℃ for 24 hours . Then wash them, take them out and wrap them with several layers of wet cloth, and germinate them in an environment with a temperature of 15~20℃. Remember to rinse the seeds with clean water every day. After 3~4 days, the seeds can be sown after they turn white .

Methods and steps for planting chrysanthemum

Sowing time

Chrysanthemum chrysanthemum is planted mainly in spring and autumn . In the north, spring sowing is from March to April, and autumn sowing is from late July to early September. In the south, it is slightly different, with spring sowing from late February to late March, and autumn sowing from mid-August to early September.

Land preparation and fertilization

Chrysanthemum chrysanthemum has low requirements for soil. Sandy loam with loose soil and good drainage and irrigation is the best. The soil pH should be between 5.5 and 6.8.

Chrysanthemum is a fast-growing vegetable. The base fertilizer is 5 cubic meters of decomposed manure and 35 kilograms of nitrogen, phosphorus and potassium compound fertilizer per mu. Then level the ridges, which are generally 1-1.5 meters wide.

sowing

Chrysanthemum can be broadcast or row-sown. In spring and autumn, open-field planting can be broadcast. First, before sowing, irrigate the soil to create moisture, and evenly broadcast after the water seeps in, and then cover with soil about 1.5 cm.

For row sowing, first dig shallow furrows 1-1.5 cm deep with a row spacing of 8-10 cm. Then sow the seeds in the furrows, cover with soil and water.

Field management

Field management mainly involves watering, topdressing, pest and disease control, etc. After sowing, the ground should be kept moist to facilitate germination, and water should be applied when the seedlings are 3 cm tall. Water 2-3 times during the growth period, and pay attention to prevent excessive humidity.

When the chrysanthemum seedlings grow to 10-12cm, topdressing is carried out, and topdressing is carried out after each harvest. During the growth period, quick-acting nitrogen fertilizer is applied 1-2 times with water, and about 15-20 kg of urea is used per mu.

Pest Control

The main diseases of chrysanthemum include damping-off, leaf blight, downy mildew, anthracnose, virus diseases, etc. The insect pests include aphids, whiteflies, cabbage worms, diamondback moths, and armyworms, etc. In the prevention and control of diseases and insect pests, we must adhere to the principle of "prevention first, comprehensive prevention and control".

Harvest

When the chrysanthemum grows to about 20cm and has 12-13 true leaves, it can be harvested. Be careful not to harvest too late, as this will affect the quality. When harvesting, use a sharp knife to leave 2-3 leaves at the base of the stem, then remove the yellow leaves and tie them into small bundles for sale.
