(1) Fractional propagation: Ranunculus ternatus is mainly characterized by fractional propagation. 65438+ 10 September-June, dig out the root system of Ranunculus ternatus from the soil, shake off the soil on it, and dry it in the shade for 1-2 days. Then, open the root tuber with both hands along the natural potential of the root neck and replant it. Disinfect the roots with formalin or other fungicides before planting.

(2) Seed propagation: The sowing date is generally autumn, because seeds usually do not germinate or germinate slowly at normal temperature (above 20℃). Artificial low-temperature germination should be carried out before sowing, that is, seeds can germinate after soaking at 7-8℃ for about 20 days. After the seeds germinate, the soil must be kept moist. When 2-5 true leaves appear, the seedlings can be planted separately, and then gradually moved into small flowerpots for culture with the growth of seedling age. No chemical fertilizer or a small amount of organic liquid fertilizer can be applied at seedling stage, and flowers can bloom in the second year after maintenance 1 year.

Planting:

Suitable for potted Ranunculus. Sufficient base fertilizer should be applied when planting. Potted soil can be made of 2 parts of garden soil, 1 part of humus soil and 1 part of manure. The planting of tuberous roots should be carried out in the first half of September, if it is too late, it will be unfavorable to plant growth and affect the flowering in the next spring; It's too early, because the temperature is high, and the root is easy to rot. Sowing seedlings are planted in pots when they grow three real leaves.

Fertilization:

After survival, apply thin fertilizer 1 time every week; Apply pancakes and fat water 2-3 times before flowering.

Temperature, light:

In winter, it should be placed in the leeward or in a plastic greenhouse, which can safely overwinter and is more conducive to growth. After the temperature rises in spring, it enters the vigorous growth stage. At this time, it is necessary to strengthen the management of fertilizer and water, and it can bloom from March to May.

Pest control:

If there is liriomyza sativae in the growing period, it can be controlled with 40% omethoate emulsion and 1000 times water.

Plastic decoration:

In the early stage of budding, 3-5 robust buds are selected for each plant, and the rest are removed. At this point, the basin soil should be slightly dry. If there is no need to leave seeds after flowering, the residual flowers should be cut off in time and topdressing with 1-2 times liquid fertilizer.
