Calceolaria generally uses the sowing method to propagate, and the ramet method can also be used when seeds are scarce. Sowing should be carried out when the weather turns cold after high temperature, that is, August-September, because seedlings are easy to collapse and rot at high temperature. Mix semi-sand with humus soil or peat soil, sieve and disinfect, put it in a shallow basin, and sow with water by soaking basin method.

Calceolaria's seeds have fine and coarse powders. When sowing, it is best to fold the thick paper into a triangular funnel, put the seeds in it, and then hold the lower part of the funnel with your right hand so that the seeds fall evenly into the sowing basin. Don't be too dense, or the seedlings will grow very thin after emergence. To cover the soil, you only need to cover it with a thin layer of fine soil with a fine screen (it doesn't matter if you don't cover the soil).

Cover the flowerpot with glass after sowing to keep the humidity. Before emergence, it should be placed in a cool place, and the temperature should be kept at about 20℃, and the seedlings can emerge in about 7 ~ 10 days. After emergence, remove the glass sheet and interplant the seedlings, so that the seedlings gradually receive sunlight, and the temperature will be reduced to about 65438 05℃.

When the seedlings have 2 true leaves, they can be transplanted, and when 4-6 true leaves grow, they can be planted in pots alone. 2 parts humus soil, manure 1 part, sand 1 part and 6 parts garden soil were used as culture soil, and the pH value was 6.5. 1 1 By 65438+February, it can be planted in large pots.

cultivation techniques

1, ventilation and shade: calceolaria likes to be cool, and the suitable growth temperature is about 10℃. If the stems and leaves are lush during the growing period, and the humidity of the basin soil is too high and stuffy, the stems of the plants will rot. In order to reduce the temperature, shading measures are often taken at noon to create a ventilated and cool environment. Especially when the seeds mature in May-June after flowering in spring, ventilation and shade should be done at noon, which is beneficial to the development and maturity of the seeds.

2. Water and fertilize: calceolaria likes warm and humid environment, but it is best to avoid too wet soil and too much watering when flowering. Generally, water is only used when the soil is dry. If you are in a greenhouse, you'd better spray water frequently to increase the air humidity. Watering can't directly wash plants. If water accumulates on leaves and buds, it will easily cause rot.

In the growing season before flowering, the decomposed cake fertilizer and water are applied once every 10 day (diluted 10 times), and the phosphorus-based fertilizer is supplemented at the early flowering stage. Fertilizer and water should not pollute leaves to avoid rotting hearts and leaves.

Extended data

It is a perennial herbaceous flower and belongs to a plant. The leaves are opposite, the inflorescence is drooping, and the flowers are shaped like pouches, hence the name Pouch Peony. It blooms in April every year, pink and full of branches, so lovely. ?

Boiled peony is cold-resistant, semi-cloudy and adaptable. Planting in a place with scattered sunlight and good air circulation grows well. In an environment with poor ventilation caused by sun exposure, peony with weak growth is a fleshy root, which is slightly drought-resistant and afraid of long-term water accumulation. Native to northern China, but also distributed in Japan, Russia and Siberia.
