Sowing temperature of jade fan
The suitable temperature for seed germination of Yufan is about 20 ℃. Generally, the temperature shall not be lower than 10 ℃, preferably no more than 25 ℃. And there needs to be a temperature difference between day and night of about 8-10 ℃ p>
Planting medium of jade fan
Generally, the matrix with loose water retention and good air permeability can be selected. The particle diameter should be less than 3mm and the thickness should be about 5 or 6 cm. For example, you can choose to mix akashite soil, Luzhao soil, rice husk ash and high-quality peat according to 4:4:1:1, or vermiculite, akashite soil, perlite, chaff carbon and peat according to the ratio of 5:5:5:3:2, and finally add some fungicides, or add an appropriate amount of base fertilizer p>
Sowing method of jade fan
Put the dry soil into the basin. After paving the soil surface, it can be sown on demand or scattered. It can be covered with a thin layer of soil, which is about the thickness of the seed. Then spray carbendazim, potassium permanganate and other fungicide solutions for disinfection, place them for one night, and then start the whole stuffy management. When it is full of water vapor, open it for ventilation. Pay attention to avoid direct sunlight, otherwise the seeds will be cooked due to rapid heating in the soil. Keep the substrate moist. Spray bactericide once a week, and pay attention to the variety of bactericide to be used alternately p>
Management of Yufan after sowing
After sowing, the time of germination varies according to the specific situation, and most of them can germinate after 10-20 days. Keep it dry and wet after germination, and increase air permeability after a month. After two months, there is no need to keep it stuffy. Pay attention to the appropriate light and temperature. Generally, it is appropriate to block 60% of the light. Control not to redden the seedlings. A small amount of liquid fertilizer can be applied in two months to provide certain nutrients. At the same time, pay attention to thermal insulation, and the general temperature shall not be lower than 5 ℃< span>
