The suitable temperature for germination of Yufan seeds is about 20 ℃. Generally, the temperature shall not be lower than 10 ℃, and it is better not to exceed 25 ℃. And the temperature difference between day and night is about 8-10 ℃.
Generally, you can choose a loose and well permeable matrix with a particle diameter of less than 3mm and a thickness of about 5cm and 6cm. For example, you can choose to mix red jade soil, deer swamp soil, rice husk ash and high-quality peat according to 4:4:1:1, or vermiculite, red jade soil, perlite, chaff charcoal and peat according to 5:5:5:3:2, and finally add some bactericides to the base fertilizer.
Put the dry soil into the basin, pave the soil surface, and then carry out on-demand sowing or sowing. Cover a thin layer of soil, which is about the same thickness as the seed. Then spray the fungicide solution such as Carbendazim and potassium permanganate for disinfection, place it for one night, and then start the whole management. When it's full of water vapor, open it for ventilation. Pay attention to avoid direct sunlight, or the seeds will be cooked in the soil due to rapid warming. Keep the substrate moist. Spray fungicide once a week, pay attention to the variety of fungicide to be used alternately.
After sowing, the time of germination varies according to the specific situation, most of them can germinate after 10-20 days. After germination, it is still dry and wet. One month later, it will increase air permeability. After two months, it will not need to be fed. Pay attention to the appropriate light and temperature, generally 60% shading is appropriate, control not to sun the seedlings red. A small amount of liquid fertilizer can be applied at two months to provide certain nutrients. At the same time, pay attention to heat preservation, the general temperature can not be lower than 5 ℃.
