Primrose seed collection matters
Primroses seed from May to June. During this period, pay attention to ventilation and dehumidification. Because the maturity period of seeds is different, it is necessary to mature at the same time for harvesting. In addition, the collected seeds cannot be exposed to the sun, but need to be placed in a cool place and dried, so as not to reduce the germination rate of seeds p>
Primula sowing and propagation
Sowing time
Primroses are mainly propagated by sowing. The sowing date should be determined according to the needs of flowering. Generally, they can bloom about 6 months after sowing. The service life of primrose seeds is relatively short, so it is best to sow immediately after seed collection, or store them in a low-temperature and dry place p>
Sowing temperature
The most suitable temperature is 15-21 ℃, which must not exceed 25 ℃, otherwise it will not germinate p>
Sowing basin soil
When sowing, it is best to use a shallow basin, select loose and well drained fine soil, and use fine rotten leaf soil and garden soil as basin soil p>
Sowing method
Level the soil in the basin, then mix the seeds with 4 times of fine sand and sow them evenly in the basin. Because the seeds are relatively small, it is necessary to gently compact the soil surface with smooth wooden board without covering the soil, which is conducive to the water absorption and rooting of seeds p>
Seeding management
Watering is required after sowing. The basin immersion method is adopted. Put the whole basin into the pool to soak water, and let the water slowly seep upward from the small hole of the basin to the basin surface until the topsoil is soaked and then take it out. Then cover the glass, which is conducive to moisturizing. Put it in the semi shade for about 1-2 weeks, and it can germinate. Remember to remove the glass, and then move it to a place with light< span>
