Cultivation techniques of Pogostemon cablin
1, temperature management
When the air temperature is kept at 20~25℃, the emergence time is 10~ 15 days. Uncover the film when the emergence rate reaches 70%, and the suitable growth temperature is 18~25℃. When the spring-sown Pogostemon cablin seedlings were 65438±02cm high and the main stem had five pairs of leaves, the axils of the basal leaves began to branch.
Step 2 apply fertilizer
It is best to apply "full fertilizer" (including nitrogen, phosphorus and potassium) such as human and animal manure and oil cake. For the first topdressing, the water-soluble fertilizer Haihewei should be selected after loosening the soil with a height of 3cm, watered after fertilization, and no topdressing is needed after ridge sealing. Water in time in dry season, protect seedlings against drought, and drain ditches in rainy season to prevent plants from rotting roots caused by accumulated water.
