Pogostemon cablin is usually planted in spring and autumn every year, and it is most suitable in March-April and 9-65438+1October. Sandy loam can be selected, and the temperature is controlled at 18 ~ 25 degrees. Usually, nitrogen, phosphorus and potassium fertilizer are mainly added and watered according to the growth situation.

1, temperature:

Generally speaking, the average annual temperature of Pogostemon cablin is around 19 ~ 26 degrees. The suitable temperature for the growth of Pogostemon cablin is 15 ~ 25℃, and the planting temperature should be kept between 20 ~ 25℃ when seedlings emerge.

2, water and fertilizer management:

Fertilization should be combined with watering and intertillage, which is beneficial to the absorption of nutrients, while maintaining the humidity of soil and maintaining the water supply needed for normal life and storage of plants. Finally, when it rains heavily, we should pay attention to timely drainage to prevent water damage.

3. Plant density:

Generally, if sowing in spring, the sowing amount per mu is 500 to 800g, and if sowing in autumn, the sowing amount per mu is 500 to 600g. As can be seen from the above sowing amount, the planting density in autumn will be greater than that in spring. The row spacing of spring sowing is generally between 25 and 30 and 35 cm, and autumn sowing is generally between 30 and 35 cm.
