A little knowledge of daffodils

Requirements of daffodils on environmental conditions

1. Daffodils like a warm and humid climate, especially in places where there is no cold in winter, no heat in summer, and rainy in spring.

two。 Like water and fertilizer, require loose, rich in organic matter and sufficient water neutral or slightly acidic loam, but also drought and barren.

3. Daffodils like sunshine and can withstand semi-overcast.

4. There should be plenty of water in the flowering period.

5. Narcissus is a short-day plant that can blossom in 10 hours of light every day.

6. Different environmental conditions are needed in different stages of daffodil growth and development.

7. Narcissus likes cool climate during its growing period, the suitable temperature is 10-20 degrees Celsius, and it can withstand 0 degrees Celsius.

8. In the later stage, the temperature is 20-25 degrees Celsius and the humidity is 70-80%, which is the most suitable for bulb expansion.

9. Daffodils have higher requirements for water than flowers, and water supply should be ensured in the period of vigorous growth and development. It should be fully dried in the later stage of growth, otherwise it will affect the bud differentiation.

10. The flower bud differentiation of Narcissus takes place during the high temperature dormancy period in summer. No flower bud is formed from field growth to harvest, and flower bud differentiation begins after a period of time after harvest.

11. Flower bud bolting should be at a lower temperature and 9 degrees Celsius.

twelve。 Like the sunny environment, lack of light growth is weak, is not conducive to the production and accumulation of nutrients.
