Narcissus, also known as Lingbo fairy, is different from many flowers. It has the growth characteristics of autumn growth, winter flowering and summer dormancy. In general, it blooms before and after the Spring Festival. If it is early, it will open in January. If it is properly maintained, the flowering period can be maintained until March.
Narcissus is water fed, which needs to be changed once a day, and then every 2-3 days. After the flower bud is formed, it can be changed once a week. Its normal growth temperature is 10-15 ℃, and it can bloom after 45-50 days of normal water culture, with a flowering period of more than one month. If there is bad weather before and after flowering, the temperature fluctuates from high to low, and the light is insufficient, human intervention is needed to control the room temperature and supplement the light with fluorescent lamp to promote flowering.
According to the observation, Narcissus likes cold and is afraid of heat, and the suitable temperature is 10 ~ 15 ℃. When the room temperature is above 23 ℃, the flowering period is one week; when the temperature is 15-20 ℃, the flowering period is about 10 days; when the temperature is 8-12 ℃, the flowering period can be extended by 15-20 days, so as long as there is a certain low temperature, the flowering period of Narcissus can be extended.
When one or two buds of Narcissus open, you can take them out and put them in the refrigerator for storage. After a few days, you can take them out and put them in the flowerpot for maintenance, and they can bloom normally. Or cut the flower stem, put it in a water cup, put it in the refrigerator, keep the temperature at about 1-3 ℃, put it for 2-3 weeks, take it out and put it in the vase, it will continue to bloom.
In addition, if you want to prolong the flowering period of Narcissus, you can add a small amount of aspirin tablets (1 /4 of which is good) to the flower pot of Narcissus, which can prolong the flowering period and delay the withering of flowers.
The quality of the ball is not good. The ball you buy may not be the same year's ball or the big ball that can bloom. This kind of seed ball needs to be cultured for several years before it can blossom.
It is improper to keep water in time. Generally, Narcissus starts to grow after frost, and it is in dormancy period before frost (the whole summer is in dormancy period). If the bulbs are raised in water before frost or after Qingming, and they can not grow normally, dumb flowers will appear.
Improper maintenance. The indoor temperature is too high, the sunlight is insufficient, the environment is dry, the water change is not frequent, even when the water change hurts the seed ball, it will affect the flowering.
Choose high quality seed ball with more than three years. In the process of water conservation, it is better to choose rainwater or pond water, or place tap water for a period of time. Ensure sufficient light, no less than 6 hours a day; ensure good ventilation, and keep the temperature at 12-15 ℃. When the weather is dry, spray water on the plants every day.
