Cultivation method
Narcissus is sunny, warm, requires high air humidity, is not very cold-resistant, and is afraid of hot, sandy soil that needs to be moist and does not accumulate water during the nutrient growth period. Narcissus is different from other perennial herbaceous flowers. It has the characteristics of beginning to grow in autumn, flowering in winter, storing nutrients in spring, and dormancy in summer.
There are two methods of cultivation of narcissus, hydroponics and soil culture.
The hydroponic method is cultured in a shallow basin water immersion method. The narcissus-treated narcissus is placed upright in the narcissus shallow basin, and it is better to add one-third of the bulb to the water. The bulbs can be fixed in quartz pots, pebbles, etc. in the pots.
During the day, the narcissus pots should be placed in a sunny place, moved into the room at night, and the water in the basin should be drained to control the length of the leaves. Add water again the next morning, taking care not to move the bulbs in the direction. When the basin is just above the basin, the narcissus can be changed once a day, and every 2-3 days later, after the flower buds are formed, the water is changed once a week. The narcissus grows well under the environment of 10-15 degrees, and it can bloom in about 45 days, and the flowering period can be maintained for more than a month.
During the narcissus water conservation, special light should be given, and it should be placed in a sunny place during the day and under the light in the evening. This will prevent the narcissus stems from growing and make the narcissus leaves short and wide, strong, and the leaves are dark green and the flowers are fragrant. Water narcissus, generally do not need to apply fertilizer, if conditions, slightly apply some quick-acting phosphate fertilizer during flowering, flowers can be opened better.
The soil culture method is rarely used, that is, the cultivation method of most earthward flowers is used to cultivate the narcissus. In the middle and late October, the large bulbs were planted into the small potted pots with fertile sandy soil, half of which was half exposed, and some fine sand should be placed in front of the scales to facilitate drainage. Place the pot in a well-lit, temperature-friendly room. 4 to 12 ° C is good, the temperature is too low, it is easy to freeze damage, the temperature is too high and the light is insufficient, it is easy to be steep, the plant is weak, the flowering time is short, and the ornamental value is reduced. If the requirements of light and temperature are met in the management, the leaves are large and the flowers are thick and strong so that the flowers can be opened large and the fragrance is long-lasting. Soil narcissus can be used to apply two to three liquid fertilizers before flowering.
Daffodil is not able to breed on its own due to limited climatic conditions. Cultivate narcissus, if there is no pest damage, do not need to spray medicine. In winter, hydroponic narcissus, temperature, light, and water supply are the three elements of whether narcissus can bloom. Narcissus growth requires sufficient sunlight; a suitable temperature is 12 ° C - 15 ° C; clean water.
Use of narcissus
Anti-aging and anti-wrinkle skin
Environmental conditions (ultraviolet rays and pollutants) increase cell division and cause premature aging of cells. Since the number of cell divisions is limited, cells can be kept in a relatively young state by keeping cell capital in an early stage of division. Narcissus bulb extract can slow cell proliferation, prolong the maturity of the cell can make the skin have more mature cells, and it can better resist the damage of external environmental factors. In addition, the narcissus bulb extract can make the skin elastic and firm, improve the wrinkle depth and achieve an anti-wrinkle effect.
Whitening
Dendrobium bulb extract can significantly inhibit the production/release of ET-1, which can completely inhibit IL1a-induced upregulation of ET-1 in normal human keratinocyte culture experiments. Daffodil bulb extracts achieve skin whitening by slowing the proliferation of melanocytes.
Skin moisturizing
Extracted from daffodils to form a natural moisturizing essence, which is integrated into the skin to provide moisture to the skin. It moisturizes the water film on the skin surface, moisturizes the skin from the inside out, improves the lack of water, dull and tired skin, and restores moisture to the skin. Tender slippery
Haircare
The narcissus bulb extract protects the scalp, reduces oil content, and removes dandruff. In addition, it can achieve hair removal indirectly by keeping the hair's hair growing slowly after mechanical hair removal.
In addition, the narcissus bulb extract can also be applied to medical cosmetics, such as psoriasis, eczema, and acne diseases caused by skin and scalp cell proliferation disorders.
