The daffodil is also called the horn narcissus. It is the genus Narcissus. Because daffodil is a temperate bulbous flower, it prefers a cool climate. Avoid high temperature and humidity, and the fertility temperature is 10-15 °C. In the south of China, it is not easy to cultivate flowering balls. Every year, bulbs are imported from abroad, and they are flowered after short-term cultivation. After flowering and viewing, they can be discarded. In the next year, they will purchase bulbs. When purchasing the bulb, check whether the bulb is refrigerated. If it is a bulb that has not been refrigerated, it should be stored in a refrigerator at 8-10 °C for 40-50 days after being bought back to break its dormancy period. flowering. Many flower friends are very helpless when they buy the ball. I don’t know if it is really imported. The refrigerated daffodil bulbs are planted 50 days before the Spring Festival. The cultivated soil is preferably organic-rich micro-acid fertile sandy loam, organic fertilizer is pre-embedded in the soil, or peat is piled up with organic fertilizer. The effect of planting a small amount of river sand is also good. Usually, depending on the size of the planting pot, 3 to 5 kinds of bulbs per pot are used in the form of clumps, and the bulbs must be completely covered with soil. After planting, it is moved to the semi-shade where the sunshine is about 50%. The soil is always kept moist. When the leaf buds extend out of the soil surface, the potted plants are moved to an environment where the sunshine is about 70-80%. During the growth period, it is diluted once with dilute potassium phosphate solution every two weeks, and a small amount of nitrogen fertilizer can also be applied. The growth temperature is 15-20 °C. Different illuminance, humidity and temperature can be used to adjust the flowering period to achieve the purpose of just blooming in the Spring Festival. The breeding of daffodils is usually divided into balls, and the natural reproduction rate can reach 4-5 times. Usually done in the fall. When breeding, the small bulbs that are divided on both sides of the mother ball are planted under the arm and planted separately. In order to accelerate the reproduction, the mother ball should be planted shallow and not deep. Too deep, fewer sub-balls occur. In addition, the sliced ​​bulbs were cut from the stem to the top with a slice of 3-4 knives, and the depth was about half of the bulb. After cutting, the bulbs were placed in clean dry sand to produce callus, which was then placed in a breeding box at 21 °C. When the temperature rises to 30 ° C and the relative humidity is 85%, most of the sub-balls will be produced in about 3 months, and the sub-balls can be removed. The bulbs need to be planted in 3-4 years to become flowering bulbs. The sowing and breeding of the daffodils was carried out in mid-September, and the sowing soil was mixed with humus soil, peat soil and coarse sand, and used for seeding after disinfection. After sowing, fine management, germination of small plants in early spring, leaves and roots withered in early summer, forming small bulbs. Seeding small bulbs should be cultivated for 4-5 years before flowering.
