After eating colchicine by mistake, vomiting, abdominal pain, abdominal distension, weak pulse, cold sweat, diarrhea, irregular breathing, elevated body temperature, lethargy, collapse, etc. In severe cases, convulsions and paralysis can lead to death.
Narcissus cultivation methods include soil culture, sand culture, water culture and sculpture modeling. The cultivation technique is not high, as long as the temperature is kept at about 65438 05℃, the flowers can bloom after 25 ~ 30 days of cultivation with sufficient sunlight, frequent watering and frequent change of water. However, we should pay attention to the following points: (1) The temperature should not exceed 25℃, otherwise it will stop growing and enter dormancy, resulting in yellowing and shrinkage of buds; (2) Sufficient sunshine, otherwise the leaves will grow into garlic leaves; (3) Use clean water, otherwise the roots will be polluted and rot due to water deterioration.
Narcissus has special growth characteristics, and the date of flowering can be decided by people themselves. If it is required to bloom during the Spring Festival, bulbs (narcissus heads) can be planted in pots about 20 ~ 30 days before the Spring Festival, and then start to grow until they bloom. Here are some breeding methods:
Soil planting
Soil planted with soil needs loose humus. Before planting, peel off the dry bulbs outside the narcissus head and scrape off the old roots, and add humus soil at the edge of the pot 3 cm. Shake the flowerpot with both hands to make the humus soil dense, then put the bulbs of narcissus into the flowerpot, add about 1cm of soil, then water, then put the flowerpot in the shade, and after the bulbs take root five days later, put the flowerpot in a sunny place for cultivation. When planting soil, we should pay attention to the wet and dry, that is, we should water the soil before it is dry until the bottom of the basin leaks, and the watering time should be chosen in the morning and evening, otherwise it will destroy the growth of the root system.
Shaji culture
It is best to plant sand with clean fine sand, and the basin also requires a well-ventilated soil basin. Before planting, put the sand into the basin and put it at the edge of the basin 3 cm. Then put the narcissus head stripped of its old stems and roots into a flowerpot filled with fine sand, and add about 1cm of sand to make the stem under the narcissus head buried in about 1cm of sand. Then water it and put it in the shade. Put it in a sunny place after 5 days until it blooms. Planting narcissus heads with sand should be watered every day. Not watering in time will cause water shortage and affect the growth of flower roots. Watering should also be arranged in the morning and evening.
Hydroponics
Before hydroponics, peel off the old stems and roots, then put them into the cultured daffodil basin, add water to the bulbs about 1 cm below the daffodil head, and put them in the shade and in the sunny place until the bulbs grow roots. It is best to change the water for hydroponic narcissus every day, on the one hand, to prevent the root rot caused by water quality deterioration and pollution, on the other hand, to change the water every day, and the clean roots that grow out of the water are also white and beautiful.
Narcissus tazetta. var。 Taxus China. : Also known as Chinese narcissus, it is a variety of daffodil. It is a perennial herb of Amaryllidaceae. Narcissus leaves are extracted from the green and white tubular sheath at the top of the bulb and then from the leaves. Generally, each bulb can take out 1-2 stems, and many bulbs can reach 8- 1 1 branches, which are umbels. There are six petals, and the ends of the petals are yellow. There is a bowl-shaped protective cover outside the stamen. Bulbs are ovoid to wide ovoid and covered with a brown film. The leaves are long and narrow, and the back of the capsule is cracked. Flowers bloom in spring.
Narcissus likes warmth, humidity and good drainage. It has been cultivated in China for over 1000 years. It is a traditional ornamental flower and one of the top ten famous flowers in China.

Flowers that bloom from winter to spring. Similar oxalis plants. There are nearly ten thousand varieties.
The original species of Chinese narcissus was introduced from Italy in the Tang Dynasty. It is a variety of narcissus tazetta l. It has been cultivated in China for more than 1000 years. After thousands of years of cultivation, it has become one of the best daffodils in the world and one of the top ten traditional famous flowers in China.
Because the bulb looks like onion and garlic, it was called "elegant garlic" in the Six Dynasties and "heavenly onion" in the Song Dynasty. After that, people gave her many smart and beautiful names, such as Golden Lantern, Yintai, Lillian, Yake, actress and so on. Narcissus was paid attention to and loved by people as early as the Song Dynasty. During the Song Dynasty, a Fujian-born Beijing official retired to his hometown. When he returned to his hometown in Zhangzhou by boat, he saw a kind of aquatic plants with fragrant small white flowers growing by the river, so he asked someone to collect some and take them back for cultivation.
According to the genealogy of Zhang family in Caiban Township; During the Jingtai period of the Ming Dynasty, their ancestor Zhang Guanghui studied in Kyoto. One winter, he asked for leave and returned to his hometown. He sailed through Jishui, Jiangxi Province, and found green leaves, yellow and white flowers and fragrant wildflowers on the water near the shore, so he picked them and planted them in Caiban to make them grow into new flowers. According to the Records of Zhangzhou Prefecture, when Zheng He went to Nanyang in the early Ming Dynasty, Zhangzhou narcissus had been shipped abroad as a famous flower. [2]
On June 9, 2006, Zhang Bingchun, a citizen of Lianyungang, Jiangsu, China, cultivated daffodils with different colors, such as red, yellow, blue and green, so it is also called colored daffodils.
