The flowers are beautiful in shape, unique in fragrance, people love it, and regret that it can not make people enjoy their eyes. In many years of practice, after many trials, it can make a sudden appearance of a common appearance. The method is: 1. Grafting. The genus Cactus is a genus of cactus and is a multi-flesh job. Its sisters of the same family make the arrow lotus also belong to the cactus family, which is a genus of flowers and can be grafted. The specific approach is to select the two-year-old, strong arrowroot lotus as the rootstock from April to May, cut it between 6cm and 12cm, and cut a 5cm long mouth with a knife in the direction of the flat along the cut edge. Select the vigorously grown, moderately-sized flowering stems that are inserted in the knife's mouth. The treated plants were kept in a cool place and the soil moisture was maintained at 30%-45%. Appropriately chase phosphate fertilizer and potash fertilizer (pot diameter 15 cm-20 cm can be buried 5 grams -10 grams of potassium dihydrogen phosphate). After 15 days to 20 days, the grafted alfalfa can survive, and it can be called an arrow. Can be opened three or four times a year. They are in early July, mid-August, and mid-September. Open once in mid-October. Most flowering time is between 5 am and 7 am, and each flower can be in bloom for 3 days to 5 days. The lotus flower is reduced by half the time compared to the arrow, 14 to 16 times more than the flowering period, which changes the short-lived nature. The diameter of the flower can reach 12 cm - 15 cm, which is 3 times larger than that of thistle flower. Second, light. Illumination is the main factor affecting the flowering of plants. Changes in light can cause changes in the physiological properties of thistle flower, making it possible to bloom in daylight. Because the flowers are produced in the southern part of the Americas and Mexico, the temperature changes greatly, and the sunshine is hot during the day. Evening flowering at night can avoid hot sun exposure and short flowering time. It can greatly reduce the evaporation of water and slowly form habits, inherited from generation to generation. To change this habit, use the following methods: 1. Extend the lighting time. In the case of avoiding the sun exposure, the time of daylight is about 10 hours. In the evening, it can be continued for three or four hours under electric light to change the flowering time. 2. Change the lighting time. When the flowers are sitting on buds, they are placed in the dark, windless place during the day. At 7 o'clock in the evening, the light is applied to the middle of the night at 3 o'clock in the evening. After 14 days to 16 days of continuous treatment, the flowers can bloom during the day. 3. Overwintering habits. During the wintering period, the alfalfa is placed in dark light, kept at a temperature of 10°C-15°C at room temperature and 30%-40% wet soil. Do not be too dry during the wintering season. Do not be too wet. During flowering, the buds of the pregnant buds were selected to be shaded with black plastic bags. At 7 o'clock in the evening, 20 watt lamps or 40-60 degrees bulbs were used to illuminate the next morning and then they were trapped in plastic bags. This treatment until the flower blooming. After this treatment, the flowers can bloom during the day and the flowering period can reach 8 hours to 16 hours. The hybrids were beautiful in color and were originally milky white. After crossing, they were pale yellow or light yellow reddish flowers. Occasionally, flowers that turned red. If you want to make a speech, you can use these measures.
