A string of red sex warm, humid and sunny environment, cold frost fear, avoid dry heat, the optimum growth temperature of 20 ~ 30 °C, 10 °C leaves yellow off, higher than 30 °C, leaves and flowers become smaller . Requires loose, fertile, well-drained soil. First, reproduce A string of red is a good material for the layout of festive flower beds. When mass production is used, sowing is used for breeding. The technical points are as follows. 1. Sowing period It takes about 4 months from sowing to flowering, and a string of reds can be cultivated for an annual period under protected ground conditions. The sowing time depends on the date of flowering. The time spent and sowing time are now listed in the table below. 2. Seed processing The seeds were soaked in warm water at 30°C for 6 hours, then wrapped in a cloth bag containing sand and hand-washed. Wash the surface of the mucus, washed and wrapped in wet Brie, placed in the environment of 20 ~ 25 °C germination, washed with water once a day, about 6 to 7 days of seed germination, you can sow. If it does not take 15 days to germinate. 3. Sowing rate and method A bunch of red seeds weigh 3.6 grams, 1 square meter seedbed sowing rate of 15 to 20 grams. When planting, first impregnate Yangshuo (or seedbed), mix the seeds with 4 times fine sand evenly on the seedlings, cover the soil 1cm, do not over-thick. If sowing in early spring, the ground temperature is low, Yangshuo must be covered with plastic film and straw to keep warm. Generally, seedlings can emerge one week after planting, and often keep the seedbed moist. Second, management 1. Transplanting A string of red seedlings grew extremely slowly, with a cotyledon period of 10 to 15 days. When true leaves grow to 4 to 5 pieces, seedlings can be transplanted. The transplanted bed soil should be full of cooked organic fertilizer. Deeply turn 20 centimeters, shoot flat, plant 10 centimeters and 10 centimeters, and then plant water. After that, pay attention to the cultivator loose soil, until the seedlings grow up, and then planted in the garden or basin as needed. 2. Topping It is very important to take heart in a timely manner, otherwise there will be long stems, thin stems and few flowers. When the 4 to 6 true leaves of the seedlings were taken, the first topping was performed. When 8 to 10 true leaves are picked up for the 2nd time, the growth is considered as a condition, and the heart is picked one at a time. It is advisable to leave 1-2 knots each time. 3. Shu Lei Take the bud shaping can artificially control the flowering period. The inflorescences are terminal and at a temperature of 20 to 25°C, budding and flowering can take place 25 days after budding. According to this rule, if it is required to bloom on August 1, you can pick buds before July 5. If you want to bloom on National Day, you can pick buds before September 5. 4. top dressing A bunch of red inflorescences are numerous and the flowering period is long. The requirements for phosphorus and potassium fertilizers are high during the growth period. It is better to spray 0.5% potassium dihydrogen phosphate solution once every 10 days.
