Du Fu is a well-known flower at home and abroad. It has a long flowering and a long flowering period. It has bright green leaves and is a fine flower that embellish the study, bedroom, living room, and landscaping. Azaleas usually bloom from late February to June. Can they be decorated during the Spring Festival? After many years of practice, the author has proved that he can do it. First of all, we must understand the requirements of the azalea flowering on the external environmental conditions. Rhododendrons usually need to go through low temperature dormancy before they bloom in spring, which requires certain conditions such as temperature, light, moisture, humidity, and nutrients. When the temperature is 13°C-22°C, the soil moisture content is 60%, the humidity is 70%-80%, and the light is more than 4 hours per day. When the proportions of nitrogen, phosphorus, potassium, calcium, magnesium and zinc are suitable, the azaleas bloom large. Bright color and long flowering period; when the temperature is below 5°C, it is in dormant state; when soil moisture content is lower than 30%, flowering time is delayed 4-5 days or even longer than soil moisture content 60%; When the indoor humidity is too dry, the flowers are dry and the petals are not bright. The flowering is 6-8 days later than the normal humidity, and it is about 10 days early. When the light is lacking, the flower color is not bright, and the flowering period is short. In addition, fertilizers have a great influence on the flowering of azaleas. Rhododendron needs nitrogen, phosphorus, and potassium fertilizers, followed by sulfur, magnesium, and iron. According to Du Fu’s above characteristics, the following measures can be taken to promote its flowering during the Spring Festival. 1. Control the appropriate temperature. 40-50 days before the Spring Festival, select the cuckoo varieties (depending on the early, middle and late varieties), cover the whole plants with plastic bags, and tie the lower part with a string on the flower pots and place them on the sunny window sill of the house. on. When the room temperature reaches 8°C-10°C, the temperature inside the plastic bag can maintain 13°C-15°C, generally 4°C-6°C higher than the temperature without bagging. The humidity in the bag is also relatively high and it is not easy to evaporate moisture, which is beneficial to the growth of azaleas. It can also prevent dust pollution and keep the leaves and petals clean. 2. Give light. Place the pot on the sunny window sill, and ensure that the light shines for 3-6 hours every day. If conditions are not met, use a 25-watt bulb or 15-watt fluorescent lamp to make up for it. However, it should be noted that Du Fu has certain requirements for light. If the light is too strong or too long, the normal physiological effects will be misaligned, and metabolism will be hindered, affecting photosynthesis. 3. Keep moisture. The rhododendron pots must be kept moist regularly to ensure that the flowers are bright and colorful. Some people suggested that winter is not watered, or that it is dry and then poured, which is inappropriate. In general, the water content of pots and soils should always be kept between 55% and 65%. With the same age plants, the same size flowerpots, the same management conditions of 3 azaleas for comparison test, potting water content of 55% -65%, 40 days of bagging flowers, flower diameter 9-12 cm, flowering 62 days, flowering rate of 100% (calculated by buds); basin soil water content of 20% -30%, 55 days before bagging flowering, flower diameter 7-8 cm, flowering 40-45 days, flowering rate of 85% - 87%; dried and then watered rhododendron, bagged 60 days before flowering, flower diameter 5-6 cm, flowering 25-30 days, flowering rate of 40% -50%, after flowering plant branches less, and then died. Therefore, it is very important for Du Fu to manage water in due course in the winter. 4. Ensure sufficient fertilizer. Fertilizer is one of the basic conditions for the flowering of azaleas. However, proper amount of fertilization must be applied in order to make the azalea bloom large and beautiful, and the plants are robust, strong and resistant to disease. Rhododendron fertilization should be carried out in September-December and January-April. Fertilizers mainly include soybean cakes, soybeans, peanut cakes, horseshoe pieces, wash rice water, washed fish water, chicken manure, milk sauce, eggs, etc., but they must be brewed and used until fully cooked. The decomposed fertilizer can be dried or diluted with water. Fertilization method: chicken manure after decomposed and dried into powder, sprinkled on the pot topsoil, nutrients with water seepage, the effect is very good. Pots 15-20 cm in diameter can be sprinkled. Other fertilizers are based on the size of the pots and plants. Generally 3-4 years old, azalea, can use 4 pinch bean cake powder (3 fingers for 1 pinch). Rhododendrons should not be big fertilizers and concentrated fertilizers. Generally, a thin liquid fertilizer can be applied to avoid "burning" the plants. If it is found that the tip of the coke is dry, it is mostly due to hypertrophy. Remove the fertilizer immediately or change the soil, and then rinse with plenty of water several times to reduce the amount of fertilizer. In addition, the control of flowering during the Spring Festival should be a good variety. At present, the better varieties are: Qinghan Peony, Zifeng Chaoyang, Babao Hibiscus, Green Peony, Fengming Jin and Sihaibo. These are double-flowered flowers, and their ornamental value and economic value are very high.
