Key points of conservation of azaleas during the Spring Festival

During the Spring Festival every year, it is often the peak season for the flower market, and the Lunar New year flowers are also very popular during the Spring Festival. No matter they are given away or placed in their own home, the Lunar New year flower is a good choice. Azaleas are also common New year flowers, but because azaleas are common varieties and have a short flowering period, we should pay attention to cultivation methods when raising them during the Spring Festival.

Rhododendron

Cuckoo petals are very delicate, afraid of low temperature, especially can not be blown by the wind. Therefore, when carrying the azaleas home, be sure to cover the flowers with windproof and thermal insulation materials. if freezing seriously damages the roots, it will kill the whole plant. Cuckoos in bud are relatively resistant to freezing. In addition, many people do not like the original flowerpots and ask to change them, which is actually very harmful. Because changing pots will cause damage to its roots, it is most likely to freeze at this time. In addition, it is generally necessary to water immediately after changing the basin, and the root can only be restored after 3 Mel's slow root for 5 days. If the root system is damaged too much, it may not be able to recover.

At home, we should pay attention to control the temperature at about 20 ℃ and increase the indoor humidity as much as possible. Some people think that spraying water on flower leaves and flowers can play a humidifying effect, which only works when the flower root system is damaged, but when the root system is intact, it will make the flower bloom faster, so it still depends on the humidifier to increase indoor humidity. Secondly, watering should not be too frequent or exposed to the sun, which will speed up the flowering speed. Because the cuckoo basically completed the "mission" after the end of flowering, and also added fertilizer to promote flowering, there is no need to apply fertilizer.

The cultivation method of azaleas, how to raise azaleas?

With the continuous improvement of material life, people's enjoyment of life is also increasing. As a result, we know more and more about plants, and we will breed a pot to make our life more romantic. I don't know if you have chosen a kind of plant for yourself to cultivate, if not? That's good. Let's take a look at the azaleas, one of the top ten traditional flowers in China.

Introduction to Azalea

Rhododendron, also known as pomegranate, is a deciduous shrub of the rhododendron family. There are about 900 varieties of azaleas in the world, while there are more than 530 varieties in China, which can be said to be the country with the largest distribution of rhododendrons in China. As for this plant, its branches are very many, but very slender. Secondly, the flower bud ovoid of rhododendron is spherical, while the calyx is 5-parted, and its lobes are triangular long ovoid, with a length of 5 mm. The florescence of rhododendron is from April to May, and the fruiting period is from June to August.

Culture method of rhododendron

Under the condition of natural culture, the flowering period of spring rhododendron is from April to May, and that of summer rhododendron is from May to June. No matter what kind of azaleas, the correct method should be taken when cultivating azaleas, and the following are the conditions for cultivating azaleas. 1 Care / temperature: when breeding, it can be removed from the room in April and placed in the leeward and sunny place, and pay attention to shade in summer to avoid the direct light. The second is that the growth temperature is 15 Murray 25 degrees, and the highest temperature is 32 degrees. 2 moisture: water should be watered once after the first cultivation and soil change, so that the roots are in full contact with the soil, which is beneficial to the survival of the roots. In the growth, we should also pay attention to watering, after March, to increase the number of watering, especially in summer, to keep the basin soil moist, and to reduce the watering times in September. 3 soil: it is better to be loose and fertile and rich in humus, while acidic sandy soil is the best. 4 fertilization: reasonable fertilization is the key to cultivating rhododendron. The plant is fine and avoid thick fertilizer. It can be fermented with rice water, pericarp, vegetable leaves and so on.

Matters needing attention in rhododendron culture

When raising azaleas, prune the plants. If you want to control the florescence yourself, move the plants to a 20-degree greenhouse in January or 20 days before the Spring Festival, so you can watch the azaleas during the Spring Festival. Of course, the flower language of the azaleas belongs to you forever, the joy of love and the desire to control. In addition to having ornamental value, it can also be used as medicine, such as anti-inflammation and bacteriostasis, analgesia, antitussive and so on.

Conclusion: the above are the key points of rhododendron planting and the matters needing attention of the plant, and it is worth noting that when breeding, we should also pay attention to the prevention and control of plant diseases and insect pests.

Belgian rhododendron conservation key points Belgian rhododendron culture methods Belgian rhododendron conservation key Belgian rhododendron is a world-famous woody flower. Its plant shape is short and strong, the crown is compact, developed and sturdy, and the roots are numerous. The leaves are thick, thick green and shiny. The florescence is from January to May, and the flowering period can be controlled under greenhouse conditions. Double flower, ruffled,. The shape of crimping, waves, etc. The flower color is very rich, the flower is numerous, the flower diameter is 6-8 centimeters, the biggest reaches 10 centimeters. The suitable temperature for the growth of Belgian rhododendron is 15-30 ℃, the temperature difference between day and night is about 103v, the environmental humidity is 600h, above, the physiological extreme lowest temperature can withstand-3 ℃ low temperature (natural overwintering) and short-term 40CC high temperature, but the long-term temperature is too high or too low, or the temperature difference is too small. Suitable for acidic (pH4.5-6), loose, water-retaining and breathable soil, such as peat, pine needle soil, humus soil, sawn powder, waste mushroom material, red sandy soil, sandy mountain soil, etc., if the acidity is insufficient, it can be adjusted with appropriate amount of ferrous sulfate. The Belgian cuckoo needs 50% Mel 70% shading from late spring to early autumn, and the greenhouse does not block the light in winter and keeps the temperature above 3 ℃ at night. In the south of the Yangtze River, double-layer arch sheds are used to cover; the warm parts of the south can spend the winter with a single layer, and the occasional cold current should still pay attention to prevent frost damage; solar greenhouses and heating greenhouses are often used in the north, and ventilation should be paid attention to in the greenhouse in winter and spring, so that the indoor temperature does not exceed 32 ℃. Belgian rhododendron water management is more important, generally moist, can not be too dry, so as not to affect the normal growth and development. Usually watering requires neutral or acidic surface water. If groundwater is used in the north, it is necessary to reduce salt or acidify. Potted pots can be made of plastic pots, seedling pots and mud pots. Before planting, 1% of the cake fertilizer that has been retted by people can be added to the substrate, or 0.5% of the long-acting slow-release fertilizer with high nitrogen content. Usually topdressing is mainly nitrogen fertilizer (money nitrogen), generally using raw cake or retted dry cake 5 g / l pot (15-20 cm diameter flowerpot) and 0.1% urea solution. During flower bud differentiation, 0.1% urea plus 0.19% potassium dihydrogen phosphate is applied once every 15-20 days. If iron deficiency occurs, 0.2% ferrous sulfate can be used once a week until recovery. Belgian rhododendron plastic surgery is mainly to pick the heart, once every 60-80 days, the new tip is required to be flat, in order to form compact and smooth. If the Yuan and Spring Festival flowering is required, the last time to set the shoot should be in the south of the Yangtze River from early June to early July, which can be postponed in the south and earlier in the north. The main pests of Belgian rhododendron are: leaf roll moth (rolling leaves to eat leaves), waxworm (causing leaflet disease), crown net moth (causing white spots on the leaf surface, leaf back stains). The corresponding pesticides are as follows: effective cyhalothrin 2000 times to control leaf roll moth and crown net moth, trichlorofurol 1000 times, triyne wax 1500Murray 200 times to control wax insects. The main diseases of Belgian rhododendron are black spot, leaf spot, stem blight and so on. They can be controlled by rotation with fungicides such as mancozeb, 3000 times of world height, 600 times of thiophanate, 2000 times of eye mildew, etc., and sprayed every 10-20 days. It should be prevented before rain and treated after rain for a long time, and the prevention and control of Botrytis cinerea should be paid attention to at flowering stage. Botrytis cinerea should be prevented and treated every 7-10 days, with a total of 2-3 times. If you want to improve the quality of flowering, you can use foliar micro-fertilizer (such as Pushibao, Sui Manfeng, Yemianbao) 2-3 times (refer to the specific concentration manual) every 7-10 days before flowering. In addition, water supply should be preferred during flowering, never losing water, and wilting flowers should be picked in time, and the temperature is too low (below 8 ℃) or too high (30 ℃ is also disadvantageous to flowering).
