The latest course on the techniques and methods of planting and Management of eight Immortals

The eight Immortals, also known as Ziyang Flower, is a kind of ornamental flowers and trees often used in parks and scenic spots, with red and blue flowers and colors, which are very beautiful. This kind of flower originated from Sichuan and Japan in China. Because of its shade tolerance, it can be planted even in small courtyards with poor light. Coupled with its large and colorful flowers, it is loved by many flower lovers. Now it is one of the rare flower species in China. Today, the pro-agricultural network brings you the planting and management technology of the eight Immortals.

Growth habit

If we want to raise a kind of flower well, we must first know the growth habits of the flower, so as to create a suitable growth environment for the flower. The eight Immortals like the warm and humid environment, the most suitable growth temperature is 18 ℃ ~ 28 ℃, the overwintering temperature can not be lower than 5 ℃, and its flowering period is from June to August. If the temperature is suitable and can be maintained at about 16 ℃, the flowering period will be prolonged accordingly, while the high temperature will make the flowers fade quickly. Although the eight Immortals like the humid environment, they should not be watered too much on weekdays, especially the eight Immortals cultivated indoors in winter had better stay dry slightly, too damp will lead to leaf rot and other problems. The color of the eight Immortals is controllable, when the soil is acidic, the color of the flower is blue; when the soil is alkaline, the color of the flower is red, which is like purple litmus, but the reaction is completely opposite, so in the process of planting, if you need the flower to be blue, you can apply aluminum sulfate, and if you need the flower to be red, you can apply lime to the soil.

Reproduction method

Baxian flower can be propagated by means of ramet, striping, cuttage and so on. Cuttings can be carried out all year round in the greenhouse. Generally from May to June, combined with early spring pruning and post-anthesis plastic surgery. Select semi-lignified and pest-free branches, each section 10 to 15 cm long, retaining 2 to 3 nodes and 1 to 2 leaves at the top, and insert them in a seedbed with river sand or vermiculite as substrate to shade properly. Keep the substrate moist, the air humidity above 80%, and begin to take root in about 18 days. After that, the frequency of water spraying was gradually reduced and the light was increased, and it could be transplanted in about 1 month.

Planting management

Planting cuttings should be put into pot in time after rooting. Baxianhua prefers loose, fertile and well-drained soil. It is usually prepared with rotten leaf soil, garden soil and organic fertilizer at the ratio of 4 ∶ 4 ∶ 2. Grass carbon, perlite and organic fertilizer should be prepared at the ratio of 6 ∶ 2 ∶ 2 for large-scale production and thoroughly sterilized before use.

1, fertilization: eight immortal flowers like fertilizer, generally every half a month to pursue organic fertilizer. There is more nitrogen fertilizer in the early growth stage, and more phosphorus and potassium fertilizer in the flower bud differentiation and bud formation stage. 0.1% to 0.2% potassium dihydrogen phosphate can also be sprayed on the leaves for 2 to 3 times, and the fertilization can be stopped after the flower buds are transparent.

2. Watering: the transpiration of the leaves of the eight Immortals is very large, so it must be watered in time, even if the lack of water for a short time wilts, it can also cause the leaf margin to dry up and the flowers to die. Especially in summer, it is necessary to shade and cool down to reduce transpiration and maintain more than 60% air humidity. In addition, the flower color of the eight Immortals is affected by the ph value of the soil and is usually blue in the acidic environment and red in the alkaline environment. Therefore, the ph value of the water should be determined according to the desired color.

3. Temperature: Baxian flower is not resistant to high temperature, and the temperature is required to be between 15 ℃ and 25 ℃. High temperature will dilute the color of dwarf flowers and reduce the quality. After the flower bud is colored, the temperature is kept at 10 ℃ to 12 ℃ to improve the flower color and keep it fresh.

4. Lighting: the eight Immortals are shady, and direct sunlight will cause sunburn, so shade is needed. Usually 60% shading is needed during the growing period, and the inflorescence should also be shaded properly after the color is transparent, so as not to fade and lose its luster.

5. Pruning: the eight Immortals have strong sprouting power and will sprout a lot of vegetative branches at the base of the plant. In order to reduce nutritional loss, they should be erased in time. If the old branch needs to be replaced, a robust vegetative branch can be selected as the reserve branch. Cut it short in time after anthesis and retain 2 or 3 strong buds to promote new shoots.

6. Florescence regulation: in order to make the eight Immortals bloom during the Spring Festival, robust plants of 3 to 5 years old can be selected. After 14 days of low temperature treatment of 2 ℃ to 4 ℃, they are moved into the greenhouse to heat up, keep for 10 ℃ to 20 ℃, and bloom in 50 to 60 days. Pay attention to regular ventilation, maintain good light conditions and high air humidity, and apply organic liquid fertilizer once a month until flowering.

Pest control

Baxian flower has few insect pests, mostly aphids, leaf mites and so on, which can be controlled by spraying internal absorbent agents while ensuring good ventilation. Most of the common diseases are leaf diseases, such as white rot, gray mold, leaf spot and so on, so it is necessary to spray insecticides regularly to prevent the disease, and the diseased leaves can be removed and burned.

The above is the introduction of the planting method of the eight Immortals on the pro-agricultural network. Here, the pro-agricultural network would like to remind everyone that the eight Immortals is a kind of traditional Chinese medicine, but at the same time, it is toxic. If you accidentally eat the eight Immortals, there will be obvious abdominal pain, accompanied by vomiting, weakness and other conditions, and even a coma, so you must not eat it at will in the process of breeding, but there is no need to be too nervous. At present, an antidote for the toxicity of eight Immortals has been developed, and you can see a doctor immediately after eating it by mistake.
