Culture methods and points for attention of the latest loose-tailed sunflower

Shalea, also known as yellow coconut, purple sunflower, etc., is a cluster evergreen shrub or small tree belonging to Shalea of Palmae family. It originated in Madagascar Island of Africa. Now it is commonly cultivated in some garden units in southern China. Potted plants are used for indoor decoration. It has relevant therapeutic effects on hemoptysis, hematochezia, metrorrhagia, etc. Let's take a look at the breeding methods and precautions of Shalea together!

Growth Habits of Cynanchum esculentum

Samaria is a tropical plant that likes warm, humid and semi-shady environments. Cold resistance is not strong, the temperature below 20℃ leaves yellow, winter minimum temperature needs to be above 10℃, about 5℃ will freeze to death. Therefore, South China can still be cultivated in the open field, and the Yangtze River Basin and its northern areas should be maintained in greenhouses. It grows slowly at seedling stage and rapidly afterwards. Suitable for loose, well-drained, fertile soil. The branches and leaves are dense, evergreen all the year round, and the shade resistance is strong.

Breeding method of albino

1. Plant division: The plant division and reproduction of Sabina chinensis can be carried out all year round. It is usually carried out in April or so in combination with pot change. Select the plants with more tillers at the base, remove part of the old pot soil, and divide them into clusters from the base connection with a sharp knife. The wound should be coated with plant ash or sulfur powder for disinfection. General maintenance 1~2 years can become potted goods.

2. Sowing: If the seeds can be obtained, the harvested fruits can be washed and the seeds soaked in warm water at 35℃ for two days before sowing. With germination and transplantation, more foliar water should be sprayed on sunny days. Generally, the young period grows slowly and grows rapidly after maturity.

Cultivation method of yellow sunflower

1. Transplanting: When installing the seedlings of Areca oleracea, first put 2~3 cm thick coarse matrix as filter layer at the bottom of the pot, sprinkle a layer of fully decomposed organic fertilizer as base fertilizer, the thickness is about 1~2 cm, and then cover a thin layer of matrix, about 1~2 cm thick, and then put them into the plants to separate the fertilizer from the roots and avoid burning the roots.

2. Soil: indoor potted plants should choose acidic soil, and sandy loam with high humus content should be selected in the north. Cultured soil can be made of decaying leaf soil, peat soil plus 1/3 river sand and part of base fertilizer. Tillering bud growth on the rhizome, potted slightly deeper than the original planting, so as not to better root buds. May to October is its vigorous growth period, and sufficient water and fertilizer conditions must be provided.

3. Watering: The watering of the yellow sunflower should follow the principle of dry and wet according to the season. In dry and hot seasons, it should be watered more appropriately. In low temperature and rainy weather, watering should be controlled. In northern areas, especially where water contains more salt and alkali, attention should be paid to regulating soil acidity with black alum. Keep the pot soil moist at ordinary times. Summer and autumn high temperature period, but also often maintain a higher air humidity around the plant, but avoid pot soil water, so as not to cause rotten roots.

4. Fertilization: Sanwei sunflower is generally applied with decomposed liquid fertilizer or compound fertilizer once every 1~2 weeks to promote vigorous growth of plants, thick green leaves, appropriate nitrogen-containing organic fertilizer in summer, and organic flower fertilizer such as sesame sauce residue in winter while maintaining dry and wet state of pot soil.

5. Temperature: The optimum temperature for growth is 20~35℃. If the temperature exceeds 35℃ or is lower than 10℃, the foot leaves will change from green to yellow if the cultivation management is slightly improper. In winter, it is necessary to do a good job of heat preservation and antifreeze. Generally, it is safe to overwinter at about 10℃. If the temperature is too low, the leaves will turn yellow, the tips of the leaves will dry up, and the roots will be damaged, affecting the growth of the next year.

6, light: Shady sunflower summer should be shaded, the most avoid direct sunlight, even if a short period of time exposure will cause the leaves to turn yellow, it is difficult to recover. Like half shade, spring, summer, autumn three seasons should shade 50%. Indoor cultivation and viewing should be placed in a strong scattered light, but also able to withstand a darker environment, but it should be regularly moved to outdoor light for better maintenance, in order to restore, maintain a higher viewing state.

7. Pruning: After 2 years of continuous leaf picking for leaf cutting cultivation, the plants must be fully rejuvenated and the necessary equipment maintenance, mainly the maintenance of shading equipment, because with the continuous growth of plants, shading equipment can not meet the requirements of plant growth height. In typhoon season, it is easy to break the shade net. The second is the rejuvenation of plants.

8, change the pot: every 2~3 years in early spring, change the pot once, old plants can change the pot once every 3~4 years. After changing pots, it should be placed in a semi-shady place with high air humidity, and it is necessary to cut off withered branches and leaves in time.
