The four seasons are the genus Begonia of the genus Begonia, which is native to Brazil and is a perennial herb. It is also known as begonia, tiger ear, and jellyfish. The four-seasoned sea bream is used as a perennial greenhouse potted flower in traditional production. In recent years, people have applied it to the flower bed layout with excellent results. With the emergence of some relatively heat-tolerant varieties, the Begonia sphenanthera is likely to become one of the most important flower beds. It has the advantages of round planting, multiple flowers and dense, easy planting with other flower beds, and long viewing period. Therefore, it has become more and more popular. It is generally cultivated in spring and autumn.
Light, water, temperature, and topping are the key to good four-season cultivation and management. After the colonization of the four seasons, the sea bream can be directly exposed to sunlight in early spring. With the increase of sunshine, proper shading is required. At the same time should pay attention to the management of water, excessive water prone to rot, rotten buds, rotten branches phenomenon; high temperature and humidity easily lead to various diseases. After planting the seedlings, liquid fertilizer was applied once every 10 days. Pruning long branches and old branches in time to promote new lateral branches and strengthening pruning are beneficial to the appearance of the plant. The cultivated soil conditions require humus-rich, well-drained, neutral or slightly acidic soils that are both afraid of drought and water stains.
The suitable temperature for the growth and flowering of Jellyfish is about 23°C. In the summer, it is semi-yin, cool and well-ventilated. Avoid heat, waterlogging, and strong light. In summer maintenance, follow its "temper".
Sunshade ventilation Four seasons sea otters are very sensitive to sunlight. Once you enter the summer, you need to adjust the lighting time and create an environment suitable for its growth. Shade it. Indoor cultured plants should be placed in a place with scattered light and air circulation. Open the windows at night to ventilate the air.
Moderate watering The four-seasoned seabream prefers a moist environment, but in the hot summer season it is better to have a slightly moister basin. Watering Do not fix the water several times a day or a few days, but at any time pay attention to observe the wet and dry state of the basin soil, see the basin when the white soil can be watered, the amount of water should not be too much. Watering time is about 9 o'clock. It should not be dry or poured as much as possible, but it should be poured thoroughly when it is poured, but it cannot be fully dried and then poured.
Classification Fertilization The fertilization of the four seasons of the sea bream in summer is to be treated differently according to the old and new plants. The new strains that were bred in the autumn of last year may be cooked with thin pancakes after each flower. The ratio of fertilizer to water is preferably 1:5. Once a week, they can be applied twice. After two weeks, they can be re-emerged. Perennial old plants or weak plants, when the temperature is above 25 °C, need to stop fertilizing, to be fertilized after fertilization, to usher in the second flowering season.
Cooling and Humidification In summer, the temperature is high and the air is dry. In addition to the filtering and hurricane treatment for the four seasons, the ground around the plants must be sprinkled with water several times to reduce the temperature and increase the humidity of the control air. Conditional families may set a sand bed at the corner of the balcony or in the courtyard, place the plants on the sand or sit in the sand bed, and sprinkle the sand while watering the plants. Cooling and humidification.
Disease prevention and control of insects in the four seasons under high temperature and humidity conditions, prone to spot bacterial disease. At first, dark brown spots appeared on the leaves, which gradually spread into dark brown boules. Before the onset of illness, it can be sprayed with equal amount of Bordeaux mixture to prevent it, and pay attention to improving cultivation conditions and management methods. At the early stage of disease, the diseased leaves should be removed and burned in time to prevent retransmission. Summer is the high incidence of locusts and red spiders, and they should be promptly treated with pollution-free pesticides.
