Seasonal sea otters are very sensitive to sunlight. Once they enter the summer, they need to adjust the lighting time and create an environment suitable for their growth. From the middle of May to the beginning of June from 10 to 16 o'clock and from the middle of June to the end of August from 8 to 18 o'clock, it is necessary to carry out sunshade treatment. 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 sea bream prefers a moist environment, but in the hot summer season it is better to use 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. Category fertilization Summer fertilization in the four seasons is different according to the old and new plants. New strains that were propagated in the autumn of last year may be cooked with thin pancakes after each flower. Fertilizer ratio of 1:5 is appropriate. Once a week, they can be applied twice. After two weeks, they can bloom again. 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 shading and ventilation of the four seasons, it is necessary to sprinkle water around the plants several times a day to reduce the temperature and increase the air humidity. 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 pest control Seasonal sea lice are prone to spot bacterial disease under conditions of high temperature and high humidity. 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. 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, we have to follow its "temper".
