Summer and autumn are hot and rainy, and there is plenty of sunshine. It is a peak season for some flowers to grow, and some flowers are in a dormant period. To make flowers blossom through this stage, management should be strengthened in terms of watering, shade, and pest control. Iron Tree Due to hot weather in summer, the leaves of cycads often appear to be “sudden†and the color is not green. Therefore, in order to make the leaves moist and dark green, a small amount of ferrous sulphate may be added in the fertilizer water, and when the water is poured, the amount should not be too large. Do not pour water, so as not to cause rot yellow leaves. Potted cycads usually need to be changed once every three years at least. When changing soil, some scrap iron can be placed in the basin to increase the iron quality, which also makes the branches and leaves of the iron tree more green. Disease prevention summer iron trees are highly susceptible to soy disease, 1000 times carbendazim liquid can be used to control. Usually, wipe the leaves with a damp cloth. This not only keeps the branches and leaves of the iron clean, but also enhances the aesthetic appearance. At the same time, it can also prevent the infection of pests and diseases. Reproductive ferrous trees are generally propagated using buried stems, tillers and sowing methods. In summer, the roots of cycads often sprout several axillary buds. At this time, new iron trees can be cut and cultivated. Stem can also be cut into stem segments about 10 cm long, buried in fine soil seedbeds, generally more than 1 month, new leaves can be sprouted. If sowing is used to reproduce, after the fall of the ferrous tree in autumn, the seeds of cycads will be collected and planted in the spring of next year. Under normal circumstances, the pots will be transplanted after two years. orchid The shading orchid is a half-negative flower, and it is necessary to properly shade and avoid bright light in the summer. It is best to use shading nets to shade and place the orchids near water or in fresh, well-ventilated areas. Fertilization should follow the principle of thin fertilizers. It depends on the variety of orchids, the weather, the temperature, and the strength of the plants. Under normal circumstances, Chunlan applies nitrogen and potassium fertilizers in the summer; gladiolus applies phosphorus and potash fertilizers; and Chillran does not apply any fertilizer. In addition, weak plants should not be fertilized on cloudy days or at high temperatures. Although the watering orchid is a fleshy root, in the summer when the light is strong and the temperature is high, the water requirement is relatively increased, and it is necessary to ensure sufficient water. In addition to normal watering, leaf spraying can be performed at noon to increase the humidity. Spraying orchids is prone to anthrax in the rainy season and high temperature season. In addition to improving the conditions for ventilation and light transmission, it is necessary to prevent and cure diseases in time. Bordeaux or thiophanate-methyl was sprayed once every 10 days to control anthrax in leaves. Spraying 40% omethoate and dicofol every half a month killed scale insects and ticks. Preventing rain, windy and rainy in summer, especially heavy rain, not only breaks the blue leaves, but also splashes dirt on the surface of the orchids or orchids, resulting in the occurrence of brown spots in orchids. Therefore, it is necessary to properly shelter the rain when it encounters heavy rain. Trimming should be cut in time for pests that have been harmed by pests so as not to spread to other blue plants. At the same time, the flowering orchids in the summer must also cut off the leaves and leaves of the flowers so as not to consume too much nutrients. Du Fu Cooling creates a ventilated, cool environment for flowers. When air conditioning is on and during the noon lunch break, take the flowers into the air-conditioned room where they can be blown by the cold wind. To get up in the morning or work in the afternoon to turn off the air conditioning, remove the pots from the bedroom and put them in a cool, ventilated place where they can breathe fresh air. The moisturizer first insisted on spraying the leaves 5 times a day. That is, before the light is sprayed in the morning, the light-transmitting back end is sprayed into the room once, and is sprayed once in the air-conditioning room at noon, and once after the air-conditioning room in the afternoon, it is sprayed once in the air-conditioning room at night. At the same time, during the day, a pot of water is placed under the flower pots, and the wooden bar is placed on the basin to allow the pots to sit on the water basin. This way, the water can evaporate with high temperature to create the air humidity needed for azaleas to bloom. Translucent rhododendrons tend to be inversely proportional to the growth of the petals, especially when the flower blooms in the high temperature season. When the light is slightly bright, the petals will shrink. And in terms of plant growth, we must not see the sun. In order to solve this problem, insist on flowering on the south balcony every morning from 5:30 to 7:30 to meet the needs of plant growth. When nourishing the azaleas, they can't make up for it, but they can't help them, especially in the hot season. Spray a small amount of potassium dihydrogen phosphate solution once a week (usually sprayed into the air-conditioned room at night). The use of watermelon juice spray irrigation roots, the effect is good. That is, put the leftover watermelon rind on a plate and stand up. After 1-2 hours, some juice will be drained and gently scooped out with a spoon. The watermelon juice is sprayed on the roots every day. Rose The reason for the death of potted rose in the summer is mostly because the potted soil is not well equipped, there is no soil change in the pot in the spring, and the original pot soil nutrients are exhausted. In this way, the Chinese rose could not withstand high temperatures and die. The Chinese rose is almost semi-dormant during the summer hot season. Some people see that the rose does not bloom or bloom, which is thought to be due to lack of fertility. Therefore, more fertilization and application of concentrated fertilizer, coupled with the summer heat to promote the fermentation of the fertilizer, the Chinese rose will Was burned out of the root system. After changing soil, change the soil and place it in the cool place for about one week before normal cultivation. Remove the cement and replace the loose soil. Control fertilization 15-20 days a light fertilizer solution, then increase the amount of fertilizer in late summer. Wash the roots and replace the soil immediately for the roses that have appeared dead. Cut off some of the branches and put them in the shade and maintain them. In addition, water should be sprayed on the leaves of the Chinese rose in summer, and the watering should be carried out in the morning and early evening. The branches should not be trimmed vigorously, but also pay attention to pest control, and strengthen light and ventilation. Eucalyptus Bonsai Anti-water and wet eucalyptus are most afraid of the soil too wet. Summer is no exception. It's harmless. It's too wet. Eucalyptus is more resistant to drought than wet. Many eucalyptus bonsai (especially new piles) cause death in the summer, mostly due to excessive watering. The high temperature of the water or the improper concentration of fertilization can cause the roots to decay slowly until they are completely rotted, causing the eucalyptus bonsai to die in summer. The light needs to be full of eucalyptus, and it can grow well only in sunny places. Such as lack of light, its slow growth, branches fine, long leaves, pale leaves, fibrous roots are small and weak. Summer is the golden age of eucalyptus roots. Enhancing the light will promote its vigorous life activities, accelerate photosynthesis and metabolism, and make the roots further developed. And general family gardening venues will not have sunlight from morning till night without shading. Even if the roof of the roof platform takes a long time, if the water supply is timely in summer, it will not be possible to harm the banyan bonsai. Can not be pruned except the * water volatile heat, the evaporative cooling function of the leaves of plants is very important. Therefore, in the summer, it is impractical to prune twigs and leaves in large areas so as not to damage their normal regulating functions, causing water in pots and soils to evaporate and roots to suffocate and rot. The light will hardly return to normal growth, and severe cases will soon die. Four Seasons The suitable temperature for the growth and flowering of Jellyfish is about 23°C. In summer, it is half-shadow, cool and well-ventilated. Avoid high temperature, waterlogging, and strong light. In summer maintenance, follow its "temper". Shade ventilation should adjust lighting time and create an environment suitable for its growth. Shave 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 2 weeks, they can be re-emerged. Perennial old plants or weak plants, when the temperature above 25 °C, need to stop fertilizing, fertilization until after the fertilization, to usher in the second flowering season. Cooling and humidifying water several times a day around the plant to reduce the temperature and increase the air humidity. Conditional families can set a sand bed at the corner of the balcony or in the courtyard. Put the plants on the sand or sit in the sand bed. When the plants are watered, the sand will be wet, which can play a good cooling effect. Humidification. Disease prevention and control of pests in the conditions of high temperature and high humidity, the four seasons Begonia prone to spot bacterial disease. At first, dark brown spots appeared on the leaves, which gradually spread into dark brown boules. Bordeaux spray can be used to prevent the onset of the disease, and pay attention to improving the cultivation conditions and management methods. At the beginning of the disease, the diseased leaves will be removed and burned in time to prevent further transmission. Summer is the high incidence of locusts and red spiders, and they should be promptly treated with pollution-free pesticides.
