Summer flower cultivation management method
General conservation measures watering: high temperature in summer and strong sunlight, greatly speeding up the transpiration of potted water, which is easy to cause drought. Therefore, it is particularly important to properly water the potted flowers in summer.
The temperature of the potting soil is higher at noon in summer, and the roots absorb water faster. If cold water is poured at this time, the temperature of the pot soil will drop suddenly, affecting the normal function of the root system, the root water absorption will be difficult, and the balance of water metabolism of the plant will be destroyed, which will cause the plant to appear wilting and affect growth. Therefore, watering potted flowers in summer should be carried out in the morning or evening. When the soil is not dry, generally do not water, when watering, it should be poured, not only half of the potting soil. If the water is not watered frequently, it will cause poor ventilation of the soil, which will directly affect the normal physiological activities of the root system, and will lead to rotten roots in severe cases. In summer, the potting soil often cracks because it is too dry, so the watering can not be poured once, otherwise the water will leak directly from the soil joint, and most of the potting soil is still very dry. The next day, the plant is still seriously dehydrated, causing wilting. . Therefore, after the first watering, it is necessary to wait for a while, let the soil expand, and the soil cracks are closed and then poured again.
When the potted flowers appear wilting, first move the wilted plants to the sheltered place, and spray a small amount of water on the foliage and potting soil, and then pour the water after the plants have recovered.
Fertilization: In the hot season, in addition to the vigorous growth of flowers such as jasmine and rose, it is generally not suitable for fertilization, especially the rhododendrons that enter the semi-dormant period and the bulbous flowers such as cyclamen and freesia.
Shading: For some semi-yin and negative flowers, avoid high temperature and direct sunlight in summer. Take shading measures and spray water to cool down. Even plants that are highly drought-tolerant, such as cactus, are at risk of being burned when the temperature exceeds 38 °C. In summer, there are often heavy rains. After the water is accumulated in the basin, the nutrients are easily lost. Therefore, the basin should be tilted after the rain and the rainwater should be removed.
Pest Control: Sweltering summer is a high season for pests and diseases. It is necessary to promptly remove the dead leaves of the diseased branches and supplement them with drug control.
orchid
Shade orchids are semi-negative flowers, which should be properly shaded and glare away during the summer. It is best to use a shade net to shade and place the orchid near the water or in a fresh, well-ventilated area.
Fertilization should follow the principle of thin fertilizer and diligence. It depends on the variety of the orchid, the weather, the temperature, and the growth of the plant. Under normal circumstances, Chunlan applies nitrogen and potassium fertilizer in summer; Jianlan applies phosphorus and potassium fertilizer; and Hanlan does not apply any fertilizer. In addition, weak plants should not be fertilized on cloudy days or when the temperature is too high.
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, foliar sprays can be applied at noon to increase humidity.
Spraying orchids are prone to anthrax in the rainy season and high temperature season. In addition to improving ventilation and light transmission conditions, timely prevention and control should occur when diseases occur. Spray Bordeaux or methyl thiophanate every 10 days to control leaf anthracnose; spray 40% omethoate and dicofol every half month to kill scale insects and mites.
It is windy and rainy in summer, especially in heavy rain. It will not only break the blue leaves, but also splash the soil on the basin with blue or blue leaves, which will lead to the occurrence of brown spot on orchid plants. Therefore, in case of heavy rain, it is necessary to properly cover the rain.
Trimming the blue leaves that have been harmed by pests should be cut off in time to avoid infection with other orchids. At the same time, the flowering orchids in summer should also cut off the dead leaves, so as not to consume too much nutrients.
Four seasons sea otter
The suitable temperature for the growth and flowering of the four seasons of sea bream is about 23 °C, and the summer is pleasantly cloudy, cool and well ventilated. Avoid high temperature, waterlogging and direct sunlight. In the summer maintenance, you must follow its "temper".
Shading ventilation should adjust the lighting time to create an environment that adapts to its growth. It should be shaded. Plants cultivated indoors should be placed in a place with scattered light and air circulation. Open windows at night and ventilate.
Moderate watering Four seasons jellyfish prefer a moist environment, but in the hot summer months, the basin is slightly moist. Do not water the water for a few times a day or a few days, but always pay attention to observe the dry and wet conditions of the soil. When the soil is white, you can water it. The amount of water should not be too much. The watering time is good at around 9:00 in the morning. If it is not dry or poured as much as possible, it should be poured through the pouring, but it can't wait until it is completely dry and then poured.
The summer fertilization of the classified fertilization season sea otters should be treated differently according to the new and old plants. In the new plant that was propagated in the autumn of last year, some decomposed thin pizza fertilizer water can be applied after each flowering. The ratio of fertilizer to water is 1:5, once a week, once every 2 times, and it can be flowered again after 2 weeks. For perennial old plants or weak plants, when the temperature is above 25 °C, it is necessary to stop fertilizing and fertilize after the volts to greet the second flowering season.
Cooling and humidifying the water several times a day to the plant and the ground to reduce the temperature and increase the humidity of the air. If conditions permit, a sand bed can be placed at the corner of the balcony or in the courtyard. The plants are placed on the sand surface, and the sand is sprinkled while watering the plants, which can better cool and humidify.
Anti-disease and pest control Under the conditions of high temperature and high humidity, the sea bream is prone to bacterial spot disease. At first, dark brown spots appeared on the leaf surface, which gradually spread to dark brown and brown lines. Pre-existing with Bordeaux liquid spray prevention, and pay attention to improving cultivation conditions and management methods. In the early stage of the disease, the diseased leaves are removed and burned in time to prevent re-distribution. Summer is the high incidence period of aphids and red spiders, and it is necessary to timely control them with pollution-free pesticides.
Clivia
Reducing the amount of fertilizer and applying too much will make the roots unable to absorb. Therefore, the fertilizer is fermented to produce high temperature, and the roots of Clivia are burned.
Control the lighting around the year of June, you must adjust the sunny side to ensure that the blade growth rules are neat. In the summer, let the gentleman see the morning light for 2 hours every day.
Ventilation and cooling in the summer, pay special attention to the placement of Clivia on the pool or basin.
Although proper watering in summer is more than other seasons, it is still necessary to adhere to the principle of “do not dry, water, and waterâ€. Be careful not to let the water into the heart of the leaf when watering, otherwise it will be easy to rot.
The reason for the death of the Chinese rose in the summer season is mostly because the potting soil is not well-matched, and there is no basin change in the spring, and the original potting soil is largely depleted. In this way, the rose cannot withstand high temperatures and die. The rose season is almost semi-dormant in the summer high temperature season. Some growers see that the rose does not bloom or bloom less, which is thought to be due to insufficient fertility. Therefore, more fertilization and fertilization, combined with high temperature in summer, accelerate the fermentation of the fertilizer, and the rose will be Burned roots.
After changing the soil and changing the soil, place it in a cool place for about one week and then carry out normal culture. Remove the board soil and replace it with loose culture soil.
Control fertilization for 15 to 20 days to apply a light fertilizer solution, and then increase the amount of fertilizer in late summer. For the rose that has already died, immediately wash the roots, cut off some branches and put them in a cool place to maintain.
In addition, in the summer, more water should be sprayed on the leaves of the rose. The watering should be carried out in the morning and evening. The branches should not be used for strong pruning. It is also necessary to prevent pests and enhance light and ventilation.
Du Fu
Cooling creates a ventilated and cool environment for flowers. It should be placed in a cool, indoor and outdoor place to let it breathe fresh air.
Moisturizing is to insist on spraying water to the leaves 4 to 5 times a day. At the same time, a pot of water is placed under the pot at the bottom of the day, and the pots are placed on the water basin so that the water can be evaporated by high temperature to create the air humidity required for the flowering of the rhododendron.
The growth of the petals of the translucent rhododendron is often inversely proportional to the light, especially in the high-temperature season. When the light is slightly bright, the petals will shrink. As far as plant growth is concerned, it is impossible to see the sun. In order to solve this problem, insist that the flowers are placed on the balcony every morning from 5:30 to 7:30 to meet the needs of plant growth.
When supplementing nutrients, the rhododendrons are not allowed to supplement nutrients, but they are not necessary to supplement nutrients, especially in the hot season. A small amount of potassium dihydrogen phosphate solution is sprayed once a week onto the foliage. In addition, the use of watermelon juice sprayed leaves, the effect is good.
