How much do you know about flower culture in summer?

The weather is hot in summer, it is necessary to grasp the amount of watering, otherwise too much is easy to die, too little, flowers are easy to dry up, so the basic knowledge of planting needs to know.

For planting common sense, many people do not quite understand, for example, summer is the peak season for the growth of some flowers, but also the dormancy period of some flowers. For watering, can be carried out twice a day, in addition to jasmine, rose and other exuberant flowers, generally not suitable for fertilization, especially into the semi-dormant rhododendron and cyclamen, freesia and other dormant bulbous flowers.

For some semi-overcast and negative flowers, avoid high temperature and direct sunlight in summer, which is the basic common sense of flower planting. Shading measures should be taken and water should be sprayed to cool down. Even drought-tolerant plants such as cacti are at risk of being burned when the temperature exceeds 38 ℃. In addition to daily watering, cuckoos should also spray water on the leaves and the ground to keep moisture and cool down. But there are often heavy rains in summer. After the basin soil is stagnant, nutrients are easy to be lost, so the basin should be tilted to drip out of Rain Water after rain.

The muggy summer is also the season with high incidence of diseases and insect pests. It is necessary to remove the diseased branches and leaves in time, supplemented by drugs for prevention and treatment. You should have such a common sense of planting, such as black spot disease and powdery mildew in summer, the former with Bordeaux liquid, the latter with carbendazim, once every half month. Orchids are prone to anthracnose in plum rain and high temperature seasons. in addition to improving ventilation and light transmission, topiramate can be sprayed every 10 days when the disease occurs. Spray time for summer flowers: before 9: 00 a.m. and after 6: 00 p.m. Watering potted flowers has the following situations and methods:

1. Watering spring, summer and autumn before 10:00 in the morning, and watering at 2 p.m. In winter. The water temperature is close to the soil temperature, slightly higher in winter and lower in summer. However, the temperature difference between water and soil should not exceed about 5 ℃, and the amount of water should be moist from the basin surface to the basin bottom. Watering taboos to block the waist (upper wet and lower dry), nest water (basin bottom stagnant water), but also to avoid the loss of soil and fertilizer in the basin hole, resulting in voids in the basin core, seriously affecting the growth and development of potted flowers. When watering, it should be noted that the flowers that like to dry can control the amount of water, keep the basin soil slightly tidal, and the topsoil can be seen white stubble but not completely dry. Wet flowers often keep the basin soil moist, the topsoil does not see white stubble, but do not accumulate water for a long time.

2. When the weather is dry, the basin soil should be irrigated with appropriate amount of water when it is dry and wet, so as to keep the soil moist. When the weather suddenly changes and water is needed under special circumstances, watering is not limited by the number of times.

3. In the period of vigorous growth and development, potted flowers can release strips, grow plants, promote flowers and strengthen fruit, combined with topdressing can increase the amount of water, keep the topsoil from white stubble and leaves without wilting.

4. in the dormant period or low temperature season, or for squatting seedlings, promoting pregnant buds, preventing excessive growth, and correcting the phenomenon of rhubarb leaves and falling buds, we should properly control the amount of watering, keep the basin soil moist, and combine with loose soil to preserve soil moisture.

5. Will you have such a common sense of planting that in the dry season of spring and autumn, in addition to normal watering and holding water, you should spray water on the leaves and flowers, so as to increase environmental humidity, prevent young leaves from scorching and flowers withering early, and keep the plants fresh? especially flowers in the south should pay more attention to the humid environment. Summer rain after sudden sunny or muggy at night, should spray water to cool down to prevent disease. Spray water at any time to clean the leaf surface to prevent residual water points and leaf dust from condensing into soaking points, which is not easy to remove. Watering potted flowers is a regular labor, the above hot summer, indoor air conditioning can cool down, but close the doors and windows, blocking air circulation.

Therefore, it is very important to know the general knowledge of flower planting. If you keep some flowers with complementary functions in your room, you can act as an "air filter". Most flowers carry out photosynthesis during the day, absorb carbon dioxide, release oxygen, breathe at night, absorb oxygen and release carbon dioxide, while cactus, tile pine and other types are just the opposite. Keeping flowers with complementary functions in the same room can not only balance the content of oxygen and carbon dioxide in the room, but also keep the indoor air fresh.
