How to maintain the carnation before and after flowering

The species of carnation is low, the stem is similar to bamboo, the leaves are green, the natural flowering period is from May to September, from spring to Mid-Autumn Festival, greenhouse potted plants can blossom for four seasons, very beautiful, but many people are different from how to keep it blooming before and after flowering, and then take the maintenance method before and after flowering.

Fresh-keeping methods of Carnation

1. Moisturizing. When it breeds and prepares to blossom, always pay attention to its water requirements. Generally speaking, the soil must be irrigated immediately after drying, but because it is the gestation of flower buds, the demand for water is relatively large. Therefore, it is necessary to water in time.

At this time, be careful not to be greedy. If you pour too much at a time, it will cause moisture. This plant is very afraid of water. Once poured out, it should be drained in time. In addition, before spraying, you need to spray water around it to increase the humidity of the air, so as to prevent the flower buds from cracking even if they do not open.

Fertilizer. Because it is going to blossom, it must absorb a lot of nutrients for the development of buds. At this point, you need to fatten up every 10 days. The fertilizer used needs to be diluted and can be watered.

3. Temperature. In summer, pay attention to cover it. In winter, put it in a well-ventilated place facing the sun and give it plenty of light.

Maintenance methods of Carnation after flowering

1. Trim. After the flower has withered, it is necessary to cut off the residual flowers at the base of the flower stem in time, and soon the new flower stem will grow again between its leaf axils.

two。 Temperature. Keep the ambient temperature between 14 and 28 degrees to make it blossom for a long time.

Maintenance methods of Carnation in four Seasons

Spring maintenance

Spring is the transitional period from cold winter to plant growth. Protection is particularly important at this time. It's good and the most important thing is watering. After spring is warm, pour water into room temperature to awaken carnations. Don't pour too much, moisturize, soak.

When the temperature rises and stabilizes, the plants are moved outdoors or on the terrace and exposed to sunlight without shelter.

Of course, it can be planted in spring. When the temperature is 15-20 ℃, it can be filled and the seedlings can grow in about 20 days.

Summer maintenance

In the summer high temperature period, it is often in a dormant state, the requirements of fertilizer and water are not high, fertilizer and water can be properly controlled. The interval between outdoor maintenance is about 3 to 5 days, and the interval between sunlight or high temperature is about 2 to 3 days. Rainy days or cold waves can be extended or combined twice; indoor maintenance lasts 4 to 7 days. Extend and shorten appropriately according to the weather conditions. The watering time should be as low as possible in the morning or evening, and the leaves should be kept dry at night.

Carnation is afraid of muggy heat. In indoor farming, it is often necessary to open windows, can not be kept in an air-conditioned room for a long time, or need to move outside for a period of time.

Autumn maintenance

Autumn is a strong season for the growth of carnation. Fertilization and watering should pay attention to a certain amount of time. Outdoor maintenance should be carried out every 4 days. During sunny days or high temperatures, it should be 2-3 days. Rainy days or cold waves can be prolonged or merged twice. Once, about 8 days. It should be kept indoors for 2-6 days and should be extended and shortened according to weather conditions. However, in autumn and autumn, it is necessary to gradually reduce watering.

Put the carnation in a sunny place to fully receive the sun.

Winter maintenance

During winter dormancy, the most important thing is to control watering and fertilization. Watering should be carried out at noon on sunny days, once every 15-20 days, and should be reduced in cloudy days. Fertilize as much as possible. You only need to apply once before entering the winter.

Control methods of carnation diseases

Leaf blight

Symptom

At the beginning of the damaged leaf, the leaf is good yellow and gradually spreads to the base of the leaf. Later, all the leaves withered, the edge of the disease spot was not obvious, and it was gray-white in the later stage, which produced many small black spots. Although the leaves of carnation have no great influence, they are always strange to flowers.

Prevention method

Remove diseased leaves in time, remove severely infected plants and burn them.

Spraying 50% piranol solution or 50% carbendazim 800x solution has a better control effect.

Brown spot disease

Symptom

Brown spot mainly affects leaves, stems and pedicels. There are almost round spots on the leaves of the damaged plants, with grayish white in the middle and yellowish-brown ridges at the edges. The lesions fused with each other and the leaves gradually dried. In addition, when the ambient humidity is high, many black mold layers will appear on the lesions.

Prevention method

After thanking the flowers, reduce the source of infection, clean up the withdrawn parts in time, throw them away, and don't give the bacteria a chance.

In the process of solidification, proper application of phosphorus and potassium fertilizer will enhance the disease resistance of plants.

Timely spraying, when the situation is serious, do not choose only one spray, can be used alternately in 2 or 3 times to prevent bacteria from producing antibodies. In the early stage of the disease, spray prochloraz oil or Guoguang Yintai every 7-10 days, 2-3 times.

Fusarium disease

Symptom

Pathogens are mainly produced in the roots, which slowly wither when the disease occurs, resulting in the loss of leaves and / or more nutrients and reduced resistance. With the spread of the germ, the stem will gradually contract and soften, the leaves near the rhizome will droop, the disease will develop rapidly, and the plant will wither quickly. When the environment is wet, the part of the rhizome will produce white hyphae.

Prevention method

Choose robust planting, strictly disinfect before planting, and do not use diseased soil.

Clean up the dead leaves on the pottery surface in time and clean it thoroughly.

Remove diseased plants in time to avoid affecting the growth of other plants. After changing the basin, spray potassium permanganate or 3% ferrous sulfate or 70%dikesone 500 times in time to avoid recurrence.
