How to plant a string of scarlet planting techniques and matters needing attention

A string of red names is very distinctive, but it does not feel so strange to associate this name with a string of red plants, but it will feel just right. Why on earth is this? Because a string of red flowers is arranged in the form of a string like Tomatoes on sticks.

How to plant a string of red

1. Sunshine: a string of red is a light-loving flower, and the cultivation site must have sufficient light, which is very beneficial to the growth and development of a string of red. If the light is not enough, the plant is easy to grow, the stem and leaf is slender, the leaf color is light green, if the light is poor for a long time, the leaf becomes yellow and falls off. If flowering plants are placed in places with poor light, the flowers are often not bright and easy to fall off. Sensitive to photoperiod, short-day light promotes the blooming of a bunch of safflower.

2. Temperature: a bunch of saffron is sensitive to temperature. Seeds germinate at 21-23 degrees, it is difficult to germinate below 15 ℃, and irregular below 20 ℃. 7: 13 ℃ is suitable for seedling stage in winter, and 13: 18 is the best in March-June growth period. When the temperature exceeds 30 ℃, the growth and development of the plant is hindered, and the flowers and leaves become smaller. Therefore, the summer high temperature period needs cooling or proper shading to control the normal growth of a string of red. It is easy to suffer frost injury under low temperature of 5 ℃ for a long time.

3. Pruning: the heart should be picked immediately after a string of red is planted, and at least twice during the growing period, so that the plant is short and strong, the flower branches are many and the flowers are dense.

4. Insect pests: if a string of red plants are prone to rot if they are planted with high temperature, high humidity or insufficient light, attention must be paid to adjusting the temperature to make the air circulate. In addition, a string of red is prone to red spiders, aphids and other insect pests, which can be controlled by spraying dimethoate emulsion 1500 times.

5. Fertilization: a string of red is relatively simple on fertilizer, generally speaking, as long as the basic fertilization is carried out on the planted soil.

Planting techniques and matters needing attention of a string of red

1. Control light and temperature

After planting a bunch of red, put it in a cool place for 3 days to slow down the seedlings. Then put it in the sun to ensure sufficient light. To facilitate the control of light intensity, a suggested scaffolding can be built above the flowerpot. Shade 50% when the light is too strong, especially at noon in summer. Once at a low temperature, it is necessary to put on a plastic film for proper heat preservation, which can usually be done at night or on rainy days.

2. Maintain moisture and humidity

A string of red likes a humid environment and should be sprayed with water once a day, except on rainy days. When watering, the difference between ground temperature and water temperature should not exceed 5 ℃. When the temperature is high, water is often sprayed to the surrounding environment to lower the temperature and increase the humidity of the air. Clean the branches and leaves regularly to improve photosynthesis, once every 15-20 days.

3. Topdressing outside the root is the main method.

Soil provides an important guarantee for the growth and development of flowers, but does not guarantee the healthy growth of plants. It is far from enough to rely on a little water, fertilizer and air in the soil. The specific methods are as follows:

After potted for a week, fertilize outside the root once. Spray once a day for the next three days. The fertilizer was mixed with urea plus potassium dihydrogen phosphate and a small amount of calcium superphosphate. The spraying time is in the early morning and evening.

After that, watering was combined with fertilization, and extra-root fertilization was carried out 8-12 hours after watering. Note that it can be applied around in windy days or in strong light.

4. Control the date of flowering

When sowing in different seasons, the flowering time is also different. Sow in spring and blossom in autumn; sow in greenhouse in autumn and blossom from April to May the following year. The florescence can be controlled in the following ways during flowering:

Cutting off the branches of the buds in time can postpone the flowering period appropriately.

After each flower failure, pick off the residual flowers in time, strengthen the water and fertilizer management, a string of red can re-branch and blossom, prolong the flowering period. And 5. Trimming and topping

Potted plants need to top 3 times after transplanting to inhibit their growth and promote the germination of lateral buds. The plants grown in this way are short and strong, and there are more flower heads.

The value and use of a string of red

Ornamental value: a string of red blossoms will be in full bloom a thick red, very festive, especially suitable for important festivals as decorations. It can also be put at home as a potted plant to add a "warm" vitality.

Medicinal value: a bunch of red whole grass can be used as medicine after harvesting in its growing period, both dry and fresh. It has a good effect of clearing heat and reducing swelling and cooling blood to dispel sores, and a bunch of red smashed on the spot of boils can play its role.

The florescence of a string of red

A string of red blossoms are popular, which are more common festive flowers. The viewing period is very long, and usually the flowers can bloom from summer to autumn. Naturally, the florescence of a string of red flowers is from May to November, but if properly controlled during the breeding period, it can be a string of red flowers in the four seasons.

Planting a string of red needs to pay attention to its growth habits, so as to create a suitable living environment. In the process of planting a string of red, we should not only pay attention to light, heat, soil and water, but also pay attention to the control of the florescence of a string of red. Only in this way can a string of red blooms open in a suitable season and do not affect the normal growth of a string of red.
