How to grow Flower Tobacco planting methods and points for attention

Flower tobacco is a kind of plant with high ornamental value, which is mainly ornamental to flowers. The color of flowers is generally red. At present, it is distributed in many parts of our country. Nowadays, many people choose to grow flower tobacco, but before planting, the topic that everyone must be most concerned about is its planting technology.

How to grow flower tobacco

1. After the seeds are ripe, cut the flowers with large and colorful flowers and dry them to leave the seeds. Spring and autumn are the sowing time, and sowing in early spring is the best. Sowing can be directly sowed in the open field seedbed, can also be sown with a burrowing tray.

2. Directly sowing in the open field seedling bed, the soil spreads more diseases and insect pests, the ground temperature is lower, and the moisture and humidity are not easy to control, which affects the germination rate. At present, most flower producers use hole tray to raise seedlings, which has high survival rate and strong seedlings, and it is also easy to count the germination rate.

3. The seedling substrate requires loose soil, good permeability, water and fertilizer conservation, clean and disease-free, and high fertility. Commonly used substrates are peat soil, coconut bran, perlite, vermiculite, generally mixed use.

4. After the plate is installed, you can sow seeds, usually 1 grain per hole. After sowing, there is no need to cover the soil, water is thoroughly watered, so that the seeds are in full contact with the substrate. Keep the substrate moist, cover the seeding tray with glass or transparent plastic film to maintain air humidity, and keep warm in winter. In summer, the film can not be covered, or the film is not sealed, and both sides must be ventilated. When sowing in summer, it must be shaded.

Planting method of flower tobacco

1. Preparation of sowing substrate. If we want to sow the seeds of flower tobacco, we must first prepare the culture medium. We can choose imported peat, because the quality of this peat is better, peat is used as sowing substrate because peat has good ventilation and ventilation, and it is very moisturizing. It is very suitable for the germination and growth of flower tobacco seeds to maintain the pH value of the medium between 5.5 and 5.8. Before sowing, we should first pour the peat as a culture medium into water to make it have sufficient humidity.

2. The sowing method of seeds. When we sow flower tobacco seeds, we just sow the seeds of flower tobacco directly on the prepared culture medium without covering the soil. Proper light is beneficial to the germination of flower tobacco seeds and maintain a certain degree of humidity, but not too wet. The temperature of the soil should be maintained between 24 °C and 26 °C. If the soil is deep enough, it will take three to five days to grow the young roots of flower tobacco.

3. Maintenance after planting and sowing. After a period of time, the flower tobacco seeds will sprout, and at this time the soil moisture can be slightly reduced, and some low concentration liquid fertilizer can be used to promote the growth of the buds. After the root system of flower tobacco gradually develops, we can slightly increase the concentration of liquid fertilizer, and the light should also be increased appropriately. We should water the flower tobacco according to a certain law, not at will.

Matters needing attention of flower tobacco

After the planting survived, the heart was removed once, which made it more branched. During the rainy season, it is necessary to prevent long-term dampness, and the suitable temperature for childbearing is about 10-25 degrees C. The maintenance process is extensive and simple. Applying effective fertilizer several times after the beginning of spring will not only grow well, but also promote flowering. Due to the long flowering period and bright colors, ground and potted plants are very suitable.

Disease Control of Flower Tobacco

1. Mosaic disease. Prevention and treatment methods: at the initial stage of the disease, 1.5% Zhiyangling emulsion, virus Bike wettable powder or 70% methyl topiramate were applied at the initial stage. Once a week, 2 ~ 3 times in a row, alternate use of drugs to prevent drug resistance.

2. Bacterial wilt. Prevention and treatment methods: agricultural streptomycin 4000 times or 40% desenamine aqueous solution can be used alternately at the initial stage of the disease, root irrigation once every 7-10 days, continuous 2-3 times, 300-500ml per plant, can also be foliar spraying.

In fact, the planting of flower tobacco is not difficult, first of all to choose a good place, and then such as the proportion of sowing. After planting, we must do a good job in management, timely heart-picking and pest prevention are inevitable. Only in this way can we ensure the growth of flower tobacco.
