What are the breeding methods and precautions of begonia flowers?

In our daily life, many friends have a hobby of planting small plants and potted plants. Raising flowers is the same as keeping pets, so we should pay attention to methods. So today, the plant flower language will explain the cultivation methods and precautions of begonia flowers for everyone. Let's take a look.

The roots of begonia flowers are tender and fragile, so we should pay attention to choosing loose, fertile and well-drained substrates as culture soil. Potted plants can generally be mixed with 7 parts humus soil, 3 parts river sand and a small amount of fermented bean cake fertilizer to prepare culture soil; Or use 4 parts of humus soil, 3 parts of peat soil and 3 parts of river sand to mix loose and well-drained culture soil.

Watering method Begonia flowers can stand out and are most afraid of water accumulation. Whether planted in the ground or potted, it is generally enough to keep the soil moist. The soil of potted begonia flowerpots should not be too wet, and semi-wet strips are best. However, potted plants placed on balconies or highlands should be watered in time; The soil should not be too dry, because the soil is too dry, the absorption of roots is blocked, the leaves of plants are dehydrated, and they are easy to lose nutrition, or they are dry and scorched, which will lead to plant death in serious cases. In spring, water every 3 ~ 5 days; Water every 1 ~ 2 days in summer; Water every 4 ~ 6 days in autumn; Water every half month in winter.

The fertilization method for cultivating begonia flowers in the open field includes applying base fertilizer, digging ditches around the plants and applying decomposed organic fertilizer after flowering every year. After returning to the soil, the water can be fully irrigated to make it absorb slowly, so as to meet the requirements of plant nutritional growth for nutrients. In autumn, according to this method, organic fertilizer mainly composed of phosphorus and potassium fertilizer can be applied once to promote flower bud differentiation of plants and meet the requirements of their reproductive growth for nutrients. Potted begonia flowers can be fertilized according to the season.

When the buds are formed in spring, but they are not open, the decomposed organic liquid fertilizer can be applied once a week at the concentration of 1: 10 or 1: 12, and the flowers are bright in color and huge. After the flowers wither, plants enter the vigorous period of vegetative growth. At this time, fertilizer management should increase the concentration. Generally, apply it every ten days and a half months according to the ratio of 1: 6 or 1: 8, and stop using it in July and August. The concentration of phosphorus and potassium fertilizer in autumn is 1: 10.

Light and temperature require Begonia flowers to bloom mostly in spring, but if the light and temperature are properly managed and treated with special techniques such as cooling and shading, they can bloom again in the autumn of that year. The specific method is: in the hot and rainy mid-July, move the flowerpot to the shade to avoid the rain and cool down. The light is reduced to about 40%, and the watering amount is gradually reduced to control the vegetative growth of plants.

With the passage of time, the watering amount should be gradually reduced until the leaves turn yellow and fall off on their own to promote their dormancy. After that, continue to water a small amount to maintain the life of the plant and not sprout new buds. In this way, after 35 ~ 45 days of dormancy, the plants are placed in light and watered with phosphorus and potassium fertilizers to revive them and germinate flower buds. Generally, after 15 ~ 20 days, you can see bright begonia flowers.

Note: Begonia flowers can be watered once in early spring when combined with fertilization, and once again when the fruit is dry after flowering. Pay attention to the prevention and control of aphids, scarabs and other pests and rot diseases, and it is best to spray lime-sulfur mixture in early spring for prevention and control. Potted begonia flowers should be thinned and fertilized frequently, otherwise excessive fertilization will easily damage the root system and the leaves will die.
