Cultivation techniques of dragon-winged begonias

Germination stage of dragon-winged begonias

Potted Container Specifications: "Dragon wings" are best cultivated in 200-hole burrows. This gives the seedling plenty of room to grow so that its curved stem can be better corrected during cultivation. The curvature of the stem branches is more pronounced in small pots. Cultivation substrate: requires soil drainage to be disease-free soil, and the soil pH value is 5. 8―6． 0, conductivity at 0. 5ms／cm。 When the seedbed is sown, the seeds are covered with vermiculite. Temperature: Maintain the temperature at 22-24 ° C as much as possible. Humidity: Relative humidity 95% or higher. Light: No need to fill the light when germinating.

Temperature: After the emergence of young roots, maintain the soil temperature of 2 l °C for 2 weeks. Starting in week 3, the temperature can be reduced to 18 °C. Illumination: Illumination ensures better quality of seedlings. After two weeks of young roots, the light intensity is maintained at 4000-20000luX. Fertilization: Fertilization begins 5 days after germination, such as sowing seeds on the seedbed, fertilization after 10 days of germination. "Dragon wings" require more fertilizer than begonias. It is recommended to apply 50ppm nitrogen fertilizer 2-3 times a week in the first two weeks, and 150-200ppm nitrogen fertilizer 2-3 times per week starting in the third week. Plant growth regulators: The "dragon wings" of potted plants do not require the application of growth regulators. Continue to grow into adult container sizes: Dragon's fin begonias can be widely cultivated in different size containers. Transplantation: Due to the different bending directions of the stems, it is very important to arrange the position of the "dragon wings" in the colonization container reasonably. When arranging the position, the growing shoots are turned outward. When the plant matures and blooms with flowers, the branches remain curved in this direction. Substrate: Seedling roots can begin to apply 200 ppm of nitrogen fertilizer once a week. Note: Fertilization and watering in large quantities delay flowering by l-2 weeks. Plant growth regulator: The trial seed found that spraying Bonzi with 2 ppm once every 2-3 weeks after transplantation was beneficial for growth. When planting in 150 cm pots, in order to make the plant flower early, after the first use of Bonzi, spray 5ppmBonzil-2 times every 1 week to shorten the internodes of the plant, make the branching better, and the leaves more green. With the increase of the length of the sunshine and the increase of the temperature, the spray concentration of Bonzi can be increased to 10 ppm. For cultivation in larger containers, there is no need to increase the spray concentration of Bon2i. Dragon fin trials have shown that planting in each 20 cm pot (3 plants per pot) without any plant growth regulators is better branched and more flowered than planted in 15 cm pots (3 plants per pot). Note: For the application of plant growth regulators, please refer to the local growth regulator varieties.

Sowing to transplantation: 7-8 weeks Transplantation to adult seedlings: 15 cm pots, 2-3 plants per pot: 7-9 weeks 20 cm pots, 3 plants per pot: 8-10 weeks 25-30 cm pots, 4 plants per pot: 9-ll weeks Common problems: "Dragon wing" begonias are not susceptible to insect pests and are extremely susceptible to disease. However, if the cultivation conditions are good, there will generally be no major problems. Non-toxic or low-toxic insecticides can be used for "dragon wings". Application of "Dragon Wings" in Gardens and Landscaping Home growers and landscaping professionals cultivate "Dragon Wings" begonias under the condition of partial shade or shade net, and their cultivation effect is excellent. Regular application of full-effect fertilizer. In the process of landscaping, the "dragon wing" begonia is planted in a pot of 25-30 cm, and its plant height can reach 30-38 cm and the crown width can reach 38-46 cm.
