Heavy-petaled begonias
Begonia rhizomes are nearly spherical, erect, up to 60 cm tall, with longitudinal edges and glabrous. The flowers are more pink, the bracts are oblong, blunt at the apex, and fall early; the anthers are inverted ovoid, flowering in July and beginning to bear fruit in August. It is produced in Hebei, Henan, Shandong, Shaanxi, Sichuan, Guizhou, Guangxi, Hunan, Hubei, Anhui, Jiangxi, Zhejiang, Fujian and Kunming. It is also found in Japan, Java, Malaysia, and India.
Begonias grow on damp rock walls in valleys, on dense forest rocks beside valley streams, on rocks along ravines and in valley shrublands at altitudes of 100–1100 m. The growth temperature is 10-34 ° C, when the temperature is above 30 ° C, the begonia stops growing into dormancy, growth stagnation below 10 ° C, and the temperature into winter is not less than 10 ° C, otherwise the leaves are susceptible to frost, but the rhizomes are more hardy. It grows rapidly in a warm environment, with lush stems and leaves and bright flowers. Sensitive to the reflection of light. It is generally suitable for growing under morning light and scattered light, and it is easy to cause leaf burns under strong light. The response to the photoperiod is also very pronounced. Under the conditions of short days and night temperature of 21 °C, the flowering period is significantly delayed.
Trout begonias
Begonia is a famous ornamental flower. Dwarf, multi-flowered begonias for setting up summer, autumn flower beds and lawn edges. Potted begonias are often used to decorate living rooms, shop windows or decorate home window sills, balconies, and coffee tables, which are very fresh and elegant. If equipped with a high-quality art hanging basin, hanging indoors, it looks even more cute.

Function indications for cool blood hemostasis, dispersion of stasis, menstrual regulation. It is used for vomiting blood, blood, coughing up blood, avalanche, vaginal discharge, menstrual irregularities, dysentery; external treatment of bruises.
Plant non-test tube efficient fast propagation technique of fast propagation begonias, 46 days after inoculation began to grow leaves
At present, the market potential of begonias is huge, but begonias usually use sowing and cuttings to propagate, which has a long breeding cycle, time-consuming and labor-intensive. Using the plant non-test tube efficient and fast propagation technology invented by researcher Li Changxiao, the begonias are asexually and rapidly multiplied, which can produce large-scale fast reproduction without variation, low cost, short cycle, large scale and industrialization, and quickly supply seedlings to all sectors of society.
Plant non-test tube efficient fast propagation technology is a new plant cloning system, completely out of the laboratory conditions, seedling facilities are simple, compared with conventional seedlings greatly save germplasm materials, labor efficiency is extremely high. By investing in the use of plant non-test tube efficient and fast propagation technology, the investment can be increased geometrically in the short term, and the supply of begonia seedlings alone has a high potential profit. Moreover, it can be multiplied throughout the year, the reproduction coefficient is high, the operation is simple, the survival rate is high, the management is simple, it is convenient for popularization and large-scale production, it overcomes all the shortcomings of conventional technology, and it is a great innovative technology new system in the field of rapid propagation of plants, and it is also a major scientific and technological achievement that is easy to form industrialization.
