Begonia is a perennial grass species of the genus Begonia. Originating from South America and Brazil, it is the most common potted flower currently cultivated. Due to its wide adaptability, long flowering period, good ornamental quality and good flowering and other advantages, it has become an important flower bed and pot plant.
Begonia is hi, warm and cool, with high humidity and moist soil. It is not cold tolerant and dry. The optimum temperature for growth is about 10°C to 30°C, and the temperature in winter is not lower than 10°C. At the appropriate temperature, it can be flowered in four seasons, long flowering period, strong continuous flowering, and it has the characteristics of growing while flowering. When the temperature is too high in the summer, the growth is not good, and it is easy to cause burns, scorch, and susceptibility to diseases. If there is not enough light in winter, the growth is weak, the plants are slender, the leaf color and the flower color become lighter, the leaves are shrinking, and the focal spot appears.
Begonia cultivation soil to peat soil or rot leaf soil, garden soil, sand dubbed, and add the appropriate amount of manure, superphosphate and compound fertilizer is appropriate. In winter, watering should be reduced, and sunlight should be more common. In summer, water should be sprayed on the leaves and leaves should be kept clean. Fertilization should be "bare and hard to apply." Different fertilizers have different effects on Begonia, such as high plant height and outward extension, but when there is little flowering, it indicates excessive N fertilizer. Therefore, the appropriate fertilizer should be selected according to the specific conditions. Generally about 15 days need to apply a liquid fertilizer completely decomposed and diluted with water, when applying fertilizer, avoid applying to the foliage or the root, otherwise it is easy to cause fertilizer damage. The potted Begonia must turn the flower pots regularly to make the lighting uniform and maintain a good plant shape to avoid unilateral growth.
Breeding Begonia generally reproduces by sowing. The common diseases of Begonia are powdery mildew, bacterial blight, insect pests such as aphids, powdered shells, and red spiders, etc., to prevent the spread of diseases and insect pests and infections.
The prevention method is: When planting, avoid dense planting to improve the ventilation and light transmission conditions. When the temperature difference between day and night is large, watering in the evening should be avoided so as to prevent the night temperature from dropping and resulting in excessive humidity. If infected plants and leaves are found, they should be removed or removed immediately. If a disease is found, the use of various fungicides can effectively prevent or suppress the spread of pests and diseases.
The chair side CAD / CAM repair system has obvious advantages in aesthetic effect, operation time, patient participation and operation convenience. Discussion: traditional repair method: after the model is transferred, it will be sent to the technician's room for processing and making the final prosthesis. About one week, the final prosthesis will be tried on, grinded and bonded. The prosthesis was made in the technician's room. The patients need to accept the aesthetic effect of the prosthesis passively without any sense of participation. The implant repair method of chair side CAD / CAM system: obtain computer three-dimensional model by blue light scanning method, design and make personalized abutment and all ceramic restoration on computer, dye, glaze and bond after trial wearing, the whole restoration is made by chair side, patients can directly participate in the restoration design, and feel more involved. Conclusion: in the implant area of the anterior teeth, compared with the traditional implant repair method, the chair side repair system can get more satisfactory results, which is worthy of clinical application and promotion.
