Rieger's Family Conservation Technology
Rieger Begonia is a perennial herb belonging to the genus Begoniaceae of the Begonia family. Because of its long flowering period, rich flower color, green foliage, and full plant type, it is an excellent variety for beautifying the indoor environment in winter and is also the main species of indoor flowering plants in the four seasons. Family conservation Rieger Begonia is different from the large-scale greenhouse production. If you can create suitable environmental conditions, Rieger Begonia will add a bit of color to your family. 1. The temperature of the growth and development of Rieger Begonia is 18°C ​​to 22°C. The focus of family conservation is to keep warm in the winter, and the minimum temperature must not be lower than 15°C. Since winter Rieger Begonia is still in a period of flowering and blooming, it should be placed as far as possible indoors in a sunny location facing south, such as on a window sill in the interior. But be careful not to get too close to the heater so as not to burn the leaves and leaves. In the summer when temperatures above 28°C occur, cool down measures should be taken, such as putting in air-conditioned rooms or shading at noon. 2, water basin should be kept moist, not dry and too wet; too dry will lead to dehydration and wilting, in serious cases the whole plant withered; basin soil too wet, water fills the gaps in the soil, causing severe oxygen deficiency in the soil, This in turn affects root respiration and causes death; basin soil is also prone to provide opportunities for the infection of fungi and bacterial diseases, thereby affecting the ornamental value of Ryger Begonia. The watering of the Rieger Begonia usually depends on the weather conditions, and it is generally faster to evaporate in summer. The water demand is relatively high. The watering should be in the morning or evening. The number of watering depends on the degree of wetness of the basin. Watering in winter is preferred to be at noon on sunny days. The water temperature should be similar to the indoor air temperature so as not to cause the roots to be stimulated to die due to the low water temperature. It is best to use humidifiers to increase the air humidity. Sprayers can also be used to spray fine mist on the foliage. See the damp leaves, but do not spray water on the flowers. 3. Fertilization Fertilizing regularly is particularly important in the conservation of Rieger Begonia. Nitrogen fertilizer is the main fertilizer for small seedlings to promote its growth and development. With the growth of plants, the amount of nitrogen fertilizer should be reduced, and the content of phosphorus and potassium fertilizer should be gradually increased. The amount of fertilizer should be increased before flowering, and the foliar spray fertilizer can also be applied properly. The concentration of foliar fertilizer should not be too large and be controlled at 1% to 2%. In between, the spray should be uniform and both sides of the leaf should be sprayed. 4. Insect pruning During the growth period, it is necessary to carry out topping to promote the emergence of lateral branches to achieve fullness of the plant type, and to remove excess buds in time so as to avoid excessive consumption of nutrients and affect the development of other flowers. 5. Diseases and pests family cultivation The Rygonia pulchricus has less pests and diseases. Regular spraying of bactericides to prevent bacterial soft rot and powdery mildew can be sprayed with agricultural streptomycin 200ug/g and more than 1000 times spray of statin; Pesticides contaminate the air, and can be used to make some soil-based pesticides. The control effect is good. Now, there are several for reference: (1) The ginger juice is added with water and sprayed at a ratio of 1:25 to control the germination of soft rot and other pathogenic spores ( 2), 50 grams of dried chili, add water 50 times, cook for half an hour, take the supernatant liquid spray leaf surface, can effectively control aphids, spider mites.
