How to raise Xifu Begonia in spring
Spring returns to the earth, which is the critical period for Xifu Begonia to sprout branches and expand leaves. As one of the famous traditional flowers in China, its pink and white flowers and strong branches complement each other, making it popular among horticulturists. If you want to harvest trees and flowers in spring, it is crucial to master scientific maintenance skills. Spring pruning techniques, pruning principles and timing of Xifu Begonia, pruning is most suitable before germination in early spring. The principle of "three cuts and three retention" is adopted: cut off sick and weak branches to retain strong branches, cut off inner branches to retain outer branches, and cut off loose branches to retain flower buds. Special attention should be paid to renewing and pruning branches more than 5 years old to promote the germination of new branches. Tool disinfection and wound treatment Use 75% alcohol to disinfect pruning shears, and maintain a 45-degree angle for oblique incisions. Apply gardening healing agent promptly after pruning to prevent germs from invading the wound. Xifu Begonia Light Management Full sunshine maintenance advantages You need to ensure more than 6 hours of direct light every day. The south-facing balcony or courtyard is the ideal location. Adequate light can increase flower bud differentiation by 40%, and petal thickness by 25%. Special weather requires manual light replenishment in response to continuous rainy seasons. LED plant growth lights are replenished for 2-3 hours a day, and the spectrum selects a combination of 400-500nm blue light and 600-700nm red light. Cold protection measures for open field cultivation Temperature gradient control establishes a "three-layer protection" system: the surface is covered with a 5 cm pine scale insulation layer, the trunk is wrapped with a linen anti-freezing layer, and the crown is built with a transparent rainproof film. Ensure that the temperature difference between day and night does not exceed 8℃. Cold wave emergency treatment When it is cold in spring, spray 0.2% potassium dihydrogen phosphate solution to improve cold resistance, and use smoking to increase the small environment temperature by 2-3℃. The scientific fertilization plan nutrient ratio formula is applied according to the ratio of N:P:K=1:2:1.5, and calcium and magnesium fertilizers are added during the germination period. It is recommended to use decomposed sheep manure (3kg/plant) combined with slow-release fertilizer (50g/plant). Fertilization time node Apply base fertilizer before and after the sting, and apply top fertilizer once for Qingming and Guyu. The circular ditch application method is used, and a 15-cm deep trench is opened 30cm away from the main stem to fertilize.
Through systematic maintenance and management, Xifu Begonia can not only increase the flowering volume by 60% that year, but also form a beautiful tree structure. Regularly observe the color of new leaves and flower bud density, and adjust maintenance strategies in a timely manner, so that this traditional famous flower will bloom charming in spring.
