How to manage osmanthus spring
As one of the top ten famous traditional flowers in China, osmanthus is deeply loved by people for its rich fragrance. Spring is a critical period for osmanthus to sprout and expand leaves. Scientific and reasonable management can not only promote flower bud differentiation, but also lay a foundation for healthy growth throughout the year. This article will systematically explain the core points of spring management of osmanthus osmanthus from water regulation, nutrient supply to pest and disease control. Spring Water Management Skills Watering Amount and Timing Composition When the temperature stabilizes above 15℃, it is recommended to adopt the principle of "seeing dry, seeing wet" and insert a bamboo stick into the soil 3 cm away to detect humidity. It is recommended to use the dipping pot method for potted osmanthus. Place the flower pot in a water container and soak it for 15 minutes to ensure that the root system fully absorbs water. In open field cultivation, attention should be paid to loosening soil in time after rain to avoid stagnant water and rotten roots. Special climate response plan The northern region is windy and dry in spring, so wind barriers can be set up around the plants, and leaf spray can be carried out every morning and evening. Drainage ditches should be prepared in advance during the rainy season of southern plum blossoms, and carbendazim should be sprayed after continuous rainy days to prevent root rot. A scientific fertilization system was established and combined with base and topdressing. Before germination in early March, a circular ditch was dug along the projection of the crown and applied decomposed soybean cake fertilizer (2-3kg per plant). During the new shoot growth period in mid-April, urea (0.2% solution) and potassium dihydrogen phosphate (0.1% solution) are alternately used for foliar topdressing every week. Advanced fertilizer ratio skills adjust the formula for different varieties: increase the ratio of phosphorus and potassium (N:P:K=1:2:2) for Dangui, and appropriately increase the nitrogen content for Sijigui. It is recommended to use slow-release fertilizer (Aolu 318s) combined with bio-organic fertilizer for continuous (G-Y) nutrients in potted plants. Comprehensive pest and disease control strategy Physical control first use a soft brush to clean the gaps in branches and branches every month, and hang yellow sticky insect boards to trap aphids. Scale insects were found to be coated with alcohol cotton swabs, and (T-J) The infected leaves were removed in time and burned. Chemical prevention and control key points spray lime sulfur mixture (3 degrees of baume) in late March to clear the garden. Use imidacloprid (diluted 2000 times) for aphids and abamectin (diluted 1500 times) for red spiders. Pay attention to alternating use of different pesticides to avoid drug resistance.
Through precise water regulation, scientific nutrient supply and systematic pest and disease control, we can not only ensure the healthy growth of osmanthus in spring, but also promote flower bud differentiation, laying the foundation for the full autumn tree of golden osmanthus. It is recommended to make a maintenance log every month, record data such as new tip length and leaf status, and adjust the management plan in a timely manner so that the osmanthus blossom with its intoxicating fragrance under your careful care.
