The cultivation method of Prunus davidiana
The delicate pink flowers of Prunus davidiana can always captivate the hearts of flower enthusiasts, but many flower friends find it difficult to achieve the ideal state with their own plants. In fact, it is not difficult to make Prunus davidiana bloom if you master the key maintenance techniques. This article starts from practical maintenance experience and compiles the top five most overlooked management points.
I. Three elements of environmental regulation
Soil mixture determines the survival rate
It is recommended to use a mixed matrix of humus soil: river sand: garden soil = 3:2:5, and add 5% pine needles every year when changing soil to improve aeration. For pot cultivation, it is necessary to lay 3cm of ceramsite at the bottom to enhance drainage and prevent root rot during the rainy season.
Temperature gradient wakes up flower buds
In winter, it is necessary to experience 30-40 days of low temperature (about 5℃) vernalization, and the temperature should be increased by 2-3℃ per week after the beginning of spring. A sudden temperature increase of more than 5℃ can lead to poor development of flower buds. It is recommended to use a temperature-controlled greenhouse in the northern region for transition.
Luminosity intensity affects the number of flowers
Ensure 6 hours of direct sunlight per day, and use a sunshade net to filter 30% of the light during the high-temperature period in summer. For supplemental lighting, choose full-spectrum LED, keeping a distance of 50cm from the plant and providing 3 hours of supplemental light per day.
II. Double core of nutritional management
Dynamic adjustment of fertilizer ratio
In the seedling stage (1-2 years), use a compound fertilizer with N-P-K ratio of 10-15-20, and switch to a 15-10-15 formula for mature plants (3 years and older). Apply additional phosphorus and potassium fertilizer (monopotassium phosphate) before budding, controlling the concentration within 0.2%.
Precise water control strategy
Adopt the 'dry-wet' method, watering thoroughly after the top 3cm of soil dries. When the air humidity is below 40%, mist in the morning and evening to increase humidity. Choose to water in the early morning (6-8 am) during hot weather to avoid scorching the roots at noon.
III. Key points of daily management
Golden period for pruning and shaping
Immediately prune the残花 after spring flowering, retaining 2-3 buds at the base. After autumn defoliation, thin out crossing and weak branches to maintain a tree crown light transmission rate of over 60%.
Key objects for pest control
Hang yellow sticky insect boards from April to May to monitor aphids, and spray pyrethrin immediately upon detecting pest infestation. During the larval stage of the longicorn beetle (June-August), inject 5% cypermethrin emulsion into the虫孔.
Through scientific soil management, precise temperature control, and systematic nutritional supply, Prunus davidiana can achieve a full bloom effect in a home environment. The key is to grasp the special needs of each growth stage and adjust the maintenance strategy in a timely manner. When you see the branches full of flower buds, all the careful care will be rewarded with the most beautiful results.
