The basic principles of layering propagation The technical points of layering propagation In the world of horticulture enthusiasts, propagating plants is an activity that tests patience and is full of fun. layering propagation, as a common plant propagation method, is not only simple to operate, but also has a high survival rate. It is a favorite breeding method for many families and horticulture enthusiasts. This article will introduce in detail the methods and techniques of layering propagation to help you easily achieve large-scale reproduction of plants at home. Basic principles of layering propagation Layered propagation, also known as squeezing branch propagation, is a method of asexual propagation that uses the natural growth characteristics of plants to bury a section of branches in the soil to take root and germinate, thereby reproducing new plants. This method can retain the excellent characteristics of the mother plant and is one of the preferred methods in horticultural reproduction. Method of layering propagation 1. Choose the right plants: Not all plants are suitable for layering propagation. Plants with better rooting ability are more suitable for using this method. Common plants suitable for layering propagation include crape myrtle, pomegranate, rose, etc.
2. Choose suitable branches: Choose strong annual or biennial branches, with a diameter of 0.5-1 cm. The branches should be free of pests and diseases and have strong growth potential.
3. Laying time: Spring and autumn are the best periods for layering and reproduction. The spring temperature is suitable and the plants grow vigorously; the autumn temperature is moderate, which is conducive to rooting of branches.
4. Lasting steps: a. Girdling the selected branches about 20-30 cm from the top, with a width of about 1 cm.
b. Apply rooting powder to the girdling area to promote rooting.
c. Burial the treated branches into the soil at a depth where the girdling area is just buried into the soil.
d. Use thin wire or string to fix the branches in the soil to prevent them from loosening.
5. Management and maintenance: After layering, pay attention to keeping the soil moist, apply fertilizer appropriately, and regularly check the rooting status of the branches. When the new plant grows to a certain height, it can be separated from the parent plant and planted separately. Technical points of layering propagation 1. Soil selection: layering propagation does not require high soil, but sandy soil with loose, breathable and good drainage is appropriate.
2. Planting density: The density of plants propagated by layering should not be too large, so as not to affect ventilation and light transmission, leading to diseases.
3. Water management: Keep the soil moist, but avoid standing water. When there is high temperature and drought in summer, the number of watering can be increased appropriately.
4. Fertilization: In the early stage of layering propagation, appropriate amounts of nitrogen fertilizer can be applied to promote branch growth. After rooting, phosphorus and potassium fertilizer can be gradually added to promote the growth of new plants.
5. Pest and insect pest control: Regularly inspect plants and prevent pests and diseases found in time.
Layered propagation is a simple and easy plant propagation method with high survival rate. Mastering the methods and techniques of layering propagation can not only meet the needs of family flower cultivation, but also improve the ornamental value of plants. I hope that through the introduction of this article, more gardening enthusiasts can easily master the techniques of layering propagation and allow green plants to thrive in your home.
