Plant cutting, as an important means of plant propagation, has been widely used in horticulture and agricultural production. This method of propagation is not only easy to operate but also fast in propagation speed and high in survival rate. It is an important part of modern horticultural technology. This article will introduce the relevant knowledge of plant cutting in detail to help readers better understand and apply this technology.
The definition and principle of plant cuttingPlant cutting, also known as cutting propagation, refers to the use of plant stem segments (such as branches, vines, etc.) as propagation materials. Through proper treatment and cultivation, new roots and buds are formed under suitable conditions to create new plants. The principle of plant cutting is to utilize the plant's own regenerative ability. By cutting the plant stem segments, it stimulates the production of new roots and buds, thus achieving propagation.
Types and characteristics of plant cutting1. Hardwood cutting: Suitable for plants with a higher degree of lignification, such as roses and Chinese roses. Hardwood cutting has a higher survival rate but a slower propagation speed.
2. Softwood cutting: Suitable for plants with a lower degree of lignification, such as chrysanthemums and crape myrtles. Softwood cutting has a faster propagation speed but a relatively lower survival rate.
3. Leaf cutting: Suitable for plants that propagate from leaves, such as rubber trees and devil's ivy. Leaf cutting is simple to operate but has an unstable propagation effect.
4. Root cutting: Suitable for plants that propagate from roots, such as peonies and peony trees. Root cutting has a fast propagation speed but is more difficult to operate.
Steps and precautions of plant cutting1. Selecting suitable cuttings: Choose healthy, disease-free stem segments as cuttings, usually 10-15 cm in length.
2. Cutting treatment: Cut half of the leaves of the cutting to reduce water evaporation. For cuttings with a higher degree of lignification, a rooting hormone treatment can be applied.
3. Inserting into the matrix: Insert the treated cutting into the matrix, with a depth of about 1/3 of the cutting's length.
4. Watering and maintenance: After inserting the cutting into the matrix, water thoroughly and keep the matrix moist. Regularly check the growth of the cutting and adjust maintenance measures in a timely manner.
5. Precautions: Avoid direct sunlight, maintain suitable temperature and humidity, and pay attention to the prevention and control of diseases and pests to ensure the healthy growth of the cutting.
Application and advantages of plant cutting1. Wide range of application: Plant cutting is suitable for the propagation of various plants, such as flowers, vegetables, and fruit trees.
2. Fast propagation speed: Compared with seed propagation, plant cutting has a faster propagation speed, which is beneficial for the promotion and updating of varieties.
3. High survival rate: With proper operation and maintenance, the survival rate of plant cutting is high, which is beneficial for saving propagation costs.
4. Maintaining excellent traits: Plant cutting propagation can maintain the excellent traits of the original plant, which is beneficial for variety improvement.
As an efficient and easy propagation method, plant cutting has a broad application prospect in horticulture and agricultural production. Understanding the relevant knowledge of plant cutting can help improve propagation results, reduce production costs, and provide strong support for China's horticulture and agricultural production.
