Method for promoting rooting of crassulaceae succulent plant Graptopetalum paraguayense through water planting cuttage

Abstract

The invention discloses a method for promoting rooting of crassulaceae succulent plant Graptopetalum paraguayense through water planting cuttage. The method mainly comprises the steps: (1) preparing cuttage stem; (2) preparing nutrient solution mother solution; (3) preparing culture solution and performing cuttage fixation; (4) performing nutrient solution management; and (5) performing cuttage stem management. The method is characterized in that a water planting research technology is adopted, branches are increased through seedling cuttage propagation, rooting is promoted through water planting, then nutrient regulation is conducted, and plant leaves are promoted to be colored. By adopting the water planting technology, the nutrient environment conditions of succulent plant growth can bestrictly controlled, the succulent plant root growth is promoted, the cost is low, meanwhile, a root system cannot be damaged, materials are convenient to obtain in the experiment, the dynamic characteristics of root growth are observed, the nutrient absorption capacity of the plant and the regulation level of nutrient elements on plant growth and development are researched, and the accuracy andpertinence of a test result are greatly improved.

Description

technical field [0001] The invention relates to the field of plant hydroponic technology, in particular to a hydroponic cutting rooting technology of the sedum succulent plant Ji Luyue. [0002] technical background [0003] During the cultivation process, some succulent plant species such as Ji Miyue of the genus Pinnilia in the sedum family show changes in leaf color due to changes in environmental factors such as light intensity, temperature, and nutrient supply, showing red, purple, yellow, orange, etc. Color, this kind of plants are called colorful-leaf succulents. Because of their high ornamental value and varied leaf colors, colorful-leaf succulents are often widely used in interior decoration, wedding gifts, food processing, garden vertical greening and roof greening. etc., both ornamental and diverse, with remarkable ecological and landscape benefits, and the market demand continues to increase. The reason for the change of the leaf color of succulents is mainly the...

Problems solved by technology

[0004] In recent years, people's research on the root system is mainly through soil culture technology, relying on the drought treatment in the cultivation process to promote the coloring of succulents, and the drought treatment will inevitably affect the growth and development of the plant root system, resulting in an increase in the aging and death rate of the root system. In addition, the root system of succulents is relatively thin, which is not conducive to the selection of succulent root materials and the study of nutrient absorption during the experiment, which seriously affects the accuracy and pertinence of the research results.
