Cuttage breeding method of dahlia pinnata

Abstract

The invention relates to a cottage breeding method of dahlia pinnata. The cottage breeding method of dahlia pinnate comprises the steps of (1) selecting cuttings; (2) pruning cutting wounds of dahlia pinnata; (3) disinfecting; (4) temperature processing; (5) matrix preparing; (6) cutting; (7) controlling growth conditions: putting the cuttings obtained in step (6) in greenhouse with temperature of 20-33 DEG C, air humidity of 85-92%, and illumination of 550-700 lx. The cottage breeding method of dahlia pinnata refers to a seedling method that a portion of vegetative organs of dahlia pinnata is taken as the propagation material, and the propagation material is inserted in to a matrix with a certain proportion of garden soil, coir, vermiculite and perlite. The method promotes rooting, germinating, and growing into complete plants. The cuttings can preserve hereditary of the mother plants, can grow, develop, and show the same traits as the mother plants under suitable conditions, and significantly improve the survival rate of breeding of dahlia pinnata.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a cutting propagation method for small lily flowers. Background technique [0002] Xiaolihua is originally produced in the mountains of Mexico, and is suitable for growing in an environment with fertile land, sufficient sunlight, humid climate, and cool summer. Xiaolihua is a perennial bulbous herb with low plant, bright color, changeable flower type and long flowering period. It is an excellent ground cover plant. It can be used for flower bed arrangement, flower border construction, etc. It can also be potted for ornamental and cut flowers use. [0003] However, due to the characteristics of Xiaolihua that are afraid of heat, cold resistance, waterlogging, and heavy clay, it is easy to die in the cutting propagation process. At present, the main methods of existing Xiaolihua propagation are: 1. Divide the ball Propagation, the root of Xiaolihua is composed of bulbs....

Problems solved by technology

[0003] However, due to the characteristics of Xiaolihua that are afraid of heat, cold resistance, waterlogging, and heavy clay, it is easy to die in the cutting propagation process. At present, the main methods of existing Xiaolihua propagation are: 1. Divide the ball Propagation, the root of Xiaolihua is composed of bulbs. After one year of growth, small balls will grow around the bulbs. After the small balls are fully grown, they can be removed for planting, but the amount is small and cannot become the mainstream of reproduction. Method; 2. Propagate by division. The roots of the small flower that have grown for many years will have multiple bulbs or intertwined with each other. After the permafrost is thawed in spring, separate the stems and root systems, and plant them after separation. This propagation method Time-consuming and labor-intensive, with the lowest reproduction coefficient; 3. Seeding reproduction, that is, sexual reproduction in the traditional sense. For Xiaolihua, if it is not a single species for reproduction, then the isolation of the group will be a difficult problem to solve, so the sowing and reproduction A good group isolation method is needed to become the mainstream of Xiaolihua breeding
