Ornamental chrysanthemum potted cultivation method

Abstract

The invention belongs to the technical field of ornamental chrysanthemum breeding, and especially relates to an ornamental chrysanthemum potted cultivation method. The ornamental chrysanthemum potted cultivation method specifically comprises the following steps: 1) using wild chrysanthemum for grafting breeding; 2) using a ridge method to culture ornamental chrysanthemum seedlings; 3) transplanting chrysanthemum seedling potted plant; 4) culturing seedling trunks; 5) pinching and picking buds; 6) shaping and remaining flowers; 7) regulating flowering time; 8) performing flower bud management. The method uses a grafting rapid propagation technology to breed ornamental chrysanthemum, excellent characteristics of an original variety is maintained, and survival rate of breeding of the ornamental chrysanthemum is improved. Cultivation soil has relatively high fertility and good hydrophobic property, and satisfies requirements of fertilizer and moisture and prevents a water logging disaster. Through short-day treatment on the ornamental chrysanthemum, flowering time is promoted to bring forward. Through KT treatment, chlorophyll, nucleic acid, and protein contents of the ornamental chrysanthemum are reduced, cellular structure is protected, and flowering time of the ornamental chrysanthemum is prolonged.

Description

technical field [0001] The invention belongs to the technical field of ornamental flower breeding, in particular to a potted cultivation method of ornamental chrysanthemums. Background technique [0002] Chrysanthemum (formal name used at school Dendranthema morifolium, commonly used chrysanthemum, Latin FlosChrysanthemi), the perennial Asteraceae herbaceous plant, its petal is tongue shape or tube shape. Since ancient times, chrysanthemum, together with plum, orchid, and bamboo, has been called the "Four Gentlemen" of flowers for their unique flowers, postures, colors, and rhymes. The character that is not afraid of severe cold makes people doubly like it. Chrysanthemums are originally produced in my country.

Problems solved by technology

[0006] In view of the above technical problems, the purpose of the present invention is to break through the shortcomings of the existing potted cultivation methods for ornamental chrysanthemums, and provide a potted cultivation method for ornamental chrysanthemums, which uses wild chrysanthemums as the female parent grafting and rapid propagation technology to breed ornamental chrysanthemums. Maintain the excellent characteristics of the original varieties, but also improve the survival rate of ornamental chrysanthemums, and solve the problems of potted chrysanthemums, such as excessive growth, easy lodging, and weak disease resistance; the cultivation soil has high fertility and good hydrophobicity, which can meet the needs of fertilizers. and the demand for water, and can prevent excessive water from causing waterlogging and affecting the growth of ornamental chrysanthemums; through short-day treatment of ornamental chrysanthemums, the sunshine time of ornamental chrysanthemums can reach about 10 hours. At this time, ornamental chrysanthemums will stop vegetative growth, so flower buds Accelerate the differentiation of chrysanthemums and promote the early flowering period; the content of chlorophyll, nucleic acid and protein in ornamental chrysanthemums after KT treatment is reduced, the cell structure is protected and delayed, and the flowering period of ornamental chrysanthemums is prolonged
