Blackish chrysanthemum seed propagation method

Abstract

The invention discloses a blackish chrysanthemum seed propagation method. The blackish chrysanthemum seed propagation method is characterized by comprising the following steps that 1, seeds are processed, wherein screened seeds are sterilized and soaked, are mixed with an organic fertilizer and then are stored under the condition of 1-3 DEG C; 2, varied temperature germination accelerating is performed, the stored seeds are dipped with a nutrient solution and are put in a varied temperature box for varied temperature processing, and then the seeds are immersed into a germination accelerating solution for high-temperature storage; 3, greenhouse culture is performed, cotton yarn cotton is folded into 8 layers, is dipped with the nutrient solution and then is taken out, the germination accelerated seeds are laid flat in middle layers of the cotton yarn cotton till buds emerge, budding seeds are put in test tubes for greenhouse culture; 4, transplanting is performed, wherein an abamectin solution, a nutrient solution and guar gum are added to the organic fertilizer and stirred, and then roots of blackish chrysanthemum seedlings are coated, culturing is performed in a greenhouse for 7-10 days, and then transplanting is performed; 5, daily management is performed, the nutrient solution is used at regular intervals, the abamectin solution is sprayed, and daily lighting time and lighting intensity are controlled.

Description

technical field [0001] The invention belongs to the technical field of chrysanthemum planting, and in particular relates to a method for obtaining black chrysanthemum seed propagation. Background technique [0002] Chrysanthemum is a flower variety native to China. Chrysanthemum has been cultivated in my country as early as 3,000 years ago. "Book of Rites · Moon Order" records a poem "Jiqiu Moon, Ju has Huanghua"; Chrysanthemum is one of the top ten flowers in China.

Problems solved by technology

[0003] The present invention is aimed at the existing problems: the cutting method is generally adopted in the chrysanthemum breeding, its breeding cost is low, and the cultivation method is simple, and its disadvantage is that the root system is underdeveloped after the cutting, the growth rate is slow, and the amount of the selected mother plant is limited, which cannot meet the needs of large populations. Large-scale planting requirements; and the use of tissue culture methods, the equipment is expensive, the operating conditions and procedures are complicated, the cultivation cost is high, and it is not suitable for small and medium-scale planting; the seed breeding method, because the chrysanthemum planting particles are small, the germination rate is low, and the rate of plant diseases and insect pests is high. Seed propagation methods are rarely used in chrysanthemum cultivation
