Method for regulating flowering period of limonium bicolor

Abstract

The invention discloses a method for regulating the flowering period of limonium bicolor. The method includes the steps that 1, limonium bicolor seeds are sown on 5-15 May, and limonium bicolor plants grow under natural conditions; 2, overwintering water is supplied on 5-15 October, and low-temperature inducing treatment is carried out; 3, the limonium bicolor plants are transferred into a room from the outside, and gradual temperature raising lasting 6 days is carried out; 4, the temperature is controlled to be 20-25 DEG C, photoperiod regulation lasting three weeks is carried out, the continuous illumination time of every day is controlled to gradually become 12 h from 10 h, and the limonium bicolor plants bolt; 5, the temperature is controlled to be 22-25 DEG C, four-gradient photoperiod regulation lasting five weeks is carried out, the continuous illumination time of every day is controlled to gradually become 15-16 h from 12-13 h, and the limonium bicolor plants flower. According to the method, limonium bicolor flowers in the current year instead of flowering in two years, the production efficiency of flower products is improved, and the flowering period is regulated to be around the Spring Festival. By means of the method, the steppe ecology and the biological diversity are protected, and the living environment of urban residents is beautified.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for regulating the flowering period of Limonium bicolor. Background technique [0002] Limonium bicolor is a biennial plant belonging to the family Plumbaceae and the genus Limonium bicolor, which was once widely distributed in the grasslands of Inner Mongolia in my country. Since the 1990s, due to grassland degradation and artificial illegal digging and harvesting, the number of Limonium bicolor on the grassland has decreased significantly, and it is now rare to see. [0003] Limonium bicolor is a typical biennial plant. After germination in the first year, only creeping basal leaves grow, no stems, no inflorescences, and the leaves dry and fall off in winter. The basal leaves grow again in the spring of the second year, and the bulbous inflorescences grow from June to July, and bloom gradually in July. When Limonium bicolor blooms, each small flower has yellow petals and p...

AI Technical Summary

Problems solved by technology

[0004] In recent years, some sporadic domestication and breeding of Limonium bicolor have been carried out in my country, but these works mainly focus on cultivation management and tissue culture, which solve the technical limitations of reproduction, but do not change the necessary conditions for biennial plants. The characteristic of flowering after two growing seasons

Therefore, although the dried flowers of Limonium bicolor are very popular among people, the flowering cycle is very long, especially Limonium bicolor blooms in summer, which coincides with other gorgeous flowers, so the benefit is low
