A kind of large-scale production method of Gypsophila plug seedlings

Abstract

The invention provides a large-scale production method of gypsophila paniculata L potted seedlings. The large-scale production method comprises the following steps: selecting newly germinated branch buds on a strong branch in December as explants, and carrying out induction, multiplication, seedling strengthening, rooting culture, ex vitro cutting and rooting maintenance, and potted seedling fieldplanting and maintenance, thus finally obtaining high-quality gypsophila paniculata L potted seedlings. The large-scale production method provided by the invention is characterized in that an LED (Light Emitting Diode) light recipe adopted during induction and multiplication stages comprises red light, blue light and white light which are 5 to 2 to 3 in ratio, and the LED light recipe adopted during seedling strengthening and rooting culture stages comprises red light, blue light, white light and far red light which are 5 to 1 to 2 to 2 in ratio; compared with a traditional fluorescent lamp,the electric energy is saved by 43.7 to 53 percent, and meanwhile, the multiplication rate and the seedling strengthening rate are respectively increased by 24.1 percent and 40 percent; rooting seedlings can be preserved at low cost for a long term only on the premise of water supply after the ex vitro cutting, flexible and sufficient supply of seed seedlings can be ensured, a high-quality gypsophila paniculata L potted seedling field planting and maintaining technology is established, and the large-scale production of the gypsophila paniculata L potted seedlings is realized.

Description

technical field [0001] The invention belongs to the technical field of flower seedling propagation. Specifically relates to a method for producing gypsophila plug seedlings. Background technique [0002] Gypsophila paniculata L., formerly known as Gypsophila paniculata L., also known as Gypsophila paniculata L. Caryophyllaceae stone flower is a perennial herb. There are wild resources distributed in the Altai Mountains and Taxkorgan in Xinjiang, my country. The roots and stems can be used for medicinal purposes, and are now mainly used for cut flower cultivation. [0003] The annual planting area of ​​Gypsophila in Yunnan is about 6,000 mu, and the planting area and output account for more than 90% of the national total. The existing Gypsophila seedlings are produced mainly through two methods of cutting propagation and tissue culture propagation. The cutting propagation method has disadvantages such as strong seasonality, low reproduction coefficient and low efficiency; ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problems of high energy consumption of artificial light source and air-conditioning cooling, low rate of strong seedlings and lack of plug seedling production of Gypsophila gypsophila in tissue culture and breeding, the present invention screens and evaluates Gypsophila plant light source, plugs The research and development of specifications and substrate ratios provide a large-scale production method for Gypsophila seedlings
