Problems solved by technology

[0004] The method for cultivating wheat seedlings provided by the present invention solves the problem that in the prior art, the sand-based culture medium has many particles, which are easy to scatter everywhere and are not easy to preserve, and the disinfection of granular materials is inconvenient, which may easily lead to insufficient disinfection, which eventually leads to the failure of wheat seeds. The problem of mildew

Embodiment 1

[0028] S1, wheat germination: screening out healthy, mildew-free, and non-damaged wheat seeds for germination culture to obtain germinated wheat seeds;

[0029] The step of described germination cultivation is:

[0030] (1) putting the wheat seeds in hydrogen peroxide with a volume fraction of 1% for immersion and disinfection, and the soaking time is 30-40min to obtain the sterilized wheat seeds;

[0031] (2) Soak the sterilized wheat seeds in the germination solution until the wheat germinates to obtain the germinated wheat seeds;

[0032] The germination solution is mixed with hydrogen peroxide with a volume fraction of 1% and Sophora flavescens juice in a volume ratio of 1:2; wherein, the preparation method of 1L Sophora flavescens juice is: take 100g of washed fresh Sophora flavescens, cut into Sophora flavescens slices with a thickness of 0.5-1cm, then put the flavescens slices in 500ml water and boil for 1.5h, filter, collect the filter solution, and finally make up 1L...

Abstract

The invention discloses a culture method of wheat seedlings. The culture method comprises: wheat germination accelerating; with a porous sponge as a substrate carrier, injecting a culture medium into the porous sponge to obtain a sponge based culture medium, wherein the structure of the porous sponge is as follows: a blocky sponge is cut out to form a plurality of seed passages; each seed passage is in a curved shape, and the outlet of the seed passage is located in the upper surface of the blocky sponge, while the bottom of the seed passage is located in the blocky sponge; and carrying out seedling culture until the wheat seedlings are grown. According to the invention, using the porous sponge as the culture medium carrier, the problem of particle scattering everywhere of a sand-based culture medium is avoided; sufficient disinfection using hydrogen peroxide is ensured, thereby effectively preventing wheat seed mildewing, and water is not prone to loss and evaporation. The germination liquid and the culture medium used in the seedling culture process can quickly break the dormancy state of seeds and improves the wheat germination efficiency.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating wheat seedlings. Background technique [0002] Wheat is an important crop product in my country, and its yield and quality are affected by conditions such as wheat variety, climate, soil, farming system, and cultivation methods. Due to the large population of our country, the annual demand for wheat is very large. Breeding new wheat varieties with excellent traits such as high yield, disease resistance, and lodging resistance has always been a topic of concern to scientists. [0003] Breeding methods for new wheat varieties mainly include traditional hybrid breeding, recurrent selection breeding for dwarf sclerocytosis, and transgenic breeding. These breeding methods all involve wheat seedling cultivation experiments. Usually, the culture medium used for the cultivation of wheat seedlings is a sand-based medium, and scientific resear...
