The Cultivation Method of Rapid Breeding of Green Onion

Abstract

The invention discloses a cultivation method for rapid breeding of scallions, which comprises the following steps: selecting seeds, accelerating germination, sowing, applying seedling fertilizer, vernalization and cultivating. When accelerating germination, the selected seeds removed from the bud shell are placed in a container, and Spray a salicylic acid solution with a concentration of 0.5mg / L-1.0mg / L in the container containing the seeds, make it submerge the seeds, soak for 3-4h, and then place the tray containing the seeds at a temperature of 0°C-3 ℃ in the seed storage box, refrigerated for 1-3 days, took out and covered the surface of the seeds with wet gauze, placed in a dark place, and germinated for 1-2 days to make them germinate. acid solution, and then take it out and refrigerate it at low temperature, which can quickly release the dormancy of the seeds, increase the gibberellin and cytokinin in the seeds, and promote the germination of the seeds. It can further promote the breeding of scallions and shorten the breeding time.

Description

technical field

[0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a cultivation method for rapid breeding of scallions. Background technique

[0002] Scallions are biennial herbaceous plants of the Liliaceae family, which are widely planted in my country. Therefore, my country has become an important producer and consumer of scallions. Although my country has abundant germplasm resources of scallions, due to the late start of germplasm breeding and breeding of scallions in my country, our country Scallions are still grown as conventional varieties. Not only is the planting period long, but the growth of scallions is not good. Therefore, to change the backward situation of scallions cultivation, the germplasm selection of scallions is the key.

[0003] In recent years, Chinese scientific researchers have carried out a lot of research work on the breeding of scallions, and successfully reported the method of breeding scal...

Embodiment 1

[0025] The cultivation method of scallion fast breeding comprises the steps:

[0026] Seed selection: select the green onion flower buds with vigorous plant growth, high temperature resistance and low cold resistance as green onion seeds;

[0027] Acceleration of germination: put the seeds obtained by removing the shell of the green onion flower buds selected above into a container, and spray a salicylic acid solution with a concentration of 0.5 mg / L into the container containing the seeds, so that the seeds are immersed in the salicylic acid solution and soaked for 3 hours , take out the seeds and drain the salicylic acid solution, put the seeds in a tray, then place the tray containing the seeds in a seed storage box with a temperature of 0°C, refrigerate for 1 day, take it out and cover the surface of the seeds with wet Gauze, put in a dark place, and germinate for 1 day to make it germinate;

[0028] Sowing: When the whitening rate of the above-mentioned germinated seeds ...
