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 germplasm storage box with a temperature of 0°C, refrigerate for 1 day, take it out and cover the surface of the seeds Wet gauze, put it in a dark place, and accelerate germination for 1 day to make it germinate;

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

Embodiment 2

[0033] The cultivation method of scallion fast breeding comprises the steps:

[0034] Seed selection: select the green onion flower buds with vigorous plant growth, high temperature resistance and low cold resistance as green onion seeds;

[0035] Acceleration of germination: the seeds obtained by removing the shell of the green onion flower buds selected above are placed in a container, and the salicylic acid solution with a concentration of 0.8 mg / L is sprayed into the container with the seeds, so that the salicylic acid solution is immersed in the seeds and soaked for 3.5 h, pull out the seeds and drain the salicylic acid solution, put the seeds in a tray, then place the tray containing the seeds in a germplasm storage box with a temperature of 2°C, refrigerate for 2 days, take them out and cover them on the surface of the seeds Put wet gauze on it, put it in a dark place, and accelerate germination for 1.5 days to make it germinate;

[0036] Sowing: When the whitening rat...

Embodiment 3

[0041] The cultivation method of scallion fast breeding comprises the steps:

[0042] Seed selection: select the green onion flower buds with vigorous plant growth, high temperature resistance and low cold resistance as green onion seeds;

[0043] 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 1.0 mg / L in the container containing the seeds, so that the seeds are immersed in the salicylic acid solution and soaked for 4 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 germplasm storage box with a temperature of 3°C, refrigerate for 3 days, take it out and cover the surface of the seeds Wet gauze, put it in a dark place, and accelerate germination for 2 days to make it germinate;

Abstract

The invention discloses a cultivation method for rapid breeding of allium fistulosum. The method comprises the following steps of seed selection, germination acceleration, sowing, seedling lifting fertilizer application, vernalization and cultivation. During germination acceleration, selected seeds without bud shells are placed in a container, a salicylic acid solution with the concentration of 0.5 mg / L-1.0 mg / L is sprayed into the container filled with the seeds and soaks the seeds for 3-4 hours, then a tray with the seeds is put in a germplasm storage box with the temperature of 0-3 DEG C, refrigeration is performed for 1-3 days, the seeds are taken out, the surfaces of the seeds are covered with wet gauze, the seeds are put in a dark place, and germination is accelerated for 1-2 days, thereby germinating the seeds. The seeds are selected and soaked in the salicylic acid solution, and then the seeds are taken out and refrigerated at the low temperature, so that seed dormancy can be rapidly relieved, and gibberellin and cytokinin in the seeds are sharply increased to promote seed germination; and a growth promoter is sprayed during sowing, seedling lifting fertilizer is applied, and vernalization and cultivation are carried out, so that allium fistulosum breeding can be further promoted, and the breeding time is shortened.

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...
