Problems solved by technology

[0003] The present invention is aimed at the existing problems: my country's saline-alkali land has reached 99.1 million hectares, realizing the control and utilization of saline-alkali land is an important way to alleviate the problem of food shortage; peanuts have strong drought resistance, but their soil salt tolerance is relatively low. Poor; while using radiation or chemical mutagenesis methods to directly mutate peanuts, the direction of mutagenesis is uncertain, and the probability of the obtained mutagenized seeds having salt-alkaline tolerance is small

Embodiment 1

[0019] A breeding method for salt-alkali-tolerant peanuts, comprising the following steps:

[0020] (1) Storage: Spray peanuts with abectin solution, mix the sprayed peanuts with organic fertilizers and store them at a temperature of 1.5°C for 23 days. Absorb and utilize, improve the stress resistance of the seeds, and then raise the temperature to 24°C and let it stand for 4.5 hours to store peanuts;

[0021] (2) Sealing treatment: Put the stored peanuts into a closed container and pass ethylene gas first, which can improve the maturity and cell activity of the peanuts, raise the temperature to 36°C and store it for 4.5 hours, discharge the ethylene and then pass it into the closed container Ozone, which has the effect of improving the stress resistance and activity of peanuts, is cooled to 28°C and stored for 2.5 hours to process peanuts;

[0022] (3) Ultraviolet mutagenesis: Put the processed peanuts into a vacuum tank and evacuate to 86%, then pass atomized saline with a ...

Embodiment 2

[0032] (1) Storage: Spray the peanuts with abectin solution, mix the sprayed peanuts with organic fertilizers and store them at a temperature of 2.5°C for 27 days. Absorb and utilize, improve the stress resistance of the seeds, and then raise the temperature to 25°C and let it stand for 5.5 hours to store peanuts;

[0033] (2) Sealing treatment: Put the stored peanuts into a closed container and pass through ethylene gas first, which can improve the peanut maturity and cell activity, raise the temperature to 37°C and store it for 5 hours, discharge ethylene and then pass ozone into the closed container , which has the effect of improving the stress resistance and activity of peanuts, cooling down to 29°C and standing for 3 hours to process peanuts;

[0034] (3) Ultraviolet mutagenesis: Put the processed peanuts into a vacuum tank to evacuate to 89%, then pass atomized saline with a mass concentration of 0.4%, 0.78%, and 1.2% into it, and heat up to 43°C for use The light inte...

Abstract

The invention discloses a breeding method for saline-alkali-resistant peanuts, which is characterized in that it includes the following aspects: (1) storage, spraying peanuts with abectin solution, and mixing the sprayed peanuts with organic fertilizers Low-temperature storage; (2) Sealing treatment, put the stored peanuts in a closed container and first pass ethylene gas into the airtight container for storage, discharge ethylene and then pass ozone into the airtight container for storage; (3) Ultraviolet mutagenesis, put the processed peanuts in (4) pressurized mutagenesis, soaking the ultraviolet mutagenized peanuts in saline for mutagenesis treatment; (5) germination treatment, pressurized mutagenic peanuts placed at constant temperature When the buds are germinated in the box until the buds and leaves are slightly leaking, then use the tobacco leaf extract to smear the buds and leaves twice; (6) Greenhouse cultivation, sow the germinated peanuts to the greenhouse seedling bed for cultivation, plant well-growing plants separately and collect seeds .

Description

technical field [0001] The invention belongs to the technical field of peanut breeding, and in particular relates to a breeding method for salt-alkali-tolerant peanuts. Background technique [0002] Saline-alkali land is the soil where salts are relatively concentrated, and the salt content in the soil is between 1 / 1000 and 6 / 1000. The excessively high salt content affects the germination and normal growth of plant seeds, and the salt content in the soil is below 3 / 1000. The germination rate of seeds can only reach 70%-80%, and the salinity content in heavy saline-alkaline soil exceeds 6 / 1000, and the germination rate is lower than 50%, which may even cause the soil to be unable to grow plants; with the continuous increase of the world population, the area of ​​agricultural land is shrinking , the global grain and oil shortage is becoming more and more serious, and the saline-alkali land in the world has reached 950 million hectares, of which the saline-alkali land in my count...
