Problems solved by technology

[0005] The invention aims to solve the technical problem that after the licorice seeds are treated with sulfuric acid, the seed coat becomes thinner and the water absorption speed is accelerated, which easily leads to damage to the seeds by imbibition, cold damage from imbibition, and adversity hazards such as saline-alkali, pests and other adversities, which lead to a decrease in seed vitality, and provides A method for licorice seed medicinal sand priming that can significantly improve the vigor of licorice seeds and stress resistance of seedlings, promote seed germination and seedling growth, and has the advantages of cold resistance, disease resistance, full seedlings, strong seedlings, and improving seedling quality

Embodiment 1

[0027] The method that a kind of licorice seed medicine sand of present embodiment initiates, carries out according to the following steps:

[0028] 1. Use ordinary sulfuric acid treatment method to break the hardness of Ural licorice seeds: treat 1.2kg of neat licorice seeds with 100g 80% concentrated sulfuric acid at 25°C for 5 hours, rinse 5 times with distilled water, absorb excess water with filter paper, and dry in the air. Dried to obtain hard licorice seeds;

[0029] 2. River sand pretreatment: wash the river sand and pass it through a 0.8mm sieve, and then disinfect it at 143°C for 2 hours;

[0030] 3. Preparation of medicament: configure a salicylic acid solution with a concentration of 0.0016%;

[0031] 4. Preparation of medicinal sand: mix 1.7kg of river sand pretreated in step 2 with 100ml of salicylic acid solution prepared in step 3, and then let it stand for 1 hour to obtain medicinal sand;

[0032] 5. Treatment: Mix 5kg of licorice seeds that have been remov...

Embodiment 2

[0036] The method that a kind of licorice seed medicine sand of present embodiment initiates, carries out according to the following steps:

[0037] One, use foam acid treatment to break the hardness of Glycyrrhiza Uralica seeds: first, clean and select Glycyrrhiza Uralica seeds, so that the purity of the seeds reaches 99.9%; add 0.1g sulfonic acid to 99.9g 80% sulfuric acid, stand for 2h, and prepare To obtain foam acid; mix 1.2kg licorice seeds with 100g of prepared foam acid, and stir for 3 minutes; put the seeds mixed with foam acid into a pool covered with plastic film, and treat at 15°C for 6 hours; during this period, turn over every 1.5h Once; rinse the treated seeds with a high-pressure water gun with a pressure of 0.6 MPa for 1 min, dry the water, and dry in a cool and ventilated place to obtain licorice seeds that have been treated with foam acid to remove the hardness;

[0038] 2. River sand pretreatment: wash the river sand and pass it through a 0.6mm sieve, and t...

Embodiment 3

[0045] The method that a kind of licorice seed medicine sand of present embodiment initiates, carries out according to the following steps:

[0046]1. Use foam acid treatment to break the hardness of Glycyrrhiza glabra seeds: first, clean and select the seeds of Glycyrrhiza glabra so that the seed clarity reaches 99.9%; add 0.1g of sulfonic acid to 99.9g of 80% sulfuric acid, and let it stand for 2 hours , to prepare foam acid; mix 1.2kg licorice seeds with 100g of prepared foam acid, and stir for 3min; put the seeds mixed with foam acid into a pool covered with plastic film, and treat at 15°C for 6h; during this period, every 1.5h Turn it over once; wash the treated seeds with a high-pressure water gun with a pressure of 0.6 MPa for 1 minute, shake off the water, and dry them in a cool and ventilated place to obtain licorice seeds that have been treated with foam acid to break the firmness;

[0047] 2. River sand pretreatment: wash the river sand and pass it through a 0.05mm ...

Abstract

The invention relates to a medicine sand priming method for licorice root seeds, and relates to a method for processing seeds before sowing. The invention aims to provide a medicine sand priming method for the licorice root seeds, which has the advantages that the licorice root seed vigor and the stress resistance of seedlings can be obviously improved, the seed germination and the seedling growth are promoted, cold resistance and disease resistance are achieved, and the seedling quality is improved. The medicine sand priming method for the licorice root seeds provided by the invention comprises the following main steps: eradicating the hardness of the licorice root seeds; preprocessing river sand; preparing a medicament; preparing medicine sand; processing the seeds with the medicine sand; cleaning; and drying in the shade. The medicine sand priming method for the licorice root seeds provided by the invention is high in speed of germination and high in vigor; the surface is rough, so that seed pelleting is facilitated; the volume becomes large, and the seeding quantity is reduced; the resistances of the seed germination and the seedling growth to adverse situations of dryness, salt and alkali, cold damage, imbibition damage, imbibition cold damage and the like are improved; the field seedling rate under the adverse situations is improved. The method is used for the fields of production, processing and artificial cultivation of the licorice root seeds.

Description

technical field [0001] The invention relates to a method for treating seeds before sowing, in particular to a method for treating licorice seeds before sowing. Background technique [0002] Seed priming, also known as "osmotic conditioning", was proposed by Heydecker et al. It is a seed treatment technology that controls the slow water absorption and gradual drying of seeds. This technology has been successfully applied to many plant species, and sand-triggered rice, sweet corn, alfalfa, turfgrass, soybean, etc. have remarkable effects in improving seed vigor and seedling resistance physiological research. Both salicylic acid and 5-aminolevulinic acid solution are low-cost high-molecular chemical substances with the characteristics of plant hormones. Applying salicylic acid to seeds can significantly improve the resistance of seed germination and seedling growth to chilling damage and salinity. Tolerance, and at the same time have a significant effect on strong seedlings an...
