Embodiment 1

[0013] 1) Codonopsis pilosula seeds were irradiated with gamma rays, the radiation dose was 0.8 kGy, and the irradiation time was 15 minutes;

[0014] 2) Soak the irradiated Codonopsis pilosula seeds in 30°C water for 5 minutes;

[0015] 3) Soak the above-treated seeds in a calcium chloride solution with a concentration of 3 mM for 12 hours;

[0016] 4) Put the Codonopsis pilosula seeds treated above on the water-soaked gauze, put them in the incubator, and germinate under the light at 28°C, the light intensity is 2000 lux, and the photoperiod is 8 hours. During light germination, the gauze was supplemented with water to keep it moist. Germination began on the 3rd day after treatment, the germination rate reached 93.9% on the 7th day, and the disease incidence rate was 0.23%.

Embodiment 2

[0018] 1) Use gamma rays to irradiate Codonopsis pilosula seeds, the radiation dose is 1.5kGy, and the irradiation time is 10 minutes;

[0019] 2) Soak the irradiated Codonopsis pilosula seeds in 40°C water for 10 minutes;

[0020] 3) Soak the Codonopsis pilosula seeds treated above with 5 mM calcium chloride solution for 24 hours;

[0021] 4) Put the Codonopsis pilosula seeds treated above on the water-soaked gauze, place them in an incubator, and germinate under light at 28°C with a light intensity of 3000 lux and a photoperiod of 12 hours. During light germination, the gauze was supplemented with water to keep it moist. Germination began on the 3rd day of treatment, and the germination rate reached 95.6% on the 7th day. The incidence rate is 0.20%.

Embodiment 3

[0023] 1) Codonopsis pilosula seeds were irradiated with gamma rays, the radiation dose was 2.0kGy, and the irradiation time was 8 minutes;

[0024] 2) Soak the irradiated Codonopsis pilosula seeds in 45°C water for 15 minutes;

[0025] 3) Soak the above-treated Codonopsis pilosula seeds in a calcium chloride solution with a concentration of 10 mM for 36 hours;

[0026] 4) Put the Codonopsis pilosula seeds treated above on the water-soaked gauze, put them in the incubator, and germinate under the light at 28°C, the light intensity is 4000 lux, and the photoperiod is 10 hours. It began to germinate on the third day after treatment, and the germination rate reached 97.3% on the seventh day, and the disease incidence rate was 0.09%.

Abstract

The invention discloses a plant-disease-free insect-pest-free synchronous germination treatment method for Codonopsis pilosula seeds. The plant-disease-free insect-pest-free synchronous germination treatment method comprises: carrying out irradiation treatment on Codonopsis pilosula seeds for 5-60 min at a gamma ray irradiation dose of 0.5-2 kGy, soaking for 1-15 min in 25-65 DEG C water, soakingfor 12-36 h with a calcium chloride solution with a concentration of 3-100 mM, placing on a gauze wetted with water, placing in an incubator, and carrying out illumination germination at a temperatureof 27+ / -3 DEG C, wherein the seeds germinate in the 3rd day after the treatment, the germination peak period is generated in the 5th day, and the germination rate can reach 90-98% in the 7th day, such that the germination rate is substantially increased. With the method of the present invention, the synchronous germination of Codonopsis pilosula seeds can be promoted, the uniformity of seedlingscan be improved, the seedlings grow neatly, the nutrient solution can be used in an unified manner, the greenhouse management operation at the seedling stage is simple and can be conveniently performed by workers, and the incidence rate is 0.05-3% and is far lower than the incidence rate of the seeds treated with the general method.

Description

technical field [0001] The invention relates to a treatment method for Codonopsis pilosula seeds, in particular to a treatment method for Codonopsis pilosula seeds without pests and rapid simultaneous germination, and belongs to the technical field of agricultural economic crop breeding. Background technique [0002] Codonopsis Codonopsis is a perennial herb of Platycodonaceae. The roots are used as medicine. Its main functions are to invigorate qi, invigorate the spleen, promote fluid and quench thirst, and nourish blood. It is mostly used for symptoms such as weakness of the spleen and stomach, lack of appetite in the stomach, fatigue and weakness, chronic illness and weakness, diarrhea, polydipsia and excessive drinking. The growth habit of Codonopsis pilosula likes places with mild climate and cooler summer. According to modern research, Codonopsis pilosula can increase red blood cells, raise blood sugar, promote blood coagulation, lower blood pressure, and improve immu...
