Embodiment 1

[0023] (1) Harvest mature wild hemp seeds in Northeast China, thresh, remove impurities, and store them in the room at room temperature for 6 months after drying. Select plump and undamaged wild hemp seeds.

[0024] (2) Use the selected seeds with 1% H 2 o 2 Soak the aqueous solution at room temperature for 5 hours, take it out and rinse it with sterile water for 3 to 5 times, the soaking ratio is: use 200ml of diluted H for every 100g of seeds 2 o 2 aqueous solution.

[0025] (3) Bury the seeds treated in step 2 in wet sand at a temperature of 4°C, and add a small amount of water every 6 to 7 days to keep the absolute water content of the sand layer at 5 to 10%.

[0026] (4) After 20 days of cold-wet stratification treatment, remove the sand and rinse with sterile water for 3 to 5 times; take a clean petri dish with a diameter of 12 cm as a germination bed, and use double-layer filter paper germination method for germination culture. After the seeds in the bed are moisten...

Embodiment 2

[0028] (1) Harvest the mature wild hemp seeds in Yunnan, thresh, remove impurities, and store them in the room at room temperature for 30 days after drying. Select plump and undamaged wild hemp seeds.

[0029] (2) Use the selected seeds with 0.1%, 0.5%, 1% H 2 o 2 Soak the aqueous solution at room temperature for 5 or 24 hours, take it out and rinse it with sterile water for 3 to 5 times, the soaking ratio is: use 200 ml of diluted H for every 100 grams of seeds 2 o 2 aqueous solution.

[0030] (3) Bury the seeds treated in step 2 in wet sand at a temperature of 6°C. From the 7th day, observe whether the seeds have cracks, and observe once every other day. When the seeds are observed to have 40-50% of the seeds Split, and the radicle is exposed (that is, Lubai) for the next step of germination culture. During the treatment period, add a small amount of water every 6-7 days to keep the absolute water content of the sand layer at 5-10%.

[0031] (4) Remove the sand and rins...

Embodiment 3

[0035] The difference from Example 1 is that:

[0036] The cold-wet stratification treatment was: -20, 1, 4, 6°C for 20 days or -20°C for 7 days and then 4°C for 13 days. The germination results are shown in Table 2.

Abstract

The invention discloses a method for improving the germination rate of wild hemp seeds. According to the method, firstly, the wild hemp seeds are finely selected, then, the reagent pretreatment and the cold wet lamination treatment are carried out, and finally, sprouting or sowing is carried out. The germination rate of the wild hemp seeds is improved for higher than 70 percent for the first time, addition, the sprouting and the germinating are regular, the quality of growing seedlings is high, the problem that the wild hemp seeds cannot be germinated under the ordinary condition or the germinating rate is extremely low is solved, the method belongs to the key technology breaking of resource storage and protection of the wild hemp seeds, and meanwhile, the foundation is laid for the industrial hemp seed breeding study and the mild hemp seed resource development and utilization. The application range of the method is wide, the wild hemps in different distribution regions can be covered, the influence caused by external climatic factors is little, and the method can be implemented in the whole year. The treatment time is short and is ordinarily 8 to 20 days. The treatment process and the treated seed have no any toxic or side effect, no danger is generated on seed contactors, and the environment pollution cannot be caused. The method has the advantages that the treatment process is simple, the cost is low, the operation is easy, the batch treatment is realized, and the like.

Description

technical field [0001] The invention belongs to the technical field of plant seed germination, and in particular relates to a method capable of effectively improving the germination rate of wild hemp seeds. Background technique [0002] Hemp (Cannabis sativa L.) is one of the oldest cultivated crops in the world. It has strong adaptability to the environment and is widely distributed in tropical and frigid regions. Now hemp has developed into a multi-purpose crop, which is widely used in modern textiles, papermaking, edible oil, functional health food, cosmetics, medicine, bio-energy, building materials, new bio-composite materials and other industries. Internationally, the type of cannabis that contains less than 0.3% (percentage of dry matter of flower spikes of the female plant) and does not have the value of drug utilization is called industrial hemp. Due to the high economic development and utilization value of industrial hemp, and various advantages in ecological prot...
