Embodiment 1

[0084] Step 1: Take the ripe fresh seeds of Chonglou dianthus, put them in a cool place to ripen, or mix three parts of wet sand with one part of seeds, ripen for 3-5 days, remove the peel, and wash with water. Mix wet sand with a water content of 70% and seeds 3:1, and place in a refrigerator at 10°C for 1 month;

[0085] Step 2: Take out the seeds and rinse them with clean water, soak them with 100 mg / L GA3 (gibberellin) solution for 2 hours;

[0086] Step 3: Mix wet sand with a water content of 70% and seeds 3:1, place it at 20-22°C, and keep the moisture in the wet sand for 2 months;

[0087] Step 4: Take out the seeds and rinse them with clean water, then soak the seeds in an IAA (auxin) solution with a concentration of 25 mg / L for 2 hours;

[0088] Step 5: Mix wet sand with a water content of 70% and seeds in a ratio of 3:1, then place in a plant growth chamber at 20-22° C., and keep the moisture in the wet sand until seedlings emerge.

Embodiment 2

[0090] Step 1: Take the mature fresh seeds of Chonglou dianthus, place them in a cool place for post-ripening, or mix three parts of wet sand with one part of seeds, post-ripen for 5 days, remove the peel, wash with water, and use wet sand with a water content of 65% Mix with seeds 2.5:1, place in refrigerator at 11°C for 28 days;

[0091] Step 2: Take out the seeds and rinse them with clean water, soak the seeds with 200mg / L GA3 (gibberellin) solution for 2 hours;

[0092] Step 3: Mix wet sand with a water content of 70% and seeds 3:1, place it at 20°C, and keep the moisture of the wet sand for 58 days;

[0093] Step 4: Take out the seeds and rinse them with clean water, then soak the seeds in an IAA (auxin) solution with a concentration of 25 mg / L for 2.5 hours;

[0094] Step 5: Mix wet sand with a water content of 70% and seeds at a ratio of 2.5:1, then place in a plant growth chamber at 20° C., and keep the moisture in the wet sand until seedlings emerge.

Abstract

The invention discloses a method for sprouting seeds of polyphylla Smith var.ynynanensis (Franch.) Hand-Mazz, comprising the following steps: mixing wet sand with water content of 60-80% with the seeds of polyphylla Smith var.ynynanensis (Franch.) Hand-Mazz in a ratio of 2-4:1 and placing the mixture under the temperature of 8-15 DEG C for 25-35d; taking out the seeds and soaking the seeds in 50-200mg / L of GA3 solution for 1.5-2.5h; then mixing the wet sand with water content of 60-80% with the seeds in a ratio of 2-4:1, placing the mixture under 18-25 DEG C and keeping the moisture of the wet sand for 55-70d; taking out the seeds and soaking the seeds in 2.5-30mg / L of IAA solution for 1.5-3h; and mixing the wet sand with water content of 60-80% with the seeds in a ratio of 2-4:1, placing the mixture into a plant growing chamber at 20-22 DEG C and keeping the moisture of the wet sand. The method can ensure the seeds of polyphylla Smith var.ynynanensis (Franch.) Hand-Mazz to sprout ahead of time and have high emergence rate.

Description

technical field [0001] The invention relates to a method for accelerating the germination of seeds, in particular to a method for accelerating the germination of the seeds of Pachyphytum dianthus. Background technique [0002] Paris plant belongs to Trilliaceae Trilliaceae Paris plant, mainly distributed in the southwest of China. Due to the widest distribution in Yunnan and the highest medicinal value, Dianzhonglou was recorded in the 1995 and 2000 editions of the Chinese Pharmacopoeia, and its scientific name is Paris polyphylla Smith var.yunnanensis (Franch.) Hand-Mazz. Traditional Chinese medicine believes that this product is bitter in taste, slightly cold in nature, slightly poisonous, and returns to the liver meridian. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain, cooling liver and relieving convulsions. It is often used for furuncle redness, sore throat, poisonous snake bites, bruises, convulsions and convulsions...
