Problems solved by technology

[0005] After sowing in spring, frequent irrigation and shading are required to keep the soil moist. At the same time, there are substances that induce seed dormancy in the mature seeds. The seeds need to be kept under the above conditions for 30 days before they can germinate in the soil. Otherwise, the seeds cannot germinate in the soil or are killed by drought stress. The germination rate and emergence rate are low, and the germination growth season overlaps with the weed germination growth season, so weeding must be repeated many times, which increases the difficulty of field management and production costs of Dauri gentian seedlings

Embodiment 1

[0055] The processing method of dauri gentian seed, comprises the following steps:

[0056] (1) Seed storage: vacuum seal the seeds after drying, freeze and store below -18°C, and dry the seeds until the water content is 12%;

[0057] (2) Sieving: On the second day before sowing, take out the frozen and stored seeds in step (1), and sieve to obtain plump and free seeds;

[0058] (3) Release dormancy: wash the seeds screened in step (2), then soak them in water for 2 hours, and finally soak them in a mixed solution of gibberellins and humic acid for 12 hours, and set aside, the concentration of gibberellins is 400ppm , the mass concentration of humic acid is 0.005%;

[0059] (4) Coating: put the seeds released from dormancy in step (3) into the coating machine for coating, the speed of the coating machine is 30r / min, add the antibacterial agent, water retaining agent, and red clay powder into the coating machine Spray water into the seed coating, add repellent after the coati...

Embodiment 2

[0072] The processing method of dauri gentian seed, comprises the following steps:

[0073] (1) Seed storage: vacuum seal the seeds after drying, freeze and store below -18°C, and dry the seeds until the water content is 12.4%;

[0074] (2) Sieving: On the second day before sowing, take out the frozen and stored seeds in step (1), and sieve to obtain plump and free seeds;

[0075] (3) Relieve dormancy: wash the seeds screened in step (2), then soak in water for 3 hours, and finally soak in a mixed solution of gibberellin and humic acid for 20 hours, and set aside, the concentration of gibberellin is 500ppm , the mass concentration of humic acid is 0.01%;

Abstract

The invention discloses a treatment method, artificial planting and a wild tending method of gentiana dahurica seeds. The treatment method comprises the steps of: after drying the seeds, carrying outvacuum sealing on the seeds and carrying out frozen storage below minus 18 DEG C; two to five days before sowing, taking out the seeds subjected to frozen storage, and sieving to obtain full and non-impurity seeds; and carrying out water washing on the sieved seeds, then soaking the seeds in water for 2 to 4h, finally, soaking the seeds in mixed solution of gibberellins and humic acid for 12 to 36h, placing the obtained seeds into a coating machine to carry out coating, sequentially adding a bacteriostatic agent, a water-retaining agent and red clay powder into the coating machine, spraying clear water to carry out seed coating, after coating is completed, adding a repellent, carrying out uniform mixing, placing the obtained product in the room to carry out ventilation drying, and carryingout air-drying until water content is 30 to 50%. According to the treatment method, the artificial planting and the wild tending method of the gentiana dahurica seeds, which are disclosed by the invention, the modern agricultural technology is applied, mechanization is introduced, production efficiency and a standardization level of gentiana dahurica medicinal material production are improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medicinal material planting, and more specifically relates to a treatment method, artificial planting and wild tending method of Dauri gentian seeds. Background technique [0002] Gentianadahurica Fischer, also known as Gentianadahurica Fischer, is one of the basic medicinal materials of Gentianadahurica Fischer stipulated in the 2015 edition of the Pharmacopoeia of the People's Republic of China. , low fever and other diseases; flowers into Mongolian medicine, can clear the lungs, relieve cough and detoxify. [0003] Dauri gentian is a perennial herb, distributed in Sichuan, Northwest, North China, Northeast and other places. It grows in river beach sandy land, ditch side, sunny hillside and dry grassland. It is suitable for hilly mountainous areas with gravel soil at an altitude of 870-4500 meters. . Prefers shade at the seedling stage, afraid of drought, afraid of sun burns, drought-resistant after a...
