Propagation methods of Tibetan hellebore

The propagation methods of Tibetan hellebore mainly include sowing propagation and division propagation. For sowing propagation, the seeds should be soaked in water to accelerate the propagation. The water temperature should not be too high, and the seeds should be taken out and dried in a cool place after slightly swelling. Then evenly spread over the soil to cover the soil and then use shading Mo cover. The method of division propagation requires that in the late summer and early autumn, the rhizome that grows about two flower buds should be cut and transplanted to the prepared soil. Attention should be paid to shading and moisturizing, and the surrounding weeds should be cleaned timely. Now, let's see these two propagation methods of Tibetan hellebore detaily.

Sowing propagation method of Tibetan hellebore

Seed collection and seed treatment

In the middle of May, the seeds were collected in time and dried in the shade when the seed coat changed from green to yellow. The seeds of tibetan hellebore have dormant characteristics, and can be sown in summer immediately after seed collection, or stored dry until the next spring. 

Seedbed preparation and seed handling

Seedling to choose a semi-cloudy and humid environment. The bed surface of seedlings was laid with 3-5cm of sapropelic soil, and the soil was evenly raked and sprayed with 0.5% potassium permanganate solution for disinfection. Soak the spring seeds in warm water at 30-50°C for 2-3 days. 

Sowing

Drill seeding was adopted. When drilling, open 3-5cm shallow trenches on the bed surface, row spacing 15-20cm, sow evenly with mixed sand, cover with 1-2cm of humic soil, and press down on the bed surface after sowing. Drill or broadcast, after sowing to bed cover or shading treatment with 50% of the shading net, often give the bed surface water, keeping the bed surface wet is conducive to the emergence of seeds. 

 Plant division propagation of Tibetan hellebore

Division propagation is one of the propagation methods of Tibetan hellebore. In late summer and early autumn, if there are about two flower buds on the rhizome, then it can be cut for seedling propagation. The buds cut off are vulnerable to resistance. It is necessary to pay attention to shading and moisturizing during propagation to avoid damage to the buds caused by strong light irradiation.

Top dressing is not appropriate after bud transplantation. The absorptive capacity of sprouts is not strong at the early stage of growth, and excessive fertilization will lead to the accumulation of fertilizer and cause the death of root burning and even sprouts. In addition, the surrounding weeds need to be cleaned up to avoid weeds and sprouts competing for water cost, affecting the growth of sprouts.
