Sexual reproduction of Asarum

Both strip sowing and sowing are possible for sexual reproduction, and sowing is better. When the seeds were first collected, the germination rate reached 96%, dry for 20 days, 81% for 40 days, 29% for 60 days, and only 2% for 60 days. Therefore, after the seeds are ripe and harvested from June to July, they should be sown immediately. For some reason, the seeds could not be sown. After mixing 3 parts of wet sand and 1 part of seeds evenly, they were buried in the shade to maintain proper humidity, but the seeds could not be sowed later than the end of July at the latest, which would affect the long roots. About 5kg of fresh seeds are needed per mu.

Seeding is often used to raise seedlings in the forest. Because of its loose and fertile soil, the seeds are easy to emerge, and the seedlings are evenly distributed, which is conducive to root growth. Remove 3-5cm from the bed before sowing, flatten the bottom of the border with an iron rake, mix the seeds with 5-10 times fine sand or fine humus, evenly remove on the trough surface, the distance between seeds is 1-2cm, and then cover 1-1.5cm with sifted fine humus. The bed is covered with a layer of firewood or leaves to preserve moisture and prevent erosion by Rain Water. The sowing amount is 15g/ square meters.

Strip sowing on the bed is laterally spaced 10cm, 5-6cm wide. In a flat-bottomed shallow trench with deep 3cm or so, spread the seeds evenly into the ditch (seed spacing 1-2cm, sowing rate 12-15g/ square meters;), cover 1-1.5cm with sifted fine humus soil, step on your feet, water them, and cover with a layer of firewood or leaves to preserve moisture after 2-3 days.

Asarum can not take root in that year after sowing, and the mulch should be removed in time before emergence in the spring of the second year to facilitate seedling emergence.

The transplanting seedlings were cultivated for 2-3 years and then transplanted. It can be planted in spring and autumn, but it is better to plant in autumn. After the leaves fade in autumn and before the buds germinate in spring, select strong seedlings with complete roots free of diseases and insect pests. Cluster planting was carried out in a trench with a distance of 15-20cm and a depth of 9-10cm on a prepared seedbed. Cluster spacing 8-10cm, 3-4 seedlings per clump, 2-3 large seedlings, bud head away, slightly raised, the root is fan-shaped stretch; if the soil is dry, need watering, after water infiltration, cover soil 7-8cm (field transplanting cover soil can be shallow), slightly suppress. After autumn planting, the border is covered with dead branches and leaves to prevent Rain Water from scouring or soil consolidation. If transplanting in early spring, a shade should be built. Rhizome propagation is often carried out in combination with drug collection. After the Asarum was dug out, most of the rhizomes and fibrous roots were processed into medicine, and the full and robust rhizomes with terminal buds were selected and planted with 4-5cm, 2-3 buds and 15-20 fibrous roots.
