Planting techniques of Asarum

Asarum is a commonly used Chinese herbal medicine, which has the effects of relieving pain, dispelling wind and dispelling cold, and is deeply loved by doctors for the treatment of headache, cough, rheumatism and other diseases. With the expansion of market demand and the rise of artificial cultivation of Asarum, now there are a large number of cultivation in Liaoning, Jilin, Heilongjiang and other places in China. Let's take a look at the planting techniques of Asarum.

1. Land selection and preparation

Asarum generally grows coniferous forest and broad-leaved forest, so it can be cultivated under the forest, and the soil requirement is humus loam with deep soil layer. You can also choose farmland cultivation, farmland cultivation requires loose, fertile, well-drained sandy soil, avoid low-lying, sticky, fertilizer-poor soil. In the cultivation under the forest, the trees that are too dense should be cut down, and then the roots should be cleared, ploughed and leveled to make a high bed, while the farmland should be leveled and raked fine, making a high bed.

2. Sowing seeds

The seeds must be sown with picking, lest the seeds fall off naturally and cause losses. after picking the fruit, put it in a dark environment for 1-2 days, soften the fruit, rub off the peel, rinse with clean water, and sow after a little drying. If the seeds are not sown in time, the seeds can be buried in the wet sand and taken out when sowing. Sowing can be used to sow a strip sowing method, sowing seeds evenly on the seedling bed, covering a layer of fine soil, and then covered with a layer of deciduous leaves or straw, heat preservation and moisturizing, in the second year, sowing is generally 10 kg per mu. Strip sowing is ditching in the seedbed, generally 5-6cm wide and 3-5cm deep, and the bottom of the ditch should be leveled and compacted. After sowing in the ditch, it is covered with a layer of shallow soil, also covered with deciduous leaves or straw, and removed the following year, generally 6-7 kg.

3. Seedling stage management

The soil should be kept moist after sowing, watered when dry, drained when overcast and rainy, to prevent stagnant water from causing rotten seeds, and when thawed in the spring of next year, the mulch should be removed in time to raise the ground temperature, speed up seedling emergence, and pull out weeds, while forest cultivation should straighten out the crown and increase light. Starting from the third year, it is necessary to top fertilize once every year when overwintering, generally using rotten farm manure or fallen leaves in the forest.

4. Transplanting

Asarum is a perennial plant, the growth and development cycle is very long, generally 6 years after sowing will blossom and bear fruit, so generally in artificial planting will use wild seedlings transplanting to expand the planting area. Sowing and transplanting can be carried out in autumn and spring, and transplanting in spring should be carried out before spores germinate, otherwise Asarum has begun to emerge or spread its leaves, and transplanting needs a lot of watering and slow seedling period for a long time, which is disadvantageous to the growth and development of Asarum. In autumn, Asarum was transplanted in October, and Asarum was dug and grown for 2-3 years, and planted according to plant size. When planting, the root system should be spread out in the hole, and reasonable close planting.

5. Field management

After transplanting, it is necessary to strengthen the management, loosen the soil and weed 3-4 times a year, increase the soil temperature, conserve water, control diseases and promote its growth. In addition, fertilization is also essential, topdressing 2-3 times a year, the first time in January, the application of ammonium sulfate 5-7.5kg per mu, the second application of farm manure 3000-4000 kg per mu. Forest cultivation should regularly clear the forest, lest the branches are too dense and lead to lack of light in the forest, while the farmland should build a sunshade to adjust the light.
