Asarum planting technique Asarum planting time and method

Asarum, also known as Xiaoxin, Shaoxin, belongs to aristolochaceae perennial herbs, is a valuable traditional Chinese medicine, has a certain medicinal value, can dispel wind and cold, treatment of headache, cough, rheumatism and other diseases. So how to plant Asarum? Let's learn about the planting method and time of Asarum with the editor.

Planting technique of Asarum

1. Land preparation. Asarum is cultivated under the forest. When preparing the soil, first cut the bottom wood and remove it from the field, then use a rake to pull out stones and other sundries, and then begin to dig the ground. The depth depends on the depth of the soil layer, do not dig out the bottom of the boss, generally 5-20 cm deep. After planing the head again and again with a rake, clear the roots of plants and trees out of the field, hold them flat and then plane them again, dig out the roots of the plants and trees left in the soil, and then you can make a bed. To cultivate Asarum in farmland or garden, first turn the ground (20-30 cm deep), break the soil, apply 2000-3000 kg of pig manure every 667m2, mix the manure into the soil, hold it flat, tidy it up, and then make a bed.

2. Make beds. Asarum border method is simple and easy, along the hillside or slightly inclined with the hillside to do the border, do not Hengshan to do the border, in case Rain Water erosion. General border width 1.2 meters, height 20 centimeters, length can be determined according to the terrain, generally 10-30 meters is appropriate, too long is not easy to flatten, the operating path width 0.8 meters. The soil under the forest is fertile and generally does not apply base fertilizer.

3. Sow seeds. The characteristic of Asarum seeds is that dry seeds are not easy to emerge, so they should be sown while fresh after harvest. Otherwise, the germination ability will gradually decrease with the extension of dry storage time. The experiment shows that the germination rate of fresh seeds can reach 96%, and the germination rate can be reduced to 2% after 60 days of dry storage. Timely sowing is the key to improve the germination rate and ensure the whole seedling. After seed collection, it can be sowed if the soil moisture is good. It is generally carried out from late June to early July, no later than the end of July, otherwise it will affect the long roots.

Planting time and method of Asarum

Seed propagation is the main one, and it can also be propagated by root. Seed propagation: sowing in summer, collecting fruits in early and middle June, stacking them indoors for 1-2 days, removing pericarp, washing seeds and sowing in time after the fruit becomes soft. Do not store dry. Or short-term sand storage, sowing, strip sowing or hole sowing in July. Strip sowing with row spacing of 10-12cm, sowing range of 4-5cm, 120-150 seeds per row, about 60kg seeds per hectare. It can be transplanted 2-3 years after sowing. Split root propagation: leave a root strip at the top of the rhizome. When planting, the holes were opened according to the row distance of 30cm × 20cm, and 2-3 segments of rhizomes were planted in each hole.

Growth habits of Asarum

Asarum is a happy negative plant, most of which are under broad-leaved forests and mixed coniferous and broad-leaved forests with deep humic soil and fertile soil in mountainous areas, or born in dense shrubs, slightly humid places at the bottom of the gully and at the edge of the forest, so it forms a characteristic of like humidity, fertilizer, shade and fear of strong light, but if the canopy is too large under the forest, the growth is very slow. Practice has proved that Asarum can grow quickly and high yield only through "Hua Dayin" or sufficient scattered light and strengthening the management of water and fertilizer.

Classification of Asarum varieties

1. Asarum (original form), often curled into a mass. The rhizome is irregularly cylindrical, with short branches, long 1~250px, 0.2-10px in diameter, gray-brown surface, rough, annular nodes, long 0.2~7.5px internodes and bowl-shaped stem scars at the tip of the branches. The root is slender, dense node, long 10~500px, 2.5px in diameter; the surface is grayish yellow, smooth or longitudinally wrinkled; there are whisker roots and whisker root scars; brittle, easy to break, flat cross section, yellowish white or white. The breath is spicy, spicy and tongue numb.

2. Asarum Seoul (variant), the leaf of this variant has dense short hairs on the back and the petiole is sparsely hairy. Produced in southeastern Liaoning. Born in forests and gully wetlands. It is also distributed in North Korea. The type specimens were collected from Seoul, Korea. This kind of whole herb is used in medicine.

3. Asarum chinense, rhizome length 5~500px, diameter 0.1~5px, Internode length 0.2~25px. The smell is weak.

As mentioned above, Asarum not only has high medicinal value, but also has certain economic value. Planting Asarum has a large output, good quality and a wide range of sales channels, so it can be said that the prospect is relatively broad. Friends who want to start a business to grow medicinal materials might as well try to plant Asarum. Maybe it will bring you a lot of wealth.
