What does the mother of Xanthium use to spread the seed?

Xanthium sibiricum is an annual herbaceous plant, its seeds can extract oil, and the properties of Xanthium sibirica oil are similar to that of tung oil. It can be mixed with tung oil to make paint, can also be used as raw material for ink, soap and linoleum, and can be used as hardening oil and lubricating oil. So, what does the mother of Xanthium use to spread the seed?

First, what does the mother of Xanthium rely on to spread the seed

Xanthium sibiricum spreads seeds by animals. The involucral bracts of this plant have hooked hard spines and are often attached to livestock and human bodies, so they are easy to spread. Widely distributed in Northeast China, North China, East China, Central China, South China, Northwest and Southwest provinces.

II. Main varieties of Xanthium sibiricum

Subunarmed Xanthium: stem shorter, usually branched from base; mature achene involucre smaller, base narrowed, upper end often with a longer beak, and a shorter lateral beak, the two beaks separate or join each other, sometimes the lateral short beak degenerates into spiny or non-existent, the involucre has very sparse spines or few thorns outside the involucre, which can be easily distinguished from Xanthium sibiricum. It often grows on open and dry hillsides, saline-alkali land on the edge of dry fields, dry riverbeds and roadsides. Distributed in Jilin, Hubei, Shanxi, Henan, Hebei, Shandong, Shanxi, Shaanxi, Sichuan, Yunnan, Xinjiang and other provinces.

3. The method of propagation of Xanthium sibiricum

The seeds of Xanthium sibiricum do not require much, just wash the seeds, then air-dry them and then sow them. If it needs to be stored for a period of time, the seeds can be stored in wet sand, but the germination rate of the seeds will gradually decrease. Storage time should not be too long, not only not conducive to germination, but also irregular emergence. Xanthium sibiricum is generally sown and raised seedlings before and after the Mid-Autumn Festival every year, and make a good seedling bed and dig a good seedling ditch before sowing. Then put the seeds in the seedling ditch, apply sufficient basic fertilizer, cover the plastic film, and uncover it when the emergence rate reaches about 80%. About 15 days after emergence, topdressing and watering should be done in time, and field management should be done well. When the seedlings grow to about 65 cm, they can be transplanted and planted.
