Sown cannabis is an annual two-house plant.
The hemp root is rooted, sativa delivery to a depth of 1.5-2 m. The bulk of the roots develop in a layer of up to 40 cm. The roots are 2-3 times smaller in weight than the roots of the mother.
The stem is straight, simple, less often branchy, rounded at the bottom, hexagonal and grooved at the top, covered with glandular hairs. Usually it reaches 1½ m in height, and in some species it is much higher, so in var. chinensis (Chinese hemp) it reaches 3-6 m.
Leaves are long-petioled, lower ones are laptic-complex, with 5-7 (rarely 9) narrow dentate leaves along edges; upper ones are triple-blade or whole. The internodes are long. Lower leaves are arranged serpentine, upper ones alternately. Two free stinisles are developed on a leaf.
Hemp flowering is sown (in contrast to the widespread wild Cannabis ruderalis) and starts later in August-September. The signal to start flowering is a significant extension of the dark time.
Flowers are of the same sex; the plant is binary, male plants flower a little earlier. Sprayed by the wind.
Male inflorescences (complex brushes or brooms) are placed on side branches or at the top of the stem; female compressed-colonoid inflorescences develop in the leaf sinus. Female flowers are of the fifth type, greenish-yellow, with five stamens carrying long anthers with plenty of pollen.
Female flowers consist of a one-leaved cover, a pestle with a one-strand ovary and two thread-shaped pinnacles.
the germ is bent, the seed is protein-free.
The fruit is a bivalve of light grey coloured nut, often with a mosaic pattern. The diameter of the fetus is 2-5 mm. Weight of 1000 seeds 9-22 g.
Often found wild in weedy places. Wild (or wild) form is often considered as a separate botanical species - weed (Cannabis ruderalis Janisch.).
It is the ancestor of most of the cannabis varieties currently grown (mainly hybrids with Cannabis indica), many of which are medicinal.
wn hemp varieties for sowing (not hybrids with Indian hemp):
Mexican (Acapulco gold, Oaxacan, Zacatecas Purple, Guerrero Gold, Michoacan).
Brazillian (Manga Rosa, Santa Maria)
Colombian (Colombian Red, Santa Marta Colombian Gold)
African (Durban, Swazi, Power Plant, Congolese, Malawi Gold, Angolese, Lesothan, Nigerian)

Hemp seeds contain 30-38% fatty oil, consisting mainly of unsaturated fatty acid glycerides (linoleic, linolenic and oil). Proteins, amino acids (glycol, alanine, valine, leucine, isoleucine, phenylalanine, threonine, tyrosine, aspartic acid, trigonelline, oxyproline, etc.), carbohydrates, quebracht alcohol, phenolic compounds (cannabinol and cannabidiol), and traces of alkaloids were also found .
The hemp comes from Central and Western Asia, and by the beginning of the 20th century it was already cultivated everywhere for the sake of bast fibers. In crops, the number of male and female plants is approximately the same. In comparison with the mother, the plant is thinner, less lined and ripens earlier. Therefore, their share in the harvest is different. Skoon gives no more than 33, and cloth - 66% of the total yield of fibers. Fiber goes on ropes, twine, ropes, radish, canvas, antimony, sacking.
In the 60s of XX century hemp occupied the 3rd place among spinning plants after cotton and flax.
Waste spinning production - bag - is used for hemp digging, packaging.
Cake (but not green mass) is used for cattle fodder. Freshly cut hemp grass causes severe poisoning in cattle, especially horses.
The seeds contain oil, which is used for food and paints.
The ancient Greeks prepared from the seeds a special drink called νηπενθής (literally - quenching suffering).
Medicine uses dried fruit-bearing tops of https://chikymiky.com/product-category/sativa/ female flower branches of plants or leaves, as well as potion and herbal extract.
Straw is valued as a bedding for livestock because it absorbs moisture well.
Nowadays, hemp has gained popularity as a source of the common so-called "light drug", so its cultivation is now controlled and wild growths are destroyed.
