r ripening, germinate after 22 months, and the first flowering occurs only after 8-10 years;commodity value are ginseng roots weighing not more than 30, at the 20-25 year culture.On the contrary, in a culture with proper preparation of seed germination of their already appears in the first spring;the plants begin to bloom in the third year of life, and commercial value are the roots of a mass of about 25 was already on Thu Wert-fifth year of culture.Ginseng is a shade-loving plant, but not to the same extent as previously thought.It was found that the slow growth and development of ginseng in nature to a large extent are due to insufficient lighting.In addition, it was found that ginseng does not tolerate direct sunlight in the same way as waterlogged soil.

Under natural conditions, ginseng is very rare.It almost completely destroyed during the hundreds of years.Maximum weight of the roots of wild ginseng is 300-400 at the age of 150-200 years, but these roots are found only rarely.Natural ginseng reserves more and more depleted.Ginseng is preserved only in particularly favorable conditions for him, therefore, it belongs to the relict plant.

Agrotehnika growing.Site selection.Ginseng grown in culture or under forest canopy or in open areas.When cultured under its canopy of forest plantations should be located on the slopes of the uncool.It was found that the most favorable for the ginseng, dry deciduous forests, where there are conifers (last pritenyayut ginseng until the leaves).

In open areas ginseng is cultivated exclusively under constant artificial shading using canopies (straw mats, wooden sheds and boards).For this purpose, fertile chosen equal portions.

is best ginseng grows on brown forest soils, well-drained, with plenty of humus layer.

Tillage.Allotted land should be well clear of fallen trees, dead wood and stumps.Thereafter, it is necessary to plow the full depth of the humus layer.

fertilization.By plowing in growing ginseng under forest canopy is made of sheet humus at the rate of 40-60 t / ha.The cultivation of ginseng in the open area beneath the main autumn plowing is recommended to make 100-250 tonnes / ha of compost or leaf compost.On clay soils in conjunction with organic manure should be added to 100-200 t / ha of coarse sand.

reproduction.To preview growing seedlings under the canopy of the forest are assigned the best in fertility and other featured sites in the forest, which is made by digging the forest humus (60 t / ha) with coarse sand (25 t / ha).Before sowing the seeds of the beds in the nursery areas are marked in two directions at a distance of 15x15 or 10x10 cm. In places of crossing sown one seed to a depth of 2-3 cm. After planting hole sprinkle a layer of soil 1.5-3.0 cm. If the appearanceseedling natural shading is insufficient, creating additional artificial shelters using a height of 40-60 cm.

seedlings are planted to a permanent place in the early spring in the hole to a depth of 10-12 cm in the area of ​​food 50X40 cm.

ginseng cultivation in open areas andIt is produced by first growing seedlings.In this case, since the autumn they prepare seedlings beds, in which the seeds are sown before winter ginseng (or spring).On the beds make canopies to shade seedlings.During the summer, as necessary loosen the nurseries, and with the onset of cold weather they are covered with a layer of leaves and shoot the winter shading.Much later remove the shadow and in the southern regions (south of Primorye and the Caucasus).Spring seedlings are planted to a permanent place (also on the beds) in two rows at 5040 cm area of ​​food. Above the beds set sheds 100-120 cm in height on the south side and the north of 120-140 cm.In addition, give the wall to shade the sides to avoid lighting the sun from 9 to 15 hours.

Care plantations is to systematically loosening between the rows, weeding and maintaining the necessary soil moisture (watering).Especially should be watered frequently ginseng in open areas.To ginseng root collar was covered with earth, in the second half of summer ground cover ridges humus thickness 1.0-1.5 cm.

Harvesting.If in vivo harvesting the largest ginseng root is valued the most weight of about 100 g ieold root at the age of about 50 years, in terms of culture roots should be removed on the fourth to eighth year of life.
