Abstract

FIELD: agriculture. SUBSTANCE: method involves preparing field; providing during 2-3 years protective strips of iris plant with projective cover of 40-60% and spacing width of 50-90 cm; planting rootstock cuttings of mesophytic brake fern in spacings at the rate of one rootstock cutting per 1 sq. m. Plants of iris have rigid belt-shaped leaves protecting brake ferns from wind and incident solar rays. Died-off last year leaves of iris plant serve mulching material. Method allows brake fern to be grown in fields of forest-steppe zones for further usage as medicinal, technical, decorative and food raw material. EFFECT: increased efficiency in growing of forest plants in fields and wider range of use. 3 dwg

Description

 The invention relates to agriculture and can be used for growing mesophytic bracken fern ordinary on fields in the forest, forest-steppe and steppe zones as a medicinal, technical, decorative and food raw material.

 Known methods for growing common bracken in central Russia in the shade of trees with an average annual rainfall of up to 586 mm [1] or other mesophytic ferns in an open sunny area with heavy irrigation, spraying with an average annual rainfall of up to 403 mm [2].

 With an average annual rainfall of 300 mm, open bracken does not grow in open sunny areas.

The proposed method for growing common bracken in the forest, forest-steppe and steppe zones includes preparing the field, planting and growing ferns, in which the field is prepared by growing protective strips of pikeweed up to 70 cm high and projective cover up to 40-60%, and the width between the strips 50-90 cm, bracken are planted with rhizomes at the rate of one rhizome per 1 m ² .

 Figure 1 shows the layout of plants on the field.

 The scheme includes 1 - iris piculica; 2 - bracken.

 In FIG. Figures 2 and 3 show, respectively, the iris species Pikulka 1 and common bracken 2 in a grown form.

Field preparation is carried out using a clean steam system. Then, winter sowing is carried out by the seeder SN-16 (row spacing 50-90 cm) of the seeds of the iris of the piccula at the rate of 20-25 kg / ha. Shoots appear in the spring in the amount of 20-30 pcs./m ² . In the second and third year of cultivation, when the cattle reaches a height of 50-70 cm and the projective cover is 40-60% in early summer, on the SKN-6A universal seedling machine, segments of the bracken rhizomes are planted with sprouted vayas at the rate of one rhizome per 1 m ² . Watering is carried out immediately after planting, as well as 2-4 times as necessary during the growing season.

 Due to the fact that the crops of the iris are hard, thick, belt-shaped leaves, they protect the bracken from the wind and the adverse effects of direct sunlight. Last year's dead leaves of the iris piculia serve as a mulching material, suppress weeds and retain soil moisture.

 Studies in the experimental plot showed: in the first year of fern vegetation, there is a 5-fold increase in the amount of vaya, in the 2nd year, 10 times the initial amount. This indicates that the method can be used in agronomic crops to obtain medicinal, decorative, technical and food raw materials.
