STUDYING OF LONG-TERM CEREAL HERBS FOR BIOLOGICAL REKULTIVATION OF THE BROKEN LANDS IN THE YENISEI NORTH
The paper examines the main stages of growth and development of long-term upstream and downstream of grasses in the tundra zone of the Yenisei North. Germination in the first year (2006 ) at the grassroots grains was 60-63 %, 26-58 % in riding. Over the next 3 years the regrowth of grasses averaged at grassroots cereals 69-71 %, 21-75 % in riding. The largest number of regrown shoots have been among upland crops in brome grade Kenonsky - 1500 pcs./m2, at least brome local - 430 items/m2. The number of shoots grow back from roots of grasses averaged items/m2 3150-4270. Over the years, the number of regrown shoots per unit area in upland grasses decreased, at the grass-roots increased. Observations of the onset of phenological phases shown on the extended period of the passage of tillering. In the first year of life ( 2006), herbs are not moved except for the next phase of the Siberian pyreynika. He reached the phase of stem elongation. During the period of research (2006-2009 years) all reached the grass earing. Flowering stage reached pyreynik Siberian, red fescue, Kentucky bluegrass. Full maturity of seeds fixed at grassroots grains of red fescue and meadow grass in 2009. Over the 4 years of observations from the density of smooth brome grass varieties Antey and Kenonsky increased to 1,383 and 1,650 shoots per 1 m2, with pyreynika Siberian Guran until 1867, meadow fescue and 1150 items/m2. Grass-roots cereals increased their participation in the stand until 4633-6333 shoots per 1 m <sup>2</sup>. Analysis of the data shows that on average, the highest yield of 3-year forms pyreynik Siberian - 15.2 kg / ha, the smallest - Rump Inermis local - 5.5 t / ha. Stable data yields Noting us in riding - crops pyreynika Siberian variety Guran and brome- grade Kenonsky, at the grassroots of grasses: from red fescue - 13.2, in meadow grass - 14.0 c / ha. According to the results of studies concluded that the possibility of use in biological reclamation of disturbed land following species and varieties of herbs horse pyreynik Siberian variety Guran, Rump beardless variety Kenonsky; grassroots red fescue variety Tatiana, mints - face meadow grade Balin.
