ADAPTIVE TECHNOLOGY OF FLAX OIL APPLICATIONS IN THE DRY ZONE OF NORTH KAZAKHSTAN

Abstract

In the field experiments conducted on the basis of "Akmola-Phoenix" JSC of Tselinograd district of Akmola region (dry steppe zone, dark chestnut soils), the assessment of adaptive capabilities for field germination of plants, including the impact on it by decrease in moisture of the sowing layer (5-6%), increase in sowing density (decrease by 9-17%), the influence of growth stimulants in presowing seeds (increase by 12%). It was found that increasing the density of standing plants reduces the laying of generative organs of plants, but to a lesser extent affects the accumulation of nutrients (the formation of the mass of 1000 seeds). In optimal humidification conditions the ripening period increases which has a positive effect on the formation of productivity. Significant differences in the formation of oil content depending on the use of technological methods were not found, so when sowing on may 20-25, the oil content of seeds increases by 0.4- 0.5%, and when using the growth stimulants increase is 1.1%. For optimum yield in crops sowing on may 20-25 should be formed by the number of plants in the range of 225-250 pcs per m 2 , number of box 18-20 pcs per plant, number of seeds per capsule at the level of 7.5-8 pcs, weight of 1000 seeds is 6.0-6.5g. Seeding flax should be carried out with a seeding rate of 5 million viable seeds per ha for getting maximum yield (10,4-10,5 centner/ha) and oil yield (4,6- 4,7 centner/ha) and profitability of production by 206%. For the formation of the optimal density of the stem (230-250 pcs / m 2) and the optimal number of boxes on the plant (at least 17pcs) the seeds must be processed with Rykat start growth regulator(1 l/t) before sowing. To improve the resistance of plants to drought, improve the development of vegetative and productive parts of the plant to process the tank scheme of drugs Raikat development+Atlanta+Kelik B during the growing season (fir-tree–budding) to increase the number of seeds in the box, the weight of 1000 seeds and increase the oil content of the crop.
