METHOD FOR PREDICTING PRODUCTIVITY OF SAFFLOWER OIL SEEDS

摘要

Method green mass yield prediction safflower comprising stubbling precursor after harvesting, with a turnover plow formation, making the calculated dose of phosphorus-potassium fertilizer plowing, field relief equalization, early spring harrowing, sowing soil at 2 ... 3 ° C in the layer 0- 10 cm and application of nitrogen fertilizer, posleposevnoe compacting and irrigation in the main phenological phases, characterized in that after the appearance of full shoots in terms of the first ten days, and for the next twenty days after the shoot s experimentally establish the vegetative growth of the green mass, and predicted yields of green mass safflower set calculation formula! Q = 0,10 · (M2-M1) · (dN + cai + ebi + αNgN + βqqp + γkqk + f + k) · T,! where Q - yield air-dry weight of safflower to harvesting period t / ha; ! M1 - autonomic weight gain for 10 days after germination, g / m2; ! M2 - autonomic weight gain for 20 days after germination, g / m2; ! d - proportionality factor considering green weight gain when changing standards seeding, d = (97 ... 446) * 10-9 m / pc. germinating seeds; ! N - seeding rate for a given soil and climatic zone, units viable seeds per hectare; ! c - proportionality factor taking into account the influence of the depth of seeding safflower formation of green weight = C (0.833 ... 2.400), m-1; ! ai - actual sowing depth, m; ! e - proportionality factor considering the width between rows on the accumulation of green mass, e = (0.085 ... 0.900), m-1; ! Bi - row spacing, m; ! αN - proportionality factor taking into account the influence of dose on the formation of nitrogen fertilizers vegetative mass
