TECHNIQUE AND TECHNOLOGY OF SURFACE IMPROVEMENT OF FLOODPLAIN MEADOWS OF THE REPUBLIC OF TATARSTAN

Research with the aim of developing and implementing highly effective methods surface improvement floodplain meadows partial preservation old herbage sowing new perennial grasses based on widespread use modern integrated agricultural machines implements was carried out in 2016-2020 Republic Tatarstan. The scheme experiment included following options: processing sod meadow (factor A) – without processing; disking BDN 4 ×4 + flat-cutting to a depth 22 ...24 cm KPG-2-150; universal cultivator-planar cutter piercing action harrows (KPU-5,4) Perm Machine-Building Plant; equipped perforating harrow (KPBL-3) Kazan State Agrarian University design; mineral fertilizers B) fertilizers; alfalfa-stalk grass mixture at rate 12 kg/ha (6 million pcs/ha germinating seeds) combination annual application spring N45P20K45. control natural stand processing, applying fertilizers. results research have shown high efficiency complex agrotechnical techniques: layer-by-layer tillage using cultivator-planer (KPBL-3), seeds fertilizing At same time, yield green mass increases by 2.74 times compared original herbage, profitability feed production is 73.6%, cost price reduced 6910 rubles. selling for 1000 units, 12,000 total energy costs increase from 18.4 variant 21.6 GJ/ha, however, accumulation exchange outstrips these 3.2 times.
