METHOD FOR CULTIVATION OF HAY CROP FOR GREEN FEED UNDER IRRIGATION CONDITIONS AND APPARATUS FOR INTRODUCING OF BISCHOFITE SOLUTION Russian patent published in 2006 - IPC A01B79/02 A01D43/08 

FIELD: agriculture.

SUBSTANCE: method involves simultaneously sowing cover crop, preferably winter wheat or winter rye, or winter barley and perennial grasses; before sowing, introducing weed controlling chemicals, preferably soil herbicides, for producing of pure sprouts; introducing mineral fertilizers, with type of soil and programmed (planned) grass yield for green mass being taken into account; providing harvesting of eye part of winter wheat, winter rye or winter barley at high cut by direct combining; distributing non-grain part in the form of small-sized chaff on field surface; simultaneously with distribution of non-grain part of precursor, applying solution of natural bischofite mineral of Mg Cl₂ 6H₂O formulation onto precursor stubble and onto leaf and stalk mass of perennial grasses at application norm of 150-450 l/hectare and density of 1.2-1.3 t/m³ . On applying solution of natural bischofite mineral, foliar feeding of perennial grasses is provided; on mowing of grasses green mass is saturated with feeding microelements of bischofite solution and pathogenic microorganisms are controlled. After vegetative irrigation, content of microelements in green mass is increased through root system and nutrient value of grass mixture is increased. Apparatus for applying of liquid additives, such as solution of natural bischofite mineral, into mass harvested by combine has silage guide, reservoir, pump connected through pipe to sprayer, and mass sensor connected with feeding actuating device. Set of sprayers are mounted on bar rearward of carrier bar of combine header. Sprayers are alternatively inclined to the left and to the right toward axis of symmetry of bar. Inclined casing of header chamber serves as mass sensor. Casing of inclined chamber is kinematically connected with spherical valve, which is in fluid communication through pipe with pump and flexible hose equipped with bar.

EFFECT: uniform distribution of solution of natural bischofite mineral on surface of perennial grasses.
