COMPLEX FERTILIZING COMPOSITION OF FOLIAR APPLICATION FOR MAIZE CROSS-BREEDING PARCELS

摘要

The invention relates to a fertilizing compositioncomplex for foliar fertilization aof maize plants from hybridization lots.The composition according to the invention contains lOOOgcomposition, 200 g N, under ammoniacal melt,nitric, amide, and amine, 67 g P in formortho, 96g K, 5.7 g S, 2g B, 0.65 g Mo, 2 g Zncomplexed with EDTA, 41 g physiologically organic substancesand surfactants, the composition including adi- and monosubstituted ammonium phosphate buffer systemwhich keeps the pH of the solutions diluted tovalue 7 ± 0,2: the composition is applied in batchesseed (mother) of hybrid seed productionof corn, in the form of solutions with concentrationof 0.5 ... 1%, starting from the phase of 6 ... 8 leaves aplants.The composition, presents as main advantages,increasing the cultural value of hybrid seedcorn and getting some important bonuses onsurface unit at seed productionhybrid, as in the production of grains for consumptionfrom the commercial chains.
