NANOSTRUCTURED AQUEOUS PHOSPHORITE SUSPENSION AS CUCUMBER SEED PRESOWING TREATMENT AGENT

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to production of biologically active substances which stimulate plant growth and can be used in agriculture. The nanostructured aqueous phosphorite suspension consists of nanoparticles smaller than 100 nm. Said agent is obtained from natural phosphorites by grinding, mixing with water and ultrasonic dispergation.;EFFECT: use of the invention increases cucumber yield during the first month of harvesting 2,0-2,5-fold.;19 ex, 2 tbl
