METHOD OF INTENSIFICATION OF SPROUTING SEEDS OF RADISH IN PULSE ILLUMINATION

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, namely to plant growing. Method includes pulsed lighting. On 7th day of sprouting in the dark of seeds of radish, sprouts are seasoned with mineral solution of the following composition (mg/l): N-NH₄ – 0.5; P – 4.1; K – 27.5; Ca – 10.0; Mg – 2.4; S – 3.0; Fe – 0.094; Mn – 0.014; B – 0.016; Cu – 0.003; Zn – 0.013; Mo – 0.003. Then light-emitting diode lamps are irradiated at intensity of generated photons of 140 mcmol/m²s at duration of pulses of 1 s illumination and 3 s of pause of darkness, with characteristics of polychrome spectrum: ultraviolet 380 nm – 1.5%, blue 440 nm – 23.8%, green 520-530 nm – 6%, red 640 nm – 61.5%, far red light 740 nm – 7.2% from 7th to Day 14 of round-the-clock illumination of sprouts until production of micro-spawning.;EFFECT: method makes it possible to establish mode of pulsed light-emitting diode lighting in a complex with additional mineral additional fertilizer for increase of productivity and quality of plants in a phase of sprouting of seeds and before the beginning of true photosynthesis.;1 cl, 2 tbl, 1 ex
