METHOD OF PREPARING SEEDS OF WATERMELON "ASTRAKHANSKY" FOR SOWING Russian patent published in 2014 - IPC A01C1/00 

FIELD: agriculture.

SUBSTANCE: method comprises isolation of seeds from fruits, preliminary preparation, soaking in the activated water obtained by electroactivation. In the seed-isolating machine the fruits are destroyed, and seeds are separated from the peel, pulp and juice and immersed in a tank with water, equipped with a unit for bubbling and having a temperature of 20-30°C. The seeds are stirred for 0.25-0.50 hours. After switching off the unit for bubbling the full-fledged quality seeds are deposited on the bottom and lightweight seeds floated to the surface are removed with a mesh scoop. The full-fledged quality seeds are then spread in a thin layer of 1.5-2.0 cm on the grid capacity and dried till the complete removal of the water film from the outer surface of the seeds. After that the seeds are immersed in the anolyte solution - electrically activated water with the potential of +500-+600 mV for 0.2-0.5 hours. The seeds treated with anolyte are poured in grid capacity, dried with periodic stirring to commercial moisture regain of 13-14% and packed in hemp or cotton bags for winter storage. 3 days prior to sowing the seeds are soaked in the anolyte - electrically activated water with the potential of +500-+600 mV for 0.20-0.25 hours at a temperature of 15-20°C. After drying with intense aeration for 1 hour at a temperature of 15-20°C the seeds are soaked in the catholyte with the potential of -600- -700 mV and placed on a tarpaulin soaked with catholyte for germination. After the appearance of germs with length of 1-2 mm the germinated seeds are immersed in the catholyte solution with the potential of -600 - -700 mV and sowed with the catholyte using the sowing machine.

EFFECT: avoiding of damage of germs.
