METHOD OF NATURAL FORAGE STOCK INTENSIFICATION IN FISH FARMING PONDS

摘要

FIELD: agriculture.;SUBSTANCE: method of natural forage stock intensification in fish farming ponds relates to pond fish farming and can be applied in stimulation of phyto and zoo plankton growth in fish farming ponds. Method involves addition of fertiliser in amount of 25-35 kg/ha of ammonium nitrate, 15-25 kg/ha of potassium monophosphate and 30-40 kg/ha of potassium chloride immediately after pond filling, and repeated addition of fertiliser in amount of 40-60 kg/ha of ammonium nitrate, 15-25 kg/ha of potassium monophosphate and 10-20 kg/ha of potassium chloride over 14-20 days.;EFFECT: enhanced efficiency of fertiliser action on forage organism growth, reduced labour cost due to high solubility of potassium monophosphate.;1 tbl, 4 ex
