DETAILED DESCRIPTION - Selenium-rich tomato liquid fertilizer comprises 5-8 pts. wt. potassium nitrate, 4-6 pts. wt. Nostoc sphaeroides, 4-7 pts. wt. cord moss, 4-6 pts. wt. potassium chloride, 5-7 pts. wt. ammonium bicarbonate, 4-8 pts. wt. urea, 1-3 pts. wt. chalcomenite powder, 3-5 pts. wt. mulberry, 2-3 pts. wt. powdered rock phosphate, and 3-5 pts. wt. plant ash, and 6-9 pts. wt. auxiliary agent. The auxiliary agent comprises 8-10 pts. wt. shrimp, 4-6 pts. wt. konjac, 2-3 pts. wt. sodium selenite, 24-30 pts. wt. corn cob, 6-8 pts. wt. Ulva vegetable tender stem, 15-25 pts. wt. animal viscera, 3-4 pts. wt. selenium, 2-3 pts. wt. microbial inoculum, 3-5 pts. wt. EDTA chelated iron preparation, 3-5 pts. wt. EDTA chelated zinc preparation, 3-5 pts. wt. EDTA chelated calcium preparation, 3-5 pts. wt. EDTA chelated magnesium preparation, and 5-7 pts. wt. fulvic source powder; prepared by mixing corn cob, chopped shrimp, animal viscera, yeast, and microbial inoculum into fermentation pool, fermenting for 6-10 days in low oxygen condition, adding konjac fine flour, Ulva vegetable tender stem, mixing, turning, covering with canvas, anaerobically fermenting for 14-20 days at 45-55 degrees C to a water content of 40-50%, pressing fermentation heap to obtain fermentation liquid, standing for 6-10 hours to obtain fermentation clear liquid; mixing EDTA chelated iron preparation, EDTA chelated zinc preparation, EDTA chelated calcium preparation, EDTA chelated magnesium preparation, sodium selenite, and sodium source powder, and adding 240-320 times water, uniformly stirring to completely dissolve and obtain nutrition liquid, mixing fermentation clear liquid and nutrient liquid, and stirring for 10-15 minutes. An INDEPENDENT CLAIM is included for preparation of liquid fertilizer comprising mixing mulberry, Nostoc sphaeroides, and cord moss, crushing, grinding, filtering to obtain filtered liquid; mixing potassium nitrate, potassium chloride, ammonium hydrogen carbonate, and urea, adding 250-350 times water, uniformly stirring for 30-50 minutes, filtering to obtain solution-I; mixing powdered rock phosphate, plant ash, and chalcomenite powder, adding 200-400 times water, leaching for 24-36 hours at 50-70 degrees C, filtering to obtain solution-II; mixing filter liquid, solution-I, solution-II, auxiliary agent and remaining materials, stirring for 15-30 minutes, and filtering.
