NOVELTY - Liquid fertilizer comprises 20-60 g/l of potassium nitrate, 50-95 g/l of monopotassium phosphate, 3-8 g/l of dipotassium phosphate, 20-35 g/l of boric acid, 20-35 g/l of zinc-disodium EDTA, 10-25 g/l of manganese-disodium EDTA, 10-25 g/l of sodium-iron EDTA, 5-8 g/l of sodium silicate, 5-8 g/l of ammonium citrate, 0.6-1.2 g/l of sodium 5-nitroguaiacolate, 5-10 g/l of sodium dodecyl benzene sulfonate, 1-7 g/l of sodium benzoate and 0.5-0.8 g/l of organic, inorganic mixed selenium source.    USE - Bamboo shoot fertilizer.    ADVANTAGE - The bamboo shoot selenium-enriched liquid fertilizer is safe, has rich nutritional element, reasonable prescription and high utilization rate, and does not pollute environment.    DETAILED DESCRIPTION - Liquid fertilizer comprises 20-60 g/l of potassium nitrate, 50-95 g/l of monopotassium phosphate, 3-8 g/l of dipotassium phosphate, 20-35 g/l of boric acid, 20-35 g/l of zinc-disodium EDTA, 10-25 g/l of manganese-disodium EDTA, 10-25 g/l of sodium-iron EDTA, 5-8 g/l of sodium silicate, 5-8 g/l of ammonium citrate, 0.6-1.2 g/l of sodium 5-nitroguaiacolate, 5-10 g/l of sodium dodecyl benzene sulfonate, 1-7 g/l of sodium benzoate and 0.5-0.8 g/l of organic, inorganic mixed state selenium source. The organic, inorganic mixed selenium source comprises 60-75 wt.% of amino acid bound selenium whose molecular weight is 170-240, and sodium selenite. An INDEPENDENT CLAIM is included for preparing the fertilizer comprising dissolving the potassium nitrate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate in organic, inorganic mixed selenium source, adjusting the pH value to 5-6, adding sodium silicate, sodium benzoate, boric acid and ammonium citrate to obtained solution, regulating the pH value to 5.2-5.6, adding zinc-disodium EDTA, manganese-disodium EDTA and sodium-iron EDTA to the obtained solution, adjusting the pH value to 4.8-5.6 and then adding sodium 5-nitroguaiacolate, sodium dodecyl benzene sulfonate and deionized water.
